Several machines with linear motor have been developed for high productivity. The characteristics of these machines are high speed, high acceleration and deceleration with stable behaviors of feed. Moreover, mirror-like surface is required to add high quality on the most products. In this study high speed lapping by using the lathe with linear motor was investigated for mirror-like surface. Lapping was performed after turning with the same lathe Lapping tool consists of a lapping head, a spring and holder on the tool post to assemble the linear motor lathe. The spring is used to supply lapping pressure. Lapping slurry consists of water, PEO ( Polyethylene Oxide) and diamond grain. This slurry was supplied between a work piece and lapping head. Then, high speed lapping was performed. During the process, the lapping head temporarily left from work surface in order to catch some new grains and removed some chips. The optimum combination of both the spindle speed and the feed speed was investigated for high quality and productivity experimentally. Surface roughness and form accuracy were measured. It was concluded from the results that (1) Mirror-like surface was obtained by the high speed lapping, and (2) Optimun conditions for efficient high speed lapping was revealed experimentally.
