The differences between various flying saws

After Roughly straightening, Then the machine cut the pipe.Both the cold cutting saws and computer-cutting saws are used to cut pipes. Let’s introduce their advantages and disadvantages. And through this article, you will know which cutting saw are suitable for you.
Computer-controlled cutting saws cut saws through high-speed friction. The saw blades rubs against the steel pipe during high-speed friction to generate high temperature molten material to achieve cutting. Computer-controlled cutting saw is simple structure , low initial investment(especially suitable for small and medium-sized steel pipes, easy to operate. Burrs or oxide layers often remain on the cut of the surface. High temperature may cause thin wall thickness pipe to deform and affect dimensional accuracy. High speed sawing is prone to spark, metal dust and noise (over 100dB) and there is risk of splinters flying, so strict protective measures are required. Suitable for scenes with limited budgets or low requirements for cut quality (such as building scaffolding pipes).

cold cutting saw is based on the principle of cold milling. Carbide saw blades are used to cut materials at a controllable speed and feed rate, similar to milling in mechanical processing. Using servo systems to achieve synchronous movement of the saw blades and steel pipe. In the cutting process, the temperature is low and there is no heat-affect zone, which avoid material changes. The saw blades has a long life, which can be reused. Also energy consumption is reduced more over 50%. With no burrs inside and outside, the incision is smooth. And this pipe can be directly used in high precision scenes, such as automotive oil pipe, medical equipment pipe, eliminating subsequent processing. Also dry cut and trace cooling methods reduce the pollution; no sparks, no noises(less than 80 dB), the saw blades is evenly stressed and has low risk of breakage. 

Here is the comprehensive table.
The selection suggestions are as follows:
Precision and material orientation:
If the pipes are used in precision machinery, cold cutting saw is must; Ordinary structural pipe can choose computer-controlled cutting saw to reduce cost.
Environment compliance:
When it is necessary to comply with standards, such as ISO 14001, the low pollution characteristic of cold cutting saw make it easier to meet the standard.
