You can hear the difference in the ringing, especially with the rubber and the magnets. The ringing is lower pitched and dies off much quicker. Good demonstration. I’ll try it the next time I have that problem.

[@birikiuc7092]

With the magnets you change the resonance frequency of the part. Rubbers and magnets works like a dynamic damper. Very good video.👍

Peter,. This was great. I followed what you did with the steady in the last one and thenshowing another way is superb. I had not ran an automated steady only manual ones on cnc. Your stuff is solid.

32:03 I definitely hear a big difference! There's much less resonance with the high density rubber pads/stud/joint connector arrangement. I would also think that it's absolutely worth taking the time to do whatever you can to dampen resonances and vibrations from your parts, if your after the best surface finishes possible.👊👍

Great tutorial on indicating and setting up. I do hope though that when you finish turned those spindles you dressed the center in the end so it was concentric again. I mean it isn't needed but it sure is nice for the next guy.

[@EdgePrecision]

The center gets machined away when the 1.0" hole gets drilled. Than c-bored to 1.25 diameter with a chamfer the center can run in.

[@Tezza120]

The toolchange only working at horizontal and a specific clock is probably so if if the machine is about to do a automatic tool change and something went wrong, it won't drop the tool. Nice work on these parts

[@iltubal]

Peter, putting a 1.50" dia fixed post(bolted -secure) and mchined in place(same height} could serve as support and consistent 'shoulder' for the flange to bump into. This may also speed up squaring the flange , setting the Z-axis work offset only once and possibly serve as the anti vibration too. Just a thought but I am a really an avid follower and so thankful for your sharing here. Maybe a similar sleeve at the end of the shaft will help arrest whipping of the part inside the spindle bore..? God bless you.

[@kevndo]

I made a comment on your last video and asked if it was the stress that was throwing it out of round.. I have to apologize . I didn’t realize that the end in the check was a saw cut end.

[@Evolvescalate]

Cool ideas for the resonance dampening with he rubbers and magnets. I think Haas lathes have a feature built in to do automatically what you said about the playing with the speed manually. When we used to turn long and thin parts (much smaller diameters of course, something like 1/4 inch or so) we would sometimes hold them by hand with a stick or a piece of plastic, following the tool to prevent the chatter, not something very safe and i don't recommend doing that of course :)

[@EdgePrecision]

Yes I have done the stick thing myself. But on this machine it won’t run with the doors open. You are correct Haas has a feature that varies the speed/feed to damp vibration. This machine is to old for stuff like that. I wish it had it.

[@dinosauralan.9486]

I personally find your videos really fascinating and in some way relaxing (No doubt just the opposite to you, re relaxing.) My machining experience and knowledge has really been added to/too/two by enjoying your work or should it be an ART form? The largest component I have recently turned was originally a 23mm in dia. billet of dialuminium required, for a small `crowned` pulley for a friends belt sander tool. But the principals are just the same whatever diameter the component being. Basics are basics and if one does not understand them, well?? A `thou is a Thou` whatever the size of the component, clearance is constant.. Take care. Thank again.

[@RambozoClown]

Thanks for showing the skim cut method for the steady rest. I guess you would also have to recut the center in the end to keep everything true?

If I was going to use it, yes. But in this case I drilled and bored a concentric hole with a chamfer.

Excellent, as always! Just for my personal understanding of machining in the US: What pricing range (ballpark) and lead time are we talking for 3 pcs of this part? Im also a small business owner (electrical engineering, mostly for construction equipment) and Im astonished that you find time to spare, for making these great videos for us to enjoy. All the best from Switzerland.

[@EdgePrecision]

There were actually four parts in this order. The customer picked up the first one to check the assembly. But to answer your question without going into detail. I did the job in a total of six days (including making the videos). But because of the extreme weather and power outages here in Houston. It actually took a week longer. As to financial I only spent around $200.00!on tooling because I already had everything else. And I made around $140.00 a hour for my time. But in this case it’s a little hard to tell because of all the interruptions because of the power outages at the time. Here in Houston it is easy to acquire materials such as this. This material was delivered the next day sawed to length. Thanks hope that helps.

[@franklinblazek25]

Just a question coming from a machinist. Have you ever used a drill in the live tooling and rotated the C-axis at the same time? I’ve was told this will produce a very straight and concentric hole but have never had the opportunity to try it. Your thoughts? Thanks for the videos.

[@EdgePrecision]

I have never done this but the principle is sound. Back in my gun manufacturing days. The man that drilled and riffled our barrel blanks. He made precision match riffle blanks. He drilled them by rotating the drill and the blank at the same time.

Good info Peter. I'm curious that you don't machine deburr your holes and other details at times. It's something I've taken to doing in the last couple years.

