Suzhou cbn grinding wheel is made of CBN (cubic boron nitride) abrasives as raw materials, and metal powder, resin powder, ceramics and electroplated metal are used as binders to make various shapes of products, which are used for grinding, polishing, and grinding tools. Called CBN Abrasives. Compared with diamond grinding wheels, CBN has more advantages in processing ferrous metals. Next, the editor will analyze the relevant process characteristics of Suzhou cbn grinding wheel in detail.
High hardness and high toughness Cubic boron nitride (CBN) is a superhard material synthesized by humans whose hardness is second only to diamond and is much higher than ordinary corundum and silicon carbide abrasives, so it has good cutting ability and sharper.
2. High temperature resistance and good thermal stability
Cubic boron nitride can accept high temperatures of 1250-1350 degrees Celsius, which is higher than the heat resistance of diamond at 800 degrees Celsius; when grinding and cutting iron materials, there will be no chip sticking phenomenon. It is used in the grinding of hardened steel and high vanadium at high speed. Steel, aluminum high-speed steel and other metal materials that are more sensitive to grinding temperature are ideal grinding wheels.
3. Strong chemical inertness
The cubic boron nitride in the Suzhou cbn grinding wheel is not easy to chemically react with the iron group elements, so it is suitable for various high-speed steel, tool steel, die steel, high alloy hardened steel, chromium steel, nickel alloy, powder metallurgy steel and high temperature alloy, etc. It is very suitable for grinding materials with high temperature, high hardness and low thermal conductivity.
4. Good thermal conductivity
The thermal conductivity of CBN can reach dozens to a hundred times that of the corundum grinding wheel, so the grinding heat can be quickly discharged and the thermal deformation of the workpiece can be reduced. It is very suitable for grinding materials with low thermal conductivity. Various spraying (welding) materials: nickel-based, iron-based, etc.; wear-resistant cast iron materials: vanadium-titanium cast iron, high-phosphorus cast iron, chilled cast iron, etc.; titanium alloys: such as TC4, etc.
The above is the analysis of the editor on the high hardness, high toughness, high temperature resistance, good thermal stability, strong chemical inertness and good thermal conductivity of the Suzhou cbn grinding wheel. The main part is the above part, I hope it will be helpful to everyone.
