PURPOSE:To automate regulation of motor force for driving a cutter by constituting such that the handle shaft for feeding a cutter such as a drill is program controlled specifically by microcomputer through a motor and an encoder. CONSTITUTION:A motor and an encoder are fixed to the handle shaft for feediing. The microcomputor is programed to achieve such feeding as the force is regulated optimally when threading by means of a dies, and the inverter is controlled in accordance to said program to regulate the force of A.C. motor for driving the feeding handle. With such arrangement, regulation of force of motor for driving the cutter is automated. |
