As always, thank you very much for all the trouble to film all of this; even with ideal camera support it's a lot of clambering around. Never mind the editing, and the actual job itself!
Thanks Jim's videos! It does take getting the camera into some difficult positions. Stopping the machine and rerunning things to get the different clips. Keeping in mind the sequence. Also you have to remember your position and the position of things in the view. So as not to make it obvious you took different shots of the same scene. Sometimes I mess up a little on that. But with some editing I can hide some of it.

@Edge Precision I really love the visual format that you employ here (without sound/ narration / talking) for first 24 minutes as it forces you to use your visual side of the brain uninterrupted ~ Which is GOOD for machining and related processes. So you really want to vicariously observe and learn. Thanks for having the balls to do that , I think your video/ visual communication skills continue to improve in leaps and bounds, thanks for making the effort and desire to raise your game in every way. + beautiful work !
What a privilege to be able to watch your videos. Sixty years ago when I wanted to learn about how manufacturing was actually done it was very rare that a person who was not employed in a shop could have a chance to watch on the shop floor what was going on. Yes, there were good trade and tech schools, but to actually get in a shop and learn by watching a person with your experience and skills work was not so easy. Many thanks!
Hi Peter, thank you for the last video Neck Down sharing your shop built and how tool grinder collet chuck we thought somehow we had missed being familiar with a tool, we liked it for the clearance and today we enjoyed the tool carousel and changer life of a holder ride along. That machine holds a lot of holders so for these two guys that have to change these holders buy hand, even on our mini TAIG CNC mill, we marvel at that ability. Yes we got to this point as well. Nice gun drill guide set up in the end. Lance & Patrick.
I saw your dilemma in an earlier video and made a comment about drilling the hole before pocketing. I should have known and was confident that there was a reason to your madness. Nice videos.
Great work. I will be telling the apprentices at work to watch your channel. I thought your work flow and toolpathing was great. And well presented. Nice to see someone do such a nice job on a fixture too. It really doesn't take much longer.

Awesome part to do a video. some sort of valve body. Dos'nt mater I guess, could be for cracking walnut's. Dos'nt look like the Ti part yet That balancing act is just another intresting part to this complicated part. In your first video couple weeks ago you explained this operation pretty well. the minutia of the drill guide and all is the story. Its the kinda story you tell real well too. so thanks I look forward to the rest of it thanks... love the shot's of the tool changer
Peter the Beaver.....Just like them you are always improving. nice work as we all wait to see. Back in my apprentice days I made drilling blocks for several long run jobs from en8 with hardened bushes. A bit like you guide but not a tied up.

