What is a Cut-to-Length Line in Production?

In metal processing, a cut-to-length line is used to cut metal coils into flat sheets of precise length. Especially in manufacturing processes requiring high precision and efficiency, the flat sheets produced by this cut-to-length line are often further processed by roll forming machines to transform them into various sheet materials required for the project, widely used in industries such as building steel structures, automotive chassis, and machinery manufacturing.

This cut-to-length line not only operates fully automatically but also precisely cuts sheets according to the actual project requirements of customers, ensuring the production of high-quality sheets with burr-free surfaces. Therefore, cut-to-length lines are in high demand in the market.

What is the Cut-to-Length Line Process?

The core of a cut-to-length line is to transform large metal coils (such as steel and aluminum) into flat, precisely sized sheets through a series of continuous processes. The entire process includes several key steps such as unwinding, leveling, measuring, shearing, and stacking. First, the decoiler unfolds the metal coil and feeds the material into the next process under appropriate tension. Next, the leveling machine smooths the surface of the roll material to ensure smooth subsequent processing and avoid dimensional errors caused by material curling.

After leveling, the material is precisely measured to ensure its length meets specific requirements, and then fed into the shearing machine for cutting. The shearing machine accurately cuts the material according to pre-set parameters, ultimately forming flat sheets of the required length. After shearing, the stacker stacks these cut sheets for subsequent transportation or further processing.

What Types of Cut-to-Length Lines Do You Offer?

KINGREAL STEEL SLITTER offers a variety of cut-to-length lines based on customers' actual project needs. KINGREAL STEEL SLITTER machines can process a variety of materials, including steel, stainless steel, aluminum, copper, and PPGI. To meet customers' personalized needs in terms of thickness, width, length, and cutting methods, KINGREAL STEEL SLITTER has specially developed several shearing lines in different specifications. For example, based on material thickness, KINGREAL STEEL SLITTER has specially designed cut-to-length lines for light gauge cut-to-length line (0.2-3mm), medium gauge cut-to-length line(0.3-6mm), and heavy gauge cut-to-length line (6-25mm) to ensure customers can choose the cut-to-length line best suited to their product needs.

In terms of cutting methods, KINGREAL STEEL SLITTER cut-to-length lines are also diversely designed, offering a variety of options such as fly shearing cut-to-length line, rotary shearing cut-to-length line, swing shearing cut-to-length line, and fixed shearing cut-to-length line. These different types of cut-to-length lines each have their unique advantages, meeting the specific requirements of different users in the production process.

Furthermore, KINGREAL STEEL SLITTER can equip cut-to-length lines with special components to further enhance the functionality and flexibility of the equipment. For example, equipping the cut-to-length line with a double leveler can significantly improve the leveling accuracy of the plate surface, ensuring the quality of the finished product. Additionally, configuring a double stacker in the cut-to-length line not only improves the automation level of the entire production process but also increases work efficiency, better meeting the needs of mass production. In addition, to meet customers' stringent requirements for the surface quality of the boards, KINGREAL STEEL SLITTER is also able to equip the cut-to-length lines with a laminating device to ensure that the board surface is free of scratches and maintains its perfect condition.

FAQ About Cut-to-length Line

1/How long do cut-to-length line blades last?

The lifespan of cut-to-length line blades depends on the material being cut and the frequency of use. KINGREAL STEEL SLITTER also offers custom alloy steel blades to extend service life.

2/What if the cut-to-length line breaks down?

KINGREAL STEEL SLITTER cut-to-length lines are of very reliable quality. If any parts are damaged, KINGREAL STEEL SLITTER will provide you with replacement parts.

3/What kind of tolerances can be achieved?

Tolerance of length: L=2M≤±0.3MM(2.0MM), Diagonal tolerance: L=2M≤±0.5MM(2.0MM), depending on the cut-to-length line's structure and control system.

4/How often should I inspect the blades and rollers?

You should inspect the blades and rollers every day before starting work. Weekly inspections help to identify more serious wear or alignment issues. For best results, always follow the manufacturer's maintenance schedule.

5/What is the difference between cutting and slitting?

Cutting involves dividing roll material into sheets of a specific length using a cut-to-length line. Slitting involves processing roll material into narrow strips of a specific width using a metal slitting machine.
