The cold flying saw is to online cut continuous tubes into single tube based on certain length. That runs with less noise and dust. And cutting face keeps at ambient temperature, without high-temperature melting or thermal deforming. Also, cutting face has no burrs without secondary processing.
1. Precision cutting: Cutting face is smooth without burrs. And it removes heat-affected zone and tube end collapse. That almost doesn’t need chamfering.
2. Less noise: There isn’t hot cutting spark or heavy dust. And noise is significantly reduced.
