1. High hardness and wear resistance; Hardness is a fundamental characteristic that carving tool materials should possess. In order for the tool to cut material from the workpiece, its hardness must be greater than that of the workpiece material. The hardness of tool materials is generally above 60HRC. Wear resistance is the ability of a material to resist wear. Generally, the higher the hardness of the tool material, the better the wear resistance. The finer and more evenly distributed the material grains, the higher the wear resistance.
2. Sufficient strength and toughness; In order for the tool to work under high pressure, as well as under conditions of impact and vibration during the cutting process, without producing chipping or breakage, the tool material must have sufficient strength and toughness.
3. High heat resistance; The performance of tool materials in maintaining 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, tool materials should also have the ability to resist oxidation at high temperatures, as well as good resistance to bonding and diffusion.
4. Good process performance; For ease of manufacturing, it is required that the tool material has good processability. Common problems and solutions for various carving tools
5. Economy; Economy is one of the important indicators of tool materials. Some cutting tool materials may be expensive, but due to their long lifespan, the cost allocated to each component may not be very high.
6. Predictability of cutting performance. With the development of machining automation, it is required that cutting performance such as tool wear and tool durability have good predictability.
