A tip we use in our machine shop, after you run your threads come back with your OD turning tool for a skim over the top of the threads then run the last pass of the threading tool again. Leaves amazing threads with no need to file by hand.
Came here to to say this, and to use a smaller radius tool and profile the radius. The CNC doesn't need to plunge cut with the right radius to get the final shape.
I got myself an entry level cnc router for xmas ... and Oh My Lord!!! You are 100% correct ... reminds me of computer programming back in the 80's .. we swore by GIGO ..garbage in, garbage out.
Adam, a little tip for you on repeating stick outs: call up tool 1 and bring it into something like X4Z0 and hand jog into X0 with the stock back in the chuck jaws. Pull the stock out until it touches the tool. It acts like a stop and your stickouts will all be within a few thou if you're repeating ops like this.
Hi Adam, please use the wear fields in the tool offset table for the tool correction offsets. When you change the tool length youre in grave danger of crashing your machine if you mistype. Thats what the wear fields are for. Best, Martin
At first I was a bit worried that a superb precision machinist channel might be ruined by the introduction of CNC. But I was completely wrong: This promises to be a fascinating journey where a superb machinist learns to teach a machine to do work to HIS standards - it's clearly not just 'plug and play' as I'd assumed!
Can I just say how happy it made me to see the precision that even the pig mat was placed on the table in the beginning. I am sure it makes many of us very happy to see it not out of square with the table. Thanks Adam!
To get rid of the burrs on the thread, either run topping inserts which automatically crest the very top of the thread, or take a spring/very very lite finishing pass over the thread OD. Great work, keep it up!
Great video as always. You inspired me to get my own machines. Not much, but a little Clausing 8520 and a 14x42 Logan have given me hours of entertainment. I’d venture to say that I’ve been able to run them from what I’ve learned from you. I thank you.
You are brave to show what it takes to learn new technology and I hope it inspires more to learn this too. I really enjoy your videos and I wish you continued success.
I program with solidcam for the last 10 years, I program in metric, but I always leave 0.1mm in my roughing program, then come back with a finish pass so it's very light on the cut and eliminates all chatter with the tooling, machine and stock. Always always always run a finish pass for a quality finish and to size more consistently 👌 love watching you grow with cnc. Old school subscriber.
I have no suggestions or criticisms, but just plain awe at your courage to learn CNC work. Looking through the comments here you may be able to learn from some and get a smile from others. Thanks much for sharing your experience with us.
For a better chuck key check out what Peter uses at Edge Precision. It's a ratchet where the handle can extend and a short adapter to suit the chuck. As soon as I saw that I had to get one, and now use it all the time, for lots of things.
Just a bit of advice Adam. When your adjusting your sizes you should be adding or subtracting using the X Wear and Z Wear offset box for the tools not adjusting the X Length and Z Length which you get using the tool probe. You might also need to ask miltronics if your tool table is set to adjust diameter or radius because I have a feeling when you adjusted your size you actually doubled it which is why your size came out double what you expected which tells me you need to adjust only for the radius not diameter.
Happy New Year. Love your videos and have learned a lot from you. On the fuzzys after threading: I was taught that after the threading, do another finish OD pass with your turning tool and then a final spring pass with the threading tool. This takes the burrs off the OD and the final threading spring pass takes the ones off that the OD tool folded in.
He's fully aware of that in manual machining, he was saying he needs to learn how to program that into the CNC program, or learn how to do a manual cleanup pass after the program runs.
I could watch you make art all day mate. The cnc form of it is just as satisfying as the manual version. Thanks for bringing us along for the ride man.
Sooo nice to see you starting to learn this machine. I can see already now that your skills to try this out with curiosity, trying and see the result, is already reaping success. Looking forward to see a mix of manual and CNC material on you channel. :-)
On your tool comp on the threading tool, you should've only changed it by 0.0005" instead of 0.001". You take 0.0005" on each side which gives you the full 0.001". Nice work!
