Tungsten carbide saw blade is the most commonly used cutting tool for wood products processing, also called TCT saw blade (Tungsten carbide tipped saw blade). The quality of carbide saw blade is closely related to the quality of processed products. Correct and reasonable selection of cemented carbide saw blades is of great significance for improving product quality, shortening processing cycle and reducing processing cost. The cemented carbide saw blade includes many parameters such as the type of alloy cutter head, the material of the substrate, the diameter, the number of teeth, the thickness, the tooth shape, the angle, and the aperture, etc. These parameters determine the processing ability and cutting performance of the saw blade. When selecting a saw blade, it is necessary to correctly select the saw blade according to the type, thickness, sawing speed, sawing direction, feeding speed, and sawing road width of the sawing material.
The commonly used types of cemented carbide are tungsten-cobalt and tungsten-titanium. Due to the better impact resistance of tungsten-cobalt cemented carbide, it is more widely used in the wood processing industry.
The commonly used models in wood processing are YG8-YG15, and the number behind YG indicates the percentage of cobalt content. As the cobalt content increases, the impact toughness and bending strength of the alloy increase, but the hardness and wear resistance decrease. Choose according to the actual situation.
- 65Mn spring steel has good elasticity and plasticity, economical material, good hardenability after heat treatment, low heating temperature, easy deformation and can be used for saw bladesthat do not require high cutting requirements.
- Carbon tool steel has high carbon content and high thermal conductivity, but its hardness and wear resistance drop sharply when subjected to a temperature of 200°C-250°C, large heat treatment deformation, poor hardenability, and long tempering time are easy to crack. Manufacturing economical materials such as T8A, T10A, T12A, etc. for knives.
- Compared with carbon tool steel, alloy tool steel has better heat resistance, wear resistance, and better processing performance. The heat-resistant deformation temperature is 300°C-400°C and is suitable for manufacturing high-grade alloy circular saw blades.
- High-speed tool steel has good hardenability, strong hardness and rigidity, and less heat-resistant deformation. It is an ultra-high-strength steel with stable thermoplasticity and is suitable for manufacturing high-grade ultra-thin saw blades
