Abstract
Cutter head for accommodating multiple cutters, wherein the cutter head has a separate receptacle opening for each of the cutters, and wherein the cutter head includes clamping means for clamping the cutters in the receptacle openings. A cavity is implemented in the cutter head in the region of at least one of the receptacle openings, which is separated by a thin wall or layer from this receptacle opening, and the cavity can be filled with a fluid and a pressure can be applied thereto.
Claims15
A cutter head configured to accommodate multiple cutters, the cutter head comprising:
- at least one receptacle opening configured to receive a cutter;
- a clamping means for mechanical clamping of the cutter in the at least one receptacle opening;
- and
- a cavity in the cutter head adjacent to the at least one receptacle opening and separated therefrom by a thin wall or layer, and configured to be filled with a fluid and pressure applied thereto,
- wherein the thin wall or layer is deformable by a fluid pressure of a fluid in the cavity so as to provide for a hydraulic clamping applied directly to the cutter and independent of the clamping means.
A method comprising:
- using a cutter head that is configured to accommodate multiple cutters and has at least one receptacle opening configured to receive a cutter, a clamping means for mechanical clamping of the cutter in the at least receptacle opening, and a cavity in the cutter head adjacent to the at least one receptacle opening and separated therefrom by a thin wall or layer, wherein the cavity is configured to be filled with a fluid and pressure applied thereto, the thin wall or layer is deformable by a fluid pressure of a fluid in the cavity so as to provide for a hydraulic clamping applied directly to the cutter and independent of the clamping means, the cavity is filled with a fluid;
- and wherein the using step comprises:
- adjusting a pressure of the fluid in the cavity prior to machining a workpiece, so as to deform the thin wall by the fluid pressure of said fluid in the cavity.
