According to the customs data in 2021, China exported 4.80 billion carats of synthetic diamond powder with the average price of US$0.04/carat; imported 130 million carats of synthetic diamond powder with the average price of US$0.17/carat. The data fully reflect the fact that China is only a large country in synthetic diamond, but not a powerful country.

Recently, 360powder.com learned that Shenzhen Zhongji Micro Material Co., Ltd. (Hereinafter referred to as “Zhongji Micro Material”), a high-tech enterprise specialized in R&D, production and process innovation, in order to provide the customers with comprehensive application solutions for grinding, abrasion and polishing system of materials for mechanical and chemical processing, will create an industrial layout with Shenzhen as the application center, the laboratories in the United States and Japan as the research and development center, and three production bases of processing, new materials and chemicals as the delivery center, making full preparation for becoming the international leading precision grinding and polishing solution provider.

01 Introduction to Products

So far, Zhongji Micro Material has achieves the comprehensive independent research and development and mass production of the diamond agglomerated grinding material, grinding fluid, and even the auxiliary grinding pad.

01 Small Particle Diamond Agglomerated Grinding Material

A kind of diamond agglomerated grinding material developed independently by Zhongji Micro Material with ball-like shape feature, presenting multi-edge structure in microscope view, and showing slight luster of natural mineral is shown as follows. It maintains high grinding force in the process of grinding, and achieves the surface quality which is impossible for other diamond grinding materials, and also has the advantages such as high utilization rate of diamond, fast cutting rate, and optimal surface consistency of processed workpieces, so it is widely used in grinding and polishing of micro-crystalline glass, sapphire, silicon carbide, gallium nitride, alloy, and other hard and brittle materials.

02 Agglomerated Diamond Grinding Fluid

Based on the premium diamond agglomerated grinding material, the special formula is used to achieve uniform dispersion, high removal rate and shallow scratch, so it has the advantages such as stable grinding rate, high utilization rate, fast cutting rate, and good consistency of processed surfaces. It has to be mentioned that the resin grinding pad series developed independently by Zhongji Micro Material can be used widely in the grinding of hard and brittle materials such as micro-crystalline glass, sapphire, silicon carbide, gallium nitride, zirconia ceramics, and alloys.

03 Resin Grinding Pad

As a significant mark by which Zhongji Micro Material is different from the other grinding material enterprises, Grinding pad is made of imported resin material and special additive formula through mold pressing, and designed in a quadrilateral shape structure of surface, so as to maximize the storage of grinding media and the effective removal of debris, reduce the scratch; furthermore, due to the mesh topology structure, the grinding powder can keep full contact with the workpieces, so as to guarantee the stable grinding efficiency.

02 Application Cases

The Company has made a number of key technology breakthroughs in development of high standard precision grinding and polishing materials by integrating the world’s most advanced technology R&D capabilities. In this field, some products manufactured by the Company take the technically leading position in the world. Oral expressions words cannot be taken as evidence. Taking the common resin diamond wheel as an example, Zhongji Micro Material introduced its performance standards as follows:

- High removal rate of workpiece;

- Good retention of grinding wheel form;

- High surface finish of workpiece;

- Long service life, etc.

The users of the diamond agglomerated grinding material have reported impressive figures – less consumption of grinding wheel with a reduction rate up to 70%. It is precisely due to the enhanced microscope cutting force of diamond wheel in grinding processing, the diamond agglomerated grinding material is particularly suitable for hard and brittle materials that are difficult to be processed, and can be taken the preferable material for processing with high finish and high cutting force.
