  High-speed circular sawHow to choose the number of teeth?

  The number of teeth on a high-speed circular saw generally means that the more teeth there are, the more cutting edges there are within a unit of time, resulting in better cutting performance. However, with more cutting teeth, there are more hard alloy teeth, leading to higher saw blade prices. If the teeth are too dense, the amount of debris between the teeth is smaller, which can easily generate heat in the saw blade. Additionally, if there are too many teeth and the feed is not matched properly, the cutting amount per tooth is small, which can increase friction between the cutting edge and the workpiece, thus affecting the lifespan of the blade. Generally, the tooth spacing is between 15-25mm, and the appropriate number of teeth should be chosen based on the material of the saw.

  How to choose the thickness of a high-speed circular saw?

  The thickness of a high-speed circular saw blade is theoretically hoped to be as thin as possible, but in practice, the saw is consumable. The material of the alloy saw blade base and the process of making the saw blade determine its thickness. If the thickness is too thin, the saw blade can easily wobble during operation, affecting the cutting effect. When choosing the thickness of the saw blade, consider the stability of the saw blade during operation and the material of the saw blade. Certain special applications require specific thicknesses, so use according to equipment requirements, such as groove saw blades, dashed saw blades, etc.

  High-speed circular sawHow to choose the tooth shape?

  Common tooth shapes include left and right teeth (replaceable teeth), flat teeth, step teeth (high and low teeth), inverted trapezoidal teeth (inverted conical teeth), soft Mickey (high teeth), and less common industrial-grade left and right flat teeth.

  1. Left and right teeth are the most widely used, with fast cutting speeds and relatively simple grinding. They are suitable for various soft and hard solid wood, density boards, multilayer boards, particle boards, etc. Left and right teeth with reverse equal force protection are soft-tailed and suitable for longitudinal cutting of wood boards with various knots. Left and right saw blades with negative front angles are usually used for panel sawing because the teeth are sharp and the cutting is good.

  2. Flat teeth saws are coarser, with slower cutting speeds and the simplest grinding. They are mainly used for cutting ordinary wood, are low-cost, and are mainly used for small diameter aluminum saw blades, reducing adhesion during cutting, or using groove saw blades to keep the bottom of the groove flat.

  3. Trapezoidal teeth are a combination of trapezoidal teeth and regular teeth, with more complex wear. They can reduce the cracking of veneers during sawing and are suitable for various single and double veneer boards and fireproof boards. Aluminum saw blades often use saw blades with more teeth on the ladder to prevent adhesion.

  4. Stair teeth are commonly used on wood board saw blades. When sawing double veneer boards, the groove saw adjusts the thickness to complete the processing of the bottom groove, and then the main saw completes the cutting of the board to prevent the saw blade from collapsing.

  High-speed circular sawThe types of alloy tips, the material of the base, diameter, number of teeth, thickness, saw teeth, angles, hole diameter, and a series of parameters are combined as a whole for hard alloy saw blades. Reasonable selection and matching are necessary to better utilize their advantages.
