High Frequency Welded ERW Tube Mill Cold Saw - Reliable 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 advantage of cold saw
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.
Compared to flying saw, the incision is smooth with no burrs inside and outside. 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 (FAQ)
What is the core working principle of a cold cutting saw?
A cold cutting saw operates on the principle of cold milling. It uses carbide saw blades to cut metal pipes at a controlled speed and feed rate, keeping temperatures low to avoid creating a heat-affected zone.
Does a cold saw produce burrs during the cutting process?
No, unlike hot friction saws, a cold saw produces smooth, flat, and burr-free incisions. This eliminates the need for secondary deburring and allows the pipes to be used directly in high-precision applications.
Can the saw blades of a cold cutting saw be reused?
Yes, the carbide saw blades have a long service life and can be resharpened and reused multiple times, significantly lowering long-term consumable costs.
How much energy does a cold cutting saw save?
A cold cutting saw can reduce energy consumption by more than 50% compared to traditional hot cutting processes, making it a highly energy-efficient choice.
How do I choose between a computer-controlled hot saw and a cold saw?
If you prioritize high-quality cuts, lack of burrs, and long-term efficiency, a cold saw is the ideal choice. If your priority is a lower initial equipment investment and you do not require high-quality end finishes, a computerized hot saw remains an option.
