PURPOSE:To remove the grinding unevenness on the surface of a work stock and to grind the work stock uniformly and beautifully by integrally linking a stepping pad and belt guide mechanism by attaching to an installation frame and forming the structure of reciprocating this frame in about the right and left direction crossed with the traveling direction of the work stock. CONSTITUTION:A crank 40 is reciprocated at the stroke of two times the eccentric amt. of an eccentric pin 39 by the driving of a driving motor 36, accordingly, an installation frame 11 is reciprocated in the right and left directions. Accordingly, an endless belt 41 is press-fitted with performing zigzag movement relatively by the composition of the right and left movement thereof and the traveling of the work stock therefor and grinding and polishing are executed on the work stock. |
