Not to say that there is not a skill for CNCing, yours is a brain and muscle skill. I would rather be a manual machinist in a job shop speaking for myself. Its an art form.
This video shows exacly why i love watching you do stuff Peter.you always do it the correct way and never cut corners. Always indicate raw stock and milling the center for perfect center. Never in a hurry 😁👍
Thank you Peter for posting this interesting video on your work. I'm sorry there are so many trolls with the same endless repetitive comment. I appreciated you answering the question so many times with patience.
I understand people don’t have the time to read over 200 comments. So I don’t mind answering the same question. It at least shows they are interested. Thanks John.
I couldn't help but imagine the finished product as a massive engine valve+stem, and got chills from the size of the resulting engine to go with them =D Very nice work. Thank you for the quality videos.
This part is very similar in size and shape to shafts I'm machining at the moment except we shrink fit and weld the flanges after rough turning and final machine it.I guess it comes down to what it's used for.
Just incredible work! I love your videos...even though I'll probably never have the opportunity to operate machines like yours, I very much appreciate the precision and beauty of the work you do! Thanks for posting your videos, I really enjoy watching them. All the best, Jon
Nice to see the machine moving that much material, it is a hell of a lot of chips. Just out of curiosity, it would be interesting to see if @David Wilks could come up with a way to using a parting tool then trepan the material discarding the outer portion. Then come back and rough the blank to the size you ended up with.
I had the same thought. I wonder if there are any trepanning specialists here in the U.S. In this case, Peter got the job because he can knock 4 pieces out pretty quickly and the customer knows he's getting top quality work - quickly. Time is money, as they say.
Hello Peter. Right after working for centerline I worked at Watson grinding (Right around the corner. ) we used to made very similar parts like that. You brought memories back to me.
We make a very similar shaft part like that in our shop. We get blanks with a large disk and shaft friction welded together. Thus we avoid machining all of that off of a solid billet.
Impressive material removal peter. I was thinking something along the lines of the guys with the trepanning idea, we used to have a work where we would face grove as deep as the face groove tool would go and then part it with a normal grooving tool, creating rings. We actually used the rings for the parts, would make 3 different diameter parts from the stock we had, were much smaller pieces of course :) and it was brass. Not sure you have face grooving tools that go deep enough to make it worth while in such massive stock. Here it would make the process much longer, you would have to remove the tailstock and hammer the ring off every time, probably the time waste not worth the material saving.
As a young Applications Engineer in Australia I once did some test cutting for a customer in the Japanese factory on one of these machines with a 6.0m (236") bed length. Incredibly powerful and versatile machines.
Haha. And do you think that Felix would get a broom, sweep up and move the full drums without being told. He's too busy smoking cigarettes and looking at his phone.
My grandpa use to co own a farm equipment dealership. There was a table there that I ended up with. It was made back in the 60s and the insurance made them get rid of it about 2015 so I got it. Its 2’ by 3’, 4” thick solid steel. An anvil table. I cant even imagine how much it weighs. It was sitting upside down on concrete blocks when I got it. I slid it and it destroyed those blocks.
On my Instagram I showed a 55 gal barrel. This roughing filled 4 of them to around 3/4 full. Any more in one would make them to heavy to move easily. We tried to weigh one but our scale only goes to 1000 lbs and it was more than that.
Yes I milled it with the B axis tilted at 30 degrees to make the centers 60 degree included angle. This machine is a mill/turn machine. It is a full 5axis machine. That can do both milling and turning.
Any reason why you don’t just use a large centre drill ? Was it ease of what’s in the machine ? Or was it a specific angle or something you required ? We milk some centres but only really large ones.
Great video, what are the they are going to be used in? They look like really heavy duty drive shafts for a chipper/shredder machine or something like that.
I asked the customer if I could make videos on this. They said yes as long as I don’t tell who it is for or what it does. So that will have to remain a mystery.
That is a baby chuck heck even my 36" 4 jaw is small compared to some out there but you certainly won't be dual key setting my chuck unless you have 8 foot arms. LOL
This is an example of when forging could save a lot of machining time and stock. Of course, you'd need a large-enough run to justify the tooling for forging.
