I am looking forward to this build. I am most curious in the 160k rpm spindle the only thing that I know of that goes that fast is a dentist drill
Rock n Roll
Build in 'Cartesian Style CNC' published by rob4cnc, Nov 27, 2018.
The Rock n Roll is built on granite, is solid as a rock, and gathers no moss. This build provides a high degree of accuracy and repeatability. Built to be strong, use redundancy, and use long lever arms to average out imperfections in the equipment. Built to go fast and light. We will use a high speed spindle, large high voltage stepper motors and small cutting heads to overwhelm the forces produced at the cutting head.
