The stone engraving machine tools on the market are uneven, and the prices vary greatly. I hope this article can provide customers with some help and suggestions on the issue of purchasing props. The following suggestions are given to our customers based on the characteristics of the stone engraving machine.
1. Pay attention to the high hardness and wear resistance of stone carving tools:
Hardness is the basic characteristic that the stone tool material should have. The tool must cut the material from the workpiece, and its hardness must be greater than the hardness of the workpiece material. The hardness of the tool material is generally above 60HRC. Wear resistance is the ability of a material to resist wear. In general, the higher the hardness of the tool material, the better the wear resistance. The finer the material grains and the more uniform the distribution, the higher the wear resistance.
2. Pay attention to the strength and toughness of stone cutters:
In order for the tool to work under conditions of high pressure and impact and vibration during the cutting process without chipping and breaking, the tool material 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 the high temperature hardness, the tool material should also have the ability to resist oxidation at high temperatures and have good resistance to adhesion and diffusion Ability.
4. The economy of the tool:
Economy is one of the important indicators of tool materials. Although some tool materials are expensive, because of their long life, the cost allocated to each part is not necessarily high.
5. The predictability of the tool's technological performance and cutting performance:
In order to facilitate manufacturing, the tool material is required to have good process performance. With the development of machining automation, cutting performances such as tool wear and tool durability are required to have good predictability.
What is stated above is the key points of selecting a stone engraving machine. For a good CNC stone engraving machine, you must also choose the right cutter to better process and produce. Especially for hard materials such as engraving granite, the choice of knives is very important.
