Abstract
A device for manufacturing a cutting insert green body by compacting a powder includes a die having an upper die part and a lower die, an upper punch and a lower punch, at least one of which is moveable along a pressing axis in relation to the die. The upper and lower die parts, when joined, define a die cavity that defines the shape of the green body to be formed by the compaction. At least one of the lower and upper die part has a pressing bore extending from the cavity for receiving the lower and upper punch. The upper die part has an upper surface that, at least in one direction, extends rectilinearly, and the upper die part has an upper opening in the upper surface, through which the upper punch is arranged to be forwarded into the cavity.
