What an amazing machine. I grind parts too. I'm using an old hybrid id/od grinder. It's much older than me and I'm old. My finish tolerances are within 0.0002 for the inside. If you saw this machine I use you would be surprised. Can't find replacement parts for it so if something breaks I basically make a new one. Myself and my father have made replacement parts for it over the years. We machine the parts from bar stock rated for heat treating. I've learned so many intricate details of how to machine before heat treating to achieve a better part after heat treating. I can just listen to my machines and know what they are doing. At full swing before heat treating I run two lathes a surface grinder and a notching mill. All manual. Unfortunately i do not have anything programable. Lol. This video was really good and my hope is to maybe discuss with you some of your strategies.
@@TITANSofCNC hell yeah... I dont run it but my buddy does..uses traditional grinding for the carbide areas. Then it uses a rotating edm wheel for the pcd cutting edges. Big fan Titan, only thing Im not a fan of is your phrase " perfect " all the time. Nothings perfect in machining, period. Boom.. Keep teaching the kids my man.
get a mag chuck and drill and tap so that you can make custom rider pads so you can indicate easier and you will eliminate the issue with the parts not sitting flush on the 3 jaw surfaces. makes for an easier setup and consistent from part to part
Scott, love to see the Studer in action up close,, are tours possible? At 68 now, wish I had took an interest in machining wright out of High School. Also love that 2019 video with the High School kids being there at Titans getting involved. Yes, to seeing more a vote from me. How are the inmates progressing at there new shop at Fulton?? Bear
Love what you guys are doing. Now that you have a machine with sub-micron accuracy, it would be cool if you got deeper into the metrology side of things after showing all the cool stuff the Studer can do. It's not as cool as watching titanium being ripped off bar stock at crazy MMR's, but it's a subject I feel a lot of machinist lack in. Even your shop floor CMM may have a hard time passing a gage R+R measuring a diameter at +/-.0001 and even harder if it has to measure roundness or cylindricity under .0002. Side note, it's RPM not RPM's... Sorry pet peeve :-)
That is very true ! I am into grinding operation business and the the main disadvantage with such a machine for me to invest into is the cost and after how long i would get return on my investment.
Just out of curiosity, why aren’t you using the rotary dresser for the od wheel as well? There are a lot more variables that you can change to achieve different performance from your grinding wheels, especially on an aluminum oxide wheel.
For this particular application, we wanted to show a variety of options moving around in the machine. The single point on the 30-degree wheel helped us dress the leading shoulder for our angle plunge. We had to take many passes at .0004 to get our shoulder depth to about .5 inches. The swing down allowed us to dress the back of the ID wheel.
I remember plain old surface grinders-Your Studer grinder brings machining by grinding to a whole new dimension! If only we had machine tools like these in the school shop high school days!
I work with a old studer. I'm here looking to fix a problem, my numbers jump too high. We dress the wheel, we do the right touch off, and does not cut how is supposed to cut base on the touch off..keeps giving me big parts..like should be 35.008...it keeps giving me parts 35.055...when UTL should be 35.016
Sir, While machining a cylindrical part with a length of 300mm, we found overcut. The reason given by the operator was power failure while part was in running condition. Is the reason valid ? If yes can you suggest remedy to it.
For some smaller ID grinding you need even higher speeds, some machines we built have spindles that can spin up to 100k rpm. Sounds like a jet engine starting when they spin up.
In an ideal world you would want a much shorter internal wheel arbor. As short as possible for finish and accuracy. But you can't always have what you need. And don't forget longer the arbor lower the wheel rpm will have to be for safety.
depends how much the part has distorted during the heat treat process. On a part this side I would leave .24mm and expect to be able to clock it within 0.005mm. I generally use a mag chuck though where possible as they're more reliable
Dependent on how much material is left on the other dimensions for 2nd operation. If you have .050” just get it within .025” and no worries it all comes down to 2nd setup where you need to indicate it in to within blueprint spec for T.I.R between dimensions. I used to have parts with 2-5 setups where all dimensions had to be true TIR to .00005”max with size usually .00005” or less. That’s where indicating parts and planning how to run it became an art in itself. Let alone holding straight,round, true and size to as tight as .000005”
@@danl.4743 It's definately way cheaper. Manufacturers have technology and tools for making thousands of it. Here you have to do CAD, CAM, and make it... There are many moreprofitable things to do with your time.
Your and your team are epic going ultra I love it! Can you do a video of buying a cnc machine for a garage shop project. I'm looking into creating fairly long build scripts and create intricate parts. Unfortunately the HAAS's at work are soley used to mill/lathe zirconium for teeth
Posted this recently: th-cam.com/video/rAvSQGLcYY4/w-d-xo.html And check out the 1100mx making parts for our table in this video towards the end th-cam.com/video/5YqvhsAogUc/w-d-xo.html
I wonder how long this machine will last, doesnt have any of his haas machines, mackino is gone, dmg is gone, wouldnt think this machine is gonna last more than a year, titan doesnt own it thats for sure.
I like this guy, keep him!
I liked him right up until he put his finger prints all over that freshly ground part!

