In order to ensure fast operation, bear the cutting impact of wood or composite materials, and maintain the ability to work for a long time, woodworking tools are mostly made of metal, but the high hardness, high strength, and high toughness of the tools must be ensured, and economical considerations must also be taken into consideration. Cost, woodworking tools are made of a variety of materials, and the cutting part and the cutter body part are compounded by welding or clamping.
Most woodworking tools are made of alloy tool steel. Some alloy elements are added to the steel to improve the toughness, hardness, wear resistance, etc. of the tool. In general, everyone should consider the most important factors first. Here are some materials used in woodworking tools.
Alloy steel
Adding trace amounts of alloy elements to steel to make alloy tool steel. In recent years, alloy tool steel has been widely used in the production of woodworking and other cutting tools.
Carbon steel
Carbon steel has low cost, good cutting ability, good thermoplasticity and is very sharp. It is an excellent material for making woodworking tools. However, this material also has shortcomings, that is, poor heat resistance. Its operating environment is required to be below 300 degrees. If the temperature is too high, the hardness of the material will decrease and the quality of the cutting operation will decrease. High-quality, high-grade steels with higher carbon content are often used to make knives used in instruments.
High speed steel
Because high-speed steel increases the proportion of alloy elements in alloy steel, it has higher thermal hardness and wear resistance, making it higher quality than carbon steel and alloy steel. The working environment of high-speed steel has been raised to about 540 degrees to 600 degrees.
Carbide
It is mainly made of metal carbides and alloy elements mixed and fired. It has the advantages of heat resistance and high hardness. It can still continue to work at about 800 degrees to 1000 degrees, and its hardness exceeds that of carbon. steel. Carbide is currently mainly used in the automated production processes of artificial panels and wood processing. However, carbide materials are relatively brittle and easy to break, so they cannot be sharpened too sharply.
Diamond
The diamond used in tool manufacturing is artificially synthesized, but the chemical structure of the two is the same. Its strength and toughness are stronger than natural diamond, but its hardness is weaker than natural diamond. Compared with other materials, it is more heat-resistant, wear-resistant and has a longer service life. Diamond composite blades are tools commonly used in woodworking for cutting laminate floors, solid wood composite floors, bamboo floors, solid wood doors, etc.
In order to meet the needs of some welding, cutting, grinding and other processing processes and ensure the performance stability of manual or machine use, the materials used in woodworking tools are not single factors, but are comprehensive and mutually restrictive. Sometimes with different quota changes, the knives produced will vary greatly.
