I always enjoy your deburring and emphasize on a clean workspace. It might seem like a waste of time, but dealing with a bad cut for the next few days is a bigger waste of time. Avoiding the possible injury, you are far better off . Repeated bandages and time dealing with it. Plus the pain of the injury and the slowly healing wound. One of those things you learn when you get older.

So nice to see videos about the specifics of CNC setup from a genuine working professional. So much of the stuff on YT is either amateur or pure theory from applications techs. Also, Okuma has a envelope travel limit feature (I'm 90% sure Mazak does as well, but its been most of a decade since I ran one). It basically puts a soft limit on the travel in both directions in whichever axis you need. I use it a lot to basically guarantee that I won't hit my jaws or center. On jobs like this especially, it helps to reduce the pucker factor.
Duncan Thanks for your comment. The Mazak also has what they call safety barriers (I usually turn them off). That doesn't help when your in the cam software. In Esprit TNG you are working with a accurately defined model of your machine. So it will tell you in anything is wrong down to .001" or better or what ever you define. This is particularity helpful on a mill turn doing milling on the face of a part. Many of them have limited travel in the X minus direction. (Min has only 10 mm X minus travel) So if the simulation shows you going out of machine travel in the X minus direction You can change the C axis solution or machining strategy to correct the problem. Without that you would have to find out when you run the machine. This can be as little as .0001" so without this ability in the software you can't see it in a normal simulation. If you use accurate tool models it can also do the same for tool collisions. Something the Safety barriers may not tell you.
@@EdgePrecision I seem to remember being regularly frustrated with the soft limits when I was running Mazaks. We ran all Mazatrol programs, and were pretty lax on defining the tools, so that probably didn't help.

Excellent video, very well detailed. I have worked with Mazak lathes of 2 and 3 (QT-28 and QT-35) axes but that video machine is another level. Thank you
That was one of my biggest fears, "crashing the machine". Back in the day, I watch a co-worker crash one of our Kitamura's 80xi's (from the late 80's to 90's edition's), mind you, that was all I needed to see, to put the fear of god in me, to never take for granted, the amount of power these machines have at their disposal to convert into absolute violence and chaos. Those were 10 and 15 hp machines, LOL... You have my respect, as per, the 60 hp, units that you play with everyday. One missed step, and it is costly. Nice job, again on the video. The engraver pencil (although, you assumed there wouldn't be any interest in that footage), was that real time motion, and what was the type of cutter or abrasive used,... fluted, stone, diamond?.. meaning, it plowed right on through the material... Drew
I worked for GE in the gas turbine division thay had some rather large VTLs with a 20' dia. chuck 3 rams i dont even remember what the HP was but anyway i seen a cowerker setting one up and the left hand ram was down and just alittle close to the jaws when he started the machine up it winded up and hit the jaw with a bang i can still here today and continued on to the next 3 jaws Bang Bang Bang knocking all 4 jaws clean off the chuck and into the air flying till the machine came to a stop because those machines dont just come to a stop when you hit the stop button nedless to say i gained alot of respect as to the power of those machines its a good thing it was the night shift and there werent that many people there because toes jaws landed right in an spot that people would have bin if it were day time to this day i check and dobble check and tripple check as to the clearance on any chuck that i am running
At some point everyone will crash a machine. Sadly it happens. The worst one I saw was on a bullard with a 48" chuck. Guy just wasnt paying attention and restarted the program with the tool inside the part. It blew the entire 600lb assembly out of the machine through the doors and into the floor where he WAS standing. Called that guy Usain Bolt for years. Another guy went full rapid into the spindle of a SL35 and blew the Jaws off the face. I crashed a 3" boring bar on a Mori nh6300 into an alignment pin I forgot to take out of a part for line reaming. Never feels good.
User Name I’ve been indicating parts in when we turn od’s in two op’s we blend em and send them. Forgot to handle my turret up and away when I finished indicating and went to cycle start. We ran some long big boring bars in the turret at the time and it just indexed around immediately till it met my part in the chuck. Was more scared I had to go tell boss man. Haven’t made the same mistake yet though that’s true with all my crashes lmao
These videos show how incredibly meticulous your work is. If only there were shops like this here in my area, I'd apply there especially since I get my Journeyman's Card next month. (4th year tool and die maker)
Peter, great job, thanks for the video. That surface pattern seems to be from either a cold drawn bar, or a cold worked and forged bar, before its heat treatment. This part must get some serious cyclic compression loads for them to have given you such a stock.
I know how to program and prepare cnc like this, but I fall in a limbo, I am fearful about executing my programs, because one mystake last year I lose my touch, so I start seeing videos like yours to come back, because I love this kind of work. Dont know if my english was very good, if not, Im sorry, Im from Brazil. Greetings.
If you're doing a lot of this type of work it can be helpful to set up a jig made from V blocks in a mill. I used to make a heap of drive shafts and by first mounting in the cnc mill we could machine a face on both ends to a precise length, drill, tap and cut a centre taper on both ends. Made total machine time way faster
You made a comment about even though it was a 32 finish showing a pattern in the 4140. I noticed that in some I was machining this morning also. Likely has to do with the composition of the material and the affects of the heat treatment.