There isn’t a wear offset on the tools? Those little burrs on the OD finish could be improved by doing two things. Use a different tool for your finish cut at a higher surface footage or speed. I’m not sure but by the sound of the video. Are you running in constant surface speed on your turning cuts? Or maybe you have limited the speed in the program. Typically to make a thread relief I use a 35 degree diamond turning tool. I turn down a 45 degree angle into the relief into the relief. Rough the relief and then do your finish OD cut with that tool with the thread relief all in that finish cut.
Getting his cutting forces pushing down, instead of pulling up will help as well. Especially in that little machine. It will help his diameter control immensely. And, no offense intended, but he's trying to run it like a manual. Lighter D.O.C, lighter semi-finish and finish passes, even with the same tool, will do wonders.
@@tedsaylor6016 Ted I just saw this comment. I wouldn’t mind it but I don’t know when it could be. All my spare time for trips going to Mexico for my building project. I did once meet Adam at the first Good of the land meet up here in Texas. I think for being totally new to CNC Adam is doing real well. That manual experience is really a big help.
Very cool! I’d love to see more of the programming side of things, like how you configure the individual steps, what params you have to set and how it looks on the UI.
Nice little project! I would have loved seeing you do the actual programming, the tool setup, ... Just to see how that works, what thoughts you go through, and so on. And for you it would be a beneficial repetition to memorize all that even better and also get a better overview how to navigate the software. Happy New Year!
Doing very nice Mr Adam. Whooshing you and yours a wonderful New Year and great adventures coming with your new shop. I’m enjoying and looking to see each and every video.
Nice job! It’s been a long time since I’ve watched your vids. You have come a long way from your first vids so long ago lol! It’s making how technology can make our lives so much easier and productivity can improve like this. Nice job getting the concrete machine. It is definitely the way!
Nice to see you using this machine, The nice thing about CNC lathes is you don't need to use those types of radius tools like you would on a manual lathe. You can program a DNMG type insert to go in there and put what ever shape you want. I'm not criticizing, just reminding you. I'm not very good yet at programming from scratch yet. I run and edit alot of programs on CNC lathes at my day job. Love it. We usually rough everything with CNMG on tool #2 then finish with DNMG tool #1. Pretty cool how you can program those radius in with a normal cutting tool or even use radius tools moving in the program, not just straight in. Thanks for the video, I love these CNC videos.
I ran a Bridgeport mill with Hurco CNC control back in 76 and 77. I had my supervisor there with me to teach me how to work it, but I couldn’t imagine trying to do it by myself. I’m sure this time next year you’ll be proficient at CNC programming and will use them for most of your work
You are learning fast. If I may, a few tips. With a long bar, use a sleeve inside the spindle tube so the bar can't whip around. That long bar will amplify any chatter in the cut. For cutting steel, use a different tool to finish because the roughing tool will wear and need constant adjustment if it's also finishing. After threading, make another finish cut to remove burrs. Then do another threading cut to remove the burr left by the second finish pass. If there is no ring gage, use a nut to check the threads all the way to the relief. The threading should be programmed right up to the far end of the relief--it won't hit the wall.
I usually re-cut the theead major diameter and take another spring pass on the threads to remove the burrs on threaded parts. Easy peasy on CNC machines.
The advantage and speed of the CNC is incredible, in the time of going to look for a clock to time the time in which the work is completed and boom, in the blink of an eye the work is finished !! How fast !! regards
Hey abom, as I'm native on a CNC lathe (learned manual lathing after CNC) it's fascinating to see your progress, you can tell that you have the knowledge of the basics pretty dialed in :) For your threading operations you should consider full profile inserts instead of the partial, much cleaner results. My goto insert would be a DNMG instead of the CNMG on this size of machine and kinda rough stuff. With a DNMG you dont need the grooving operation. And i dont know your control, but there should be a table for wear correction, normally you do your tool corrections in this table and not in the tool data itself.
