Application of electroplated diamond wheel in cemented carbide grinding technology application of electroplated diamond wheel in cemented carbide grinding technology application of electroplated diamond wheel in cemented carbide grinding

With the development of science and technology and the continuous growth of new materials, machining is developing towards the direction of high quality, high precision, high efficiency and automation. The application scope of electroplated diamond grinding wheel is becoming wider and wider, and the consumption is increasing. Ceramic bonded diamond grinding wheel is mainly used in the machining of high hard and brittle materials such as cemented carbide, semiconductor silicon wafer, diamond composite wafer, diamond cutting tool, new engineering structure ceramics, gem, crystal and magnetic materials, and has achieved good application results.

Electroplated diamond grinding wheel has high strength, good heat resistance, sharp cutting, high grinding efficiency, not easy to generate heat and block in the grinding process, small thermal expansion, good shape retention and easy to control the machining accuracy. Compared with resin diamond grinding wheel, it solves the problems of low service life, low grinding efficiency and poor shape retention of resin diamond grinding wheel, The problem of the variability of the grinding tool itself in the grinding process.

Cemented carbide has a series of excellent properties such as high hardness, wear resistance, high strength and corrosion resistance, especially its high hardness and wear resistance. With the development of science and technology, cemented carbide is widely used as tool material instead of traditional high-speed steel, such as turning tool, milling cutter, planer, etc. some scholars put forward the concept of "cutting instead of grinding", which puts forward higher requirements for the surface processing quality of cemented carbide.

At present, for the grinding of cemented carbide tools, most manufacturers choose resin diamond grinding wheel. Although we can get the grinding results we want, the grinding efficiency is very low. For resin diamond, the particle size of 100-120 mesh is generally used for rough machining, while for ceramic diamond grinding wheel, we generally use the particle size of 120-150 mesh for rough machining. Even with higher metal removal rate, we can still get better surface finish. Ceramic bond is stronger than resin bond, and there are larger pores between abrasive particles and bond. Each pore is equivalent to the chip holding space of the upper edge of single point cutting tool. For the same grinding allowance, the grinding efficiency of electroplated diamond wheel is about twice that of resin diamond wheel, and its service life is 2-3 times that of resin diamond wheel.

At present, the wide application of cemented carbide tools, the continuous increase of types and the continuous improvement of quality require the better improvement of the surface processing quality of cemented carbide. Due to the good shape retention of electroplated diamond grinding wheel, this problem has been fundamentally solved, and the grinding efficiency, production cost and grinding accuracy have been greatly improved. The development and popularization of this technology has qualitatively changed the comprehensive cost and benefit of tool manufacturers.
