とを特徴とする樹脂層加工用ブローチ装置。[Claims for Utility Model Registration] It has a cutting edge that is approximately the same as the target outer circumferential dimension of a workpiece having a resin layer formed on its cylindrical outer circumferential surface parallel to the center line. In a broaching device equipped with a full-form broach that cuts the resin layer by relatively moving in a direction parallel to a center line, the outer circumferential dimension of the resin layer before the cutting process is larger than the target outer circumferential dimension. a sub-forming broach having a cutting edge of smaller dimensions; the sub-forming broach, together with said forming broach or separately, in a direction opposite to the cutting direction of said forming broach; A broach for processing a resin layer, characterized in that an actuator is provided to move the broach from the end of the machining end side to the middle part, so that cutting is performed by the sub-form broach prior to cutting by the general-form broach. Device.
