  • Method and device for manufacturing a cutting insert green body
    Patent number: 9956702
    Abstract: A method and device for manufacturing a cutting insert green body, the method includes the step of providing a compression tool having an upper and lower die, and an upper and lower punch. The upper die defines a punch tunnel in which the upper punch slides, and the lower die defines a punch tunnel in which the lower punch slides. The dies define a die cavity to accommodate a powder to be compressed by action of the respective punches to form the green body. Powder in the die cavity is compressed by forwarding the upper punch through the punch tunnel of the upper die and a predetermined distance L through the opening of the lower die. The upper die is displaced relative to the opening of the lower die and the upper punch is removed from the lower die to move the green body out of the lower die through the opening thereof.
