Abstract

An end mill resharpening device is provided which will resharpen the primary and secondary cutting edges of both the flutes and the end of the mill. All of the proper side and end angles, as well as an end "fish-tail" angle are produced automatically by the unique features of the device. Additional benefits provided include a novel method of making an air bearing, a floating spindle knob and grinding wheel balancer.
