Therefore, the most important requirements for high-speed cutting tool materials are mechanical properties at high temperatures, thermophysical properties, anti-blocking properties, chemical stability (oxidation, diffusivity, solubility, etc.) and thermal shock resistance and coating crack resistance. .
Based on this requirement, PCBN tool materials suitable for high-speed cutting can process a variety of workpiece materials under different cutting conditions. At present, it can cut steel from 2000 to 5000 m/min: 100-500 m/min cutting steel: 100-200 m/min cutting hardened steel.
The current cemented carbide tools are basically tungsten-cobalt carbide, China is rich in tungsten, and 75%~80% of the world comes from China. According to the relevant literature, the world's tungsten photo is so developed and used, only practical for 50 to 70 years. The rapid development of PCBN tools is the direction to solve the tungsten resource problem. In the future development of new tool materials, cubic boron nitride materials will play a more important role in the field of ferrous metal cutting to achieve pollution-free, clean, low-energy green cutting.
PCBN tools have high hardness, wear resistance and chemical stability, and are suitable for green manufacturing such as high-speed cutting, dry cutting, and hard cutting, without environmental pollution caused by cutting fluid. With the rapid development of CNC machining technology and the widespread use of CNC machine tools, the production and application of super-hard tools are becoming more and more extensive. At present, PCBN tools have been widely used in various industries of machining, such as machining of automotive parts, bearings, gears, etc., which has greatly promoted the rapid development of cutting processing and advanced manufacturing technology. Due to its excellent fracture resistance, wear resistance and good chemical stability, PCBN products have become the best tool for cutting hardened steel and various cast irons. Due to the unparalleled superiority of PCBN tools in machining precision, cutting efficiency, tool life, etc., the promotion and application of PCBN tools can greatly improve the processing efficiency while greatly saving costs.
Modern cutting processing, such as green machining, grinding by car, milling, hard machining, high-speed cutting, dry cutting, etc. are all due to the application of PCBN superhard tools, so PCBN tools have become indispensable in cutting. An important means. In the coming years, the share of PCBN tools in a larger market will be irreversible.
