Hot Extrusion of Cemented Carbide for Forming Helical End-Milling Blades

The paper describes a hot extrusion process of cemented Carbide for making helical end-milling cutters.The plastic deformation behaviours of tungsten carbide-cobalt alloys are theoretically analyzed and discussed.It is found that the tungsten carbide-cobalt alloys have good plastic deformation processability at high temperature.Hot extrusion process of cemented carbide is suitable for forming some products with special configuration.
