Driving device for rotating tools with superimposed oscillatory movement and tool therefore

摘要

A carrier bush (15) fits on bearings in a drive casing (11) so as to rotate. A drive shaft (13) rotates on bearings in the carrier bush. A tool mount (16A,16B) holds processing tools. A vibration-stimulating device generates vibration overlay for the tool mount. An independent claim is also included for a tool with a drive device.