Adam you’ll want to add or subtract in the “wear” tab not the offset # your wear tab will be either radial or diameter. Add positive value at first then subtract your way to size.
Huge respect , congrats on your machines. As soon as you are comfortable , I’d advise you to get a used Japanese cnc lathe ( hydraulic chucker) . Old mori , Okuma , etc. chatter issues and repeatability is great, even on 20 year old machines . I started doing what you do, so I know the learning curve.
Hi ! I wish you an happy new year to you and your family. It will nice to have a video to explain how you install and adjust the position of the different tools. Best regards from France.
I would love to see a video on how you programmed the lathe to do that operation. It might be boring for some, but I think a few people would be interested in learning what you have to do to make a part like you just made. Thanks for all the great videos and advice. Keep up the great work.
Adam, consider this for thread relief now that you are on a cnc. I noticed you have a vnmg holder, 35* OD tool. The beauty of that tool is you can produce a 45* backside chamfer. Use that tool to create the back thread relief down to about 0.01 past the minor diameter.
You can top the threads leave like .003 or less usually 1-3 thou radially on before you finish the threads then take your dia right to size then run the threader once for your final pass. For the chatter I would start with reducing your spindle speed for the threads and with the groove like you said use a smaller one and take multiple cuts.
My son, for a short time, was working for a CNC shop as a temp. He still had to manually deburr every part as it came out of the machine. Maybe the burrs are typical and you'll always need to file them.
Happy New Year and thanks for the video. You only need two tools for the job you showed in the video. T1 Planing ,linear turning and thread release T2 Threading
I'd say maybe the cuts are a bit aggressive for the set up? And yes as some others have mentioned, a spring pass can be added in to de-bur the thread. But that is the learning process and I think you are smashing it with the cnc learning curve so keep pushing 🤛
Interesting thread measurement tool, I don’t remember them or they were not though of when I was a young apprentice. First time I’ve seen them. I learned on the old 3 wire and still have them 25 years later.
@17:38 Use a full profile Insert , that insert will Top off the threads Major Dimension too , you won't have burr, Or if I don't have one generally I make a finish pass followed by a thread repass not efficient but I get clean threads , the Tooling representative will surely have a solution too
@@StefanGotteswinter Well I didn't specify but I meant about CNC machine operations. lol Otherwise I do know a lot about a little and a little about a lot. 🙂
Those CMC$ will be a godsend when you need to batch out a lot of identical parts. That will let you work on other projects while the mind numbing process of making the same small part over and over and over it’s done by the CNC. Awesome
Great job, I noticed your screwcutting tool was still taking a big cut on last pass, you need a spring pass, a CNC machine like this with an insert like that will make mirror finish threads with no burrs.
Topping inserts are the only way to not have burrs unless you do a finish turning pass after the threading. You can run the finish pass backwards and it will debur the thread on the chamfer.
Looks great Adam, I'm sure the CNC machine will make things go a lot quicker for you. Hope you had a good Christmas holiday, and wishing you and Abby all the very best in 2023. Thank you for sharing all the great video content you provide for us on RUclips. Always appreciate the tips and tricks you mention for the machinists out there. Cheers and Blessings 👍🙏.
Hi, I have noticed that 250rmp makes less tool deflection and have more control on it. Full profile insert on threads is my recommendation for better results without filing afterwards 💪 I have in siemens control and there is cycle for thread relief, easy to make with vnmg tool👌 Keep on training and there it comes that same confidence that you have with manual machines💫
Adam, talk to Milltronics about how their lathes are setup. When you change a tool geometry offset by 0.001" that will likely be a radial change. Some controls have options for making the wear offsets radial or diametric. I've got my lathes set up in diametric but your one thou change may have moved two thou just because it is a diametric change, not a radial change.
@@richardjones7249 Adam is drinking from a firehose right now and this is a simple thing to miss or forget during (or since) training. I have been running my specific machines here for a few years and still constantly have questions for the applications guys. I'm just trying to help him the best I can because he taught me how to run a lathe for free on the internet and now I am actually in a position to potentially give back.
