The process features CBN

CBN abrasive hardness higher than normal. High hardness means cutting ability stronger, sharper; CBN has a high abrasion resistance, which means it harder than ordinary abrasive wear; ability to maintain the shape of abrasive CBN as one of the main characteristics of high-performance abrasive; CBN's high compressive strength, which means that in the harsh  cutting tools  of use it can remain intact and not broken particles; CBN has good thermal conductivity, the grinding can be achieved when cold cutting.
1, high hardness, high toughness
High hardness, high toughness, cubic boron nitride (CBN) is a human synthetic superhard material hardness only to diamond is much higher than the normal corundum and silicon carbide abrasive, and thus has a better cutting ability, more sharp
2, high temperature resistance, good thermal stability
Cubic boron nitride can withstand high temperature of 1250-1350 ° C, the heat resistance than diamond 800 degrees even higher; the grinding and cutting ferrous materials, debris sticking phenomenon does not occur in the grinding of hardened steel, high vanadium high speed steel, aluminum and high-speed steel for metal grinding temperature sensitive material is the best of the wheel.
3, the chemical inertness
Cubic boron nitride and iron group elements is not easy to produce a chemical reaction, so for a variety of high-speed steel, tool steel, tool steel, high alloy hardened steel, chromium steel, nickel alloys, powder metallurgy steel and high temperature alloys such as high temperature, high hardness , low thermal conductivity of the material is very suitable for grinding.
4, good thermal conductivity
CBN grinding wheel corundum thermal conductivity up to several hundred times, and thus be able to export the grinding heat quickly, reducing workpiece thermal deformation. Low thermal conductivity of the material for grinding is very appropriate. A variety of spray (welding) Material: nickel, iron, etc.; cast iron type material: vanadium - titanium cast iron, high-phosphorus iron, chilled cast iron, etc.; titanium: such as TC4 and so on.
5, the grinding performance, good surface quality
As CBN abrasive grains can be maintained long-term micro-edge sharpness, will make the workpiece machining  grinding wheel  and surface roughness values ​​are achieved more satisfactory results, thus allowing the workpiece durability increased by 10% -30% . Therefore, even if the batch processing of the workpiece, will always get a high shape accuracy and consistency. CBN grinding wheel to achieve high dimensional accuracy and low surface roughness of the machined surface is not easy to produce cracks and burns, the residual stress is small. Improve the quality of the machined surface, generally no cracks, not burn, and will receive the residual compressive stress, fatigue strength significantly improved workpiece, usually by grinding the workpiece can be increased by 30-50% durability.
6, wear resistance, long life
CBN grinding wheel ratio up to 3500-5500, a hundred times more than ordinary high corundum grinding wheel, diamond grinding wheel 3-5 times higher than that.
7, environmental pollution, energy saving
Without too much powder dust.
8, high efficiency, good overall economic efficiency
Sharp grinding, grinding force is small, CBN grinding wheel dressing cycle is long, finishing less the amount, the replacement for a long time; long life cycle, grinding ratio, getting a better economy, in use to maintain good shape, without regular replacement wheel and wheel dressing, saving time, improving working conditions, is conducive to the machining operation.