Honestly? The deburring was the most valuable part as far as learning is concerned. I'm not gonna be making gun drilled inconel air foils for the space shuttle on an Integrex (as awesome it is to see how that gets done!)... but damn if I couldn't use some learning on hand deburring of steel parts from a badass machinist (which you are)
Do you make your own sacrificial jaws? Or buy them by the boat load? I really enjoy your videos. Not everyday you get to see start to finish process of limited run, tool room style work on a huge machining center.
No I buy blanks and machine them. It is difficult to compete with the people that make the jaws. Often times the blanks cost not much more than the material if I made them. They must buy large quantities of the material and get better discounted prices than I can get. It just isn't worth it for me to make the blank jaws. This is also why I have a CNC tool and cutter grinder and don't grind standard end mills. The price of the centerless ground blanks at the quantities I purchase. I can't compete with big manufactures. Plus the cost of coating the tools. I only grind special tools.
Man I wish I got to run tiny parts like this on my 650H. Mine has a 26” SMW air chuck and never have parts under 20” diameter or so. Nice video tho. I like how you went through the whole process with the material prep and Jaw stetup. Most people don’t get to see all the stuff needed before even turning the part.
Nice work! Not sure what CNMG insert you used on that roughout operation. I've had success with Sandvik's CNMG 543 (r.046) PR 4305. 425sfm .026 ipr @.300-.325doc. 4140 brinell of 300-310. Not sure you want to apply that amount of load on a Integrex. But a little Nexus 550 will do a great job handling those loads. The only problem is the jorgensen conveyors can't move fast enough to evacuate the big chips up the incline. So change the little sprocket, up one tooth, to increase the speed of the belt. I rough the hell out of some parts for FMC with a positive rake holder. That way I can use all eight corners of the CNMG. Grooving I usually run at 1300sfm. I saw Y'all posted a job opening!
with a shell mill made for High feed you Can go on plunge milling . in the releaf on side of the jaws you can start of outside and plunge to the bottom near chuck in less pass . and leave 0.2 mm on side to finish the surface with a 90° shoulder taking 8/10 mm of depht each pass .
Perhaps that would work the finish wasn't critical. This just seemed easer to program my cam software doesn't do a roughing cycle that I know of with straight plunge milling. I would have to program a bunch of drilling cycles to do it. If this was something I had to do over and over say in a part that probably would be the way to go.
What takes the longest in the process of a CNC is the assembly of the machine so that the tools do not hit parts of the machine or that the tool does not hit the part!
I am checking the offset on the tool. Using a 1/2" dowel pin. It been a long time sense I made this video. I think I had not set up the threading tool before this point and had to touch it off so set the offset. I like to use a round dowel pin to touch off tools instead of shim stock or a feeler gauge. If you get the tool closer than the pins diameter than lightly press the pin in the gap. Than back off with the handle jog till the pin just passes thru. This is better than a shim because if you go solid on the shim you can chip or break the tool. also with the pin you can discern between one click (.0001") quit easily on the hand wheel. Than just subtract the diameter of the pin in Z and twice the diameter in X for a turning tool on a lathe.
a Little Tip on Jaw truning Rough: VC=350-450 m/min F=0.15-0.25 AP-5-10mm leave 1mm on the jaws use a 80° CNMG insert or something of the same Base Shape this Operation would go many times faster with these, u can aslo use Shopturn for the simple kontour of a Jaw. Finish: Just normal finish turning in 2 steps with an undercut in the corner (Form E/F should do) and for removing the corners i would have opted for "plunge milling" but this is optional
That is a very nice machine! You are lucky to run it. I thank you for the help/info . Please don't misunderstand me I'm not saying weather your way is wrong or right. What I present in a RUclips video is not necessarily the way I always do things. It sort of depends on whats in the tool changer at the time. Or just how I feel like doing it. I have done it exactly the way you describe and you are very correct. The kind of work I do, I seldom have to bore jaws. In fact it been over a year sense I have bored any. You may have noticed I have a manual 4-jaw chuck mounted on the spindle. That should give you a idea that chucking time is not significant to my type of work. The type of job I have shown in this video I seldom do. But Thanks again. I do appreciate your comment.
I notice you do job shop type work. How do you decide whether a piece needs a test part or test operation? Is that cost going toward your customer? Can you make a video of how you process an incoming job through it being recieved by a customer?
If the job is complicated and of expensive material I will do a setup piece out of inexpensive material. Just to test the program and setup. I do include the cost in the job.
..Just found your channel today...excellent contents, especially the ones about how you got started...! What is the thread pitch on the end of these (Hydraulic?) rods....12-TPI? That's a very common pitch for hydraulic stuff no matter the diameter....you mentioned nickel plating, then ground...is that going to finished in hard chrome?...usually wears better than nickel would. Even with the CNC, do you still run a 'spring pass' on threading? I was the 'Welder' in a shop with a lot of manual machines, but we had 2 guys doing hydraulic repairs...lots of rods threaded on one end for pistons....almost always 12 TPI.......then I'd weld the rod eyes back on....we had rods up to 5-6"....! cylinders up to 10" or so....and 3 stage, 27 foot for total of 81 foot for cranes....5 stage, maybe 18-20 feet for dump trucks...
