ERW tube and tube cutting servo motor control single blade cold saw, cold cutting saw performance. During the metal sawing process, the heat generated by the saw blade when sawing the workpiece is transferred to the sawdust through the saw teeth, and the saw blade and the workpiece remain cooled. Cold cutting saws are different from conventional friction saws. 

The friction between the workpiece and the friction saw blade results in a high temperature of the friction saw and the workpiece. The cold cutting saw has high cross-section precision, no burr inside and outside, smooth cutting surface, no need for subsequent processing such as flat chamfering, reducing the processing strength of subsequent processes, saving time and raw materials, high temperature caused by friction does not change performance, and cutting is improved. Efficiency, no spark, no noise, environmental protection and energy saving.
