Tungsten carbide is a hard alloy material to compound metal and metal bonding process made by powder metallurgy. It has high hardness, wear resistance, strength and toughness, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness. Based on characteristics of hard alloy, make it become the main material of the insert. However, insert NC CNC grinding tungsten carbide in the production cost occupies a big proportion, reduce the cost of grinding become the big insert manufacturers need to solve the problem nowadays,The main use of tungsten carbide inserts, diamond grinding wheel grinding diamond wheel. According to the bond can be divided into different resin bonded diamond wheel,vitrified diamond wheel,metal combined with Ji Jingang Grindingwheel. Compared with resin bond diamond grinding wheel is widely used in CNC carbide insert grinding in the metal bonded diamond grinding wheel has the advantages of high strength, good abrasion resistance, maintain a good shape, can bear large load, but also its self sharpening, high dressing.

In the process of grinding hard alloy insert, abrasive wear, grinding force increases, resulting in abrasive broken or off, exposed to the sharp edge, this property is called "self sharpening grinding wheel. Self sharpening grinding to normal in a certain period of time, but beyond a certain time after work that should be finished manually, so as to avoid the increase of grinding force caused by vibration, noise and damage the surface quality of the workpiece. The resin bonded grinding wheel has good self sharpening, the machining precision consistency by trimming effect; metal bonded grinding wheel self dressing, dressing in the lack of tungsten carbide debris blocking wheel gap, workpiece. Size consistency, when the debris after the optimal dressing parameters of the grinding wheel surface clogging timely cleaning, dimensional accuracy of the workpiece metal bonded diamond grinding wheel and the workpiece and grinding the resin bonded grinding wheel Consistency reached the same level.

On the market of the same specifications of metal bonded grinding wheel than the resin bonded grinding wheel offer about twice as high, so only consider the price and the ratio of grinding wheel, the choice of metal bonded diamond grinding wheel for tungsten carbide insertis more cost advantage.

The metal binding agent diamond grinding wheel with resin bonded diamond grinding wheel workpiece size precision consistent dressing parameters after optimization; the surface of metal bonded diamond grinding wheel processing products is higher than the value of the roughness of the resin bonded diamond wheel processing products, but it can meet the requirements of CNC carbide insert grinding surface is required; metal bonded diamond grinding wheel the grinding ratio is higher than that of resin bonded diamond wheel.

The price and the grinding ratio of the two kinds of grinding wheels on the market are analyzed comprehensively. It is more economical to use the metal bonded diamond grinding wheel to grind cemented carbide inserts.