Doug Ankrum Yes the thread was a 12 pitch. After I did my work the parts got ground than electrical less nickel plated. I think there is some API spec. That doesn't allow the hard chrome plating. But I'm not sure.
Thanks Eduard. The machine does have a probe. But the location of the probe is so high and to the back when deployed its hard to see when you jog the tool up to it. Also because my machine doesn't have a jog pendent (A handle jog wheel on a extension) I can't reach the jog wheel on the control and be up close to the tool setter probe to see. I find it is faster/easier to just touch off tools manually. I also like the conformation of the tools actual location (The Mazatrol shows the tools actual location in relation to the active work offset on its display) in relation to the part.
If you have a minute, could you tell me what that tool you used to deburr your soft jaws is and where you purchased it from? I run a large hurco mill everyday and that tool looks mighty useful to me! Thanks! Great video! Im jealous of your machine!
Peter, always enjoy your videos. I know that they are expensive but have you considered using a spin window in front of your camera to eliminate the coolant distorting the image of the machining operation?
It is possible to set limits on tools. Typically this is called tool life management on controls. It is possible to set a time limit number of use or load and than automatically change to a alternate tool. This kind of thing is done more a higher production setting. What I have to do is pay attention to the feel and sound of the tool running. With experience you can easily tell when a tool is dull or has failed and stop the machine.
Really enjoyed that thank you. To a newbie like myself I was wondering whether there are any viable options for a forging that starts you closer to the finished diameter but with the flanged end but have less material to shift? Not trying to be a smarty pants (I freely admit that I am just learning) but is the reason that it would be too expensive for a relatively small run?
Thanks Frank. This is manufactured to the customers spec. They say what material. I guess a forging would be closer but the quantity is so low they probably don't want to spend money on the tooling.
Nice work Peter. Seems odd they want a 32 finish if they are grinding and plating the part?? You mention when you were checked for tool clearance you also were looking at the sheet metal too. Does the machine have limit switches at all?
Bill De La Vega Yes it does. Mazak has barriers that stop the machine in Mazatrol but in a eia program these may not work. The machine has to travel in the Z axis further than this to make the tool change. So you can hit the chuck or the cabinet if the X axis is down to far before hitting the limit.
The tool setter it up high on this machine. It is difficult to see what you are doing. I find it easer and faster just to touch tools manually. On the Mazak’s control it always shows the location of the tools tip so it also verifies that the tool is offset properly. This machine also has a laser tool setter. Which by the way Mazak recommends to use for milling tools. But unfortunately it has never functioned sense I’ve owned the machine. I don’t want to spend the money to fix it.
I meant the optical pre setter you use for the horizontal, I thought I saw that in one of your vids. I've been binge watching so the vids blur together! Thanks for sharing vids.
The Speroni tool setter has a Cat 50 taper spindle. The Mazaks milling spindle is Capto 8. Now I do have a Cat 50 to C8 adapter. I would have to mount that than walk over to the optical tool setter and measure the tool than subtract the adapters length. That all would work but it would take longer than just touching off the tool at the machine. I do use the optical tool setter for the initial rough setting of boring heads for the Mazak.
why not use a round insert? i prefer rounds when im taking big long cuts. you can often take larger cuts with faster speeds. non the less, great video.
@@EdgePrecision i see! CNMG are quite versitile for roughing. but if you ever wanna try them out, i highly suggest you do, go for something from SECO. best roughing inserts there is IMO. sandvik and iscar has some great tools aswell, but for me seco takes the cake when it comes to roughing. thats just my opinion. Great video anyways :)
…...9:30.....deburr everything...good move..! Saves on the cut knuckles and thumbs later....and makes it nice for the 'next guy' if you are dealing with others...
I still have scars from my youth where my hands would hit a freshly machined surface. It didn't take long to learn to break the edges. Back then it would be a trip to the ER for stitches while today I'd just grab a bottle of Krazy Glue. :-)
Thanks Chris. A carbide burr for most things. But I have used all types of tools. It can be slowed down to 1,000 rpm with constant torque. Its speed range is 1,000-50,000 RPM.
@@EdgePrecision Thanks Peter for the quick reply, I'm sorry I should have specifically asked you about the tip you use for de-burring post machining. I've been a manual machinist for 20 years, your videos let me into the weird world of CNC, fascinating stuff.
If you are asking what hourly rate I like to get. This is what I will say about that. Because everything I own is paid for I feel ok if I get at least $100.00 per hour. I usually do quite a bit better than that. if you were buying this machine new and had financing and insurance on that you would have to make at least twice that much and maybe a little more say $225.00-250.00 a hour.
I am wondering - what is the educational path that leads to this job (my guess is that the "occupation" in this case is the owner of a high-end machine shop?). I mean - what kind of college/undergraduate degree then what? courses, specialization in some advanced-level machinery. I'll appreciate the help, thanks!
This is a somewhat difficult question to answer. It sort of depends on where in the world you live. I my case there was no traditional education path. I just learned as I went. There use to be a apprentice program here in Houston. I don’t think that exists anymore. It does in some countries. Or maybe in some places in the USA. I’m not sure. As far as business you could go to school for that. But the rest is more on the job training. I myself am a self taught machinist and to a smaller degree business. I don’t know if that helps much.
