Abstract

PURPOSE:To prevent unsymmetrical wear in a surface plate, by ranging the movement of the contact surface of a work over the whole surface of a surface plate in such a manner that an arm of a roller supporting a block is horizontally swung and the work is reciprocated in the radial directions of the surface plate. CONSTITUTION:A block 29 to which a work is secured, is set in a predetermined position of a surface plate 24, the lateral surface thereof being made contact with the lateral surfaces of supporting rollers 30, 31. The surface plate 24 rotates when a motor is started, and both blocks 29, 29' supported by the rollers 30, 31, 30', 31' also rotate so as to initiate a lapping process. When motors 43, 48 linked to an arm 26 are stated, the roller 30 rotates due to a shaft 39 rotating. Therefore, rotation of block 29 is smoothly performed without irregularity. While when a projecting pin 52 in an eccentric position is made circular movement by a motor 48, a lever 45 swings with a rotating cylinder 28 as its axis, the arm 26 swings in a predetermined range, and the block 29 reciprocates relative to the surface plate 24 in the radial directions, thereby unsymmetrical wear in the surface plate 24 can be avoided.