Exactly what I was thinking. How many parts would it take to justify having castings made for this job. 1,000lbs of chips is insane but if its only a small order, you have no choice
@@squeegied3rdeye713 Casting one-offs is a bit easier than forging, as nowadays you can actually produce your pattern with styrofoam or 3D printing rather than wood like the older way, but there's still the fact that casting isn't always foolproof. I worked few a few months for a company that machined iron castings for engine flywheels, and one part had a recurring issue with voids near the hub. Casting steel is more difficult than grey or ductile iron, from what I understand. But I've seen some neat videos of a company near me that forges similar parts for things like gear blanks, but those are done a few dozen at a time.
Yes but this steel doesn't have a real high carbon content. OK for hammers and tools. But it should be higher for knifes. It would work maybe combined with something of higher carbon.
This is the SMW hydraulic steady rest. Normally it opens up. But I’m right at the max capacity. 16.18” dia. Of the rough stock. So I have to manually shove the arms out a little.
Watching just a few of your videos I have learned a great deal! I am completely new to CNC machining, so please forgive my ignorance. Is there no way to use trepanning to remove the bulk of that material? I don't know how one would deal with the big "tube" of excess material coming off when parting it, maybe that's the reason it isn't done. It just seems like such a waste to create half a ton of chips when making a shaft. Thanks very much for your excellent videos and discussions.
Look at David Wilks latest video he is doing a similar thing. It is possible on the right machine. On my machine I don’t really have the proper way to mount a treepanning tool or the volume of coolant necessary to make it work. It would be nice to have the piece of hole bar that would come from it.
@@EdgePrecision I found your site after watching David Wilks. I understand about the tool and coolant. Trepanning sure takes a torrent of coolant to cool the tool and move the chips. I hadn't thought about that. I appreciate your taking the time to respond. Thanks a lot.
I'm thinking if the stock was 3D printed, there will be less waste due to machining but I'm not sure if the strength is comparable but the price would be bit higher.
I wonder if an enormous core drill (a bit like the concrete ones) and a super-sketchy parting operation could let you keep most of that removed stock in one piece. Probably not worth it but would still be interesting.
Non-cnc hobby machinist here. Whats the advantage of using a drill and endmill at an angle to cut a center vs just using a center drill in this instance?
I have a question please. What are the reason why you don’t prepare two smaller pieces, weld them together and finish them off? That would probably save you a ton of material, time, tooltip, and other... Must these pieces for some reason be made out of one solid piece? Please advise.
This is the way the original parts were made and failed. So this customer felt that in order to eliminate the possibility of that happening again, they wanted a part from solid. Also their machine was down and this was the fastest way to do it.
@@EdgePrecision thanks a lot for your swift response! Yes, I thought so myself, but a proper laid weld (x-rayed without voids) should in theory be just as strong as a solid piece. Perhaps the welding wasn’t up to the mark? Anyway, thanks for sharing your work👍😁
@@SuperAWaC Billet metal is a solid length (often in a square or circle profile) of material that has been extruded into shape, either by continuous casting or hot rolling. Billet material is often used in cnc machining.
@@darrennelson6803 I am a machinist. That is not a billet, it is a bar. Billets are what get made into bars. Using billet in the manner you are is a nonsensical marketing buzzword.

Hi Peter, after 3 hours of heavy cutting, how was the temp of things? I see you checking at 9:35. If the coolant kept it room temp, did the coolant heat up? I'd think 1000 pounds of blue chips had to heat something up.... Thanks for the vid!
Would it be possible to make the flange and the shaft seperate parts? Say you machine the shaft from some smaller od stock, then machine the flange and weld them together or thread them together somehow It would take more processes but would waste far less metal and money, possibly even time
In general practice, all machine shops recycle all scrap just to get rid of the swarf. And it may seem wasteful to you to rip a part like this straight from a bar, but, if you only need a few parts, its way, WAY faster to start from a raw shape and just get things finished. If the customer wants it fast, not cheap, then you machine the shape they want and hand it back to them fast. If they've got a million-dollar a day factory sitting idle waiting for this part, they really don't care how 'wasteful' it is to get the part faster.
