A Cold Cutting Saw is an important cutting equipment used in ERW tube mill production lines. It is designed to cut steel tubes and pipes accurately without generating excessive heat during cutting. Compared with traditional friction saw cutting, cold saw cutting provides smoother pipe ends, lower noise, better dimensional accuracy, and cleaner cutting surfaces.

Cold cutting saws are widely used in carbon steel tube production, structural pipe manufacturing, furniture tube production, construction materials, automotive tubing, and many other industries requiring high-quality pipe cutting.

What Is a Cold Cutting Saw?

A Cold Cutting Saw, also called a Flying Cold Saw or Tube Mill Cold Saw, is an automatic pipe cutting machine installed at the end section of an ERW tube mill line.

Its main function is to continuously cut welded steel tubes into preset lengths while the tube mill is running at high speed.

Unlike friction saws that cut material through high-speed friction and heat, a cold saw uses a carbide saw blade rotating at controlled speed to perform precision cutting with minimal heat generation. This is why it is called “cold cutting”.

The result is:

• ✔️Smooth pipe end surface

• ✔️Minimal burrs

• ✔️High cutting accuracy

• ✔️Low deformation

• ✔️Reduced noise and sparks

• ✔️Better finished pipe quality

Position of Cold Cutting Saw in ERW Tube Mill

The pipe enters the cold saw continuously, and the flying saw synchronizes its moving speed with the pipe speed to perform non-stop cutting.

Typical process flow:

Uncoiler → Accumulator → Forming Section → HF Welder → Cooling → Sizing → Straightening → Cold Cutting Saw → Run Out Table

This flying cutting method ensures continuous production without stopping the tube mill.

Working Principle of Cold Cutting Saw

The cold cutting saw operates using a servo synchronization control system.

During production:

1. The steel tube moves continuously from the tube mill.
2. The flying saw carriage accelerates and synchronizes with tube speed.
3. The carbide circular saw blade rotates and cuts the pipe precisely.
4. After cutting, the saw carriage returns automatically to its original position.
5. The next cutting cycle begins immediately.

Modern cold saw systems usually adopt:

• Servo motor control
• PLC automatic control system
• High precision encoder tracking
• Automatic length measurement
• Intelligent synchronization technology

These systems help maintain stable cutting accuracy even at high production speeds.

Main Advantages of Cold Cutting Saw

High Cutting Accuracy

Cold saws can achieve very accurate pipe length tolerance, suitable for high-standard industrial tube production.

Smooth Pipe Ends

The carbide blade produces clean and smooth cutting surfaces with very small burrs.

Lower Noise and Sparks

Compared with friction saws, cold cutting generates much less noise and almost no sparks.

Better Surface Quality

The pipe end does not overheat or discolor easily during cutting.

Suitable for High-Speed Production

Flying cold saw systems can match modern high-speed ERW tube mills efficiently.

Cold Cutting Saw Technical Parameters

⚠️Parameters can be customized according to tube mill requirements.

Cold Cutting Saw vs Friction Saw

In modern ERW tube mill lines, cold cutting saws are becoming increasingly popular because customers demand higher pipe quality and cleaner cutting results.

FAQ

What blade does a cold cutting saw use❓

Cold cutting saws usually use TCT carbide saw blades or HSS saw blades for precise, efficient, and durable metal pipe cutting.

Is cold cutting saw suitable for stainless steel tubes❓

Yes. Different blade materials and configurations can be selected for stainless steel applications.

What is the difference between flying cold saw and stop cutting❓

Flying cold saw cuts tubes while the production line continues running, while stop cutting requires stopping the tube movement during cutting.

Which is better: cold saw or friction saw❓

It depends on production requirements. Cold saw is better for high precision and smooth pipe ends, while friction saw is more economical for general production.

Can the cutting length be adjusted automatically❓

Yes. Modern cold saw systems support automatic length setting through PLC control.