Something like a KM63tser32210m for an er32 setup. Which would give you another 2.25(ish) of clearance. They make longer ones but it is harder to find the numbers for them. You can also use the colleted drill extensions in a standard tool. Er32 collets are availble up to 20mm. C 20mm shank does not deflect much under "typical" conditions.
We always just got a longer tool holder to account for head clearance. Since the tool holders are 2 inch diameter(roughly) they do not deflect. We replace a lot of the longer drills that we were using just for this type of clearance issues. Shorter drills are much cheaper and they last longer because you are not dealing with the deflection issue.
Thanks bcbloc02. Yes a Kant Twist probably would have worked. But clamping to the radius of the stock? Also I don't like that arrangement on a rotating spindle. Not that it would happen but if the spindle was turned on the clamp could fly off.
Hi Peter, the first comment after being watching your video for years. I am also working on some oil & gas parts like what you have, even the same customer as Baker Hughes. For this part I thick you don't need to machine out the pocket first, just tilt the spindle to mill the flat surface for entrance of the gun drill in the pocket, maybe it can be a bit of straight forward. But anyway, very much like the way of making fixture. Bravo!
I tried that (I thought I explained that at the end of the video. Maybe I wasn't clear enough) Because of the underlying intersecting hole close to the surface, of the same diameter this method is giving me problems and misdirecting the drill.
I might buy myself a micromotor one of these days, probably one of the newer Pferd ones. I was pricing one recently and I was surprised how affordable they were compared to the NSK ones, considering the specifications and the fact that they are German made.
Sorry if this is a dumb question but I’m a fairly new hobby machinist and I’ve been wondering what are the benefits of a horizontal mill as opposed to a normal vertical mill? Any feedback would be greatly appreciated! Thanks! P.S. Love the channel 👍
In general it would being able to machine more than one side of the part in the same setup. Depending on the fixturing multi-able parts at the same time with the rotary axis. Also the shavings fall away from the machine work. Especially if you are machining pockets the coolant flushes out the shavings better than on a vertical mill. As you see in this video it’s much easer to square up parts on a horizontal mill.
At the first shop where I worked they never used rigid tapping...they always ran the taps very slow and used a floating tap head, even though the machines were more than capable of doing rigid tapping...
@Edge Precision @30:00 Hey what's that mini chuck that you are using on your tailstock that looks super super super useful ! Can you explain a bit more about that ? TIA. [Can you explain (one day ) everything you can press a tailstock into in terms of different types of work holding ? ].
The chuck is mounted on the live center. The live center on this machine is large. It has a #6 morse taper and is 2.500 in diameter for about 4" of length. Outside of the tailstock spindle. Than the 60 deg taper starts. I made the aluminum mount for this 6.4" Dia. set-true chuck. It has a very close fit on the 2.500" OD of the Tail Center. Than a clamp similar to a Bridgeports quill clamp has. So I just turn down the pressure on the tailstock's quill and extend it till step in the jaws bottoms on the parts face and tighten the chuck. Than I can adjust the runout with the Set-true feature on the chuck. I have to use this on this part because there is no place to put a center. There is a hole in the face but its off center. There is no material there for a center.
@@EdgePrecision That's amazing I'm going to have to draw that all out to figure out exactly what you mean. I always feel a tailstock can or could do more especially as you say for work pieces that are not between centers. That's a terrific work around. Thanks !

Making such video is even harder . How many times you have stopped the job and changed the camera position to make us understand what you are doing . You are so patient MAN👍 . Thank You
Thanks Alireza Behnodfar! Quite a few times and rerunning tool changes. This is all done with just one camera at a time. No mutable camera shots. You have to put some thought into the sequence.
Great video, thanks for taking the time to share your knowledge. Your universal vise stop is interesting to me, as I made one recently. The clamp for the actual stop bar appears to have two through holes with a blank inserted. What is the purpose of this? Two different sizes of stop bar?
It is the pivot point for the clamp. The clamping mechanism doesn't pinch the rod like some types use. It clamps down on it.This allows it to move more freely when the clamp is released. It also clamps the stop rod very securely. Although if the pivot pin were removed another stop rod could be put in its place.
Love the content as always, thank you, a question if I may.... during a program with multiple tool changes, does the control automaticity look ahead and pre load the next tool into the changer or is there a specific gcode that is added by the cam software? I ask as it appeared the was delay during the tool change when switching from the roughing mill to the ball nose whilst the radius was being machined into the clamps.
You call the next tool in the program at the tool change. So if the cycle time for the current tool is longer than the tool magazine takes to get the next tool in the arm. Than there will be no delay in the tool change. As far as the video goes I was running the machine with the optional stop button on. This will make the machine stop at every M01 in the program. I put a M01 at the end of every tool. So the machine stops before the tool change. Just in case I want to check something or watch the next tool run in. I probably delayed some in pushing cycle start for the ball mill. When running a proven setup and program you would release/disable the optional stop button and the machine will run through without stopping.
Hi Peter, Just a thought. I've seen the video where you say don't work for the money, but how do you even come close to costing a job like this? Obviously you don't want to lose money. My mind boggles. Love your work man. best wishes Mal.
Was always curious, why does the B axis on your horizontal rotate a few degrees whenever it does a tool change? I've see you rotate after an OP to check the part, but it seems to happen when it changes tools
I have it in the post processor to unclamp rotate 10 degrees plus the B position than back to the B position than clamp. It does this at every tool change or B move. It always approaches the B target position from the same direction. This isn't strictly necessary but if I jog the B axis for some reason, say to look at something it will always go back to the correct position. Or if I rerun a tool or start the program in a different location. Also it is more precise to approach the position from the same direction in terms of backlash. At the big diameters or distances that things are from the center of rotation on a horizontal mill this can make a difference. I theory the axis is backlash compensated in the control so this shouldn't be necessary. But I do it anyway.
Awesome video as always. Just curious, why don't you program chamfers in, instead of doing the deburr by hand. Easy consistent chamfers was one of my favorite things when I started learning CNC.
Nice solution! I just wonder: Since you didn't forsee this problem: Have you priced it anyway as "Misc tooling issues" because from experience you know you'll have X amount of issues in such a part ? Don't know how many parts you're making but if it's in the tens that could eat into the profits maybe ?
On these kind of jobs you must expect to have some problems. The price of parts like this takes that into account. If you don't have problems so much the better. But that is rare. It is easier for me to make money on a job because I have very little overhead. I'm not paying for equipment (Its all paid for) or someone else's labor. So even if it takes a little longer I still make the same amount. I just may be making less per hour but like I said that's for me. It would be different if I was paying someone 30-40 dollars a hour.
This is Starrett ground O1 steel flat stock. I use this material so I start with something already squared up and precise in size. It also can be heat treated if necessary. I'm not going to in this case though.
That ball nose got me thinking. How to figure the step over amount between the size of the ball nose and the radius it's cutting and getting a mirror finish. Ahh! Math is hard sometimes lol.
In the cam software you can either specify a constant step over or what the call a cusp height. The cusp height is the difference between the peaks and valleys the radius of the tool leaves. Than the software calculates the step over. This is nice because if there are a lot of deference’s in inclination of the shape it will vary the step height to maintain a constant finish. The step height has to be smaller on a more horizontal angle and can be greater on a more vertical angle.
Your imagination and creativity never cease to amaze me. Great solution!!!
Thanks for the behind-the-scenes shots.
The work you do would be mind blowing even if you were working in aluminum, but the fact that you are doing this with some of the most difficult materials... is amazing.

