At present, Poly-Crystal Diamond (PCD) has become the primary material used by tool manufacturers when developing tools for woodworking applications. Utilizing the unparalleled hardness and wear resistance of diamond, poly-crystal diamond can effectively improve productivity and performance, reducing the use of traditional carbide tools.
Poly-crystal diamond is composed of diamond particles with extremely high hardness, providing excellent anti-wear and anti-tear properties. The lifespan of poly-crystal diamond materials and tools is 10 to 100 times that of carbide. They can effortlessly cut wear-resistant materials like medium-density fiberboard and laminates, prevent chipping, and ensure edge integrity.
The hardness of poly-crystal diamond minimizes the chipping and brittleness of materials such as medium-density fiberboard and particleboard, which is crucial for maintaining the integrity and aesthetics of the parts. This also helps in producing woodworking tools that last longer than those made of tungsten carbide. Poly-crystal diamond can also prevent chipping and delamination in medium-density fiberboard, melamine board, and laminates, ensuring excellent surface finish without the need to replace tools. Due to the reduced frequency of tool replacements and better chip resistance, the hardness of poly-crystal diamond is a key factor in improving the performance and productivity of woodworking tools.
During woodworking, a significant amount of heat and friction is generated between the tool and the material being cut, with dense materials like medium-density fiberboard and wear-resistant materials like laminates generating the most heat and friction.
These high temperatures can cause woodworking tools to soften, thermally expand, burn edges, discolor, and fuzz, negatively affecting the lifespan and cutting performance of the tools.
Poly-crystal diamond has very high heat resistance, and some intrinsic properties of diamond make it an excellent thermal conductor. As a tool material, one fundamental property of poly-crystal diamond is its outstanding thermal conductivity. The thermal conductivity of poly-crystal diamond allows it to effectively dissipate heat, helping to prevent tool performance degradation. This means that even during prolonged use, the tool maintains consistent performance and achieves more precise and cleaner cuts. While steel and carbide also have good heat resistance, they tend to lose sharpness more easily, reducing performance and increasing the likelihood of breakage.
By reducing the amount of heat generated, poly-crystal diamond can prevent the edges of medium-density fiberboard from scorching or burning, enhancing the safety of woodworking tools. This helps limit exposure to harmful fumes, minimizes unnecessary brown discoloration and fuzzing, especially when processing at faster feed rates and cutting speeds.
In a fast-paced world, mass production, speed, efficiency, and precision are essential. For tool manufacturers, choosing the right material to meet the stringent demands of woodworking tools is crucial, and poly-crystal diamond is undoubtedly the best choice.
