Device for the treatment/working of surfaces
First Claim
1. A motor driven handheld tool for the machining of surfaces, comprising:
- a first housing unit for supporting said motor driven handheld tool;
a second housing unit joined to said first housing unit, said first and second housing units being rotatable relative to each other;
at least one tool holding fixture that is rotatably mounted in said second housing unit and that is adapted to receive a tool therein to allow a surface to be machined;
a means for driving said at least one tool holding fixture and for driving the second housing unit for rotation relative to the first housing unit;
wherein said driving means comprises a joint rotary power source that drives said at least one tool holding fixture at the same time as it causes relative rotation between said first and second housing units; and
wherein said driving means further comprises a drive component joined in each case secured against rotation with the end section of a drive shaft of said at least one tool holding fixture at the opposite side thereof and frictionally or interlockingly coupled with the first housing unit for transferring torque to said first housing unit for the rotation of the same relative to said second housing unit.

Abstract
A device for the machining of surfaces comprises a first housing unit (1), at which the device is to be supported, and a second housing unit (2), in which at least one tool holding fixture (9) for the grinding tool respectively polishing tool is rotatable mounted. The first and the second housing unit (1, 2) are joined with one another relatively rotatable to each other. Furthermore the device comprises a driving unit to drive the at least one tool holding fixture (9) and to drive the second housing unit (2) for rotation relative to the first housing unit (1). As a result of the superposition of the rotation of the individual tool holding fixtures with the rotation of the housing units, in which the tool holding fixtures are mounted, arise a better and faster machining result, a good superposition of the grinding marks and thus a symmetrical grinding pattern.
