Advantages of Diamond Polycrystalline Composite Plates

In terms of mechanical properties:

High hardness and wear resistance: Diamond polycrystalline composite sheets have extremely high hardness, second only to natural diamond, and their wear resistance is tens of times that of hard alloys. When processing high hardness materials, it can maintain the sharpness of the cutting edge, reduce tool wear, and significantly improve processing efficiency and quality.

High strength and toughness: The hard alloy substrate provides excellent support for the diamond layer, combining the high strength of diamond with the toughness of hard alloy. When subjected to large cutting and impact forces, it is not easy to crack or break, and can adapt to complex and harsh machining environments.

In terms of processing performance:

Low friction coefficient: The friction coefficient with the processed material is low, and the cutting force generated during the cutting process is small, which can lower the cutting temperature, reduce tool wear, and improve machining accuracy and surface quality.

Good cutting performance: With sharp cutting edges and excellent cutting ability, it can achieve efficient cutting, improve machining efficiency, and reduce machining costs. It can exhibit excellent cutting performance when processing various materials such as metals, ceramics, and composite materials.

In terms of thermal performance:

High thermal conductivity: Diamond has an extremely high thermal conductivity, which can quickly dissipate the heat generated during the cutting process, effectively reducing the temperature in the cutting area, avoiding tool damage due to overheating, and improving tool durability.

Low thermal expansion coefficient: Its thermal expansion coefficient is small, and during the machining process, the tool is not easily deformed due to temperature changes. The degree of cold hardening of the machined surface is small, which is conducive to obtaining good machining accuracy and surface quality.

In terms of service life:

Good corrosion resistance: Diamond polycrystalline composite sheets have good chemical stability and are not prone to chemical reactions with the processed material during processing. They have good resistance to some corrosive working environments, thereby extending their service life.

Long service life: Taking into account its high hardness, wear resistance, high strength, toughness, and good thermal properties, diamond polycrystalline composite sheets have a long service life under normal usage conditions, reducing the frequency of replacing cutting tools or drill bits, improving work efficiency, and reducing usage costs.

In terms of economy and environmental protection:

High processing efficiency: Due to its excellent cutting performance and wear resistance, diamond polycrystalline composite sheets can achieve high-speed cutting and efficient processing, greatly reducing processing time, improving production efficiency, and thus reducing processing costs.

High material utilization rate: Its sharp cutting edge and good cutting control ability can reduce material waste, improve material utilization rate, and reduce raw material costs.
Environmental protection and energy conservation: The cutting force generated during the processing is small, the cutting temperature is low, the use of cutting fluid is reduced, the energy consumption during the processing is reduced, and the pollution to the environment is also reduced.
