How To GRIND a 16 Sided POLYGON on a Cylindrical Grinder

Chris takes O2 Hardened Tool Steel on the Studer S41 and grinds a 12 sided and 16 sided polygon into a cylindrical work piece. He gives insight to the programming of High Speed Form Grinding.

man... I love Titans. So refreshing seeing a team of pros, clean and beautiful machines and great content! Presentation is always on point. Keep it up guys!

It was a great video. Thank you for sharing your knowledge with us for free, Mr. Chris. And don't forget the wonderful staff who filmed and edited this video... You took me to another world man. Boom 💥

[Sirmellowman]

bro....that chuck is SO FREAKING he re chucked that part and it ran out literally PERFECT....wtf!

[npip]

You can always say "12-gon" and "16-gon". As in, "twelve-gon" and "sixteen-gon". Inevitably you'll have to swap to that pronunciation if you were to ever do an uncommon number or a large number of sides.

[dangabi]

you can do almost anything on this grinding machine i am working on an s33 and i once did a m40x5 thread left hand side with 2 beginings. and easy to use.

Thank you for the video. I would like to see you finish grind hard anodized aluminum part to size(+/-0.0004) OD and ID concentric and N4 finish. We quoted something like that once but didn't get the job.
Also interested to know about fixturing finished parts where you can't squeeze them in the chuck.

I want one for my desk it looks beautiful. At 7 mins the concentration on the task was obvious and the camera was forgotten. True focus on the task.. Who cares if “i cant spell it” you made it. Lovely with even the out takes, it makes you part of the team. Welcome to the world of the Academy.

Do an actual camshaft. A full camshaft build that will actually be test run in an engine.

Im from Germany. Worked on old Studer.
I used to learn not to stop the wheel during measuring.
Because the the wheel would suck in the oil and gravity would pull it down so there would be inbalance after...
It's not like that nowadays?

Had to make one of those (Icosikaitetragon 24 sides) recently for a laser scanner. Needed mirror surfaces and I have no grinder. After milling, it was had lapping over the granite with 1500 grit followed by some buffing compound on a sponge. I have serious tool envy watching this.

Ok, If you are going to attempt polygon grinding on a studer you must remember a few things. firstly look at the part Chris has ground. how flat does it look? its clearly radiused on every edge. You cannot achieve flatness using a angle approach wheel. the machine needs to know the exact wheel diameter to achieve perfect flats so you need you use a straight wheel. You cannot measure a wheel at 30 degrees ie wheel 2 as T1 and T11 are totally different sizes. I do many form grinding jobs in aerospace and the flatness is easily within 0.001mm on these amazing machines

I have been around cnc machines à lot... But machines like this... Simply incredible.

[andyvan]

love it, great show and tell, and wow, what a piece, and that surface finish.
a question, what grinding wheel did you use, as there aren't too many videos showing what is on it, and how to mount the wheels, one assumes it is done by hand?, and not an auto tool loader?

[pliashmuldba]

Well with CNC you can do just about anything, but i dont like running maskines like that, also a reason i was out of the trade for so many years.
Okay i do admit i can get almost aroused watching some machines work, and also the things for the home industry i could make with such a machine.
But my time on CNC machines are as little as 5 - 10 hours

[nickdimperio]

Could you guys grind out a gear? Is that even possible

[ramonstvol]

You ask us what form you should grind next, please grind a Capto Tool Holder so like a tapered 3 sided polygon. That would be nice to see

[leonschumann]

haven't u dressed the wheel? (btw u gotta make a factory tour video with the crazy machine park ur running)

[life.is.to.short]

Technology is getting better and better. Pretty soon don't need to go to school to learn it.. lol 😆

[Jatsekusama]

Why not make a STAMP this way out of some crazy material and then using it to press a crazy hole in something? Limit is your imagination, and we know you guys have a lot of it! :D BTW, great video, Chris you do a great job focusing on the details. Greets :)

[ShopperPlug]

Does this polygon part have real applications or was it literally for demonstration? Polygon parts like the one showed in this video are particularly used with precision lasers, such as used in laser scanners which are used for various of products like a laser printer.
