PURPOSE: To prevent any partial wear and tear in a grindstone from occurring by removing burrs in causing uniform abrasion in the grinding wheel as moving it in the stone full length direction of a grinding surface range from the front end to the rear end when letting the stone deburr from the work starting end to the finishing end of a compact.
CONSTITUTION: A shaft-mounted cylindrical wheel 4 is used, a constant speed of rotation centering on a self-axis and another constant speed of longitudinal vibration in the self-axial direction are caused in the wheel 4, and when the wheel moves from end to end of each edge 12 of a compact sleeve 11, grinding point dislocation control over a grinding surface range from front end to rear end is performed by horizontal surface sequence control of a robot 1 so as to have a grinding contact point with a sleeve of the wheel held toward the full length direction of the wheel, and furthermore grinding pressure in the wheel is automatically operated by rotary motion using gravity of a balance arm 9 with an adjustable weight 10 and the robot uplifts the wheel up to the contact point, while even in any grinding contact point, grinding force of the same balance weight always acts on a space between the wheel and the sleeve.
