Cutting plate and method and compression mold for producing a green body of the cutting plate

A cutting plate for drilling or milling made by a compression tool, the compression tool being configured to:

• multiaxially press a powder mixture of a hard metal component and a binder to form a green body;
• and
• sinter the green body, which after pressing includes two substantially parallel main surfaces and a peripheral edge surface extending between the main surfaces at a periphery thereof and connecting the same, the two, parallel main surfaces each including depressions extending at least partly to the peripheral edge surface such that cutting edges are formed at an intersection of a bottom of the depressions and at least a part of the edge surface, wherein the powder mixture is supplied to a compression mold having a cavity, which is defined by side punches moveable along at least a first direction for forming the edge surfaces and at least one heading punch moveable substantially perpendicular to the first direction for compacting the powder mixture to form a cutting plate green body, wherein a heading tool is used, which is moveable perpendicular to and towards the main surfaces, the heading tool including two parts, one of the parts being a main punch and the other part being an independently moveable form punch wherein the pressing step includes a first pressing step wherein the form punch is moved towards the powder mixture to form a preliminarily compressed portion of the green body adjacent the peripheral edge surface and including an area designated to become an area of a minimal final thickness of the green body, and a second pressing step wherein the main punch and the form punch are both moved towards a final position to provide the green body with its final dimensions of the parallel main surfaces including the depressions, wherein the depressions are provided at the bottom thereof with chip-breaking and/or chip-forming projections and/or recesses as produced only by the pressing of the powder mixture into the green body.
