ABSTRACT:
A machine tool has a rotatable brush for abrading a workpiece. The brush and a drive motor are slidably disposed on guideways for movement toward and away from the workpiece. The brush and drive motor are connected to a counterweight which is sized to have a weight less than the weight of the brush and drive motor in an amount substantially equal to the desired brushing force. A power cylinder is arranged to withdraw the brush and motor from the workpiece after a predetermined amount of brush wear.
