<p>An abrading tool uses oscillatory motion to achieve abrading, such as for polishing or grinding operations. The abrading tool has a spindle (25) capable of mounting an abrading pad (28). A motor of the tool has an output shaft (13) and a cam unit (17) on the output shaft (13) which is partially received in a cam follower (23) mounted on the spindle (25) produces the oscillating motion. A self-aligning bearing (18) interconnects the cam unit (17) and cam follower (23) to reduce vibration and noise. The tool has a pneumatic motor and exhaust air from the motor is used to aspirate dust generated by the tool in operation. <IMAGE></p> |
