Cold cutting 80CrV2 steel 520mm parrot tooth circular friction saw blade
Friction circular saw blade is mainly used for cutting welded tube, and also for small steel sections, such as channel steel and angle steel, etc. in normal temperature. It is characterized by high hardness above 40HRC, good abrasive resistance of the saw body, good surface quality after cutting, and high cutting speed.
Friction saw blades are designed to cut steel tubes and profiles at very high peripheral speeds and material temperatures below 250° C. The high peripheral speed causes the workpiece to melt and the hot steel is swept out of the cut. Although the process compromises cut quality most applications prioritise cutting speed to meet the demands of high volume production.
Friction saw blades are available in both Chrome Vanadium (CrV) and Tungsten Manganese (WMn) with the option of chromium coating to extend blade life. Other customer specified special friction saw blades are available to order.
Our friction and hot saw blades are designed for cutting carbon steel in a variety of sizes and shapes. They are used in flying or stationary sawing machines for tube production lines or for cutting grating and other profiles. Optimized for an extra long blade life and no cracking diameters are available up to 48"(1200mm).
Processing operation
Laser cutting for volume production and improving saw blade quality, compare with shear and punching method which is easily lead to micro cracks, laser cutting machine minumizes this occurrence.
Heat treatment
Continuous quench system to increase hardness to request standard
Milled teeth with consistent precision, optimized to virtually no cracking
Tension testing/rolling/straightening machine
Each piece of steel core and saw blade being testing/rolling and straightening before delivery by our homemade high precision testing/rolling and straightening machine which arrurate to 0.01mm, proprietary rolling and straightening process results in highest precision and smallest side run-out.
