Many stone decoration and stone monument processing are made of granite. However, many stone engraving machine friends do not like to engrave such hard materials. Among all the stone types, granite is a very high hardness data. Generally, some hardness data such as marble, sandstone, bluestone and artificial stone are engraved. I want to say that I want to sculpt the granite. Don't think that he has a high hardness. In fact, choosing a reasonable tool and setting reasonable parameters is the same as carving a low-hardness material.
So when choosing a tool, choose a tool with better density and strength. High-hardness diamond tools or high-density diamond tools are good choices. When using diamond tools, ensure the high speed of the spindle. The hardness and density of the granite are relatively high, generally set at 2000 rpm. For the corundum cutter, you must choose the kind of inner layer, otherwise it will not wear, and the corundum cutter must ensure the timely supply of cooling water. The water flow should be as large as possible, and the area sprayed on the cutter head. Be as big as possible. This kind of silicon carbide tool will burn out quickly if the cooling water can't keep up.
