Joint cutting device has cutting unit that is pivoted oscillatory for producing working motion by motion device around virtual axis of rotation within angle range, where motion device is arranged distantly from virtual axis of rotation

摘要

The joint cutting device has a drive for generating a drive moment, a cutting unit (1) with a curved cutting surface (4). A motion device is provided with a transmission device for transferring the drive motion from the drive on the cutting element. The cutting unit is pivoted oscillatory for producing a working motion by the motion device around a virtual axis of rotation (9) within an angle range. The motion device is arranged distantly from the virtual axis of rotation.
