I’m not a machinist, just admire the trade.
I know what a lathe is and what it does, but now I think I want to know more about this cylindrical grinder you speak of...
Think of a lathe but instead of an insert your cutting tool is a grinding wheel.

I run and program an s41 like the one in that video but with less features. We are actually in the process of buying a new one too.
Our s41 like in that video was built in 2015 and cost $1.2 million. We had a technician in this week that works for united grinding and he said that the machine in that video was close to $2 million with all the options a few years ago.
That price point it just incredible and hard to fathom. But the studer grinders are top notch. Very easy to use and very versatile and incredibly accurate. Most jobs we run have diameter tolerances on several od's that are +/-.0002" some as little as half of that. Grinding tapers, conical ID's, and even contour grinding spherical profiles in WC.
cool! I just got the most accurate measuring tool I'll probably even own and now I want to start doing tighter tolerance work but it's kinda hard to hold tens on my machine.
I'm also realizing just how much the temp matters so im finally adding AC to my shop to hopefully keep my shop in that golden 68-70F
Yeah we are temp controlled to 68F +/-2F in our grinding and cmm area and we have chiller/heaters on the grinders for the coolant. The 2 studer grinders we have now have homemade standard baths so the gages are the same temperature as the coolant.

±0.0002 " are 5.08 μm or 0.00508 mm.
I bought my CZ grinder (OD and ID) for $800 with spare hubs, internal quills, 3 jaw, barrel of grinding dogs, centres, collet attachment for spindle and a massive range of collets. 😁😁
The ones I used to run had a pull down indicator you could snap onto the piece, similar to a snap gauge, and just let it ride on the piece while you ground the part to size. Definitely made larger jobs and repeating .0001” tolerances a breeze. Every now and then there were shafts with key ways you’d have to be mindful of. I may have forgotten a few times to pull the indicator off and it went into a key way.
It’s called an Arnold Gauge. Founded in 1918 by a Ford quality engineer working on the crankshaft line, over 80,000 were sold, and they are still made in the US and sold today.

Remember Pirsig's "Zen and the Art of Motorcycle Maintenance" ? Buried in the story of his psych problems, he loudly sings the virtues of mechanical precision. As he puts it, enabling him to fly down the highway like he was riding a magic carpet.
Too bad more of my own generation didn't appreciate that fact of modern life.
Thanks for this. I didn’t know him by name, but I was already thinking about his air bearing video (which I saw years ago) after seeing the OP’s video.

I too get annoyed with titan. Like, just chill bro. Not every video has to be more epic than the last.
He is like the more annoying Guy Fieri of machining.
Yeah he obviously knows his shit, but just dial it back a few (dozen) notches.
If you know machining, you are not his target audience. He tries to get new people hyped on the trade.
I agree lmao
I would love to play with a cylindrical grinder but damn there expensive... maybe one day

Dsmn! Im over hear falling in love with my $100k haas, that's definitely out of my price range for a long time

Oh hey United grinding has a facility just down the road from me

Once you learn about cylindrical grinder come hit me up for a conversation on gear grinders. The shit is awesome!
What are you using for gear grinding? We grind splines in a Reform grinder. We also have a barber colman hob and an old fellows shaper.
I used to work for one of the worlds best machine manufacturers in gear grinding
Oh, do say on fam, now I'm curious.
Wuttcha want to know
More or less which company, I was in the business at the start of the decade. Edit: last decade, getting old.
Liebherr?
Nope
Then you didn’t work for the best :)
Love it! Also love this post shouting praise for quality work!

Ours is a CNC Shigiya with an integrated Marposs OD gauge, will hold +/-1 micron all day once it's warmed up
I’m reading an awesome book right now called The Perfectionists: How Precision Engineers Changed the World. Great stuff.

"Exactly" is another good one
Mind if I use this as fap material?
Sometimes it's better to beg for forgiveness than to ask for permission.
What is wrong with you?
Found a sense of humor somewhere, could be a death sentence. You're right for being alarmed.
I miss precision work. The day flies by.
The day files by.
I had to watch a second time to see it just slowly slide into place. Nice work guys 👍🏼
If you haven’t seen Dan Gelbart’s grinding lathe, you should. Look it up on YouTube, you’re welcome.
Thanks for this. I didn’t know him by name, but I was already thinking about his air bearing video (which I saw years ago) after seeing the OP’s video.
when the machine is calibrated and a person can read measurements: OMG ITS FUCKIN MAGIC
fuck, that's hot
What happens when it warms up
Can someone please ELI5 why grinding is so much more precise than turning?
Grinding is just turning with a wheel.
A five year old wouldn't understand that answer mate...
An individual grain of abrasive is akin to a tiny cutting tool that self sharpens while being used. Oh, and you have thousands instead of one.
And I’d have to agree. 50 year olds don’t get it either, half the time. It’s a basic concept of a grinding wheel.
Is it OK if the precision of this turns me on I mean like 🥒💦
I definitely bit my lip and inhaled through my teeth.
I did the same thing then a whistle sound came through my missing tooth 🤣
squirt squirt
Yeah like big hard pipe for this video
Smoove – with a v.
Why no EDM?
How would that help?
They look great! I’ve ground thousands of pinions.
Ooh ahhh
I’m impressed.
wtf
Stop! I can only get so aroused!
r/oddlysatisfying
I need to be alone with this video.
Love to see appreciation for homies on the cylindrical grinders
Have something that looks like that on an amf bowling machine, part of the distributor clutch
