In our lives in this kind of material for the CBN wheel is often used, however, how the use of CBN wheel? In general, higher than that of ordinary abrasive hardness of CBN wheel. High hardness means cutting more and more sharp; CBN has a high abrasion resistance, which means it is more difficult than conventional abrasive wear; ability to keep the abrasive shape is one of the main features of the CBN as a high-performance abrasive; CBN grinding wheel the compressive strength is high, which means that when used in harsh conditions it can maintain the particles is complete and easily broken; CBN has a good thermal conductivity can be achieved, when grinding cold cutting. At the same time it is more important to CBN grinding wheel with a high temperature, good thermal stability. The cubic boron nitride can withstand a high temperature of 1250-1350 degrees Celsius, even higher than the diamond heat resistance of 800 degrees Celsius; sticky crumbs phenomenon appears in the grinding and cutting ferrous materials, not, in the grinding of hardened steel, high vanadium high speed metal material such as steel, aluminum, high-speed steel is more sensitive to the grinding temperature is DC wheel. An Analysis of CBN grinding wheel related use characteristics of the process.

Diamond wheel, CBN grinding wheel this is known as the generation of super-hard material products, they are immediately applied to the ordinary grinding wheel play difficult direction, like precision cutting tools, tool steel, stainless steel, the production of other types of hardened alloy steel and high temperature alloys and processing.
CBN is a hardness of tight inferior diamond superhard material. It is a non-nature-forming substance. CBN is the hexagonal boron nitride is exposed to high temperature, using a method similar to the graphite, synthetic diamond made of artificial and synthetic substances. The company now usually superhard abrasive material instead of the diamond abrasive.
And Diamond is different, do not dissolve in the related alloys of iron, nickel, etc. at high temperatures in the CBN. Our precious gems, but soluble in these metals, resulting in the formation of carbides, thereby reducing the service life of the grinding tool.
Obviously, CBN is a very durable material and is a really useful abrasive. Now, grinding tools and cutting tools are the use of CBN precision manufacturing.
I will carefully balanced and accurate play to the performance of the CBN, to produce the best performance of CBN wheel. A CBN cutting wheel, also like other precision instruments, proper use and careful maintenance, so they can maximize the utility.