Ram shaft, as in 'hydraulic' cylinder ram..? I'm guess that thread is 12 TPI, seems real common for just about any hydraulic stuff....and that 3" turned area will be getting hard chrome??
No electric less nickel it said on the print. My friend in R&D once told me they don’t like to use hard chrome in sub sea stuff. I can’t remember why though. And I can’t ask him he passed away a number of years ago.
I think if I remember it had to do with the bond of the hard chrome. It tends to flake off where the Nickel doesn't. But I'm not sure. This could relate to corrosion getting under the chrome.
@@EdgePrecision Engine cylinder liners are often hard Chromed. And the main cause of their failure is indeed the Chrome coming off in chunks. Nickel doesn't hold up to the heat as well so that is why it gets plated over. What do you do with a bad cylinder liner? Send it back and they machine it down to base metal again. And then build it back up with Nickel and then Chrome. It is cheaper than buying a new liner, if you can even get one. In cold work such as undersea valves, the Nickel will protect the stem as well as Chromium would. Surprised they don't just spec that ram as 304L Stainless.
Nice work and great videos. Try running the 4140 without coolant and that may get rid of the spotty look to the finish. Of course only if the insert can run dry. I run iscar ic908 with a "pp" chip-breaker dry in 4140 with great results for insert life. I also run Sandvik 4325 with a qm chip-breaker dry aswell. What kind of inserts do you use in this video?
adavid7901 , I will have to get back to you on that to be exact. The roughing insert is a Iscar one of their newer grades. The groove a Sandvik and the others Sumotomo.
Edge Precision sumitomo make great inserts for heavy milling .. in my experience i work with 50/63/80 mm shoulder mill and 45° facing . on facing on my iso40 i remove 4 mm depht on 42nicr 65% engagement at 0.23 mm/t .. heavy chip !
adavid7901, I have a better answer for you on the inserts. The roughing insert is a Iscar CNMG 432-TF IC8250 The finishing inserts are Sumitomo DNMG 432EMU AC520U Shaft OD and VBMT331ESU AC520U Pin OD and Rough Thread Relief. Groove Sandvik N132H2-0396-0002-GF 1105 Thread Vardex full profile lay down .375 IC grade VTX. These may not be the best grades for this material they are just what I had on hand without having to buy new inserts. The Iscar insert had no trouble roughing the whole part with one tip. It would have done more I just indexed it every part to be safe. The other inserts gave no trouble either.
Edge Precision I really like the sumitomo inserts in a cnmg same grade and chip breaker I run them in inconel 725 at 200sfm at .009/rev and .09 doc. And they last longer then a Sandvik ceramic. The iscar tf chip breaker is awesome aswell. I haven't used the 8250 grade but I'm sure it's great. Most of my turning with iscar was with IC908 or IC3028. I found The Sandvik 1105 grade works really good in stainless but I like the 4325 better for an all around grade. Keep up the great bids and work.
Great video Peter! What is your experience with Espirit's machine simulation, does it provide good collision detection/prevention? Also, that deburring tool looks superb, what were you using for the tip and what are your general recommendations for pencil grinders?
Norman J , Esprit's collision detection works good if the tools and holders are properly specified properly. The grinder shown in the video I've owned for over ten years. At first I resisted buying it because of the cost. It has given no trouble it is much more powerful than a small air grinder like a Dotco but a little heavier. Even at lower RPM it has power because it's constant torque.
Si vous demandez quel cône de broche? Cette machine a un cône de broche capto 8. Je n'utilise pas les plaquettes tournantes Sandvik car elles facturent beaucoup d'argent pour leurs plaquettes.

Dru Bradley the beginning of the scene was in normal speed. The grinder is variable speed from 0-50,000 rpm. I was using a carbide burr at 40,000 rpm.
I crashed a Mori-Seiki SL 25 in the beginning of "my career" and it was enough to scare me :D
I worked for GE in the gas turbine division thay had some rather large VTLs with a 20' dia. chuck 3 rams i dont even remember what the HP was but anyway i seen a cowerker setting one up and the left hand ram was down and just alittle close to the jaws when he started the machine up it winded up and hit the jaw with a bang i can still here today and continued on to the next 3 jaws Bang Bang Bang knocking all 4 jaws clean off the chuck and into the air flying till the machine came to a stop because those machines dont just come to a stop when you hit the stop button nedless to say i gained alot of respect as to the power of those machines its a good thing it was the night shift and there werent that many people there because toes jaws landed right in an spot that people would have bin if it were day time to this day i check and dobble check and tripple check as to the clearance on any chuck that i am running
At some point everyone will crash a machine. Sadly it happens. The worst one I saw was on a bullard with a 48" chuck. Guy just wasnt paying attention and restarted the program with the tool inside the part. It blew the entire 600lb assembly out of the machine through the doors and into the floor where he WAS standing. Called that guy Usain Bolt for years. Another guy went full rapid into the spindle of a SL35 and blew the Jaws off the face. I crashed a 3" boring bar on a Mori nh6300 into an alignment pin I forgot to take out of a part for line reaming.