[@EdgePrecision]

On this few parts it takes more time to program, set up and prove out the operations. Also there is always the chance of a mistake just to save a few minutes of deburr time. When your dealing with a lot of parts or inexpensive material. Than OK, but it just isn’t worth it to me.

[@CorndogBrownie]

I think one of things that people also need to understand, is large parts like these also release stress as they are machined. Especially when the cross sectional area drops significantly. Plus, usually the harder the material, the more it takes off while machining. I work with ALOT of thinner stainless parts (316), but they are from 16-22 Ø, and after even minor amount of material removal, they need to be left to cool to room temp and on especially long parts, left overnight for stresses to work their way out Awesome video, still wish i had the Mazak. haha Stay safe, Peace

[@billdlv]

Good job Peter, very clear explanation. I'm wondering why you did not make some soft jaws considering you had several parts to machine?

[@EdgePrecision]

I wanted to indicate the back of the flange to make sure. Not just depend on the jaws. You saw how it changes when I adjusted the jaws. Just to be sure. Also I already had the jaws. A set of soft jaws for this chuck costs around $300.00. Not a insignificant sum.

[@vishrutvora2465]

@@EdgePrecision that's quite a big amount! Must be some good alloy.

[@zouabimarwen4829]

Great job !! Ref to order these magnets ?

[@ThePaoligno90]

I think I get why the magnets help. It's not because they are magnets (that helps because they stick without help). It's because the way you position them, by hand, it's not exactly symmetrical, so they prevent resonances from lasting longer. You basically create destructive interference between the sound waves in the metal and they quickly die out.

Everything is OK now. We had our power out for two days in the coldest weather. That froze and burst two of the pipe in my house and caused some water damage. I have shown a few posts on Instagram. After the power sort of came back on there was rolling power outages. On for 4-6 hours off for 4-6 hours for the rest of the week last week. It started around Saturday night and finished on Friday a almost a full week. Some people who had variable rate plans got hit with enormous bills. like in the $14,000 range. I'm not sure how that works. I think the governor is trying to get the power company's to take care of it. We shall see. It doesn't seem right when they caused the problem.

[@nikolaiownz]

You comment about the mazatrol and teach when you set your offset. i agree my old mill with m32 mazatrol is reverse - when you teach an offset you tell it where THE OFFSET it compared to your current location - not WHERE your tool/spindel is compared to the offset you want. I agree with you peter its the opposite way on other machines haha

[@EdgePrecision]

I think the people that made the Mazatrol were thinking from where the tool is to the part zero. They are thinking in a incremental direction. That would be positive in this case. They probably are software designers and not machinists. In our case we would think the tool is setting at minus 1.5" in Z. So if we told the control that it would place the zero accordingly. I think my little Haas lathe in the garage works opposite to this. But than when your programming in Mazatrol. Everything in Z minus is positive numbers.

How do you command the milling spindle to index a lathe tool at the B90. Position? And do you use different work offsets for the same tool? Great job BTW !

You set up two different tools with different index and clamp angles. Than all you have to do is change to the tool you want. With a M6 T#. The machine automatically indexes it at the tool change. Hope that makes sense.

[@mjshorty19]

Just curious, why no chamfer on the holes in the program? No chamfer mill in the machine already?

Because for four parts it takes more time than deburr. Also the drawing doesn’t call for them. And there is always the risk of a mistake. If you are starting with a $1500.00 piece of material. A mistake just isn’t worth it.

[@jameswood9764]

Start by machining the face saw cut and turn part of the OD then flip in chuck to help with later alignment?

[@EdgePrecision]

The reason I did it this way. I was going to chuck the first operation in the serrated hard jaws and tighten them tight so the part wouldn't move. I was only chucking on to about .750" length of this big piece of material. There wasn't a lot of stock on the bars OD. So in order not to have dents from the hard jaws serrations in the flange end. I elected to not turn the stock first.

[@slucas601]

I noticed a small offset in the Y axis offset, Is this to align then center lines of the two spindles?

Yes this machine has always been that way. This could be corrected in the parameter settings. There is a setting that’s off.

[@thomaseisen304]

Just curious ...how many different jaws you got fot all the chucks you got? Or do you make new jaws or modify old ones if you got none that fits ?

[@EdgePrecision]

One of the advantages of a manual 4-jaw chuck is the travel range of the jaws. This makes it possible to get by with fewer top jaws. Looking at my jaw shelf I would say I have less than 20 sets of jaws for this chuck, and that includes the hard jaws. I do modify old jaws if I know I will not be running the same job again. These are bib jaws that go on this chuck. A set costs between $200-300 dollars depending on the size. So I try to use the old ones first.