@@gnatlywings9088 1st, thanx for the word swarf, i didn't know what the proper term of art was. 2nd, thanx for your explanation. it makes a lot of sense.
@@EdgePrecision I think you could try even 8015P grade for better tool life, since no interrupted cut involved. Mine experience shows that 8015P grade is more like older 820P, and 8025P is like older 830P. In low SFM applications also the new 5015S can outperform the standard steel P grades. Please try AC5015S or the AC5025S on the Inco vs AC6030M. I really wish i was yours SUMITOMO technical sale support guy. Great job as always Peter!
I very seldom get this circumstance. Most of the jobs I do take a lot of manual operation intervention. I did have to stop and index the insert quite a few time during this so there wasn’t a hour straight without doing anything.
I am overwhelmed by your professionalism. I would be happy if you address the questions: what makes the Mazak so accurate? stepper? Linear encoder? Rotary? Routes on linear bearings? I would love a lesson on the subject.
This machine is just servos with encoders to ball screws. The ball screws have liquid cooling run thru them. And yes the axis run on linear bearings. To get a better idea I have a video that shows these things.
@@EdgePrecision surprised that it hasn't moved, leaving a good envelope all around should do it, awesome content, that center drill was on another level. always a joy to watch,
This is why I advocate machines having their own jib cranes instead of trying to save money with a communal lift or having just one bridge or gantry crane. Jib cranes save so much time and effort
If the machine can handle a part or fixture weighing more than say 60-100 pounds it should have a hoist. It is also a mistake to put a 1000 lb hoist in a machine that can handle 4000 lb. put the correct size or someone will overload it!
You can't always store the parts in close proximity to the machine. So, if you have to transfer the part one or more times in order to machine it you gain nothing. Normally a jib crane has a very short distance it can travel.
Why do they turn it all the way starting from the initial od? Like why couldnt they cut down the desired od (plus an inch or two) with a hollow core bit or some sort and then cut the stock into two main pieces? I feel like that couldn’t be that difficult and would increase the value of the scrap greatly
For this few parts the cost of doing that would exceed the value of the scrap. Also the time it would take to make or acquire the tooling to do it would be to long. One other and even more important issue is there is no way on this machine for me to even do that kind of machining operation. There is no way to properly mount and support the treepanning tool. So for this customer who was in need of the parts on a shorter time schedule. This is the most economical way to go. If there were more parts and time a open die forging would be the way. This would use less steel and also require less machining roughing time.
There is high pressure coolant. But in this video I wasn’t using it. Otherwise you wouldn’t be able to see anything. This is just the normal thru the spindle flood coolant.
I have said it before but despite my 20+ years working in manual machine shops with a little CNC programming, these videos make me feel like a newbie.
Ive been machining for 15 years in a small shop and also feel like a newb watching these . Machines i run are much older snd smaller .

No heat treat.

I just didn't have one setup but I had these tools already in the tool changer. Either way would have worked.
I get that. Sometimes it’s fast and easier to just use what’s already set up.
What is the reason u turned ur B axis at such an angle when rough turning or is that just to make clearance?
Yes this provides more clearance from the chuck jaws from the milling spindles face.
Is it peeled and polished bar stock? With a bit of surface rust on it
No it appears to have just been rough turned.
I love that you can create your own center point rather than using a lathe center drill. Seems to be so much more satisfying.

I guess it gets the cutting speed up without spinning tons of metal at 2,000 rpm.
It's always better
Good to see you back again, yes quite a few bins of swarf, could the part not be a forging ??
It would be kind of expensive for only 4 pieces.
You know Peter, with your Forging Area you could take chips from some of these different projects and do a Damascus Knife.
Yes but this steel doesn't have a real high carbon content. OK for hammers and tools. But it should be higher for knifes. It would work maybe combined with something of higher carbon.

If not it seems really wasteful not to start with a piece of stock closet to the final shape.
In general practice, all machine shops recycle all scrap just to get rid of the swarf. And it may seem wasteful to you to rip a part like this straight from a bar, but, if you only need a few parts, its way, WAY faster to start from a raw shape and just get things finished. If the customer wants it fast, not cheap, then you machine the shape they want and hand it back to them fast. If they've got a million-dollar a day factory sitting idle waiting for this part, they really don't care how 'wasteful' it is to get the part faster.
