Abstract

Construction of the instrument for lapping of the balls between coaxially installed lower drive disk and two rings (internal and external) is described. The internal ring is connected with rotary drive and provided with a conical bevel. The external ring is immovable and provided with ring groove for the balls disposition. During the processing the balls are moved along the ring path formed by four surfaces of the instrument having different velocities. Significant increase of the ball sliding velocity relative to the instrument allows to decrease the contact load on the balls and increase quality of the balls surface. Continuous position change of the instantaneous axis of the balls rotation provides high quality of the processing. Results of experimental investigations of the lapping process applied to the balls made of the hard-magnetic sintered material KC37 are presented.
