PURPOSE:To improve lapping and grinding acuracy by making it possible to put light stuff carrier in use in such a way that the light stuff work carrier is tensioned on the periphery of the carrier by tension device and that the carrier is reciprocated by cam means. CONSTITUTION:Work 2 to be lapped is carried on the work 3, and the outer periphery of work carrier 3 is tensioned by tension means 4. Since the light stuff carrier 3 is reciprocated in fore-and-aft, and left-and-rignt directions eccentically by means of cams 5 and 6, both surfaces of work 2 are simultaneously lapped or whet polihed by lapping machine or whetstones 1 which are disposed on upper and lower sides of the light stuff carrier 3. According to such arrangement, the light stuff 2 carried by the work carrier 3 is lapped or whet finished in a high accuracy. |
