摘要： PROBLEM TO BE SOLVED: To provide a fixing method for a blade exchanging type tip by which a round chip can be rotated by a fixed rotation angle in order to reuse a used blade portion and to avoid disposal of a blade while it is remained in an unused condition. SOLUTION: The fixing structure for the blade exchanging type tip has a depression of a reverse truncated pyramid shape in a rake face and has an angle θ made by the flank of the reverse truncated pyramid and the rake face being 30 to 85 degrees. A round chip 1 is fixed by a holder 14 and a pressing tool 10. The holder 14 has a screw hole 15 for a cap screw, a first sliding face 12 for fixing the round chip and a notch for retaining the round chip at a tip. The round chip pressing tool 10 has a round head drawing pin 13, a long hole 16 for the cap screw and a second sliding face 12' for fixing the round chip. When the round chip pressing 10 is tightened in the holder 14 with the cap screw 11, the pressing tool 10 is moved downward and backward along the first sliding face 12, the pressure welding of the second sliding face 12' and the first sliding face 12 is carried out, and the round chip 1 is retained firmly.

摘要： PROBLEM TO BE SOLVED: To provide an edge replaceable chip rotating a circular chip at a fixed rotation angle for avoiding to reuse a spent cutting edge part and to dispose it with a cutting edge left unused.
SOLUTION: This edge replaceable chip is provided with an inverse truncated pyramid recess in a cutting face 2 and an angle θ of 30°-85° formed between a slant face and the cutting face 2 of the inverse truncated pyramid. This circular chip 1 is fixed by a holder and a presser. The holder is provided with a screw hole for a cap screw, a first sliding surface for fixing the circular chip and a notch for holding the circular chip formed in its tip. The circular chip presser is provided with a circular chip lead-in pin, a long hole for the cap screw and a second sliding surface for fixing the circular chip. When the circular chip presser is fastened to the holder by the cap screw, the presser moves downward and rearward along the first sliding surface to press-contact the first sliding surface and the second sliding surface and firmly hold the circular chip.

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.
