ABSTRACT:
A metal saw cutter has a first motor for rotating a workpiece to be cut and a second motor for rotating a metal saw independently of the first motor.
A control apparatus of the metal saw cutter has a detector for detecting variations in an electrical output depending on the variation of the cutting resistance acting on the metal saw during cutting, and a controller for controlling the speed of the second drive in accordance with the detection signal from the detector.