At around 2:54 make note of what diameter is on the display. 3:01 pause program-measure-make that adjustment here then rest should be gnats ass without the scrap. Gimme more Milltronics content!!!
10:20 Perhaps do a .010" cleanup cut on the OD of your material before starting to cut threats, to ensure the overall final diameter.? 11:25 aha fine minds think alike you did it.! Happy next year
I went back and rewatched the video to see if I missed something. He said he was going to figure out how to program the job using "conversational". Next, he has the metal rod in the machine, but no programming. Later we see a screen with numbers already filled in for a program file "Shaft Threaded End" with no explanation as to how he got there. There is chattering which could be reduced or eliminated with maybe more and lighter passes. It would have been enlightening to follow through with that thought. But changes are made off-camera. He only displays knowledge of how to use a micrometer to verify the threads. It's OK to say I don't know, but I think a lot of us are assuming a lot of calls were made to support while the camera was off. I would respect him more if he bought 2 or 3 $1000 machines to learn on, then stepped up his equipment as his skills increased. Everyone can relate to that. I really didn't learn anything from this video. The question everyone is asking themselves is how is this new shop going to make money beyond hats and T-shirts. As the king of Siam said " In my head are many facts Of which I wish I was more certain, I was sure, Is a puzzlement"!
chatter: how you turn it, the cutting forces tend to lift the carrier away from the bed. is it possible to turn the other way around (turning the tools by 180°, reversing the spindle), so the cutting forces are pointing on the bed? it might give the stability, when the carrier ist pressed against the bed's prism and surface. thank you for your videos! great!
I’m surprised you don’t have thread mics . Learning G-code can seem like an impossible feat after machining manually for years but you’re getting there brother . Keep up the great work!
Happy new year Adam. the last part turned out very nicely. Certainly already an improvement over the first few tries. One recommendation: Try to get used to using a tool for roughing and and 2nd tool for finishing, even on small batches like these.
Conversational may not provide that option. That's where Adam's at at the moment. Modifying the G-Code generated (to insert the tool change) is a little way up the learning curve. Maybe a couple of days more of self-paced training and making chips.
take lighter cuts for the finish passes with the threading tool, take more cuts, add coolant, the took rub will cause chatter. i just went through this with my lathe. with grooving tool, use a z back and forth walk in, so oscillating the z on the way in. all lessons my lathe has taught me
To reduce the chatter, move the material closer to the chuck. For the groove tool, reduce your RPM and increase feed rate. In your programming, face your part first, then turn and then chamfer last.
@@dennisnicholls6267 He can't take constructive suggestions and feedback. He almost always takes it as criticism. Instead of listening to his audience he just blocks it out.
Yup, I noticed that too. I guess rather than respond to the many comments Adam has decided to just ignore it and hope it goes away. Bad move. Respect lost there Adam.
Just out of curiosity, but why is a thread relief necessary on a CNC cut thread? Not being a smart ass, just curious. I was under the impression that the thread relief zone was added in manual machining applications to give the operator a zone that wouldn't be inconsistent at the trailing end of a cut.
It provides a fixed flat shoulder for a nut to actually stop against, rather than just binding on the vanishing final thread possibly damaging the nut's thread, jamming, or just not stopping at the desired fixed point. It's good practice, and in some applications a necessary feature.
@@advil000 There is no thread relief provided on rolled threads or threads created with a die... They work fine. Im pretty sure that thread relief is only necessary on manually turned threads.
A tip we use in our machine shop, after you run your threads come back with your OD turning tool for a skim over the top of the threads then run the last pass of the threading tool again. Leaves amazing threads with no need to file by hand.

I really like the use of the pig mat on your table to protect the surface and keep 'stuff' from rolling or skittering off a flat surface.

please use the wear fields in the tool offset table for the tool correction offsets. When you change the tool length youre in grave danger of crashing your machine if you mistype. Thats what the wear fields are for.