Under .0001 accuracy across the entire part order... the stuff dreams are made of.
Those grit wheels don’t last very long sadly, currently holding .0002 with resin bond wheels, last for WEEKS doing .0002
it's amazing and as a Wire and sinker EDM guy i can't wait to see dressing with EDM module.
Walter already has it...
We’re getting a Walter also.

Loving the videos. Would love more of the behind the scenes.
I ran a Studer for many years along with other grinders, it is a good grinder with bells and whistles but older grinders work just as well

I spent a week with long from United grinding a couple years ago when we got our new Studer.
Hello my dearest new friend, thank for this video first time looking this machine, very nicee machine..fully wàtch from philippines,👇🏿👇🏿👇🏿👍🤝🤝🤝

Worked studers most my career, I’d love to try this new beast.
Unfortunately not many businesses are liking to invest in such an expensive machine

I have a problem my GC 32 won't manually dress or run. It says that it's in running and complete mode at the same time.

Good presenter! The video cuts in beginning too fast - boom - boom -= boom, towards middle of video better - keep this guy!
Now we just need you guys to get 4k resolution so we can see how nice that finish really is :-)
Sir thank you,..
Hi, how much runout do you get using this 3jaw chuck?
good question
so this is more precise than milling right?
Love that finish, awesome work
Kip up with the good work
The S41 is superb. Cool-Grind or Swiveljet could greatly improve coolant velocity and delivery with improved cycle time. Great video!
What kind of runout can a grinder like this achieve?

The fact that these parts are repeatable and to spec speaks volumes for Titan CNC’s quality control.
USA.. bebe !... beautiful God bless America
Good stuff. How often are you having to change wheels? Did you use a straight wheel then change to a tapered for the shoulder?
Easy... I use a cnc like this, with control siemens (cinumerik).
Good work guys.
Spoilt ! lol I had to grind using a manual machine, no cnc back then really
Why so much stick out on such a slender diameter spindle on the I'd grind?
That is Not a Roughing Wheel/at those speeds. Just listen to the sound changes.
What surface finish do you manage to achieve on this part ?
Who are the 12 thumbs down ? Chinese competitors ?
Hi. What is great surface finish? Ra 0.2? Ra0.8? Ra6.3? :)
Will have Travis check
For some smaller ID grinding you need even higher speeds, some machines we built have spindles that can spin up to 100k rpm. Sounds like a jet engine starting when they spin up.
Your feed rate is incredible!
Cutting speed
Is bearing race can be machined in Studer?
dress the wheel very slowly just before the end to get the best surface finish. btw that doesnt look like the best liquid for grinding..
But it's the best coolant for filming.
7000sfm =35m/s
NO. It's 78 mph.
@@danl.4743 That's "kissin' the baby" really fast.
sir i am indian. I look forward to working in your company. It is possible??🤔🤔
Under a tenth is impressive over entire part.
Are you gonna make a video explaining s41 features?
It will be quite awesome if you will, there is no detailed CNC grinder video on youtube
In an ideal world you would want a much shorter internal wheel arbor. As short as possible for finish and accuracy. But you can't always have what you need. And don't forget longer the arbor lower the wheel rpm will have to be for safety.
Great work
Is studer s41 suitable for ammuntion carbide dies?
Toolholders by Titan, just imagine ... :D
How well does a part like that have to be indicated in before you guys start cutting?
Not all features are finished in this setup. Need to maintain runout back to unground features. Also risk of non clean up if high run out
maybe a few hundredths of a millimeter would be enough, but it depends on how much stock was on the part to begin with

Titan tool holders when? 😄

Is there any way to get admission to learn about codes and operating?
How are you able to calculate work peice spindle speed and wheel spindle speed? I've been trying to fiigure this out and would love some feedback.
It’s on the wheel
Those bearings and bores better be grateful
I got an idea make your costum tool holders for the mill that would be awsome.
I wonder if it's cheaper to buy them
@@danl.4743 It's definately way cheaper. Manufacturers have technology and tools for making thousands of it. Here you have to do CAD, CAM, and make it... There are many moreprofitable things to do with your time.

What is your WOC?
We want moree
needs a written warning for leaving that key in the chuck when he walks away...
Probably not too many cheap Amazon bearings on that Studer....
Wooh
Nice Maschine!😎👍👍👍👍
