Powder Metallurgy Hob

Application of powder metallurgy high speed steel:

The special and advanced smelting method of powder metallurgy high-speed steel is an innovation of high-speed steel smelting, which creates a new type of steel with properties between cemented carbide and ordinary high-speed steel. The rise of powder metallurgy high-speed steel has made new breakthroughs in tool materials in the machinery manufacturing and processing industry. As a new type of steel with excellent performance, it has gradually been recognized, accepted and loved by people, and is playing an increasingly important role in the machinery industry. .
Powder metallurgy high-speed steel has excellent toughness and machinability, good red hardness, high compressive strength and high wear resistance, as well as high alloy content, high purity, no segregation, fine carbide particles and various It has the characteristics of isotropy and homogeneity, so it has been widely used. It can be used as a tool for processing non-ferrous metals such as titanium and aluminum alloys, as a milling cutter, hob, gear shaper, shaving cutter and other tools for processing gears, and can also be used as a side milling cutter, forming milling cutter and broach. It is also commonly used in twist drills, machine taps, reamers, etc.; in the saw blade industry, powder metallurgy high-speed steel is used as a band saw bimetallic steel strip, as well as precision punching tools and punch dies and other dies. Powder metallurgy high-speed steel is generally 4 to 8 times the price of ordinary high-speed steel, so it is usually used to manufacture sophisticated and complex tools or tools for CNC machine tools. The performance of cutting tools made of powder metallurgy high-speed steel is better than that of ordinary high-speed steel, and the service life is higher than that of ordinary high-speed steel (generally 2~3 times). The application prospect in the tool industry is very promising, and it has attracted more and more people's attention.
