PURPOSE:To provide a controller for carrying out cutting and processing of a material to be cut by maintaining high mechanical efficiency of a motor driving type cutting machine. CONSTITUTION:A controller of an emery saw 10 as a motor driving type cutting machine is provided with an ammeter 32 for detecting actual current value of a grinding wheel motor 18 changed by the velocity of sending an emery grinding wheel 16 at the time of cutting and processing, a calculation circuit 40 for controlling the velocity of sending the emery grinding wheel 16, and the actual current value obtained by the ammeter 32 and a rated current value of the grinding wheel motor 18 preliminarily set are compared with one another by the calculation circuit 40, and a command signal is output for feedback- controlling the velocity of sending the emery grinding wheel 16 so that the actual current value is identical with the rated current value. |
