How to choose a stone engraving machine to engrave granite?

The stone engraving machine tools on the market are uneven and the price difference is large. I hope this article can provide some help and suggestions for customers on the issue of purchasing tools. The following are the following suggestions for customers according to the characteristics of stone engraving machines. 1. Pay attention to the high hardness and wear resistance of the stone carving tool: hardness is the basic characteristics of the stone tool material should have, the tool to cut the material from the workpiece, its hardness must be greater than the hardness of the workpiece material. The hardness of cutting tool materials is generally above 60HRC. Wear resistance is the ability of the material to resist wear, in general, the higher the hardness of the tool material, the better the wear resistance, the finer the grain of the material, the more uniform the distribution, the higher the wear resistance. 2. Pay attention to the strength and toughness of stone tools: to make the tools work under great pressure and under the conditions of impact and vibration in the cutting process without chipping and breaking, tool materials must have sufficient strength and toughness. 3. High heat resistance of stone carving tools: refers to the performance of tool materials to maintain hardness, wear resistance, strength and toughness at high temperatures. The higher the high temperature hardness of the tool material, the better the cutting performance of the tool and the higher the allowable cutting speed; In addition to high temperature hardness, the tool material should also have the ability to resist oxidation at high temperature and good resistance to adhesion and diffusion. 4. Economy of cutting tools: Economy is one of the important indexes of cutting tool materials. Although some cutting tool materials are very expensive, due to their long service life, the cost allocated to each part is not necessarily high. 5. Predictability of technological performance and cutting performance of cutting tools: in order to facilitate manufacturing, cutting tool materials are required to have good technological performance. With the development of machining automation, good predictability is required for cutting performance such as tool wear and tool durability. The above expression is the key point of selecting knives for stone engraving machines. A good CNC stone engraving machine must also select the right tools to better process and produce. Especially for hard materials such as carved granite, tool selection is very important.
