PURPOSE:To make it possible to polish horizontal surfaces and vary the amplitude of abrasives by converting the rotary motion of the main spindle of a die polishing device by means of an eccentric disk and a cam mechanism. CONSTITUTION:The upper end of a power shaft 2 is connected to the main spindle of a die polishing device. The lower end forming a square shaft if fitted to a disk 16 with a square groove. The disk 16 with the square groove is provided eccentrically in relation to the power shaft 2 and performs eccentric rotary motion. this rotary motion is transferred to a Y axis slide table 6 causing it to perform circular motion around an axis 2a and, in addition, reciprocates an X axis slide table 7 along an X axis direction binding shaft 9. A grindstone holder 12 having a grindstone 11 at the end is is fitted to the lower end of the X axis slide table 7. The eccentricity amount of the disk 16 with the square groove is adjusted by an amplitude adjusting screw 3.
