Programming & Grinding Alumina Ceramic on the STUDER S41 from United Grinding.

[@MillTurn4Life]

I love the theatrical chuck key removal for the complainers in the other grinding video. Well played sir 👏

[@scottleoncini9341]

😉

[@TITANSofCNC]

Yep… 😂😂😂😂 Love how you remember that. Also my favorite part😉 Also, Scott has an Awesome sense of humor😂 Titan

[@ianagos4276]

Definitely seems like something Scott would do…

[@Stasiek_Zabojca]

When was it? Can't find it in video. Must have missed that.

This chap is a natural teacher, more please 👍

[@baconlube]

Scott is so awesome at teaching.

[@jimstantinople]

Me, an inexperienced machinist: I'll name the program the part number so I don't lose the file Scott: I named it pinky because it's pink

[@kolby4078]

don't forget the revision and date

[@astakimi]

Scott, you are a great teacher. It's a pleasure to see videos where you are the instructor.

[@davegill8634]

Legend Scott , Amazing tutorial ,Amazing Machine Shop .

[@nickscott4756]

More grinding, please! There is so little ceramic machining across YT, I would greatly appreciate more content and lessons on AlO, tool/wheel wear dressing, speeds/feeds, machines that can actually tolerate such material/wear/swarf.. Just about everything I've seen in my ceramic machine shop is point-blank " Not intended for ceramic machining".

[@origCarpeChaos]

I work in ceramics machining. I haven't seen many other channels covering cnc ceramics grinding.

[@rolandoperez6612]

This dude was my instructor at workshops for warriors. Edit: Crazy to see him on the same videos I used to watch before class lol

[@andyvan5692]

nice video, showing a few more basics than most channels, but would be a nice idea to show us how the wheels get mounted, as well as the mounting of the parts, esp. what options are out there, and why one works better than the rest.

[@extradimension7356]

This is a really excellent video and explanation - thanks for sharing and making this (close ups on the machine wheel and setup are really helpful). Seemed like a really nerve wracking part and not a lot of room for mistakes but came out lovely in the end. Amazing.

[@DannyDDeMaio]

Alumina is a really soft material (its hardness also depends on whith what technology it has been projected with) , easy to grind but to achieve low roughness it requires additional operations. Another problem with this material is that you have to make sure to dry it very well and as soon as possible because otherwise the refrigerant will leave stains. It is also important to handle it as cleanly as possible, any stain will be very difficult to remove...

[@FrozenHaxor]

Yeah it's like a sponge, any dirty grease stain and it's in there forever.

[@r3dshed]

Great teaching style in this series, keep em coming!

[@christopherdupre8978]

Do you use the blasogrind coolant with just diamond and cbn wheels or do you have aluminum oxide o.d. wheels that you use aswell? I setup and run a studer s33 and our company is afraid to change to oil vs our current coolant which is mecagreen due to only using aluminum oxide wheels.

[@scottleoncini9341]

Blasogrind GTC 10. We use aluminum oxide as well.

[@Patta159753]

I was working on Walter Helitronic 8 years as programmer, 3 years on both Blohm and Studer S33, do you have job for me? :D I love United Grinding machines :) Great work guys, nice video. Thanks. Patrik.

[@j.bin_genex1927]

amazing progress

[@Profabdesigns]

That sure looks like Beryllium and maybe some other stuff that Hi-Temp Aero part are made of. Great Video!

[@superdupergrover9857]

I love how the blank is the exact same color as the alumina MIG welding torch cups. Probably because the raw alumina comes from the same production line!

[@ricardo-iw9sq]

when you are dealing in microns why are you using a 3 jaw chuck, on our old centre grinders for accurate work holding we always use a four jaw chuck, im not complaining but just curious 👍

[@rolandtamaccio3285]

,,, maybe it's an adjustable 3 jaw that can be brought in as close as 4 jaw independent .

[@extradimension7356]

I was thinking the same thing like 5 jaw or something for consistent work holding - seemed like a really nerve wracking part that came out really well , so that was nice to see.

[@gamemeister27]

It's probably a really good, really accurate 3 jaw, plus it's a demo part

[@zeitgeist2720]

He explained it at the beginning of the video

[@ricardo-iw9sq]

@@zeitgeist2720 yes but that was about using a drive dog and grinding between centers, I just don't think a 3 jaw is precision accurate when grinding is being talked about, I might be wrong so wasn't looking at telling them how to suck eggs just curious.

[@andyvan5692]

at 2:05 could you use a collet like on a hardinge lathe?, that should hold tight on the solid surface?

[@1000crazypeople]

You guys do this and I'm complaining about grinding 50 hardened D2 plates within a half thou total tolerance

[@Awfultyming]

Had never heard of a q value before but it's easy to understand that it's an MRR. Thanks for the video. Still waiting to see you spoil the wire on that edm tho....

[@krzysztofcieszkowski6694]

Bison chuck?

[@DonStinger]

Is the chuck a type of buck chuck to set the runout? I don‘t think that the repeatability of the chuck itself is good enogh. Could you show this in a future video?

[@lilliadler1842]

Good morning I just got a new job and I will be working with machines like this.. May I know some of the challenges I will have to take note of please ?

[@jordanparkinson4584]

Do you get any wear issues on the spring loaded dead center?

[@scottleoncini9341]

Nope. It’s tipped with carbide and we run a coolant line directly on it.

[@jordanparkinson4584]

@@scottleoncini9341 makes sense didn't realise It was 1)carbide tipped b) through center coolant ! (That's trick!) Cheers!

Is that part of a roller bearing?

Can we try to guess what feisty nuclear bomb this thing is going in? 😂 jk jk, love the vid and all your other vids, just funny anytime it’s secret part made of some crazy material of super high quality made secret for the military… always makes me go “oooh so that’s probably going into some crazy spy satellite lol”

[@hinz1]

Meanwhile in China: So this is how you make that part for the new ICBM, lets order a Studer S41 ;-D

[@brandons9138]

I know you are joking, but just for information sake machine tool import and export is closely watched. The machines at my shop have sensors in them to will render the machine non functional if moved and not reactivated with the proper codes. We had to have a service guy come in and reactivate a machine after the floor crew bumped it with a cleaning machine. At one shop we were having a new horizontal mill installed when a guy joked about making missile parts. The guys who were installing the machine literally drop their tools and refused to finish until the had clearance from the machine tool manufacturer.

[@thomassmith3530]

That stuff cuts like butter if you got the right wheel. He needs a better wheel.

[@AntToeKneeo]

What grade is the wheel?

[@BIGOS-CNC]

[@moshanmoshan6148]

Hi

[@DolezalPetr]

hmmm what a strange part

[@Galli1905]

the weird singing sounds of the x-axis at 10:20 should be checked by your studer technician...some parameters are to stiff and maybe check the oil pressure on this hydrostatic axis, could safe u some money in the future....it should never sound like that!

[@beachboardfan9544]

I'm still unsure of what this is for?

[@brandons9138]

Sometimes that is the name of the game. I've made tons of cool looking parts that I have no idea what they are used for. I can make educated guesses based on who I made the parts for, but the actual end use is mostly a mystery.

[@sleddarcheddar]

That is one damn expensive part. And even more expensive machine. Jeez

[@noumanarif946]

Why grinding and not turning? I am a rookie.

[@salamdrik]

aha military rail gun part for electric discharge

[@abcqer555]

Hmmmm what strange material

[@FrozenHaxor]

Not really, very common. All TIG cups are made from it.
