摘要：
A casing is rotatably and stoppably held on tool supporting means, a rotary tool spindle is rotatably supported on the casing so as to have a shifted rotary center with respect to the rotary center of the casing, power transmission means is rotatably supported on the casing, and the power transmission means and the rotary tool spindle are engaged through eccentric engagement means. The movement of the rotary tool in the Y-axis direction is performed by integrally rotating the casing and the rotary tool spindle. The machining is performed by rotating the power transmission means in the state where the casing is held stationary, thereby to rotate the rotary tool with respect to the stationary casing through the eccentric engagement means.
