In recent years, with the rapid development of ultra-precision grinding technology for high speed grinding, grinding wheel,cutting wheel, ceramic and resin bonded grinding wheel can not meet the production needs metal bonded grinding wheel because of its combination of high strength and good formability long life and other significant characteristics and production has been widely used.
The center of the diamond wheel with diamond abrasive materials, respectively with the metal powder, a resin powder, ceramic, and the plated metal as a binding agent, made the through-hole round Bonded Abrasives referred to as a diamond grindstone.
Now that we first understand the resin powder and plating metal as a binding agent made wheel. Resin diamond grindstone and electroplated diamond grinding wheels of the main difference lies in the different binding agents, resin diamond grindstone mainly using phenolic resin plus a small amount of metal powder as a binding agent, electroplated diamond grinding wheel by electrodeposition method will be a nickel-cobalt alloy deposited on the metal substrate surface and fixing diamond abrasive grinding wheel, Production, the main difference is that their performance:
1, in terms of processing efficiency, due to the higher grade of abrasive electroplated grinding wheel and only a layer of abrasive, thermal performance has its own advantages, so efficient processing of electroplated diamond grinding wheel;
2 aspects of life, plating grinding wheel is only one layer of abrasive, plating the life of the wheel will be inferior to resin diamond grinding wheel;
3, the machining accuracy for the surface roughness of the workpiece, the same particle size of the case, the electroplated grinding wheel machining out of the surface roughness should be some difference.

The soft coating self-lubricated tool refers to the solid lubricant is coated directly on the surface of the tool by way of the coating, in order to achieve a self-lubricating function of the tool, also known as self-lubricating coating tool such coated tool [4]. The main component of the soft coating having a low friction factor of a solid lubricant, such as MoS2, WS2, etc., lower shear strength of those having a layered structure of the solid lubricant and easily attached to the friction surfaces in the cutting process, thereby starting to the anti-friction effect.abrasive manufacture

In addition, the cutting process, there is transferred to the surface of the workpiece material in the solid lubricating film of the surface of the tool, to form a lubricating film, so that the friction during the cutting process occurs in between the transfer film and the lubricating film, so that friction occurs in the inside of the solid lubricating film, which can be reached to reduce friction, prevent caking, reduce the cutting forces and temperatures, the purpose of reducing tool wear. Different with the ordinary hard coat cutting tools of TiN, etc., the soft coating, self-lubricating tool by depositing a coating having lubricating properties in the surface of the tool, it is possible in the cutting process to play a good antifriction lubricating effect. At low cutting temperature (<400 ° C), used with a hexagonal layered structure of the sulphides, such as MoS2, WS2, MoS2/Ti (Mo, Cr, Zr, etc.) and WS2 / W, etc., and its advantages and workpiece the friction coefficient of the friction material composition is very low, only about 0.1; when the cutting temperature is higher (1000 ° C or so), the soft metal Ni, W, Al, Ti, etc., has a better friction-reducing effect .non woven abrasive
