High Frequency Welded ERW Tube Mill Cold Saw - China Suppliers & Factory for Precision Cutting Solutions
Product Description
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.

The difference between flying saw and cold saw
| Comparison Dimensions | Computerized Saw (Hot Cutting Saw) | Cold Cutting Saw |
|---|---|---|
| Core Principle: Friction Cutting | A high-speed rotating saw blade (mostly tungsten steel) generates high temperatures through friction, "burning" through the welded pipe. | Cold milling: Using a lower speed and higher feed rate, metal is cut off like a milling cutter, resulting in a lower temperature rise during the process. |
| Cutting effect | The end face has oxidation discoloration (blue-purple), large burrs, and the tube opening is easily deformed. | The end face is flat and smooth, burr-free, and does not deform, and usually requires no secondary processing. |
| Process characteristics | High speed, high temperature, large sparks, loud noise, and smoke. | Low speed, low temperature, virtually no sparks, low noise, more environmentally friendly and safer |
| Equipment and Costs | The structure is relatively simple, and the initial investment is low; the saw blade has a low cost but wears out quickly. | The equipment is complex (servo-controlled) and requires a high initial investment; specialized saw blades are expensive but have a long lifespan and can be resharpened multiple times. |
| Production efficiency | While it offers fast single-cutting speed, subsequent deburring and other processes are required, impacting overall efficiency. | While the single cutting time is slightly longer, the high quality of the cut eliminates the need for subsequent processes, resulting in high overall efficiency. |
How to choose flying saw?
In summary, the choice between these two types of equipment mainly depends on your production needs and requirements for pipe quality:
In short, if you prioritize pipe quality and long-term benefits, a cold saw should be used; if you prioritize the lowest initial investment and don't have high requirements for the appearance of the pipe ends, a computer-controlled saw remains an economical choice.
If you can provide the specific production materials (such as carbon steel or stainless steel) and the specific requirements for the cut, I can provide you with a more detailed analysis.

Frequently Asked Questions
What is a cold cutting saw and how does it work?
A cold cutting saw is based on the principle of cold milling. It uses carbide saw blades to cut metal materials at a controlled speed and feed rate. This mechanical milling process generates very little heat, keeping the temperature low and preventing a heat-affected zone on the cut edges.
What are the main advantages of using a cold saw over a traditional flying saw?
Cold saws provide flat, smooth, and burr-free incisions that do not deform, eliminating the need for secondary processing. Additionally, they operate quietly (under 80 dB), generate no sparks or smoke, and save over 50% in energy consumption.
Does a cold saw require secondary processing for high-precision applications?
No. Because the cut is completely smooth and free of internal or external burrs, the pipes can be directly used in high-precision industries such as automotive oil pipes and medical equipment pipes, without any subsequent deburring or finishing.
Why is the initial investment for a cold saw higher than a computerized hot saw?
Cold saws utilize advanced, complex servo systems to synchronize the movement of the blade with the moving steel pipe. They also require specialized, high-quality carbide blades. However, these blades have a long lifespan and can be resharpened multiple times, lowering long-term costs.
How does a cold cutting saw reduce environmental pollution?
A cold cutting saw uses dry cutting and trace cooling methods instead of heavy chemical coolants, which minimizes environmental pollution. The process also generates no sparks and operates with low noise levels (under 80 dB).
When should I choose a computerized hot saw instead of a cold saw?
A computerized hot saw (friction saw) is an economical choice if you prioritize a lower initial equipment investment and do not have strict requirements for the appearance or oxidation discoloration of the pipe ends.
