PURPOSE:To aim at structural simplification by connecting plural rotary table bodies alternately to the common power unit clamped to a machining center free of detachment and vice versa. CONSTITUTION:Each rotary table body 8 is clamped to respective pallets 7, and a work W is clamped to a disc 18 of the body 8. With one side of carriers 17, the pallet 7 on this carrier is carriered onto a clamp block 11 together with the rotary table body 8 and locked thereto. Simultaneously a coupling part 15 is automatically coupled with an output part of a power unit 9 whereby power is made transmissible, thus the work W clamped to it is machined. When machined is over, the rotary body 8 and the pallet 7 both are put back to a changer 3. Next, with movement of a table 2 on a machine, the clamp block 11 is moved to a corresponding position of another pallet 7, and this pallet 7 is mounted on the clamp block, thus it is machined likewise. Consequently, the driving part can be used in common so that a table structure becomes simplified.
