The Main Characteristics Of PDC Cutter
The main characteristics of the polycrystalline diamond composite cutter are as follows:
1) Has extremely high hardness. The hardness of polycrystalline diamond is HV7500~9000, second only to natural diamond. Its strength is supported by tungsten carbide with higher toughness, and its composite bending strength can reach 1500MPa.
2) It has high abrasion resistance. The wear resistance of polycrystalline diamond is generally 60 to 80 times that of tungsten carbide. When cutting non-metallic materials with high hardness (>HV1500), the durability is extremely high.
3) Has a lower friction factor. The friction factor between polycrystalline diamond and non-ferrous metals is 0.1~0.3, while the friction factor between tungsten carbide and non-ferrous metals is 0.3~0.6. PCD tools made of polycrystalline diamond (PCD) materials can reduce cutting force and cutting temperature by about 1/2 to 1/3 compared with tungsten carbide tools.
4) It has high thermal conductivity. The thermal conductivity of polycrystalline diamond is 1.5-7 times that of tungsten carbide, which can greatly reduce the temperature of the cutting zone and improve the durability of the tool.
5) Has a small expansion coefficient. The coefficient of linear expansion of polycrystalline diamond is very small, about 1/10 of that of ordinary steel. In addition, because the blade is sharp, the work hardening degree of the machined surface is only about 1/3 of that of the tungsten carbide tool, so the machining accuracy is good.
6) It can be made into various sizes and shapes as required.
7) It exhibits significantly superior toughness and impact resistance than single crystal diamond, which makes up for the shortcomings of single crystal diamond that is brittle and easy to cleavage to a certain extent.
