Metal cold sawing or metal cold sawing is the abbreviation of metal circular sawing process. English full name: Circular Cold Sawing In the process of metal sawing, the heat generated by the saw blade sawing the workpiece is transferred to the sawdust through the sawtooth, and the sawed workpiece and the saw blade are kept cool, hence the name cold sawing.
There are 2 types of Cold Saw Blade:
High Speed Steel Cold Cutting Saw Blade
High Speed Steel Cold Cutting Saw Blade
High Speed Steel Saw Blades (HSS) and TCT Teeth Alloy Saw Blades
The materials of high-speed steel saw blades are mainly M2, M35. The general sawing speed of the saw blade is between 10-150 m/s, depending on the material and specifications of the workpiece to be sawed; for the coated high-speed steel saw blade, the sawing speed can be adjusted. up to 250 m/min. The tooth feed of the saw blade is between 0.03-0.15 mm/tooth, depending on the power, torque and quality of the saw blade.
The outer diameter of the saw blade is 50-650 mm; the hardness of the saw blade is HRC 65; the saw blade can be ground, depending on the specifications of the sawing workpiece, it can generally be ground 15-20 times. The sawing life of the saw blade is 0.3-1 square meters (the area of the end face of the sawing workpiece) is larger than the high-speed steel saw blade specification; the insert high-speed steel is generally used (more than 2000 mm); the sawtooth is made of insert high-speed steel. The substrate of the sheet is vanadium steel or manganese steel.
The material of the TCT tooth alloy is tungsten steel; the general sawing speed of the saw blade is between 60-380 m/s, depending on the material and specification of the sawing workpiece; the tooth feed of the tungsten steel saw blade is between 0.04-0.08 .
High Speed Steel Cold Saw – Partial
High Speed Steel Cold Saw – Partial
Saw blade specifications: 250-780 mm; there are 2 types of TCT saw blades for cutting iron, one is small tooth, thin saw blade, high sawing speed, long saw blade life, about 15-50 square meters; it is a throwaway saw One is large tooth, the saw blade is thick, the sawing speed is low, and it is suitable for sawing large-sized workpieces; the diameter of the saw blade can reach more than 2000 mm. The life of the saw blade is generally about 8 square meters, and it can be ground 5-10 times.
But the specific scorpion is determined according to your cutting material and equipment
