Vari-speed Drives used to spindle and feed, controlled by two quick change, eight position switches. Both set on corresponding numbers give the recommended feed rates per revolution of 0.584mm (0.023"). Vari-speed drives give slower start up revs and feed for initial cutter entry and then increasing to a higher speed and feed giving faster throughput of cylinders without chatter.
