Metal cold saw or metal cold saw cutting, is the metal circular saw machine saw cutting process abbreviation. In the process of metal sawing, the heat generated by the saw blade saw cutting workpiece is transferred to the sawdust through the saw blade, and the workpiece and saw blade are kept cool, hence the name cold sawing. Cold saw cutting and friction saw different, the latter workpiece and friction saw friction, in the process of cutting friction saw and workpiece temperature is very high. Cold cutting saw workpiece precision, no burr, reduce the processing strength of the next process; The workpiece will not change the material due to the high temperature caused by friction; Low fatigue of operators, providing sawing efficiency; No spark, no dust, no noise; Environmental protection and energy saving. It can be used for sawing ordinary steel pipe and profile, and for sawing stainless steel pipe and profile. Sawing is faster and more efficient. Low deflection of saw blade can improve the cutting precision of workpiece.