I'd say maybe the cuts are a bit aggressive for the set up? And yes as some others have mentioned, a spring pass can be added in to de-bur the thread. But that is the learning process and I think you are smashing it with the cnc learning curve so keep pushing 🤛
Happy newyear, Adam N Abby. I wish you good health and continued success in the new year :)
Great to see you testing yourself and the equipment. Happy New Year Adam and Abby to you and your family all the best for 2023
Interesting thread measurement tool, I don’t remember them or they were not though of when I was a young apprentice. First time I’ve seen them. I learned on the old 3 wire and still have them 25 years later.
@17:38 Use a full profile Insert , that insert will Top off the threads Major Dimension too , you won't have burr, Or if I don't have one generally I make a finish pass followed by a thread repass not efficient but I get clean threads , the Tooling representative will surely have a solution too
Your doing great, hang in there man.
Lots of good insights in the comments here. Since I know nothing this helps me learn too. 🙂
You saying "you know nothing" is kinda hillarious :D
@@StefanGotteswinter Well I didn't specify but I meant about CNC machine operations. lol Otherwise I do know a lot about a little and a little about a lot. 🙂
Those CMC$ will be a godsend when you need to batch out a lot of identical parts. That will let you work on other projects while the mind numbing process of making the same small part over and over and over it’s done by the CNC. Awesome
Great job, I noticed your screwcutting tool was still taking a big cut on last pass, you need a spring pass, a CNC machine like this with an insert like that will make mirror finish threads with no burrs.
Topping inserts are the only way to not have burrs unless you do a finish turning pass after the threading. You can run the finish pass backwards and it will debur the thread on the chamfer.
I am glad you said the radius cut isnt needed.
Looks great Adam, I'm sure the CNC machine will make things go a lot quicker for you. Hope you had a good Christmas holiday, and wishing you and Abby all the very best in 2023. Thank you for sharing all the great video content you provide for us on RUclips. Always appreciate the tips and tricks you mention for the machinists out there. Cheers and Blessings 👍🙏.
Thanks for sharing and Happy New Year to you and Ms. Abby.
Will we get to see some of the conversational programming vids on the new machines?
How would the use or absence of coolant effect the final surface finish and chatter of a part like this?
Hi, I have noticed that 250rmp makes less tool deflection and have more control on it. Full profile insert on threads is my recommendation for better results without filing afterwards 💪 I have in siemens control and there is cycle for thread relief, easy to make with vnmg tool👌 Keep on training and there it comes that same confidence that you have with manual machines💫
Adam, talk to Milltronics about how their lathes are setup. When you change a tool geometry offset by 0.001" that will likely be a radial change. Some controls have options for making the wear offsets radial or diametric. I've got my lathes set up in diametric but your one thou change may have moved two thou just because it is a diametric change, not a radial change.
Agree. The ML22 I use at work is setup for radial adjustment in the offsets but I'm thinking it can be changed to diametric as well.
He had a Milltronics guy there for training on the machine. Wear offsets are as basic as it comes and surely would have been part of that 'training'.
@@richardjones7249 Adam is drinking from a firehose right now and this is a simple thing to miss or forget during (or since) training. I have been running my specific machines here for a few years and still constantly have questions for the applications guys. I'm just trying to help him the best I can because he taught me how to run a lathe for free on the internet and now I am actually in a position to potentially give back.
At around 2:54 make note of what diameter is on the display. 3:01 pause program-measure-make that adjustment here then rest should be gnats ass without the scrap. Gimme more Milltronics content!!!
10:20 Perhaps do a .010" cleanup cut on the OD of your material before starting to cut threats, to ensure the overall final diameter.? 11:25 aha fine minds think alike you did it.! Happy next year
Happy New Year, and thanks for all the videos in 2022! ⭐🙂👍
I could see how that cnc makes quick work of those threads, one you have it perfected. Happy New Year!
