摘要： PROBLEM TO BE SOLVED: To solve the problem that (1) an electrical discharge machining, which is often used in cutting super-high stiffness materials such as a cBN sintered body or a diamond sintered body, has difficulty in cost reduction of products due to slow working speed, and that (2) a laser beam machining, which requires a post processing due to quality problems of working end surface, also suffers a high working cost. SOLUTION: Damaging by heat at the time of working is prevented, a good working surface is obtained and taper of the working surface can be kept down small concurrently, by injecting cooling water near the part of working during cutting work of the super-high stiffness material. Therefore a working method allowing high speed, little damaging by working and handling of various working figuration is provided, and industrially useful effects are brought about.
