Non ci posso credere! La data sul cnc è del 12 dicembre😮 il giorno del compleanno di mio papà Elio. Che coincidenza pazzesca! Comunque bel video e complimenti. Vi seguo con interesse. Auguri di buon anno a tutto il team🎉
Wait wait wait. . . . I run manual tool and cutter grinders, and centers are never perfectly aligned. . . How do you get the taper out on a cnc like that?
It is a CNC machine any taper that might be introduced can be overcome through the programming process. 2:50 in the manual process he didn't set an X difference, but if there was taper you would measure for it then adjust the difference for that between each X position and call it a day. The difference in a manual grind is seeing if you have taper and then adjusting the machine to remove it. That can also be done on long shafts with a follow or steady rest depending on the setup and the machine. On a full CNC just program out the taper if there is on and call it a day.
@@conrad5319no he is right, yes you should try to remove any taper from tail stock but guess what, too much pressure from a steady rest or tail stock can also introduce taper(or deflection from not enough) , and you’re always chasing your tail, in a cnc you program out taper it’s way faster, literally just insert an extra X move as you feed in Z. Taper isn’t always caused by a tail stock being off
I’m going to have to see if our older version of Studer win has that position ok button when writing pictos. If so you might have shown me something new. I’ve never actually used assisted manual mode. Always just write a picto program just because of the corrections page. Plus most times even if it’s a one off part there’s almost always more than just the one feature to be ground.
On top of that an inch is 25mm which basically means that their 0.001inch is actually 0.025mm which is very bad for grinding so I just don't get their logic here
I am not a machinist but I do watch videos from many machine shops. Why did you grind the shaft rather than put it in a lathe? I’m 64yr old and it’s too late now but I wish I trained as a machinist when I started working 46 years ago. Thanks for your time.
Surface finish. And I don't know how much he is taking of but it's hella risky to take cut 10-20 microns off with cutting tools especially if it's a 1 off, and you have no stock material to work with
The gridding process came to satisfy many project challenges. example: machining a surface that has received a hard chrome coating, or steels that have had to receive a hardness treatment. And this process also helps us to have more uniform surfaces and geometries (flatter, or rounder), with very tight tolerances and a very good finish, for projects that aim to reduce friction (like Bearings). *I had to use Google translate to help me with this answer, but I hope I answered your question.*
Thank you guys for the explanation. I’ve never machined anything in my life, I’ve just learned things from watching UA-cam videos. It makes send on what you both have said. Thanks again.
Case Hardened Shafts (60ish rockwell) are a pain to turn if you have an interrupted cut such as a keyway seen on the first diameter of this shaft, your inserts will chip fast. Also achieving consistent 10-20 RA surface finishes on seal areas on shafts is much better on a grinder than a lathe. If you get a small chip before the seal section on your insert when you slow the feed down to achieve the surface finish you will end up with chatter scrapping the part. I learned this turning some 37inch long 62 Rockwell shafts coming back from heat treat, we didn't have a grinder and were forced to turn them.
@@nicktorea4017 lol you do you man I prefer to not wallow out the center in the shaft. I've never ever had runout issues because I'm using grease with dead centers.
We machine 1000's of shafts like this every year,. You show working within a .001" tolerance however the bearing fits have an total tolerance of .0002" to .0005" on a shaft of this size. What does it take to dial the machine in so that you can quickly bring the part into tolerance even if you are doing batch sizes of 1?
I have tight tolerances also. +/- .0005 On those I'll program in a rough cut to + .002, run it, measure it, then offset to hit my tolerance. When part is done, offset +.002 then rinse and repeat
I run an s41 oil at work doing aerospace shafts out of mostly inconel. The machines are very repeatable. Leave a thou gage stop. Then run it. Quite repeatable. Run that all of the time for +- 2 tenths. For some parts we set up a movomatic. Look them up. Works great as long as you don't bump it. Assisted manual is great for one off parts for tooling or grinding jaws. If you sneak up and check your sizes it works great. You use a program for production.
With assisted manual. Set off a couple thou. Start. Feed down til you see sensitron touch. Feed til you see cleanup. Spark out how long you want to. Zero out that axis. Press start. Measure. Start again. Feed down to zero point. Feed down to take as much as you want to. Repeat as necessary. You can send to dress if needed as well. Can achieve 1 tenth as needed. Can even feed in 10 millionths if you really want to.
hey, at 2:26 you didn't show us how that wheel went on the machine, would have been nice to do it step by step, no matter how long it takes, as us beginner grinders will thank whoever shows us it, not assuming anything (remember assuming makes an ass out of you and me).
Cut x and z without losing width on cutting x when you dress. On a straight wheel you lose width. You have to do more plunges on a multi plunge adding cycle time as the wheel narrows otherwise. I run an s41 oil cutting mostly inconel at work.
I grind pumpshafts daily that fit usually is a nothing area but a lot of shops want it ground that way everything runs together for balancing purposes.
Hey Mighty Mouse, I keep hearing how great the Studer grinder is but it feels like you have a Ferrari stuck in first gear going in circles in a cud-el-sac. Why don't you run 10 pieces and show us the run time you can achieve? I should dream of having one after I watch the video not just how nice the paint job is.
I’m really not a fan of this conversational programming, I run Hurcos on conversational and they are insanely user friendly, this seems weird to me, Iv ran and programmed mazaks too but this is weird, I’m sure with some practice it would become second nature
I wondered if anyone had designed an engine based on an "Archimedes screw" and WOW! this basic design popped up. I can't find anyone who's actually tried to make this so it could be a unique challenge to someone that's as capable as you guys and would be way interesting viewing. awesome channel guys. thanks. Happy new year! ua-cam.com/video/pDqMLNKdt-8/v-deo.html
A fine, useful machine and very sympathic presented. Like it
Parabéns 👏👏. Esse mundo da usinagem é fantástica.
Love Tap doesn't hurts! ;) Good Job!
Great tips Chris🤙
Nice video Chris, let’s get grindin!

Very informative

They didnt do it
At 2:30 minutes , didn't he make sure there was no taper?

@@ronb5105 No you dont Programm ist Out... You Just adjust you tailstock

Love it! Very impressive 👌
Turing grinding videos are available but what's about Harding process??

Studer maschines were made with mm Not inch. Why is the US so strange
On top of that an inch is 25mm which basically means that their 0.001inch is actually 0.025mm which is very bad for grinding so I just don't get their logic here
For the Core control, is there a CAM software that works with it?
Awesome machine we have the older version of that one.

You don't need grease on the centers?
no way that will make it run out the center tips are tungsten carbide no need for lubrication
@@nicktorea4017 yes you will get a Hydraulic effect that can create out of roundness and floating on the dead center.
Always grease dead centers I'm sure these guys commenting have hardly any grinding experience lol
German trained qualified machinist I know what I'm talking about.

What advantage does the angled wheel serve??
More space
@@xylos7234 how so?

I miss grinding
I bet there is nothing mounted on that OD 2.08". It is just for training done.
I grind pumpshafts daily that fit usually is a nothing area but a lot of shops want it ground that way everything runs together for balancing purposes.
Do you guys think AI will take over the bulk of 3d cadcam?