I went back and rewatched the video to see if I missed something. He said he was going to figure out how to program the job using "conversational". Next, he has the metal rod in the machine, but no programming. Later we see a screen with numbers already filled in for a program file "Shaft Threaded End" with no explanation as to how he got there. There is chattering which could be reduced or eliminated with maybe more and lighter passes. It would have been enlightening to follow through with that thought. But changes are made off-camera. He only displays knowledge of how to use a micrometer to verify the threads. It's OK to say I don't know, but I think a lot of us are assuming a lot of calls were made to support while the camera was off. I would respect him more if he bought 2 or 3 $1000 machines to learn on, then stepped up his equipment as his skills increased. Everyone can relate to that. I really didn't learn anything from this video. The question everyone is asking themselves is how is this new shop going to make money beyond hats and T-shirts. As the king of Siam said " In my head are many facts
Of which I wish I was more certain, I was sure,
Is a puzzlement"!
chatter:
how you turn it, the cutting forces tend to lift the carrier away from the bed.
is it possible to turn the other way around (turning the tools by 180°, reversing the spindle), so the cutting forces are pointing on the bed? it might give the stability, when the carrier ist pressed against the bed's prism and surface.
thank you for your videos! great!
need right handed tools for that
I’m surprised you don’t have thread mics .
Learning G-code can seem like an impossible feat after machining manually for years but you’re getting there brother . Keep up the great work!
Happy new year Adam and abbey to u and your family have a great day, love the videos.
Happy new year Adam.
the last part turned out very nicely. Certainly already an improvement over the first few tries.
One recommendation: Try to get used to using a tool for roughing and and 2nd tool for finishing, even on small batches like these.
Conversational may not provide that option. That's where Adam's at at the moment.
Modifying the G-Code generated (to insert the tool change) is a little way up the learning curve. Maybe a couple of days more of self-paced training and making chips.
take lighter cuts for the finish passes with the threading tool, take more cuts, add coolant, the took rub will cause chatter. i just went through this with my lathe. with grooving tool, use a z back and forth walk in, so oscillating the z on the way in. all lessons my lathe has taught me
HAPPY NEW YEAR TO YOU AND ABEY
Happy New Year from Berri, South Australia.
Happy new year to you and your wife
To reduce the chatter, move the material closer to the chuck. For the groove tool, reduce your RPM and increase feed rate.
In your programming, face your part first, then turn and then chamfer last.
Comments are now turned off on the Sump Shark Video! I wonder what that means? Maybe someone reads the comments after all?
@@dennisnicholls6267 He can't take constructive suggestions and feedback. He almost always takes it as criticism. Instead of listening to his audience he just blocks it out.
Yup, I noticed that too. I guess rather than respond to the many comments Adam has decided to just ignore it and hope it goes away. Bad move. Respect lost there Adam.
@@Slugsie1 Anyone watch the 'Bad Chad' channel?; Adam might just come out with a 'Perspective' video.
Interesting indeed.
Hilarious! All my fault...
Great work Adam, fun little project to learn from.
Thanks for sharing.
Great stuff Adam. Was thinking the other day that the only way to get good at any skill is to practice, practice, and more practice.
Wao
The machinist turn to be a programmer.
Them machine it’s fast .
Those are good to repeat jobs .
I still love the manual lathe .
No computer .
Just out of curiosity, but why is a thread relief necessary on a CNC cut thread? Not being a smart ass, just curious. I was under the impression that the thread relief zone was added in manual machining applications to give the operator a zone that wouldn't be inconsistent at the trailing end of a cut.
It provides a fixed flat shoulder for a nut to actually stop against, rather than just binding on the vanishing final thread possibly damaging the nut's thread, jamming, or just not stopping at the desired fixed point. It's good practice, and in some applications a necessary feature.
@@advil000 There is no thread relief provided on rolled threads or threads created with a die... They work fine. Im pretty sure that thread relief is only necessary on manually turned threads.
