High-speed steel saw blade, also known as wind steel saw blade, white steel saw blade, is an alloy containing a large amount of carbon (C), tungsten (W), molybdenum (Mo), chromium (Cr), vanadium (V) and other elements Hacksaw blade.
High-speed steel raw materials have high hot hardness after cutting, forging, annealing, semi-finished products, quenching, toothing and other production processes. When the cutting temperature is as high as 600 ℃ or more, the hardness still does not decrease significantly, and the cutting speed of the saw blade can reach more than 60 meters per minute, hence the name of the high-speed steel saw blade.
A. Classification of high-speed hacksaw:
High-speed steel can be divided into ordinary high-speed steel and high-performance high-speed steel according to chemical composition.
According to the manufacturing process, it can be divided into smelting high-speed steel and powder metallurgy high-speed steel.
B. Correct use of high-speed hacksaw
1. For saw blades of different specifications and uses, the angle of the cutter head and the form of the base body are different, so try to use them according to their corresponding occasions;
2. The size and shape and position accuracy of the main shaft and splint of the equipment have a great influence on the use effect. Before installing the saw blade, check and adjust it. In particular, the clamping force is affected by the contact surface between the splint and the saw blade.
The factor of displacement slip must be divided;
3. Pay attention to the working conditions of the saw blade at any time, if any abnormality occurs, such as vibration, noise, and material feeding on the processing surface, it must be stopped and adjusted in time, and repaired in time to maintain peak profits;
4. The grinding saw blade shall not change its original angle to avoid local sudden heating and cooling of the blade head, it is best to ask professional grinding;
5. The saw blades that are not used temporarily should be hung vertically to avoid laying flat for a long time, and objects should not be piled on it. The cutter head should be protected and not allowed to collide.
C. Application of high-speed hacksaw blade
Ordinary high-speed hacksaws are mainly used for narrow and deep groove processing or cutting of metal materials such as steel, iron, copper, aluminum, etc. It can also be used for non-metal milling. High-performance high-speed hacksaws are mainly used for milling of difficult-to-cut materials (heat-resistant steel, stainless steel and other high-strength steels).
Features of high-speed steel saw blade: It can be repeated many times with a high-speed steel saw blade grinding machine to grind the edge teeth. Improve production efficiency and reduce costs.
Applicable machinery for high-speed steel saw blades: various domestic and imported automatic or semi-automatic and hydraulic pipe cutting machines, metal circular saws, pipe blanking machines, pipe processing machinery, sawing machine tools, milling machines, etc.
Tooth type of high-speed steel saw blade: BW tooth type is the most widely used, followed by A, B, C type teeth, and BR and VBR tooth types are used less in China.