[@byronwatkins2565]

Why not support the piece with the steady rest or center while you loosen the chuck jaws slightly and allow the part to relax on center? Then tighten the jaws and verify that the chucked end runs true. Otherwise, I would be concerned that the perpendicular faces are no longer perpendicular to the axis.

[@EdgePrecision]

On this machine the tail center is a hydraulic quill. This can’t be extended without some force on it. If (as I showed in the video) the end of the part isn’t faced square. It will force this out of square face up against the face of the chuck jaws. And even if this seems OK with the tail center engaged in the center drill. When I retract the tail centers quill the part would deflect du to the strain of trying to be forced flat on the Un square end. I’m not exactly sure what you are referring to about un squareness of the faces? If the part is finished (with no stress du to the chuck) turned all in one setting everything will be square and perpendicular. If I did as you suggest (because of what I previously described) there would be stress introduced into the part. So when Un chucked this stress would be relieved and than things could be out of square.

[@byronwatkins2565]

@@EdgePrecision When you turned the part originally, all of the faces were perpendicular to the rotation axis. When you removed and re-installed the part, this is no longer necessarily true unless the part's center line is exactly on the machine's rotation axis. An indicator near the chuck allows you to establish one point of the part's center line on the rotation axis, but this still allows the remote end to whip around the rotation axis verifying that the faces (that are perpendicular to the center line) are not yet perpendicular to the rotation axis. Since the hydraulic center precludes using that to center the remote end, I would try to use the steady rest to center the remote end while loosening the chuck's grip momentarily. This would allow the faces to relax perpendicular to the rotation axis. An alternate approach would be to indicate the large face itself near the edge to establish that it is perpendicular to the rotation axis.

@@byronwatkins2565 the part had another .25” turned off it. It doesn’t matter if it ran true the second time it was chucked. Everything was recut as if the first time. As long as everything cleaned up. The center was reclaimed when the hole was drilled and bored on the end of the part for the tail center to run in.

What tool are you using to tighten the chucks?

[@EdgePrecision]

I use a 3/4” ratchet wrench with a short extension.

[@JosueArias-in8qg]

Do you use a specific brand ? I want to get one for work but I want it to last

[@EdgePrecision]

My wrench has Titan on it. Do a search for Titan 3/4 extendable watcher wrench. There are many they appear to be the same wrench just branded with different names.

[@TomChame]

Very interesting, thanks again.

Damn man running a nice face+ turn a chucking diameter from the start would save headaches!

[@EdgePrecision]

If you faced it and turn a clean diameter that might help with the first roughing a little. But after the part bows in roughing the face you turned would no longer be square. So if you wanted to maintain that you would have to do it again after roughing. Now That could be a process. Rough the face and OD as you say. Than turn the part around. Rough the part. Turn the part around again with the flange end toward the tail center and chuck (changing jaws) the very end of the shaft. Supporting it on the steady rest behind the flange somewhere. Re skim the face and OD still leaving stock. Than turn around again (changing jaws again) chuck the OD of the flange like I did here get the part running true. Reclaim the center drill if necessary. Than finish the rough close to finish size. Than skim for the steady rollers and machine a start hole for the drill also turning the chamfer so it all runs true (I should have done it this way in the video). Than drill and finish as I did in this video. But is that really any better? You see any initial face won’t remain square after roughing. Ask me how I’m know this. Because I tried it that way on other parts in this same order. I don’t want to be, like I won’t hear any other ideas. I tried to explain this to another commenter. That I tried it. But sometimes you all (Not meaning you but global you) sometimes are so sure in your ways you won’t listen. That I tried it already. Again I appreciate all comments and please understand I’m not picking on you in any way.

@@EdgePrecision There's always more than one ways to skin a cat. I indicate my center drills to the chucks 0. A live tool center drill could possibly be off in x or y but I'm running a conventional turret. That machine is pretty crazy! I've mainly been around fanuc and okuma controls.

سلام خیلی خیلی عالی بود متاسفانه زبان شما متوجه نمی شوم🙏💐💐

[@samuelbreland1985]

Is that machine a Makino?

[@EdgePrecision]

It’s a Mazak e650H Integrex.

[@chrisyboy666]

probably not worth it now but we centerfuse the coolant makes it last so much longer.....saves ££££

[@inuyashacoolieo]

I was here!

[@therealspixycat]

Can you adjust the face using the studs that there anyway?

[@EdgePrecision]

Yes this is a way. Look at Robrenz channel. He has modified his chuck to do just that. kzbin.info/www/bejne/jWjNi4Jpj7mXZrM

[@therealspixycat]

@@EdgePrecision Keith Fenner uses a small leaves or small crowbar to press the piece away from the chuck.

thanks for the video
