Kind Code:
A1
Abstract:
A grinder holder (4) of an grinding tool (1) comprises: a shank (6); a mounting part (21) whereon a grinder (3) is mounted; a movement mechanism (22) that is equipped with a motor (35) and causes the mounting part (21) to move in the axial direction (X) of the shank (6); a load detector (23) that detects a load acting on the grinder (3) mounted on the mounting part (21); and a control unit (52) that drives and controls the motor (35). The control unit (52) monitors the output from the load detector (23) and successively calculates the amount of change in the load, and drives the motor (35) on the basis of the load and the amount of change, thereby performing a projection control operation in which the grinder (3) mounted on the mounting part (21) is made to advance or retreat.
