Abstract

The surface treatment machine, partic. for cleaning, polishing polishing, and grinding, incorporates a motor-driven eccentric weight (4), and a tool (1) fixed to the motor housing (5) by a tool holder (8) at the weight end. The assembly forms a drive unit (3) vibrating in a housing (2). The drive unit (3) can additionally cause a suction fan, driven from the motor shaft (13) for a dust-collecting exhaust impeller. The eccentric weight rotates on the tool holder and is driven from the motor shaft via a clutch or a reduction gear train.
