概要

Steel balls set into the bearings are finished with conventional ball lapping machine which uses a couple of flat and V-groove lapping plate. Conventional lapping method, however, needs so long machining time. Present study focuses on efficient lapping method using spin control lapping macine which V-groove lapping plate is separated into two parts and three plates are able to rotate independently. Spin angle θ of steel ball is rotated by force during lapping to promote finishing efficiency. Experiments show that spin angle rotation have great effect on finishing characteristics such as a stock removal, decrease of deviated diameter and surface roughness of ball. Lapping carried out at fixed angle of θ indicates that finishing modes change drastically at 45 degree, which is responsible for efficiency of machining of ball.
