SKIVING PROCESSING DEVICE AND PROCESSING METHOD

Japanese Patent JP2017148883

A

PROBLEM TO BE SOLVED: To provide a processing device and a processing method in which a process tolerance in forming plural recesses on an inner peripheral surface of a circular hole and an outer peripheral surface of a cylindrical shape of a work-piece is high, and variable degree-of-freedom of an inter-recess pitch, an arrangement pattern and the like is high.SOLUTION: A skiving processing device for forming a recess on an inner peripheral surface of a circular hole and an outer peripheral surface of a cylindrical shape of a work-piece having the circular hole of a circular cross section has: work-piece rotating means which rotates the work-piece around a central axis of the circular hole or the cylindrical shape; tool rotating means which rotates a rotary tool having a convexed tooth tip so that a tooth tip rotation tangential direction of the rotary tool crosses a central axis direction of the inner peripheral surface of the circular hole or the outer peripheral surface of the cylindrical shape at a prescribed angle; movement control means which synchronously rotates the work-piece and the rotary tool, and relatively moves the rotary tool in the central axis direction of the circular hole or the cylindrical shape.SELECTED DRAWING: Figure 1
