Saw is an indispensable tool in the production of wood, plank, raw material processing, or furniture. Today, we will talk about woodworking circular saw!



Saw, planer, drill, I believe that you readers are exposed to things every day. When you buy a saw blade, you will generally tell the seller what kind of machine is used for cutting wood plates! Then the merchants will select or recommend the saw blade for us! Have you ever thought about why a certain product must use a saw of a certain specification?, Xiaohui will talk to you
Alloy saw blades are commonly used in wood or furniture production (few machines or products! Diamond saw blades are required, which can be divided into sintered diamond saw blades, brazed diamond saw blades and electroplated diamond saw blades. I will talk about this later. Today, I will talk about the saw teeth of alloy saw blades)
You can carefully observe the sawtooth shape of the saw blade. The main tooth shapes are: left and right teeth, flat teeth, alternate teeth, trapezoidal teeth, high and low teeth, ladder flat teeth, etc. There are other saw blades with different tooth shapes, which are suitable for different objects and cutting effects.
It is trapezoidal tooth or tapered tooth. The plate is marked and grooved, and the shape of the teeth is conducive to weight loss, which is impossible, ha ha! The main trapezoidal teeth can avoid edge collapse when used in veneer!

The left and right teeth are more used on multi blade saws or cutting saws, but the number of teeth is not too dense, which affects chip removal. There are fewer teeth, and the teeth are large. The left and right teeth are also more conducive to longitudinal cutting!
Saw blades like electronic saws, push table saws, or reciprocating saws! The auxiliary saws are mostly trapezoidal teeth, and the main saws are mostly ladder flat teeth! The ladder flat teeth can not only ensure the processing quality, but also improve the efficiency of the saw! However, the grinding of saw blade is more complicated!
The denser the teeth are, the more flat and smooth the cutting surface of the sawn plate is. However, the denser the teeth are, it is not conducive to the cutting of thicker plates! The saw blade is easy to burn when cutting thick plates with close teeth sawing because the chip removal is too small!
The teeth are sparse and large, which is more conducive to the processing of raw materials! The teeth are large and sparse, and the sawn boards will have saw lines. However, there are not too many flat teeth, most of them are helical or left and right teeth, which can be avoided to some extent! It is also conducive to the grinding of the saw blade! Of course, there is one more thing to pay attention to! If the wood grain is cut crosswise, it is recommended to use a multi tooth saw blade. There is a potential safety hazard when using less teeth!
summary
For oblique cutting and cross cutting, select multiple teeth, for longitudinal cutting, select fewer teeth, and for wood grain structure, select cross cutting.

No matter what tooth type saw blade is, its quality still depends on the material of the base, the arrangement of the alloy, the processing technology, the heat treatment of the base, the dynamic balance treatment, the stress treatment, the welding technology, the angle design, the precision of the grinding, etc.

It is very important to control the feed speed and the feed speed of the saw blade to extend the service life of the saw blade. During installation and disassembly, the alloy head must be protected from damage. Some saws with precise requirements should also be repaired in time if they cannot meet the processing requirements.
