Metal service centers handle large volumes of coil stock and must deliver sheets and plates in exact sizes with tight flatness tolerances. Cut-to-length lines combine uncoiling, leveling, shearing and stacking into one continuous process, turning a mother coil into finished sheets at speeds of up to 60 meters per minute.
The heart of a modern cut-to-length line is the flying shear or rotary shear, which cuts the moving strip on the fly so that the line never has to stop. Servo-driven shears achieve length accuracy of +/-0.3 mm at high line speeds, while precision stacking systems ensure that finished sheets arrive at the pack table neatly aligned and ready for strapping.
For processors handling thick plates, heavy-duty lines use hydraulic or mechanical shears with stop-and-go operation. These machines are engineered for rigidity, with heavy frame construction and powerful leveler rolls that can flatten material up to 25 mm thick and 2,500 mm wide.
By integrating cut-to-length capability into their operations, service centers can offer just-in-time delivery of exact-size blanks, reduce their own inventory of pre-cut sheets and improve overall material yield. It is an investment that pays off through higher throughput and better customer retention.