Never feels good.
User Name I’ve been indicating parts in when we turn od’s in two op’s we blend em and send them. Forgot to handle my turret up and away when I finished indicating and went to cycle start. We ran some long big boring bars in the turret at the time and it just indexed around immediately till it met my part in the chuck. Was more scared I had to go tell boss man. Haven’t made the same mistake yet though that’s true with all my crashes lmao
Being a machinist takes so much skill
Good narrative skills I like your videos and I only watched 2 of them lol
I wish some people I know used your good pratices. A first class example of good practice and planing .
I used to make those Ram Shafts back in the day. Along with Door Locking Bars, Anti Rotation Bars, Segments, Pistons etc.
I dig your de burring set up and love watching it.
师傅您工作真的 很认真 我们全世界的年轻机械加工工人都需要向您学习。
These videos show how incredibly meticulous your work is. If only there were shops like this here in my area, I'd apply there especially since I get my Journeyman's Card next month. (4th year tool and die maker)
Peter, great job, thanks for the video. That surface pattern seems to be from either a cold drawn bar, or a cold worked and forged bar, before its heat treatment. This part must get some serious cyclic compression loads for them to have given you such a stock.
Your videos are so good! I don't know why I stumbled upon your channel just a few days ago.
They make a turning holder to put the I believe B axis at 45 degrees to solve clearance issues. We use them where I work
Love your vids man. For a novice like me there are so great
I know how to program and prepare cnc like this, but I fall in a limbo, I am fearful about executing my programs, because one mystake last year I lose my touch, so I start seeing videos like yours to come back, because I love this kind of work.
Dont know if my english was very good, if not, Im sorry, Im from Brazil.
Greetings.
enjoy your series. I like the set ups for work holding. that's a real talent
Very nice series about this part, it really takes lot of experience and work to do something like this.
Thanks for telling your secret recipes!
If you're doing a lot of this type of work it can be helpful to set up a jig made from V blocks in a mill. I used to make a heap of drive shafts and by first mounting in the cnc mill we could machine a face on both ends to a precise length, drill, tap and cut a centre taper on both ends. Made total machine time way faster
You made a comment about even though it was a 32 finish showing a pattern in the 4140. I noticed that in some I was machining this morning also. Likely has to do with the composition of the material and the affects of the heat treatment.
Another awesome video! Great job! You really deserve way more subscribers than you have.
You do great work. Thank you for the video.
Haha I have the exact same calculator. I'ma big fan of your videos. And strive to improve my machining and video skills to your level.
Honestly? The deburring was the most valuable part as far as learning is concerned. I'm not gonna be making gun drilled inconel air foils for the space shuttle on an Integrex (as awesome it is to see how that gets done!)... but damn if I couldn't use some learning on hand deburring of steel parts from a badass machinist (which you are)
Thanks. Wow you say stuff like that its liable to go to my head.
Lo que mas me gusta es que le ponga el refrigerante para cuidar el inserto, aun sin saber nada ne me parece bien ver chispas durante los trabajos
Do you make your own sacrificial jaws? Or buy them by the boat load? I really enjoy your videos. Not everyday you get to see start to finish process of limited run, tool room style work on a huge machining center.
No I buy blanks and machine them. It is difficult to compete with the people that make the jaws. Often times the blanks cost not much more than the material if I made them. They must buy large quantities of the material and get better discounted prices than I can get. It just isn't worth it for me to make the blank jaws. This is also why I have a CNC tool and cutter grinder and don't grind standard end mills. The price of the centerless ground blanks at the quantities I purchase. I can't compete with big manufactures. Plus the cost of coating the tools. I only grind special tools.
Thanks.
Man I wish I got to run tiny parts like this on my 650H. Mine has a 26” SMW air chuck and never have parts under 20” diameter or so. Nice video tho. I like how you went through the whole process with the material prep and Jaw stetup. Most people don’t get to see all the stuff needed before even turning the part.
can last all day i love to watch
Nice work! Not sure what CNMG insert you used on that roughout operation. I've had success with Sandvik's CNMG 543 (r.046) PR 4305. 425sfm .026 ipr @.300-.325doc. 4140 brinell of 300-310. Not sure you want to apply that amount of load on a Integrex. But a little Nexus 550 will do a great job handling those loads. The only problem is the jorgensen conveyors can't move fast enough to evacuate the big chips up the incline. So change the little sprocket, up one tooth, to increase the speed of the belt. I rough the hell out of some parts for FMC with a positive rake holder. That way I can use all eight corners of the CNMG. Grooving I usually run at 1300sfm. I saw Y'all posted a job opening!
buen video..gracias por tu tiempo
Gracias de nuevo Tr Precision!
На таком оборудовании для токаря работать - удовольствие.
I like watching you debur with that little rig.
with a shell mill made for High feed you Can go on plunge milling . in the releaf on side of the jaws you can start of outside and plunge to the bottom near chuck in less pass . and leave 0.2 mm on side to finish the surface with a 90° shoulder taking 8/10 mm of depht each pass .
