Stone engraving machine cutting tool materials is very important

Stone carving machine tool material is very important, so it must be have some performance, then what are they? Stone carving machine tool material is carved stone and the use of cutting tools is important one annulus, generally have cutting tool material performance is as follows: 1, high hardness and wear resistance; Hardness is the basic characteristic of the cutting tool material should have, the cutting tool to cut off from the workpiece material, its hardness must be bigger than the hardness of workpiece material. Cutting tool material hardness is generally in more than 60 HRC. Wear resistance is the ability to materials resistant to wear and tear, under normal circumstances, the cutting tool material the higher hardness, wear resistance, the better, material grain more fine, distribution more uniform, the higher wear resistance. 2, enough strength and toughness; To make the cutting tool under a lot of pressure, and in the cutting process under the working conditions of shock and vibration and does not produce collapse and broken blade, cutting tool material, you must have enough strength and toughness. 3, high heat resistance; Refers to keep cutting tool materials in high temperature hardness, wear resistance, strength and toughness properties. Cutting tool material of high temperature hardness is higher, the better the performance of the tool cutting, allowing the higher the cutting speed also; In addition to the high temperature hardness, cutting tool material should also has the ability of oxidation resistance at high temperature and good bonding and diffusion resistance ability. 4, good process performance; For ease of manufacture, required cutting tool material has good process performance. 5, economy; Economy is one of the important indicators of cutting tool materials. Although some cutting tool materials is very expensive, but because of its long life, contribution to the cost of each part is not necessarily very high. 6, the predictability of cutting performance. With the development of the processing automation, tool wear and tool life, such as cutting performance with good predictability. So we want to buy stone carving machine tool to consider above points, according to their own raw material hardness and cost to choose the right tool.
