Title How to choose the hardness of T41 green cutting wheel?
Description When using theT41 green cutting disc size, the hardness of the grinding wheel is also a problem that users often pay attention to. Because its hardness affects the effect of the cutting material, how to choose the hardness of the T41 green cutting disc grinding wheel? The hardness of the grinding wheel of the cutting disc refers to the difficulty of the abrasive disc falling off under the action of external force. In order to meet the requirements of different workpiece material grinding, the grinding wheel is divided into different hardness grades. The grinding wheel is selected too hard, the blunt abrasive grains are not easy to fall off, the grinding wheel is easy to block, the grinding heat is increased, the workpiece is easy to burn, the grinding efficiency is low, and the surface quality of the workpiece is affected; the grinding wheel is selected too soft, and the abrasive grain is also off when it is sharp. Increases the wear of the grinding wheel, easily loses the correct geometry and affects the accuracy of the workpiece. Therefore, the choice of the hardness of the grinding wheel should be appropriate, and should be considered according to the contact area of the grinding wheel and the workpiece, the shape of the workpiece, the way of grinding, the cooling method, the type of bonding agent of the grinding wheel and other factors.