Perhaps that would work the finish wasn't critical. This just seemed easer to program my cam software doesn't do a roughing cycle that I know of with straight plunge milling. I would have to program a bunch of drilling cycles to do it. If this was something I had to do over and over say in a part that probably would be the way to go.
leave in the de-burring and filing. it is a nice to see those small finishing operations that are so necessary.
amazing work with the jaws.
Good work on the jaws.
Always trying to think ahead. Can't wait for the next video.
Wow 60 hp spindle that’s awesome and impressive man what amazing machine you got there good job operating it to
...moc pěkná ukázka přípravy a super camera. Zdravím z Tschech. 👉 👍👍✊🙋
Josef Děkuji, vážím si toho.
You keep it interesting throughout the whole video, good job and youve earned some subs from this video
I'm curious if it's possible to program in the geometry of the spindle, jaws, etc. so that the CAM software can help you avoid crashing...
Yes in the cam software it is possible to have a model of the machine for simulation purposes.
What takes the longest in the process of a CNC is the assembly of the machine so that the tools do not hit parts of the machine or that the tool does not hit the part!
What are you doing on 23:23? check that the tool is well measured?
I am checking the offset on the tool. Using a 1/2" dowel pin. It been a long time sense I made this video. I think I had not set up the threading tool before this point and had to touch it off so set the offset. I like to use a round dowel pin to touch off tools instead of shim stock or a feeler gauge. If you get the tool closer than the pins diameter than lightly press the pin in the gap. Than back off with the handle jog till the pin just passes thru. This is better than a shim because if you go solid on the shim you can chip or break the tool. also with the pin you can discern between one click (.0001") quit easily on the hand wheel. Than just subtract the diameter of the pin in Z and twice the diameter in X for a turning tool on a lathe.
Thanks for the rare, these kind of knowledge are hard to learn in home shop.
a Little Tip on Jaw truning
Rough:
VC=350-450 m/min
F=0.15-0.25
AP-5-10mm
leave 1mm on the jaws
use a 80° CNMG insert or something of the same Base Shape
this Operation would go many times faster with these, u can aslo use Shopturn for the simple kontour of a Jaw.
Finish:
Just normal finish turning in 2 steps with an undercut in the corner (Form E/F should do)
and for removing the corners i would have opted for "plunge milling" but this is optional
There are indeed many different way to do things. Thanks!
@@EdgePrecision just an idea, please try it yourself i use it everytime i have to do stuff, my machine is the CTX Gamma 2000Tc
That is a very nice machine! You are lucky to run it. I thank you for the help/info . Please don't misunderstand me I'm not saying weather your way is wrong or right. What I present in a RUclips video is not necessarily the way I always do things. It sort of depends on whats in the tool changer at the time. Or just how I feel like doing it. I have done it exactly the way you describe and you are very correct. The kind of work I do, I seldom have to bore jaws. In fact it been over a year sense I have bored any. You may have noticed I have a manual 4-jaw chuck mounted on the spindle. That should give you a idea that chucking time is not significant to my type of work. The type of job I have shown in this video I seldom do. But Thanks again. I do appreciate your comment.
@@EdgePrecision alright
I notice you do job shop type work. How do you decide whether a piece needs a test part or test operation? Is that cost going toward your customer? Can you make a video of how you process an incoming job through it being recieved by a customer?
If the job is complicated and of expensive material I will do a setup piece out of inexpensive material. Just to test the program and setup. I do include the cost in the job.
That finish is from using coolant. I never run coolant on 4140 for finish passes just for roughing.
I realised that too
why didn't you ramp down on the rough milling jaws cycle using y axis?
Love your videos! What motorize deburing tool is that?
..Just found your channel today...excellent contents, especially the ones about how you got started...! What is the thread pitch on the end of these (Hydraulic?) rods....12-TPI? That's a very common pitch for hydraulic stuff no matter the diameter....you mentioned nickel plating, then ground...is that going to finished in hard chrome?...usually wears better than nickel would. Even with the CNC, do you still run a 'spring pass' on threading?
I was the 'Welder' in a shop with a lot of manual machines, but we had 2 guys doing hydraulic repairs...lots of rods threaded on one end for pistons....almost always 12 TPI.......then I'd weld the rod eyes back on....we had rods up to 5-6"....! cylinders up to 10" or so....and 3 stage, 27 foot for total of 81 foot for cranes....5 stage, maybe 18-20 feet for dump trucks...
Doug Ankrum Yes the thread was a 12 pitch. After I did my work the parts got ground than electrical less nickel plated. I think there is some API spec. That doesn't allow the hard chrome plating. But I'm not sure.
Muito bonito seu trabalho, muito eficaz ,que comando é esse ?
Você quer dizer que controle a máquina tem? Nesse caso, é um Mazatrol 640M pro.
@@EdgePrecision obrigado Edge👍
Great!!
For setup thread turn why you use blocks, machine not have probe?
Thanks Eduard. The machine does have a probe. But the location of the probe is so high and to the back when deployed its hard to see when you jog the tool up to it. Also because my machine doesn't have a jog pendent (A handle jog wheel on a extension) I can't reach the jog wheel on the control and be up close to the tool setter probe to see. I find it is faster/easier to just touch off tools manually. I also like the conformation of the tools actual location (The Mazatrol shows the tools actual location in relation to the active work offset on its display) in relation to the part.
