the development of artificial wood panels in recent years have greatly contributed to the further application of PCD cutting tools. Hence, PCD cutting tools are slowly replacing the usage of traditional woodworking tools in the wood processing industry.

　　PCD cutting tools can process all kinds of wood. They can process natural wood, particleboard, medium and high-density fibreboard, to name a few. Laminate flooring is welcomed by users for its wear resistance, waterproof and moisture resistance, corrosion resistance, and easy installation. The outermost layer of Al2O3 has a great influence on the wear of cemented carbide cutting tools, but the particularity of its structure determines the special requirements for cutting tools in the machining process. PCD cutting tools can effectively solve this problem.

　　High hardness, high wear resistance, high thermal conductivity, low friction coefficient, and good tooth shape retention are the main features of PCD tools. Moreover, the cutting speed of PCD tools can reach 3000m to 5000m per minute. On top of that, the cutting capacity can also reach tens of meters per minute.

　　Types of PCD tools in wood processing industry　

　　There are two common types of PCD cutting tools in the woodworking industry, which are:

　　PCD milling cutter

　　PCD milling cutter has a lot of varieties such as floor milling cutter and furniture milling cutter.

　　Compared with a traditional milling cutter, PCD milling cutter has a larger diameter and higher rotational speed. As a result, milling accuracy is improved.

　　PCD saw insert

　　Meanwhile, PCD saw insert can produce a  better quality cutting section as it can carry out long-time, deep and ultra-high-speed cutting without stopping and grinding.

　　At present, the use of PCD woodworking circular saw blades is increasing, and it is gradually replacing the traditional carbide circular saw blades.

　　During processing, different grades of PCD composite sheets should be selected for different processing materials, rather than simply pursuing high hardness and wear resistance. Coarse-grained PCD tools are relatively more wear-resistant but are prone to chipping, while finer-grained PCD can sharpen higher-quality cutting edges, resulting in better surface finish quality and better blade toughness. When processing the Al2O3 surface strengthening layer of the laminate floor, a coarser-grained material should be selected, and a finer-grained composite sheet should be selected when processing the middle layer of the floor to improve the smoothness of the material.

　　PCD woodworking tool is an effective tool for wood machining. The specific geometric parameters of PCD tool depend on the comprehensive processing conditions of workpiece condition, tool material and structure. Because PCD tools are often used in the finishing of workpieces, the cutting thickness is small, and it is a micro cutting. Therefore, the clearance angle and the flank face have a significant impact on the machining quality. Smaller clearance angle and higher flank quality can improve PCD. The machining quality of the tool can play an important role.

　　A PCD saw blade is more expensive than carbide saw blade, but you you can imagine the benefit of using longer life, diamond tooling when it eliminates 100 tool changes that would occur if carbide tools were used. PCD tooling may be 20X the price of carbide tooling, but if it runs 50X as long, it doesn't take much time before the benefits of increased production rates and decreased downtime more than cover this cost difference.
