1. Outer diameter of saw blade
The outer diameter of the saw blade should be according to the limit of the machine installation of the saw blade and the thickness of the cutting material, the small diameter has 110mm, the large diameter of the saw blade can reach 450mm and above, the installation of the saw blade needs to be installed up and down at the same time, or left and right at the same time, so that without increasing the diameter of the saw blade, the cutting thickness of the saw machine can be improved.
2. Number of saw blade teeth
Too many saw blade teeth will produce resistance to the machine when cutting, so the number of teeth in the design of the saw blade is relatively small, such as the outer diameter of 110-180mm saw blade, the number of teeth is only about 12-30, the diameter of more than 200 is only about 30-40 teeth, of course, if the machine power is large, and the cutting effect is required to be good, you can use the saw blade with more teeth.
3. Saw blade scraper
The scraper is welded cemented carbide on the saw blade matrix, which can be divided into internal scraper, external scraper and tooth scraper. The inner scraper is used to cut hardwood, the outer scraper is used to cut wet wood, and the tooth scraper is generally used for trimming. The scraper can improve the cutting effect, reduce the burning of the saw blade, and increase the chip removal capacity, reduce the number of grinding times, and make the saw blade last longer.
4. Saw blade aperture
The aperture of the saw blade should be selected according to the requirements of the machine, multi-blade saw is to install multiple pieces together, in order to ensure stability, the aperture is generally larger than the conventional saw blade, like the saw blade with an outer diameter of 110-200mm, the aperture should be between 35-40mm, the aperture of the saw blade of 230-300mm is between 40-70mm, and the saw blade with an outer diameter of 300mm or more, the aperture should be less than 50mm.
5. Saw blade thickness
Generally, we hope that the thinner the saw blade, the better, the thickness of the alloy saw blade will be determined by the manufacturing material and process, if the thickness is too thin, it is easy to shake when cutting. Therefore, the thickness of the saw blade should be selected from the stability and the material of the saw, and the deeper the sawing application of the thicker saw blade improves the stability of the saw blade, and will not burn out due to the saw blade swing burning.
6. Tooth shape of the saw
The tooth shape of the saw blade is all alternating left and right teeth, but there are also saw blades with a smaller diameter designed as flat teeth.
7. Saw blade coating
Saw blade coating is mainly to improve the beauty of the saw blade, generally after welding or polishing, the coating treatment is carried out, covering the welding and pulling marks, and improving the beauty of the saw blade. ...