Not understand-me ,you best operator machine cnc or video?)))
Best regards from operator Anca & Rollomatic!)
If you have a minute, could you tell me what that tool you used to deburr your soft jaws is and where you purchased it from? I run a large hurco mill everyday and that tool looks mighty useful to me! Thanks! Great video! Im jealous of your machine!
It's always good to see some of the tedious work just to see the reality of some of the work required to do a job right.
just a suggestions make a small air hose pointed towards your camera lens with a constant stream of air why your machining with high pressure coolant.
You need to watch my other videos. I have already done that.
Peter, always enjoy your videos. I know that they are expensive but have you considered using a spin window in front of your camera to eliminate the coolant distorting the image of the machining operation?
19:00 How did you know that the cutter broke, Mazak is able to detect the breakage of the cutter?
It is possible to set limits on tools. Typically this is called tool life management on controls. It is possible to set a time limit number of use or load and than automatically change to a alternate tool. This kind of thing is done more a higher production setting. What I have to do is pay attention to the feel and sound of the tool running. With experience you can easily tell when a tool is dull or has failed and stop the machine.
great video Peter
Nice, the old girl does it well
Really enjoyed that thank you. To a newbie like myself I was wondering whether there are any viable options for a forging that starts you closer to the finished diameter but with the flanged end but have less material to shift? Not trying to be a smarty pants (I freely admit that I am just learning) but is the reason that it would be too expensive for a relatively small run?
Thanks Frank. This is manufactured to the customers spec. They say what material. I guess a forging would be closer but the quantity is so low they probably don't want to spend money on the tooling.
@@EdgePrecision thanks for the reply and thanks again for the informative video.
I want to be a world class machinist one day
Nice work Peter. Seems odd they want a 32 finish if they are grinding and plating the part?? You mention when you were checked for tool clearance you also were looking at the sheet metal too. Does the machine have limit switches at all?
Bill De La Vega Yes it does. Mazak has barriers that stop the machine in Mazatrol but in a eia program these may not work. The machine has to travel in the Z axis further than this to make the tool change. So you can hit the chuck or the cabinet if the X axis is down to far before hitting the limit.
So you're loading the program from your CAM software, that is an eia program?
Bill De La Vega That's what Mazak calls a G code program. You have to save the program with a .eia suffix for Mazak to recognize it.
It looks like you have that high feed mill in a set screw holder. Can you plunge mill with a set screw tool holder?
Please help me. I search your video when you doing tread with tap on turn mill machin in jog weal.
So, Why aren't you using your tool setter for the Mazak? Seems like the way to go, and you have it.
The tool setter it up high on this machine. It is difficult to see what you are doing. I find it easer and faster just to touch tools manually. On the Mazak’s control it always shows the location of the tools tip so it also verifies that the tool is offset properly. This machine also has a laser tool setter. Which by the way Mazak recommends to use for milling tools. But unfortunately it has never functioned sense I’ve owned the machine. I don’t want to spend the money to fix it.
I meant the optical pre setter you use for the horizontal, I thought I saw that in one of your vids. I've been binge watching so the vids blur together! Thanks for sharing vids.
The Speroni tool setter has a Cat 50 taper spindle. The Mazaks milling spindle is Capto 8. Now I do have a Cat 50 to C8 adapter. I would have to mount that than walk over to the optical tool setter and measure the tool than subtract the adapters length. That all would work but it would take longer than just touching off the tool at the machine. I do use the optical tool setter for the initial rough setting of boring heads for the Mazak.
Any details on that "pencil grinder" that you could post? Cheers.
Go to this link. nskamericacorp.com/product/category/Espert-500/12
why not use a round insert? i prefer rounds when im taking big long cuts. you can often take larger cuts with faster speeds. non the less, great video.
I just used what I had. Didn't have tooling for a round insert.
@@EdgePrecision i see! CNMG are quite versitile for roughing. but if you ever wanna try them out, i highly suggest you do, go for something from SECO. best roughing inserts there is IMO. sandvik and iscar has some great tools aswell, but for me seco takes the cake when it comes to roughing. thats just my opinion.
Great video anyways :)
…...9:30.....deburr everything...good move..! Saves on the cut knuckles and thumbs later....and makes it nice for the 'next guy' if you are dealing with others...
I still have scars from my youth where my hands would hit a freshly machined surface. It didn't take long to learn to break the edges. Back then it would be a trip to the ER for stitches while today I'd just grab a bottle of Krazy Glue. :-)
Excellent work.
Che figata quando hai tempo per cazzeggiare e budget illimitato...
Lavoro come voglio perché posso. Non devi rispondere a nessun capo.
Excellent video as always. What kind of tip do you use in you pencil grinder, a burr or an abrasive tip?
Thanks Chris. A carbide burr for most things. But I have used all types of tools. It can be slowed down to 1,000 rpm with constant torque. Its speed range is 1,000-50,000 RPM.
@@EdgePrecision Thanks Peter for the quick reply, I'm sorry I should have specifically asked you about the tip you use for de-burring post machining. I've been a manual machinist for 20 years, your videos let me into the weird world of CNC, fascinating stuff.
That is what I'm talking about the NSK pencil grinder.
