ABSTRACT:
A rolling milling tool is constructed so that the roller, in the form of a sphere, or cylinder or cone, is supported in a hydrostatic bearing to avoid counter rollers, thereby reducing the size of such tools. The roller is held in a bearing socket or guide chamber which may provide for an axial play of the roller in the chamber. The bearing socket or guide chamber is formed in a roller head which may be itself constructed for being chucked in a tool holder, or the roller head may be received in a housing which is held in a tool holder of a machine tool, such as a lathe. Ducts connect the hydrostatic bearing to a source of fluid pressure. The tool is suitable for a smooth rolling and/or work hardening roller operation.
