Cryogenic machining?

Post by sraney » Mon Oct 05, 2015 3:12 am

I spotted this last week on the Applied Science YouTube channel and thought It might be amusing to someone here. I've been looking for a way to cut some multi layer shapes out of neoprene, but I think the shope might get a little nervous if I started super-cooling the mill. Anyone here up to see if they can pull it off using a Shapeoko?

Oh, well, jeez, yeah, that was much simpler than molding a rubber part! :D

Pretty cool... oh, wait, puns. When you say "negative 80C alcohol" it sounds more worrying about cold burns than when working with liquid nitrogen. But I'm guessing this guy has enough experience with stuff like that that it's reasonable for him.

This isn't the first time I've heard about freezing rubber to mill it, but using dry ice and alcohol is new to me. Definitely a lot safer than liquid nitrogen. :D
