PURPOSE:To efficiently perform dressing and grinding by providing a grindstone at the end of a swaying arm and arranging a dresser and a work on the track of the swaying arm end so that components of a grinding board are reduced in number and structure of said board is simplified. CONSTITUTION:A swaying bench 6 is provided on a base board 1 through a shaft 5, and a grindstone bench 12 holding a grindstone 17 is installed on the head of the swaying bench 6. Further a dresser 29 and a work 37 are arranged on a track of the grindstone 17 at the front of the base board 1. A rotary cam 42 provided on the base board 1 can guide a cam follower 40 on the swaying bench 6 by energizing means 44 such as cylinders installed between said base board 1 and the swaying bench 6 or the like. Through swaying of the swaying bench 6 by positive rotation of the rotary cam 42, dressing of the grindstone 17 and grinding of the work 37 are performed by means of the dresser 29 and the grindstone 17 respectively. |