Awesome video as always. Just curious, why don't you program chamfers in, instead of doing the deburr by hand. Easy consistent chamfers was one of my favorite things when I started learning CNC.
It takes to much time to program and set up the tools compared to just deburring for so few parts.
Boy, a lot of work for one hole! Hopefully you have more than one of those parts to make!
So far I have nine of them and there may be more.
@@EdgePrecision 600$ for the first hole?
The sounds in the opening remind me of the game _Unreal_ from 1998.
Nice solution! I just wonder: Since you didn't forsee this problem: Have you priced it anyway as "Misc tooling issues" because from experience you know you'll have X amount of issues in such a part ? Don't know how many parts you're making but if it's in the tens that could eat into the profits maybe ?
On these kind of jobs you must expect to have some problems. The price of parts like this takes that into account. If you don't have problems so much the better. But that is rare. It is easier for me to make money on a job because I have very little overhead. I'm not paying for equipment (Its all paid for) or someone else's labor. So even if it takes a little longer I still make the same amount. I just may be making less per hour but like I said that's for me. It would be different if I was paying someone 30-40 dollars a hour.
Very nice sir
Can't seem to learn enough from you Peter. Amazing content. Curious what grade of steel you use for your one off tooling like this?
This is Starrett ground O1 steel flat stock. I use this material so I start with something already squared up and precise in size. It also can be heat treated if necessary. I'm not going to in this case though.
Great vid!
That ball nose got me thinking. How to figure the step over amount between the size of the ball nose and the radius it's cutting and getting a mirror finish. Ahh! Math is hard sometimes lol.
In the cam software you can either specify a constant step over or what the call a cusp height. The cusp height is the difference between the peaks and valleys the radius of the tool leaves. Than the software calculates the step over. This is nice because if there are a lot of deference’s in inclination of the shape it will vary the step height to maintain a constant finish. The step height has to be smaller on a more horizontal angle and can be greater on a more vertical angle.
Enjoy the sound of high speed machining. Like a symphony !
