<p>The drive (10) has a housing (12) with a gear box head (14), and a drive shaft (32) rotatably driven at a longitudinal axis (34) and linked with a tool spindle (16). Eccentric cam coupling mechanisms (44a, 44b) are interconnected to the drive shaft and the tool spindle. The drive shaft cooperates with eccentric cam portions (40a, 40b). The eccentric cam couple mechanisms are formed to drive the tool spindle for periodically driving a tool (18) e.g. grinding disk, at a spindle axis (22) back and forth during direction-controlled deflection in a pivoted manner.</p> |
