Abstract

PURPOSE:To achieve a reduction of the working time and increased efficiency by providing the devices for attaching and detaching the works around a table so that a work can be attached or detached on one side of the table while another work is machined on the other side of the table. CONSTITUTION:A table 3 is rotated on a bed 2. When the three dogs 8 knock a limit switch 9 on the bed 2, the motor is caused to stop. On the table 3 are disposed work holding chucks 21a, 21b and 21c at 120 deg. intervals and a work suction air port 22 connected to a source of vacuum is formed. Around the table are placed two work attaching and detaching devices 23a and 23b in facing relation to each other. When a grindstone 18 reaches the work starting position B to begin the grinding of a work 29, a work holder 45a on the work attaching side rises while holding a work 29 by suction and the other holder 45b on the work detaching side rises and turns while holding a finished work 29 by suction.
