Characteristics and Application Analysis of Super Abrasives

With the development of science and technology, more and more materials with high strength and high hardness are widely used in many industries, such as aerospace, aviation, shipbuilding and machinery industry. These materials are often difficult to be processed by using ordinary abrasives products, and in this case, super abrasives emerged and are developing.

Super abrasives are made of diamond and cubic boron nitride as the main ingredients, whose advantages are highlighted in the following respects.

A. They can process some high hardness materials that ordinary abrasives products are difficult to machine.

B. Their wear and tear is less in the processing , and under the condition of reasonable use, they can obtain good economic effect.

C. The shape and size of abrasives products change slowly, and they all have long service life. Therefore, we can prolong the time to keep sharp cutting edges, and as a result, we will get high grinding efficiency and less power consumption.

D. Low grinding temperature, but it can avoid some cracks, burns and other defects of artifacts.

Diamond is regarded as currently super hard substance known in the world, but the resources of natural diamond are limited, and it is difficult and expensive for mining. Now we focus on research and develop synthetic diamond as a substitute for natural diamond.

Synthetic diamond has great grinding performance. Grinding wheels consume less, but have high using requirements, which are not suitable for heavy load grinding. The grinding performance of natural diamond is not that good than synthetic diamond, and the cost and loss are high, but we can use more grinding dosage.

Diamond abrasives products have high hardness, good abrasion resistance, sharp edges and corners, low friction, but above the temperature of 600-700, the carbon atoms will easily spread to the iron element materials to form iron carbide, which will accelerate the diamond wear. Therefore, it is not suitable for grinding steel and other plastic materials.

Cubic boron nitride (CBN) is another new superhard material, whose hardness is about 1.5 times than that of corundum, slightly lower than that of diamond. But it can bear high temperature, and its thermal stability and chemical stability are better than that of diamond. Therefore, cubic boron nitride abrasives products are suitable for processing hard black metal toughness. But under the condition of high temperature, it is easy to react with water, so it is commonly used in dry grinding.
