First, the type of saw blade
1. According to the materials used: high-speed steel saw blade (HSS saw blade), solid carbide saw blade, tungsten steel saw blade, toothed alloy saw blade, diamond saw blade, etc.
2. According to the use: milling cutter saw blade, machine saw blade, manual saw blade, special saw blade (aluminum saw blade, copper cutting saw blade, stainless steel saw blade, etc.), pipe cutting saw blade, wood saw blade, stone saw blade, cut acrylic saw blade, etc.
3. According to the surface coating: white hacksaw blade (natural color), nitriding saw blade (black), titanium plated saw blade (gold), chromium nitride (color), etc.
4. There are also some other names: cutting saw blade, cutting saw blade, grooving saw blade, cut saw blade, integral saw blade, tooth saw blade, ultra-thin saw blade.
Second, the diameter of the saw blade is small, and the cutting speed is relatively low; The large diameter of the saw blade means that the cutting speed is relatively high, and the requirements for the saw blade and sawing equipment are correspondingly high. THE DIAMETER OF STANDARD PARTS IS: 110MM (4 INCHES), 150MM (6 INCHES), 180MM (7 INCHES), 200MM (8 INCHES), 230MM (9 INCHES), 20MM (10 INCHES), 300MM (12 INCHES), 350MM (14 INCHES), 400MM (16 INCHES), 450MM (18 INCHES), 500MM (20 INCHES), etc., THE BOTTOM GROOVE SAW BLADE OF THE PRECISION PANEL CUTTING SAW IS MOSTLY DESIGNED TO BE 120MM.
Third, generally speaking, the more teeth, the better the cutting performance, but the more cemented carbide is needed, the cost is high, and the sawteeth are too dense, which is easy to cause the saw blade to heat; In addition, excessive serrations will also aggravate the friction between the cutting edge and the workpiece, affecting the service life of the cutting edge. Usually the tooth spacing is 15-25mm, and a reasonable number of teeth should be selected according to the material sawn.
Fourth, we want the saw blade to be as thin as possible, and saw seams are actually a consumation. The material of the alloy saw blade matrix and the process of manufacturing the saw blade determine the thickness of the saw blade, the thickness is too thin, and the saw blade is easy to shake when working, which affects the cutting effect. When selecting the thickness of the saw blade, it should be considered from the stability of the saw blade work and the material sawed. The thickness required by some special purpose materials is also specific and should be used according to equipment requirements.
