With the development trend of the use of automated machine tools such as automatic machine tools to replace the traditional manual operation method, it has higher requirements for polycrystalline diamond compact. What are the features of polycrystalline diamond compact? 1. Has high hardness. The hardness of polychen diamond is HV7500~9000, second only to natural diamond. And its hardness and abrasion resistance are the same as the same sex without choice. The strength of its strength can reach 1500 mPa due to high tough alloy support, composite bending strength.
2. Has high abrasion resistance. The wear resistance of polychen diamond is higher than hard alloy. When non -metallic materials with higher hardness, durability is extremely high.
3. Have a lower friction factor. The number of friction factor between polycrystalline diamond and non -ferrous metals is 0.1 ~ 0.3, while the friction factor of hard alloy and non -ferrous metal is 0.3 ~ 0.6.
4. It has high thermal conductivity, which can greatly reduce the temperature of the cutting area and increase the durability of the tool.
5. Small expansion coefficient.
6. You can make various sizes and shapes as needed.
7. Superior toughness and impact resistance.
