Method for manufacturing throwaway tip and apparatus for aligning green compact

摘要

The present invention provides a method for manufacturing a throwaway tip in which a green compact Q obtained by press-forming raw material powder for the throwaway tip is placed and sintered on a sintered 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 sintered plate 8 in plan view. According to the present invention, it is possible to obtain a throwaway tip having sintering accuracy.
