A Technological Study on Granite Grinding
It is desirable that the precision of the shape and the dimension of stone products in top grade decoration is getting higher. Grinding is one of the main technology in machining stone which ensures the precision of the shape and the dimension of stone products, and influences the machining efficiency. This investigation aims to experimentally find out the reasons causing grinding wheel wear and the factors influencing smoothness. It is found that the wear of grinding wheel is mainly caused by the hardness and removal quantity of stone. The harder the stone, the shorter the life of grinding wheel. The greater the removal quantity of stone, the bigger the wear of grinding wheel. The surface smoothness of stone is mainly related to the size of abrasives and the spindle speed. The smaller the abrasives and the higher the speed, the higher the smoothness.
