Document Type and Number:

Japanese Patent JP2007130719

Kind Code:

A

Abstract:

To provide a throw-away tip and a grinding method for it, achieving compatibility between high accuracy and mass productivity.

In this throw-away tip 1, a cutting blade 5 is formed on at least one ridge part of ridge parts of intersecting upper and side surfaces, a cutting face 2 is formed on the upper surface extended from the cutting blade 5, a flank 4 is formed on the side surface extended from the cutting blade 5, and further fitting reference surfaces 6a, 6b for positioning the cutting blade 5 in a predetermined position are formed on at least one side surface. A recessed part 7A recessed from at least one surface of the upper surface and the lower surface or a projecting part projected from that is formed, and the inner wall surface of the recessed part 7A or the outer peripheral surface of the projecting part is provided with grinding reference surfaces 7a, 7b formed for reference to grinding in grinding the fitting reference surfaces 6a, 6b.
