1: Zong Gangyu (A) features: high hardness, toughness. Application: suitable for grinding of medium and high tensile strength metal materials, such as general carbon steel, alloy steel, malleable cast iron, hard bronze, etc..
The thicknesses of the grinding wheel mesh represents a larger number of grinding wheel the finer grain size, surface roughness and productivity related. Coarse grinding, the grinding allowance, the surface roughness value is large, coarse grain should be selected. Because of coarse grit and large porosity, the grinding depth can be larger, and the grinding wheel is not easy to block and heat. In fine grinding, the allowance is small, the roughness value is low, and the finer abrasive particles are selected. Generally speaking, the finer the abrasive grains, the better the grinding surface roughness. What size is appropriate?
