PURPOSE:To deburr or chamfer a burr removal surface without receiving any effect of roughness of burrs, by controlling a deburring condition so as to set it in optimum condition all the time during operation according to a variation in burr height. CONSTITUTION:A piston 22 of an air cylinder 23 is pressurized in a 42a direction, while a tool rotating motor 18 is rocked in a 42a direction, and a deburring tool 5 is made contact with a machining start end part 40 of a work 1. A displacement detecting signal SA corresponding to a displacement value of the deburring tool 5 is outputted to an operation control part 36 from a varying transformer 33 via an amplifier 35. Then, from the operation control part 36, control signals SC and SD are outputted so as to cause each rotational frequency of the tool rotating motor 18 and a drive motor 14 to become optimum revolving speeds NX and NY during operation. As a result, height of a burr 6 grows large, while the motor 18 increases its speed and the motor 14 decreases its speed the other way. And, a removal speed per unit time by the tool 5 varies according to the height of the burr, thus a removal surface is uniformly ground for removal.
