Selection the Bond Agent of Grinding Wheel
There are many kinds of diamond grinding wheel products that have all sorts of shapes and sizes. According to different abrasives, bond materials and manufacturing process of grinding wheel, each kind of grinding wheel has a certain application scope. Improper selection will directly affect the machining accuracy, surface roughness and production efficiency. Therefore,changsha 3 better ultra-hard materials Co.,Ltd. will explain some suitable bond agent of grinding wheel.
The suitable bond agent should be selected according to the grinding method, the grinding speed, surface processing requirements and other conditions. The most commonly used grinding wheel bonding agent is Vitrified bond and resin bond diamond grinding wheel.
Vitrified bond diamond grinding wheel is a kind of inorganic bond, which has stable chemical performance, heat resistance, good corrosion resistance and large porosity. This kind of grinding wheel has high efficiency and small abrasion, and can keep the geometry shape of grinding wheel, which has the most widely application scope and is suitable for grinding ordinary carbon steel, alloy steel, stainless steel, cast iron, hard alloy, non-ferrous metals, etc. However, its brittleness is bigger, and it can not stand severe vibration, only used within the speed of 35 m/s.
Resin bond is a kind of organic bond, and this kind of grinding wheel made of resin bond has high strength, certain elasticity, low heat resistance, good self-sharpening, simple production, and short process period. It can make some grinding wheels whose working speed is higher than 50 meters/seconds and very thin grinding wheel. It is second only to the application scope of ceramic bond, widely used for coarse grinding, cutting and free grinding. It also can make high-speed and high finish grinding wheel, or other grinding wheels with heavy load and various special requirements.
