Abstract

See full text

A device for manufacturing a cutting insert green body by compacting a powder includes a first punch, a second punch having a punch edge that has a curvature around the circumference of the punch edge that is at least partially non-perpendicular with a pressing axis of the device, a first die part, and a second die part. When the first and second die parts are joined together when filling the die with powder, one of the first and second die parts is on top of the other and, when the device is in a position ready for filling of powder into the die, the device presents a cavity defined by the lower die part, a punch being introduced into the lower and upper die part. An opening in an upper end surface of the upper die part enables filling of the powder into the cavity.
