FIELD: manufacturing technology.
SUBSTANCE: invention relates to formation of plate segment for mechanical refiner or disperser. Plate segment is cast. Plate segment has a front side having a grinding surface and a rear side having a third cast surface located on the connection between the first cast surface and the second cast surface. First cast surface is perpendicular to second cast surface. First cast upper surface is machined and the second cast surface is machined. Third cast surface stays between the first machined surface and the second machined surface.
EFFECT: reduced possibility of formation of sharp edges on segment.
