The exhibition scale of SNEC has evolved from 15,000sqm in 2007 to over 150,000sqm in 2020 when it attracted over 1400 exhibiting companies from 95 countries and regions all over the world and the overseas exhibitor ratio is over 30%. SNEC has become the biggest international PV tradeshow with incomparable influence in China, in Asia and even in the world.

Grinding wheels are often referred to as “industrial teeth”. It generally refers to a solid round object (mostly round with a through hole in the center) formed by bonding coarse abrasive compounds together, which can be used on the outer edge. Numerous hard, sharp, and temperature-resistant small abrasive grains continuously cut and remove the surface of various materials, so they have a pivotal position in industrial production.

However, There will be a phenomenon of sticking on the surface of the grinding wheel when the grinding wheel is grinding a 22/25mm camshaft,  resulting in a decrease in efficiency and an increase in the frequency of dressing.

Synthetic diamond tools are a more stable quality product because the structure can be controlled more precisely through the manufacturing process and the quality can be predicted in advance.

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.
