Machinists

Makino makes very informative presentations

Madlad I say. Crazy.

Hyper-specialized machines to drive those cycles times down.

That 'ring' cutter is crazy mad. https://youtu.be/xPxpuna-GuM?t=278

I love the statement because it's true but in context it's rather absurd...

context: Elon calls for crazy tight standard tolerance of 10 micron (±.0002") because if everything is perfect then the assembly will be perfect...

"All parts for this vehicle, whether internal or from suppliers, need to be designed and built to sub 10 micron accuracy.​"

It's significantly easier hitting that tolerance on small parts... Try making the same lego that's bigger than a hand and you'll be going home tail tucked.

And I can't wait for the cost burden to skyrocket. Perfectly functional parts being thrown part for small dimensional imperfections. Entire cars being scrapped because thermal expansion wasn't accounted during manufacturing/assembly. And the opportunities for malicious compliance... oh jolly...

It looks like operators pointing sensors at the shoe instead of the part, pressing go and walking away.

Thankfully they have a bunch of spares drill bits...

In this two part video, I do a metalizing metal spray repair on a pinion shaft that belongs to Tom Lipton of Ox Tool Co. The shaft is out of a newly acquired Roll-In band saw that he is repairing, and this shaft is very expensive to replace. It has some wear along where it rides inside of some bronze bushings, so I use the metalizing technique to bring life back to this old shaft. In this one, I show setting the shaft up, masking, undercutting, and then the actual spray welding. \added card links to some of my older videos containing spray welding. It's worth a peek for all of my newer subscribers that havn't watch any of my older videos.

"So the rotary fixture plate is done, right? WRONG. I’ve got just one more feature to add to it. A set of material squaring guides. I have an idea for a dovetail clamp that allows for adjustability, but is also self-squaring. I’ve never seen anything quite like it which could either be a good thing or a bad thing. It’s one of those weird things where the mechanism makes sense, but at the same time… doesn’t. So let’s find out, and build a functional prototype!"

It's very informative material in a digestible format and pacing.

Anything new these days have proprietary names and it's super frustrating tying to find comparisons between modern high performance endmill for crappy materials.

AlTiSiN, I hear is the new good stuff but every brand that seems to carry them obfuscate it like harvey's "tPlus" or Fullerton's "FC-20", SGS's Ti-Namite-M. So you don't really know what you're buying.

Then there's AlCrN. How good is that vs the other coatings?

What kinds of weird and wacky coatings have you found great success in your crappy materials?
