Re: [CAD_CAM_EDM_DRO] Re: Lathe CNC retrofit

Hi Ballendo:
Thank you for your input.
These are very shallow tapers; 1/4 degree, 0.005" in 1", etc etc.
I need to be competitive in surface quality to cylindrical grinding.
I'm trying to cut down on formgrinding and on polishing.
Sounds like servos all right!!
Cheers

Marcus
