Vertical cold cut saw is a kind of equipment used to cut metal materials, this saw in the cutting process generates less heat, because the heat generated by the saw when cutting through the saw transferred to the sawdust, maintain the workpiece and saw blade cooling state, so the name cold cut saw. Vertical cold cut saws usually use high speed steel blades (HSS) and TCT insert alloy blades, which have different cutting speeds and tooth feed rates, suitable for different materials and specifications of the workpiece cutting. The use of vertical cold cut saw can improve the cutting efficiency, reduce the burr of the workpiece, improve the cutting accuracy, and the saw blade itself has a long service life, which can be extended by grinding
