Product description
The hardness of CBN is higher than that of ordinary abrasives. Higher hardness means more cutting power and sharpness; The high wear resistance of CBN means that it is more difficult to wear than ordinary abrasives; The ability to maintain the shape of abrasive particles is one of the main characteristics of CBN as a high performance abrasive. CBN has a high compressive strength, which means it can keep the particles intact and unbreakable when used under harsh conditions. CBN has good thermal conductivity and can achieve cold cutting during grinding.
1, high hardness, high toughness
High hardness and high toughness cubic boron nitride (CBN) is the superhard material synthesized by human, whose hardness is second only to diamond. It is much higher than ordinary corundum and silicon carbide abrasive, so it has
Better cutting ability, sharper.
2, high temperature resistance, good stability
The grinding wheel is ideal for metal materials sensitive to grinding temperature, such as quenched steel, high vanadium high speed steel and aluminum high speed steel.
3. Strong chemical inertness
Cubic boron nitride is not easy to react with iron group elements, so it is suitable for high speed steel, tool steel, die steel, high alloy hardened steel, chromium steel, nickel alloy, powder metallurgy
Steel and superalloy, such as high temperature, high hardness, low thermal conductivity materials are very suitable for grinding.
4, good thermal conductivity
The thermal conductivity of CBN is 10 to 100 times that of the grinding wheel, so the grinding heat information speed can be exported and one piece of thermal deformation can be reduced. Very suitable for grinding materials with low thermal conductivity
Suitable, all kinds of spraying (welding) materials: nickel base, iron base, etc.; Wear-resistant cast iron materials: vanadium-titanium cast iron, high phosphorus cast iron, chilled cast iron, etc. Titanium alloy class: such as TC4, etc.
5, good grinding performance, good processing surface quality
The dry cubic boron ammoniate grinding tool can maintain the sharpness of abrasive micro knife for a long time, which will make the machining accuracy and surface roughness value of the added piece reach a more ideal effect, because
This can increase the durability of the workpiece by 10%-30%. So even if the batch processing of the workpiece, will always obtain a higher shape, accuracy and consistency. CBN wheel grinding can obtain high dimensional accuracy and low surface roughness, and the machining surface is not easy to produce cracks and burns, and the residual stress is small. Add the Xia surface quality has been improved, generally without pear grain, not easy to burn
Damage, and residual compressive stress can be obtained to improve the fatigue strength of a piece, usually, the durability of a worn piece can be increased by 30-50%.
6, strong wear resistance, long life
CBN grinding wheel grinding ratio can reach 3500-5500, north ordinary corundum grinding wheel is 100 times higher than diamond grinding wheel, 3-5 times higher than diamond grinding wheel.
