I was wondering if anyone knew some speeds, feeds, chip load, etc for milling Peek.
We are making spinal implants from Peek Optima and we are not allowed to use any liquid coolant of any kind. We are currently using a cold air gun to minimize burning of the material which is also not allowed. Currently we are having most of our issue with a 3/32" carbide endmill milling a pocket with a tolerance of +/-.001". Any help would be better than nothing since this our first experience machining Peek dry.
