PROBLEM TO BE SOLVED: To shorten the time required for moving a work to a next machining position to restart machining, by preventing a partitioning plate from interfering with a thickness detecting means, without causing the thickness detecting means of non-contact type to escape during rotation of a turntable having the partitioning plate. SOLUTION: When machining a work 1, a shutter 64 of a lower side partitioning plate 60 on a turntable 16 is positioned at a partitioning position, so that the lower side partitioning plate 60 partitions a plurality of machining positions on the turntable 16. When the turntable 16 is rotated and the work 1 is moved, the shutter 64 of the lower side partitioning plate 60 is positioned at an open position, so that a thickness detecting means 40 passes a tolerable space 63a where the shutter 64 is opened, to thereby cause no interference. By opening the shutter 64 provided on the lower side partitioning plate 60 instead of escaping the thickness detecting means 40, the time required for moving the work 1 is shortened.
