Precision Machining of Cemented Carbide with Small Diameter Ball Endmills

Application to Production of Minute Metal Mold

Abstract

The precision component made from a minute metal mold becomes the necessity and indispensable along with miniaturizing and making of an industrial product high density. Moreover, the material of the metal mold that is excellent in durability in high hardness is used. Then, to apply the cemented carbide to a minute metal mold, the minute shape processing by cutting to the cemented carbide was done with the cBN tool and the diamond tool. As a result, specular surface is obtained, and it has been understood that cutting is effective in the processing of a minute metal mold.
