PCD, short for Polycrystalline Diamond, is a material made by sintering diamond micro-powder through a special process. As the name suggests, PCD cutting tools are tools with PCD as the tool material.
The hardness of PCD cutting tools is remarkable, with a hardness value that can reach 8000 HV, which is 8 to 12 times that of carbide tools. Imagine processing materials with such a hard tool—that would be like "cutting through iron as if it were mud". This high hardness not only allows PCD cutting tools to maintain a sharp edge during processing but also effectively resists material wear, extending the tool's service life.
PCD cutting tools also have outstanding compressive strength, meaning they are not easily deformed or fractured under pressure. This is incredibly important for fields requiring high-precision processing because if the tool is deformed or broken, the processed product will be ruined. The high compressive strength of PCD cutting tools ensures the stability and reliability of the processing. Good thermal conductivity is another highlight of PCD cutting tools. PCD has a thermal conductivity of up to 700 W/mK, which is 1.5 to 9 times higher than that of carbide and even higher than that of PCBN and copper. This means that during processing, PCD cutting tools can quickly transfer heat away, preventing the tool from being damaged by overheating. Additionally, good thermal conductivity can reduce thermal deformation during processing, thereby improving machining accuracy.
Due to their high hardness and good thermal conductivity, PCD cutting tools can maintain a sharp and intact edge for a long time during processing and are not easily worn. This is undoubtedly a huge advantage for fields requiring long continuous processing.
The characteristics of PCD cutting tools make them widely used in many processing fields. For example, in the machining of mobile phone lenses, acrylic lenses, LED LCD panels, appliance panels, and other products, PCD cutting tools play a significant role. These products demand very high machining precision and surface finish, and PCD cutting tools can precisely meet these requirements.
In mobile phone lens processing, PCD cutting tools can easily achieve high-precision cutting and chamfering while ensuring the surface smoothness of the lens. PCD cutting tools can guarantee that the processed lenses are as smooth as a mirror, making them very appealing. In the processing of acrylic lenses, PCD cutting tools also perform exceptionally. Acrylic lenses are widely used in advertising, decoration, lighting, and other fields, requiring high machining precision and surface finish. PCD cutting tools can easily handle these challenges, producing acrylic lenses with high precision, good surface finish, and high production efficiency.
LED LCD panel and appliance panel processing also cannot do without PCD cutting tools. These products require extensive cutting and chamfering operations during processing, and PCD cutting tools can ensure high precision and efficiency for these operations. Additionally, the high wear resistance of PCD cutting tools makes them widely used in these fields. Severe tool wear would require frequent replacements, affecting production efficiency and increasing production costs. However, PCD cutting tools can maintain sharpness and integrity for a long time, reducing replacement frequency and lowering production costs.
PCD cutting tools are also essential in high-end manufacturing fields like aerospace, automotive manufacturing, and medical devices. These sectors demand extremely high processing precision and efficiency, and PCD cutting tools can meet these requirements, providing strong support for high-end manufacturing. The success of PCD cutting tools in these fields is attributed not only to their performance advantages but also to ongoing innovation and development.
