Seriously though 60 IPM is pretty darn fast for most of us. I can get that
speed on my Taig with the Gecko controller, but I backed it off to 52
(mathematical speed based on kernel speed that works really well with my PC)
and cut at 30 or less and I am thrilled with the performance.


My OmniTurn lathes will cut at 300 ipm, but few materials allow that at
4000 rpm


Hmm ... that works out to 0.075" per revolution. Perhaps
cutting machinable wax -- if it won't blow up at 4000 RPM?

Enjoy,
DoN.


Actually..Ive seen it done with cyrolac and delrin and I think...filled
nylon.

The boys were using a nice .50 half round Microcentric carbide cutter.

Wierdest thing Ive ever seen. BANG and the part was done. They claimed
that anything else..and tolerences went to **** because the parts tended
to spring. They were cutting pullies for rescue gear.

I nodded politey and backed out of the door, with my hand over my wallet
and the other one hovering above my backup......
