Vitrified bond diamond wheel with high strength, heat resistance, cutting sharp, high grinding efficiency, grinding process is not easy fever and congestion, the small amount of thermal expansion, shape retention is good, easy to control precision, with resin bonded diamond grinding wheel phase than he solves the low resin diamond grinding wheel life low efficiency, poor shape retention, abrasive itself during the grinding process variability issues.
Carbide has high hardness, wear resistance, high strength, corrosion resistance and a series of excellent performance, especially its high hardness and wear resistance. With the development of technology, as a tool material carbide, instead of the traditional high-speed steel, are widely used, such as turning, milling, planning, etc., but some scholars have proposed a "cut instead of grinding" concept, which the surface quality carbide put forward higher requirements.
For now, for grinding carbide tools, most manufacturers choose resin diamond grinding wheel, grinding can be obtained through the results we want, but the low grinding efficiency. For resin diamond grinding wheel is generally used for roughing particle size of 100-120 mesh, and for the ceramic diamond grinding wheel, we generally use 120-150 mesh to be rough, even higher metal removal rates and still get better surface finish. Vitrified bond more strongly than the resin bond diamond bonding and a greater porosity between the abrasive particles and a binder, each of pores is equivalent to a single-point cutting tool edge chip space. For the same grinding allowance, ceramic diamond grinding wheel efficiency than resin bonded diamond grinding wheel to about double, but the life is 2-3 times the resin diamond grinding wheel.
For now widely used carbide tools, the kind of growing, continuous improvement of quality, which requires hard alloy surface finishes better improved, and vitrified diamond grinding wheel due to the shape retention is good, fundamental solution to this problem, whether it is the grinding efficiency, production costs and grinding accuracy has been greatly improved. This technology development and promotion of the tool manufacturer's overall costs and benefits of a qualitative change.
