Method for manufacturing throwaway tip and apparatus for aligning green compact

摘要

A method for manufacturing a throwaway tip is presented in which a green compact Q obtained by press-forming raw material powder for the throwaway tip is placed and sintered on a sintering plate 8. The green compact Q is press-formed so that the density of the raw material powder is gradually decreased toward a predetermined direction R, and the direction R is oriented substantially toward the outer circumference of the sintering plate 8 in plan view. Thus, it is possible to obtain a throwaway tip having sintering accuracy.