@@EdgePrecision Thanks
why kind of pencil grinder do you use?
Do a search for NSK Espert 500.
that HUGE dial holder, HUGE
Great video Peter !
I wonder . What is the mazak 's cost per hour?
If you are asking what hourly rate I like to get. This is what I will say about that. Because everything I own is paid for I feel ok if I get at least $100.00 per hour. I usually do quite a bit better than that. if you were buying this machine new and had financing and insurance on that you would have to make at least twice that much and maybe a little more say $225.00-250.00 a hour.
I am wondering - what is the educational path that leads to this job (my guess is that the "occupation" in this case is the owner of a high-end machine shop?). I mean - what kind of college/undergraduate degree then what? courses, specialization in some advanced-level machinery. I'll appreciate the help, thanks!
This is a somewhat difficult question to answer. It sort of depends on where in the world you live. I my case there was no traditional education path. I just learned as I went. There use to be a apprentice program here in Houston. I don’t think that exists anymore. It does in some countries. Or maybe in some places in the USA. I’m not sure. As far as business you could go to school for that. But the rest is more on the job training. I myself am a self taught machinist and to a smaller degree business. I don’t know if that helps much.
@@EdgePrecision Thank you for the response. I live in the US. So it starts with vocational school?
Try with some sort of spinning shield (sapphire glass fine polished) , centrifugal force probably will get off coolant.
Ram shaft, as in 'hydraulic' cylinder ram..? I'm guess that thread is 12 TPI, seems real common for just about any hydraulic stuff....and that 3" turned area will be getting hard chrome??
No electric less nickel it said on the print. My friend in R&D once told me they don’t like to use hard chrome in sub sea stuff. I can’t remember why though. And I can’t ask him he passed away a number of years ago.
@@EdgePrecision OK, sub sea...they like nickel better for corrosion resistance..
I think if I remember it had to do with the bond of the hard chrome. It tends to flake off where the Nickel doesn't. But I'm not sure. This could relate to corrosion getting under the chrome.
@@EdgePrecision Engine cylinder liners are often hard Chromed. And the main cause of their failure is indeed the Chrome coming off in chunks. Nickel doesn't hold up to the heat as well so that is why it gets plated over. What do you do with a bad cylinder liner? Send it back and they machine it down to base metal again. And then build it back up with Nickel and then Chrome. It is cheaper than buying a new liner, if you can even get one. In cold work such as undersea valves, the Nickel will protect the stem as well as Chromium would. Surprised they don't just spec that ram as 304L Stainless.
Nice work and great videos. Try running the 4140 without coolant and that may get rid of the spotty look to the finish. Of course only if the insert can run dry. I run iscar ic908 with a "pp" chip-breaker dry in 4140 with great results for insert life. I also run Sandvik 4325 with a qm chip-breaker dry aswell. What kind of inserts do you use in this video?
adavid7901 , I will have to get back to you on that to be exact. The roughing insert is a Iscar one of their newer grades. The groove a Sandvik and the others Sumotomo.
Edge Precision sumitomo make great inserts for heavy milling .. in my experience i work with 50/63/80 mm shoulder mill and 45° facing . on facing on my iso40 i remove 4 mm depht on 42nicr 65% engagement at 0.23 mm/t .. heavy chip !
adavid7901, I have a better answer for you on the inserts. The roughing insert is a Iscar CNMG 432-TF IC8250 The finishing inserts are Sumitomo DNMG 432EMU AC520U Shaft OD and VBMT331ESU AC520U Pin OD and Rough Thread Relief. Groove Sandvik N132H2-0396-0002-GF 1105 Thread Vardex full profile lay down .375 IC grade VTX. These may not be the best grades for this material they are just what I had on hand without having to buy new inserts. The Iscar insert had no trouble roughing the whole part with one tip. It would have done more I just indexed it every part to be safe. The other inserts gave no trouble either.
Edge Precision I really like the sumitomo inserts in a cnmg same grade and chip breaker I run them in inconel 725 at 200sfm at .009/rev and .09 doc. And they last longer then a Sandvik ceramic. The iscar tf chip breaker is awesome aswell. I haven't used the 8250 grade but I'm sure it's great. Most of my turning with iscar was with IC908 or IC3028. I found The Sandvik 1105 grade works really good in stainless but I like the 4325 better for an all around grade. Keep up the great bids and work.
Edge Precision the 8250 grade and tf chipbreaker are exactly what you should be running. Good job
What model of Mazak is that? Thanks
It’s a e650H.
Leave the deburring int !!! That is the best part.
another great video. how fast were you turning when you faced the part. love that your videos are longer and very detailed. keep it up!
raider , l had it set to 650 surface feet with a 1000 RPM limit. Thanks.
Great video Peter! What is your experience with Espirit's machine simulation, does it provide good collision detection/prevention? Also, that deburring tool looks superb, what were you using for the tip and what are your general recommendations for pencil grinders?
Norman J , Esprit's collision detection works good if the tools and holders are properly specified properly. The grinder shown in the video I've owned for over ten years. At first I resisted buying it because of the cost. It has given no trouble it is much more powerful than a small air grinder like a Dotco but a little heavier. Even at lower RPM it has power because it's constant torque.
