The strength of diamond is an important index to ensure the cutting performance. High strength will make the crystal is not easy to break, the abrasive particles are polished in use, sharpness decreased, resulting in deterioration of tool performance. When the strength of diamond is not enough, it is easy to be broken after impact and difficult to undertake the heavy cutting task. Therefore, the strength should be between 130 and 140N.

The grinding wheel is a necessary tool for the grinding machine. To make the grinding wheel grind to an accurate size and smooth surface, it is necessary to prevent vibration during the grinding process.

When grinding cemented carbide, its grinding efficiency is several times that of silicon carbide. When grinding W12 Cr4V4Mo high-speed steel with poor grinding performance, the average efficiency is increased by more than 5 times.

Vitrified bond is a widely used bond at present. Its performance is between the microbial metal bond and the resin bond, especially the ceramic bond in the vitrified bond diamond grinding wheel has the holes of the motorcycle, and has cooling, dust and dust retention. So it is not easy to block and burn during grinding, which satisfies the needs of material grinding and high-efficiency grinding. The evolution of the resin bond diamond grinding wheel solves the problem of the diamond grinding wheel. The problem of low life, low grinding efficiency, and easy deformation of abrasive tools during the grinding process.

CBN insert: Artificial cubic boron nitride cutting tool, at high temperature can also maintain the characteristics of high hardness, mainly for processing iron parts.

The diamond pellets or diamond pallets rings are bonded to the matrix material, and the particle size of the pellets ranges from W7 to W40.

The grinding wheel state can be divided into “normal wear”, “abrasive particle off”, “chip blocking”, “abrasive particle passivation” and other four forms. Observing the state of the grinding wheel currently in use and adjusting the grinding wheel to a more suitable state is the first step to improve the grinding process.

In recent years, with the rapid development of modern machinery industry, the performance requirements of processed workpieces have become higher and higher, and the application of high-efficiency and high-precision double-end grinding technology in the processing field has also been expanding. It has been widely used in air conditioners, automobiles, and Industries such as bearings, hydraulics, and magnetic materials are also expanding in application fields such as molds, tools, aerospace, and semiconductors, and related reports are also increasing.

Moresuperhard Diamond/CBN grinding discs are widely used for grinding the surface, suitable for steel, cast iron, copper, carbide,PCD/PCBN inserts, hard alloy, ceramics, monocrystalline silicon and other processing. It can be widely used in hydraulic pneumatic components, hydraulic motor parts, automobile fuel pump parts, refrigeration compressor parts, oil pump oil.

China International Machine Tool Show (CIMT 2021) will be held on 2021 at China International Exhibition Center (new venue) in Beijing. More Superhard will be attend this exhibition, it would be a great pleasure to meet you at the exhibition. We are pleased to invited you join us together in CIMT 2021, which we will showcase our lastest products there at booth E8-B706
