摘要： A work table used for effecting machining using a rotary abrasive tool. The work table comprises a table (3) for mounting a work (W) and a based (1) mounted on a table (2) of the machine. The table (3) is supported on the base (1) via a plurality of piezoelectric actuators (401) to (412). The piezoelectric actuators (401) to (412) are electrically connected to an external control unit (C). When voltage is selectively applied to desired piezoelectric actuators, the table (3) is vibrated to give vibration to the work (W). The piezoelectric actuator is composed of a laminated piezoelectric element (40), of which at least one end in the direction of expansion and contraction is fastened to the base (1).
