Cut to length line is essential machine in coil processing, designed to level, measure, and shear metal coils into flat sheets of piece lengths. Whether you're in automotive, construction, or appliance manufacturing, a CTL line can help improve production efficiency and sheet quality. In this guide, we'll explain how a cut to length line works, its key components, benefits, and answer common questions customers oftern asked.
What is a cut to length line?
A cut to length line is an automated system that processes metal coils into flat sheets of fixed lengths. It involves the following steps:
-
Uncoiling – Coil is loaded onto a decoiler.
-
Leveling – Material is flattened using precision levelers.
-
Measuring – Sheet length is measured by encoder or laser sensors.
-
Shearing – Sheets are cut to the programmed length.
-
Stacking – Finished sheets are stacked and ready for packaging or downstream use.
How does a cut to length line work?
The machine operates with PLC-based automation. An operator inputs the desired sheet length and quantity via HMI. As the coil feeds through the leveler, an encoder tracks the exact length. Once it reaches the target, a high-speed rotary shear or flying shear makes a clean cut.
For high-volume production, an automatic stacker and lifting platform are often included.
Benefits of using a cut to length line:
-
High Precision – ±0.5mm length accuracy.
-
Perfect Flatness – Hydraulic or servo levelers ensure zero residual stress.
-
Fast Production – Rotary Shear Speeds up to 80m/min for thin coils.
-
Versatility – Works with steel, stainless steel, aluminum, copper, and more.
-
Labor Saving – Full automation reduces operator workload.
