How to choose cbn cubic boron nitride wheel?
Time:2017-9-25 15:06:10  Browse:

With the cutting tool requirements continue to improve, the requirements of grinding technology is also increasing. New knives or grinding tools become more and more complex, with the requirements continue to reduce tool tolerance, and time and cost pressures are also growing.


Cubic boron nitride grinding wheel is a very common product in diamond products, it is also referred to as CBN grinding wheel, in its body cubic boron nitride particles adhere to the ordinary grinding wheel surface is only a thin layer of its abrasive toughness, Hardness, durability is 100 times the corundum grinding wheel, cubic boron nitride is not suitable for grinding carbide and non-metallic hard materials. In the grinding high temperature, CBN alkaline water solution will occur in a chemical reaction, CBN grinding wheel in 300 ℃ alkaline solution will be decomposed in boiling water can be micro-decomposition, the results will be abrasive grain shape is damaged, so grinding, Can only use oily coolant, and can not use water-based coolant. CBN wheel hardness higher than ordinary abrasive. High hardness means stronger cutting force and more sharp; CBN grinding wheel has high wear resistance, which means it is more difficult to wear than ordinary abrasive; the ability to maintain abrasive grain shape is one of the main characteristics of CBN grinding wheel as high performance abrasive; The CBN grinding wheel has a high compressive strength, which means that it can keep the particles intact and not broken when used under harsh conditions. The CBN wheels have good thermal conductivity and are capable of cold cutting during grinding.


Therefore, the choice of cubic boron nitride grinding wheel according to the needs of different customers and use, I will seriously ask the Secretary for customers, and customers to communicate well.
