Tungsten Carbide Cutting Tools Grades

Tungsten carbide cutting tools is an important tools indispensable, whether ordinary machine tools, or advanced CNC machine tools (NC), machining centers (MC) and flexible manufacturing systems (FMC), the tools must rely on to finish machining. Development of tungsten carbide cutting tools have a direct impact on improving productivity and processing quality. Materials, structure and geometry of the cutting tools is to determine the three elements, including the performance of tungsten carbide cutting tools materials plays a key role.tungsten carbide cutting tools materials mainly tungsten carbide, the grade is usually divided into three categories:

1. YG class (WC-Co type): This class tungsten carbide tools manufacturer has good toughness, wear resistance, thermal conductivity, etc., mainly for machining cast iron, non-ferrous metals and non-metallic.
2. YT class (WC-TiC-Co type): Added to TiC material, so that the material of increased hardness and wear resistance, but reduced bending stiffness. Kind of cemented tungsten carbide has high hardness and high heat resistance, adhesion, good oxidation resistance, suitable for machining steel, cutting tools wear small, high durability.
3. YW class (WC-TiC-Ta-Co Class): Add TaC materials in order to improve the strength of the tools, toughness and red hardness. Such tungsten carbide material has a high temperature hardness, high temperature strength and strong antioxidant capacity, particularly suitable for processing a variety of high-alloy steel, heat-resistant alloys and various alloy cast iron.
