Tool Wear of Poly Crystalline Diamond in Cutting WC-Co Cemented Carbide with High-Pressure Coolant Supplied
In order to identify an effective PCD tool for the high-speed cutting of WC-16 mass% Co cemented carbide, the
influences of diamond content and diamond particle size on the tool wear were experimentally investigated. As the WC-16
mass% Co cemented carbide was turned with high-pressure coolant supplied, the tool wear was experimentally investigated.
The following results were obtained: (1) In turning WC-16 mass% Co cemented carbide with the PCD tool, the wear
progress slowed down considerably by using the high-pressure coolant supplied method. (2) In the case of the cutting of
high-pressure coolant supplied by the PCD tool, the tool wear of the PCD tool decreased with the increase in the diamond
particle size. (3) In the case of the cutting of the high-pressure coolant supplied by the PCD tool, which has a large diamond
particle size, WC-16 mass% Co cemented carbide could be cut at the higher cutting speed of 1.167 m/s.
