With the development of science and technology, more and more high-strength, high-hardness materials are widely used in the aerospace, shipbuilding and machinery industry, and these materials are often difficult to be processed with conventional abrasives. In this case, superhard abrasives are produced and developed.

Superhard abrasives are abrasive products that are made of synthetic diamonds and CBN cubic boron nitride as main components, whose superiority is highlighted in the following aspects.
1. It can process high hardness materials that are difficult to be processed by conventional abrasives;
2. Less wear and tear during processing; Good economic results can be obtained under reasonable using conditions;
3. Longer service life, high grinding efficiency and low power consumption;
4. Low grinding temperature can reduce and avoid defects such as workpiece cracks and burns.

Diamond is the most hard material known in the world at present, but natural diamond resources are limited and expensive, and synthetic diamond abrasives have good grinding performance. Due to high hardness, synthetic diamond abrasives have good abrasion resistance, sharp edges and small friction factor. However, when synthetic diamond is at a temperature of 600-700 or above, its carbon atoms can easily diffuse into the materials of iron elements to form carbonized iron, which will accelerate diamond wear, so it is not suitable for grinding steel and other plastic materials.
