Definition of CR Cut To Length Line
KINGREAL SLITTING CR cut to length line can process cold-rolled materials with thicknesses ranging from 0.3 mm to 3 mm. It cuts coils into metal sheets ranging from 500 mm to 6000 mm or even longer, according to the production needs of different industries, and stacks them neatly. It is fully adaptable to the production standards of small and medium-sized processing enterprises and large-scale mass production plants.
KINGREAL SLITTING provides reliable and durable integrated CR cut to length machine solutions for the metal processing industry. The entire CR cut to length line adopts an integrated design, incorporating four core functions: precision leveling, servo feeding, precise shearing, and automatic stacking, achieving efficient and high-quality automated production. The high-quality cold-rolled sheets produced by the CR cut to length machine possess excellent surface quality, strictly controllable dimensional tolerances, and higher structural strength. They are highly precise and stable, and are widely used in industries such as automotive, home appliances, construction, and precision metal processing. They are perfectly compatible with subsequent deep processing steps such as bending, stamping, and assembly.

Features of CR Cut To Length Line
Hydraulic or electric uncoiler, equipped with a trolley.
The CR cut to length line offers a choice of professional hydraulic or electric decoilers to accommodate cold-rolled steel coils of different weights and specifications. Combined with a dedicated loading trolley, it enables rapid coil loading and automatic positioning, eliminating the need for intensive manual handling.
Precision leveling machine for correcting sheet flatness.
The multi-roller leveling machine on the CR cut to length machine precisely corrects defects such as warping, wrinkles, and wavy edges in cold-rolled coils, completely eliminating internal stress and ensuring that the sheets processed by the CR cut to length line meet flatness standards, with a smooth and deformation-free surface.
High-speed cut-to-length machine for precise cutting.
The CR cut to length machine is equipped with a high-speed cut-to-length machine, with an optimized shearing process for 0.3-3mm thin cold-rolled sheets. The shearing blade is sharp and wear-resistant, with uniform force distribution, resulting in a smooth and vibration-free cutting process, eliminating problems such as burrs, chipping, and dimensional deviations.
Heavy-duty stacker for neat sheet stacking.
The CR cut to length line features a heavy-duty automatic stacker that automatically adjusts the stacking position according to the length and specifications of the sheets. After cutting, the finished sheets are automatically conveyed and neatly stacked, resulting in a dense, flat, and highly aligned stack. No manual handling is required, facilitating sheet storage, transportation, and warehousing.
Optional side trimming device for edge cutting.
For high-end processing scenarios with extremely high requirements for the flatness and uniformity of sheet metal edges, the cold-rolled shearing line supports an optional side trimming device. This device automatically trims excess edges and corners on both sides of the sheet metal, removing burrs and defects, resulting in uniformly neat edges.
Equipped with a servo drive for precise speed and length control.
The CR cut to length machine uses a high-quality servo drive, which can precisely control the equipment's operating speed and the sheet metal cutting length, meeting the fixed-length cutting needs of 500mm to 6000mm and extra-long custom-made sheets, adapting to flexible production needs with multiple specifications and high precision.
Advantages of Cold-Rolled Sheets
Cold-rolled sheets processed by the KINGREAL SLITTING CR cut to length line have the following advantages:
Higher Strength: After being shaped by the cold rolling process and precisely processed by the CR cut to length machine, cold-rolled sheets have approximately 20% higher strength than hot-rolled steel, stronger structural stability, and excellent resistance to compression and deformation, making them suitable for various high-stress, high-load component applications.
Higher Precision: Utilizing servo-controlled precision sizing and leveling technology on the CR cut to length line, the cold-rolled sheets achieve precise dimensions and stable flatness after forming, with strictly controllable dimensional tolerances. Finished products require no frequent calibration or trimming.
Smooth Surface: The cold-rolled sheets have a bright and smooth surface, free from rust, oxide scale, scratches, and other defects. Processed on the CR cut to length machine, there is no secondary damage, making it an ideal substrate for high-end surface treatments such as spraying, electroplating, and lamination.
Good Ductility: Cold-rolled sheets possess excellent plasticity and uniform, stable material properties. After processing on the CR cut to length line, the internal stress of the sheet is uniform, making it suitable for medium-stretching, bending, and stamping forming processes, and less prone to cracking and deformation.
Cold-rolled Sheet vs. Hot-rolled Sheet
Cold-rolled and hot-rolled sheet materials differ significantly in processing technology, finished product performance, and application scenarios. Precise matching of CR and HR cut to length lines maximizes the application value of both types of sheet materials, accurately matching the needs of different industries:
Hot-rolled sheet material
Hot-rolled sheet material boasts high toughness and outstanding load-bearing capacity, but its surface finish and dimensional accuracy are relatively limited. It is commonly used in building structures, bridges, ships, pressure vessels, and structural steel—fields requiring high toughness and load-bearing capacity but low surface quality requirements. A conventional HR cut to length line can meet its production needs.
Cold-rolled sheet material
Cold-rolled sheet material, with its core advantages of high precision, high surface finish, and high strength, is widely used in automotive bodies, appliance housings, precision instruments, and hardware components—fields with high requirements for surface finish, dimensional accuracy, and strength. It must rely on the precision shearing and leveling processes of a CR cut to length line to ensure that the finished product meets high-end industry standards.
Ps: KINGREAL SLITTING can also provide HR cut to length lines according to customer needs.
