we have two kinds of flying saw : cold flying saw and hot flying saw.This article will describe the differences between the two types of flying saws

Hot & Cold Flying Saw Cut Off Steel Pipe For Tube Mill Production Line
An excellent sawing scheme improves the quality of the workpiece, extends the sawing life of the saw blade and speeds up the sawing speed. This is the first step in the metal products industry to improve product quality, increase production efficiency and reduce production costs in the production process. What is the difference between a hot flying saw and a cold-cut flying saw? Now, Let us discuss together

Cold flying saw VS hot flying saw:
cold flying saw：At a normal temperature, the metal is rapidly cut by a circular saw blade that is rotated at a high speed, and the cut end face is flat and smooth as a mirror.
Hot flying saw: The high-speed cutting is accompanied by high temperature and spark, and the cut end face is purple and has many burrs.
cold flying saw：The high-speed steel saw blade rotates slowly and mills the welded pipe, so it can be burr-free and noise-free. The sawing process produces very little heat, and the saw blade has little pressure on the steel pipe and does not cause deformation of the pipe wall.
hot Flying saw：The hot flying saw is a high-speed rotation of the tungsten steel saw blade, and the contact welding pipe generates heat to break it, which is actually blown. High burning marks are visible on the surface. A large amount of heat is generated, and the saw blade exerts a great pressure on the steel pipe, causing quality defects in the pipe wall deformation.
cold flying saw：±1.5mm
hot Flying saw：±2.5mm
