An apparatus and method are disclosed for deburring the surface of a printed circuit board passing along a moving conveyor. The apparatus comprises a rotating brush head for abrading against the first surface of the printed circuit board. A three phase wattmeter is utilized to sense the power consumption of the motor driving the rotating brush head and generate a signal in response thereto. A control circuit is connected to the three phase wattmeter and regulates the elevation of the brush head in response to the three phase power consumption of the motor.