@@gnatlywings9088 1st, thanx for the word swarf, i didn't know what the proper term of art was.
2nd, thanx for your explanation. it makes a lot of sense.
What type of insert did u use for the heavy roughing?
A Sumitomo cnmg 432 grade 8025.
@@EdgePrecision I think you could try even 8015P grade for better tool life, since no interrupted cut involved. Mine experience shows that 8015P grade is more like older 820P, and 8025P is like older 830P. In low SFM applications also the new 5015S can outperform the standard steel P grades. Please try AC5015S or the AC5025S on the Inco vs AC6030M. I really wish i was yours SUMITOMO technical sale support guy. Great job as always Peter!
Nice to have a job like this every day where you can sit back for an hour or two an let the machine work.
I very seldom get this circumstance. Most of the jobs I do take a lot of manual operation intervention. I did have to stop and index the insert quite a few time during this so there wasn’t a hour straight without doing anything.
I am overwhelmed by your professionalism. I would be happy if you address the questions: what makes the Mazak so accurate? stepper? Linear encoder? Rotary? Routes on linear bearings? I would love a lesson on the subject.
This machine is just servos with encoders to ball screws. The ball screws have liquid cooling run thru them. And yes the axis run on linear bearings. To get a better idea I have a video that shows these things.
Look at the video “Under the covers of the Mazak”.
Thanks !
Que trabalho maravilhoso
I’m wondering what was used to make a cut on something like that
ленточная пила
@@werd469 well no shit
wondering how much it will warp and bend due to stress? any stress relief procedure?
That’s why I’m roughing it first. Although it doesn’t appear to have moved. But it won’t matter the way I’m going to finish machine.
@@EdgePrecision surprised that it hasn't moved, leaving a good envelope all around should do it, awesome content, that center drill was on another level. always a joy to watch,
Nice machine
It would be interesting to see the fit of the centre inside the machine centre hole. Cross section view.

This is why I advocate machines having their own jib cranes instead of trying to save money with a communal lift or having just one bridge or gantry crane. Jib cranes save so much time and effort
If the machine can handle a part or fixture weighing more than say 60-100 pounds it should have a hoist. It is also a mistake to put a 1000 lb hoist in a machine that can handle 4000 lb. put the correct size or someone will overload it!
@@EdgePrecision I visit lots of shops with a bunch of bent engine hoists sitting around
You can't always store the parts in close proximity to the machine. So, if you have to transfer the part one or more times in order to machine it you gain nothing. Normally a jib crane has a very short distance it can travel.
@@garys9694 that's why you put the parts on a pallet and then move them around with a pallet jack or forklift.
@@SuperAWaC Yeah, I know, that's what I said.
Why do they turn it all the way starting from the initial od? Like why couldnt they cut down the desired od (plus an inch or two) with a hollow core bit or some sort and then cut the stock into two main pieces? I feel like that couldn’t be that difficult and would increase the value of the scrap greatly
For this few parts the cost of doing that would exceed the value of the scrap. Also the time it would take to make or acquire the tooling to do it would be to long. One other and even more important issue is there is no way on this machine for me to even do that kind of machining operation. There is no way to properly mount and support the treepanning tool. So for this customer who was in need of the parts on a shorter time schedule. This is the most economical way to go. If there were more parts and time a open die forging would be the way. This would use less steel and also require less machining roughing time.
@@EdgePrecision Awesome that makes sense, thanks for the reply. Cool video!
Hello. Make more videos with big parts like this plz.
hey Peter any experience with CAMate?
Nope. Sorry.
Wow what was the sfm on that? Looks like it's really moving!
I see it now didn't watch far enough.
It’s in the video. 600 sfm. Most of the video is speed up.
Peter is that high pressure coolant ? On this machine ? Good video 🌸🌸
There is high pressure coolant. But in this video I wasn’t using it. Otherwise you wouldn’t be able to see anything. This is just the normal thru the spindle flood coolant.
