Grinding wheel is an important part of the abrasive and abrasive tool industry. The abrasive mold industry plays an increasingly important role in mechanical production, and grinding wheel plays an indispensable role. With the development of science and technology, the growth of new materials and the continuous development of machining to the direction of high quality, high precision, high efficiency and automation, the application range of ceramic bonded diamond grinding wheel is more and more wide and the dosage is increasing.
Ceramic BONDED DIAMOND GRINDING WHEEL HAS HIGH STRENGTH, good heat resistance, sharp cutting, high grinding efficiency, not easy to heat and clog in the grinding process, small thermal expansion, easy to control machining accuracy. Compared WITH Resin Bonded Diamond Wheel, it solves the problems of low life of resin diamond wheel, low grinding efficiency and easy deformation of the grinding tool itself in the grinding process.

1, abrasive and its selection
Abrasive is the main raw material, manufacturing grinding with diamond abrasive with high hardness, high compressive strength, wearability, the diamond abrasive grinding in grinding of hard brittle materials and the ideal of hard alloy tools, not only high efficiency, high accuracy, and good roughness, abrasive consumption, long service life, and can also improve the working conditions. Widely used in common abrasives difficult to process low iron content of metal and non-metal hard brittle materials, such as hard alloy, high aluminum Flap Wheel

Porcelain, optical glass, agate gems, semiconductor materials, stone, etc.
2, granularity and its selection
Particle size refers to the size of abrasive particles. Particle size can be divided into two groups: abrasive and micro powder. The abrasive particles are sorted by screening, and their size number is expressed as the number of holes in one inch length of the screen. The choice of abrasive particle size is mainly related to the surface roughness and productivity. Coarse grinding, the grinding allowance is large, the required surface roughness value is large, should choose a coarser abrasive. Because of coarse abrasive particles, large pores, grinding depth can be large, grinding wheel is not easy to plug and heat. In fine grinding, the allowance is small and the required roughness value is low, so fine grinding particles can be selected. Generally speaking, the finer the abrasive particles, the better the grinding surface roughness.
