PURPOSE: To decrease the number of set-up grinding machines and a relative space and save labor by grinding the ground portions of plural works with one grinding machine at the same time and continuously grinding the plural portions of one work.
CONSTITUTION: Plural work holding means 3X3Y mutually spaced apart are provided on both sides of a grinding wheel 38. In this way, the mutually-different ground portions of plural works 1 held by the work holding means 3X3Y can be ground with one grinding wheel 38 at the same time and the number of set-up grinding machines can be decreased. Also, if these work holding means 3X3Y are continuously arranged in such a manner that a plural of such grinding machines are provided in transversal line, the structure of a work feeding device D can be simplified.
