Abrasives of grinding wheels

There are many kinds of grinding wheels, each has its own different applications, manufacturing processes and binders are also different, so each kind of grinding wheel will have its own characteristics and different applications. Next, let’s make some explanations for the abrasive of the high quality 9“ grinding wheel.


Abrasive is the most important indicator of the high quality 9“ grinding wheel, grinding wheel grinding things is to rely on it, without it is tantamount to no grinding wheel this product. The choice of abrasive is more stringent. The temperature of the grinding wheel is very high when it rubs with the workpiece. The abrasive cannot stand that high temperature and will melt away soon. Therefore, high-temperature resistance is necessary.


Many grinding products are metal, some are very hard, and abrasive hardness is not high, reverse grinding, high quality 9“ grinding wheel hardness requirements are relatively high; grinding time between the wheel and the workpiece is not instantaneous completion is required to take a certain amount of time, so it requires a strong toughness.


From the above several characteristics we can probably know what kind of high quality 9“ grinding wheel abrasive choice is: diamond, corundum, silicon nitride and so on, these materials are the world’s hardest several, they have a strong wear resistance, high-temperature resistance, and the corresponding toughness. Various kinds of grinding wheels are produced through different binding agents and manufacturing processes.
