closed loop vector drive.

The new panel we are building here and will be shipped to Mexico for
us to install when completed with the motion control system.

I am not familiar with the word "skiving". Can you elaborate? Petty

Sure, after a billet of PTFE is compression molded and heat treated
they put the billet on the machine at about 225 deg.
The feed axis consists of a knife blade four feet long.They feed the
knife into the billet in inches per rev at about 8 rpm and the
material comes off to a winder in a continous sheet.
They then cut it into the desired dimensions of the finished
product.Teflon tape is one example although tey skive to .250 thick

here is a picture of the material being skived, the teeth on the
mandrel keeps it from spinning and is installed with a press.

Oh, ok. Almost like peeling veneer from a log to make plywood.
