What Is a Flying Shear in a Cut to Length Line?

Flying shear, also called flying cut, is a cutting system used in cut to length line where the shear unit moves synchronously with the metal strip during cutting.

Unlike traditional stop shear systems, where the strip must stop completely before cutting, flying shear:

• Acceleartes to match the strip speed
• Performs cutting while moving forward
• Returns to the initial position after cutting

Because the shear "flies" with the strip, this method allows continuous or semi-continuous strip feeding, reducing production downtime and improving line efficiency.

 

How Does a Flying Shear Cut to Length Line Work?

The basic  process of flying shear cut to length lien includes:

1. Metal coil is uncoiled, leveled and fed forward
2. Length measuring system detects the preset sheet length
3. Flying shear unit moves forward at strip speed
4. Shear performs the cut while moving
5. After cutting, shear returns to its start position
6. Strip continues feeding to next cut

This type of synchronized cutting motion reduces mechanical shock and vibration, ensuring smooth operation and longer equipment life.

 

Key Advantages of Flying Shear Technology

1. Higher Production Efficiency

Since the strip does not need to stop for each cut, flying shear cut to length line acheives:

• Higher average line speed
• Shorter cycle time
• Improved output for medium and thick coils

This makes flying shear ideal for medium-duty cut to length line

 

2. Suitable for Medium and Thick Metal Coils

Flying shear is commonly used for processing:

• Carbon steel
• Hot rolled steel
• Galvanized steel
• Medium to thick stainless steel

It is especially suitable for coil thickness above thin-gauge ranges, where rotary shear is not optimal.

 

3. Reduced Mechanical Stress and Wear

Compared with stop shear system, flying shear:

• Reduces sudden acceleration and deceleration
• Minimizes impact force on the strip
• Extends the service life of critical mechanical components

This results in lower maintenance costs and improved long-term stability.

 

Typical Applications of Flying Shear Cut to Length Lines

Flying shear cut to length lines are widely used in:

• Steel service centers
• Construction and structural steel processing
• Shipbuilding and heavy equipment manufacturing
• Plate processing for machinery fabrication

Any application requiring stable cutting of medium metal sheets can benefit from flying shear system.

FAQ: Flying Shear Cut to Length Line

Q1: Is flying shear for thin metal coils?

A: Of course flying shear is also no problem for cutting thin metal coils. But if you need a high speed solution we will prefer to suggest rotary shear cut to length line to you.

Q2: Does flying shear affect cutting accuracy?

A: No. With proper synchronization and control, flying shear provides excellent length accuracy and clean edge quality.
