Apparatus and method for material processing

The invention relates to apparatus for material processing, in particular for tissue or bone treatment, comprising a tool head and arranged thereon tool, wherein the tool head (WK) relatively to this adjustable support member (2) has at least means of which the Werkzeugkkopf (WK) can be supported at a material machining on the surface of a material to be processed (4), wherein the position of the tool (1) is adjustable relative to a material to be processed surface at a material processing by controlled or regulated adjustment of the at least one supporting element (2) by means of an actuator in response to data which are supplied during material processing of a control / regulating unit of the at least one actuator. The invention further relates to a method for material processing, in particular for tissue or bone treatment, in which a tool head arranged thereon tool along the surface of a material to be processed is guided, with which the position of the tool (1) relative to the material to be processed surface is set at the material processing by controlled or regulated adjusting at least one of the tool head (WK) provided for the supporting element (2) by means of which the Werkzeugkkopf (WK) during material processing on the surface of the material to be worked (4) is supported, wherein the adjustment of the at least one ...
