Abrasive application

 

Abrasives are widely used in industry, especially when machining high-precision or low-roughness parts or particularly hard parts, abrasives and abrasives are essential. In addition, grinding wheels are also essential tools for sharpening knives and cutting hard materials.

In the automobile manufacturing industry, the tight fit between the piston ring and the cylinder, the valve and the valve seat, the precision of the transmission and gear, etc., must be processed with abrasives and abrasive tools to ensure. Other related new products, such as media for plastic bonded tumbling mills, save time and increase productivity for deburring large numbers of parts.

The production technology of abrasives has advanced significantly. Diamond grinding wheels are four times more efficient than they were 14 years ago; the total cost of zirconia-alumina grinding wheels for rolling mills is only 25% of what it was in 1948, and the speed is seven times faster.

Characteristics and uses of cubic boron nitride (CBN)

Cubic boron nitride is another new product after the advent of synthetic diamond. It has high hardness, thermal stability and chemical inertness, as well as good infrared transmittance and wide band gap. Its hardness is second only to diamond, but its thermal stability is much higher than that of gold steel. It has great chemical stability to iron-based metal elements. The grinding performance of cubic boron nitride abrasives is very good, not only can it be competent for the processing of difficult-to-grind materials, improve productivity, but also effectively improve the grinding quality of workpieces. The use of cubic boron nitride is a major contribution to metal processing, leading to a revolutionary change in grinding and a second leap in grinding technology.

Strategic Planning:

The products focus on cubic boron nitride superhard materials and superhard tools; follow-up expansion to the entire superhard tools; eventually developed to the field of tools covering a variety of materials, with the "full industry chain of cubic boron nitride" as a lifelong career.

Industry terms:

Tools: refers to grinding and cutting tools used in machinery, automobile, electronics, aerospace, glass and other manufacturing industries, including abrasive tools and cutting tools. According to the different materials used, the tools are divided into ordinary tools and superhard tools. Common tools include common abrasives (common materials such as corundum, silicon carbide, etc.), common tools (common materials such as cemented carbide, high-speed steel and ceramics).

Superhard tools: Superhard tools include abrasives and knives mainly made of superhard materials. Superhard materials mainly refer to the general term for materials with ultra-high hardness such as cubic boron nitride, diamond, and composite materials with these two materials as the main components. Superhard materials are present in the world. The hardest material known in the world, suitable for making tools for machining other materials, especially in machining hard materials, has unparalleled advantages.

Cubic boron nitride material application:

1. Manufacture of abrasive tools. 2. Made of polycrystalline composite sheet as tool material. 3. Special functional materials in electronics, military industry, aerospace, etc.

Abrasives used for manufacturing: suitable for processing both hard and tough materials, such as high-speed steel, tool steel, die steel, bearing steel, nickel and cobalt-based alloys, chilled cast iron, etc. When grinding steel with cubic boron nitride abrasive tools, high grinding ratio and surface quality can be obtained. In metal processing, cubic boron nitride materials are rapidly replacing ordinary abrasives (such as silicon carbide, white corundum, etc.).

This is a developing high-tech project: the company focuses on the research and development, production, sales and service of cubic boron nitride material single crystal, micropowder, and superhard cutting tools. The founding team has completed technical research and development, and improved the quality system. , and build the whole industry chain module with the cubic boron nitride project.
