How to choose the right saw blade according to the parameters of woodworking saw blade

Woodworking saw blade is the most commonly used tool for wood products processing, but not all wood products are processed with the same woodworking saw blade. As the saying goes, each lock corresponds to only one key, so different wood needs different woodworking saw blades. There are many parameters involved in woodworking saw blades, such as the choice of alloy type, matrix, diameter, number of teeth, thickness and so on. Next, let Bian Xiao tell you how to apply these parameters correctly and reasonably to choose the right woodworking saw blade.

The first is the choice of alloy type. Commonly used cemented carbide types are tungsten cobalt (code YG) and tungsten titanium (code YT). Tungsten-cobalt cemented carbide is widely used in wood processing industry because of its good impact resistance. The commonly used model in wood processing is YG8-YG 15, and the number after YG indicates the percentage of cobalt content. With the increase of cobalt content, the impact toughness and bending strength of the alloy increase, but the hardness and wear resistance decrease, so it should be selected according to the actual situation.

Then the choice of diameter, the diameter of the saw blade is related to the sawing equipment used and the thickness of the sawing workpiece. The diameter of saw blade is small, and the cutting speed is relatively low; The diameter of saw blade is large, which has high requirements for saw blade and sawing equipment and high sawing efficiency. Choose the outer diameter of the saw blade according to different circular saw models. ? The diameters of standard parts are110mm (4 inches),150mm (6 inches),180mm (7 inches), 200mm (8 inches), 230mm (9 inches) and 250mm (/. 450 mm (18 inch), 500 mm (20 inch), etc. The diameter of woodworking saw blades is mostly designed between 120 mm and 400 mm.

Secondly, the choice of the number of teeth. Generally speaking, the more teeth, the more cutting edges per unit time, and the better cutting performance. However, when the number of teeth is more, the number of cemented carbide is more, and the price of saw blade is higher. However, if the teeth are too dense, the amount of chips between the teeth will be smaller, which will easily cause the saw blade to heat up. In addition, if there are too many serrations, if the feed is not properly matched, the cutting amount per tooth is very small, which will aggravate the friction between the cutting edge and the workpiece and affect the service life of the cutting edge. Generally, the tooth pitch is 15-25mm, and the reasonable number of teeth should be selected according to the sawing material.

The choice of woodworking saw blade needs to be referenced from many parameters. In addition to the above mentioned parameters, there are some others, such as thickness selection, tooth profile selection, aperture selection and so on. These parameters determine the machining ability and cutting ability of the saw blade. The choice of woodworking saw blade has a great influence on your work efficiency and work effect, and has a great influence on improving product quality and shortening working hours. The above is the method of how to choose the right woodworking saw blade compiled by Bian Xiao for you.
