機構に関するものである。[Detailed description of the invention] This invention uses electric discharge to finish the outer peripheral surface of a roll-shaped workpiece with a constant surface roughness (forming a satin-like uneven surface on the surface of the roll-shaped workpiece). The present invention relates to an electrical discharge machining apparatus for a workpiece, and particularly relates to a centering mechanism for a roll-shaped workpiece and a connection mechanism between the drive side of the roll-shaped workpiece and the roll-shaped workpiece.
以下ロール状被加工物を単にロールと略称する。Hereinafter, the roll-shaped workpiece will be simply referred to as a roll.

る。Conventionally, when finishing the surface of a steel strip rolling roll, especially a cold rolling roll, with a satin finish, it has been a method to project hard metal particles such as shot or grid onto the polished roll surface to make impressions on the roll surface. However, in recent years, attempts have been made to perform this type of machining by electrical discharge machining.

放電させることにより、被加工物表面を加工する方法で
ある。As is well known, electrical discharge machining involves interposing an insulating liquid, such as kerosene, in a narrow machining gap between an electrode and a workpiece, and periodically applying a pulse voltage between the electrode and the workpiece to generate an electrical discharge. This is a method of processing the surface of a workpiece by

を有している。The resulting satin surface not only has a larger difference in unevenness and a much more regular shape than mechanical impressions made by metal particle projection, but also has a shape that is independent of the roll manufacturing method and hardness. In addition, the metal structure on the roll surface is hardened by electrical discharge, making it ideal for use as a rolling roll, and has many other advantages.
