Keep the hardness just right. When we choose wearresisting grinding media ball, often be the hardness problem of the grinding media the hardness, not the bigger the better, is the appropriate hardness value. Simply put, the higher the hardness, the greater the impact reaction during the process of falling, increasing the ball loss.
Dec 15, 2000· The grinding wheel is one component in an engineered system consisting of wheel, machine tool, work material and operational factors. Each factor affects all the others. Accordingly, the shop that wants to optimize grinding performance will choose the grinding wheel best suited to all of these other components of the process.
A with the exception of heat–treated wire of diameter .100" ( mm) and larger, the Rockwell Hardness Test is not recommended for round wire. On such heat–treated wire the specimen shall be flatten on two parallel sides by grinding. For round wire the Tensile Strength Test is greatly preferred to the Rockwell Hardness Test.
