MACHINING METHOD OF TOOL FOR MOLDING COMPONENT, AND TOOL FOR MOLDING COMPONENT MANUFACTURED USING THE MACHINING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a machining method of a tool for molding a component capable of mass producing accurate tools for molding the component without shortening service life of a cutting tool even when a machined material is made of cemented carbide. SOLUTION: The inner peripheral surface of a prepared hole 41 between an escape hole 41b and a hole 41c for molding a collar that are machined in the machined material 41 is ground by a grinding part 71a of a glitter 71 to machine a center hole 41d, the inner peripheral surface of the center hole 41d in the machined material 41 is cut by an edge part 72a of a Compax cutter 72 to machine a step hole 41e.
