摘要： PROBLEM TO BE SOLVED: To keep cutting balance before and after diameter regulation in a throw-away type drill having a diameter regulating mechanism capable of regulating the outer diameter of the drill.
SOLUTION: In this drill with the diameter regulating mechanism, throw-away tips having a cutting edge are arranged at the tops of a pair of chip discharge grooves, and the same number of throw-away tips are arranged facing to each chip discharge groove. The outer diameter of the drill is regulated by moving, in the diameter direction, only the throw-away tips having an outer peripheral blade disposed outermost side in the diameter direction. In the drill with the diameter regulating mechanism, cut width between faced cutting edges does not change before and after regulation of the outer diameter of the drill, so that the cutting balance is kept and stable drilling is performed.

摘要： PURPOSE:To provide a mold of a carbon fiber-containing friction material capable of fully exhibiting abrasion properties as a friction material and showing excellent adhesion strength with a back plate of metal or ceramic for imparting reinforcement and thermally insulating effect to the mold. CONSTITUTION:In a molded carbonaceous friction material contained at least carbon fibers, carbon and a metal and/or an alloy, the metal and/or the alloy are poor on the front surface acting as the friction surface of the mold product, while are rich in the backside surface, as the content of the metal and/or the alloy increases stepwise or gradually from the front surface toward the back surface. Thus, the molded material has higher adhesion strength to the back plate than that of a conventional carbonaceous friction material and the front surface acting as the friction surface has higher friction coefficient and abrasion resistance resulting in prolonged application life.
