Ceramic binder is an inorganic binder, chemical stability, heat resistance, corrosion resistance, high porosity, and high efficiency of this binder manufacturing of the grinding wheel wear small, can maintain the geometric shape of the grinding wheel , the widest range of applications. Suitable for grinding ordinary carbon steel, alloy steel, stainless steel, cast iron, carbide, non-ferrous metals. However, ceramic bonded grinding wheel brittle, can not be subject to severe vibration. Generally only be used at a speed of 35 m / s within. ?????Resin binder is an organic binding agent, such a binding agent manufacturing a high strength of the grinding wheel, having a certain flexibility, low heat resistance, self-sharpening, production is simple, the process cycle is short. Manufacturing work speed higher than 50 m / s of the wheel and a thin wheel. The scope of its application after the vitrified bond, widely used for coarse grinding, snagging, cutting and freedom of grinding, such as grinding steel ingots, castings playing burr. Can manufacture high-speed, high-quality finish wheels, heavy duty cutting, as well as a variety of special requirements of the grinding wheel.

Grinding wheel finer the particle size, the smaller the roughness values Should be selected with the workpiece material affinity abrasive grinding wheel (specific reference select) Abrasive hardness of workpiece material soft, sticky, hard abrasive should be used; hard, brittle election softer abrasive. A grinding wheel having a larger diameter wheel, increasing the wheel width can reduce the surface roughness Good wear resistance diamond pen, the right edge shape and mounting angle, when appropriate trimming dosage (Longitudinal feed should be small), make abrasive cutting edge to get a good contour, reduce the surface roughness .
