Metal coil sheet cutting to length line is one of our main machine products. We have manufactured metal sheet cut to length line machines since 2000 and have supplied them to Malaysia, KSA, UAE, Nigeria, Algeria, USA, Russia, Ethiopia, Egypt and other countries.
Coil sheets can be hot rolled, cold rolled, galvanized steel sheets, stainless steel sheet, aluminum sheets, light gauge sheet cut to length line has fine leveling and fast cutting. Sheet flatness +/-1mm per square meter, fast stop cutting 2m x 28pcs/min.
Continuous running of leveler, servo length feeding and fast pneumatic shear ensure high speed and high precision working, stacking speed follows up the coming cut sheets and stack each sheet fast one by one, for a 2mm x 1250 x 15T coil, it takes 20minutes to cut, about 40minutes one coil.
Layout
Two sets coil preparing saddle, single mandrel uncoiler with back tension, coil head press and peeler, 4 high leveler, pit loop, central guide, servo length fixing with filming, fast shear, delivery belt table, one or two sets stacker, output cars or roll tables.
Composition
- Coil saddle, store one or two coils for standby, load 20T
- Coil loading car. load coil onto uncoiler mandrel, up-down lifting and fwd-bwd walking.
- Single mandrel uncoiler: hydraulic expansion mandrel for standard Ф508mm, back tension motor is installed for stable uncoiling and leveling, centralizing uncoiler base to ensure coil center on ceterline.
- 2+15 Roller Leveler: 4Hi, 4 rows backup rollers, 75KW DC.
- 7Servo Length feeding: Servo length measuring(2+5+2 rollers driven by servo motor and controller)
- Pneumatic Fast Stop Shear: crank shaft cutting from down to up, lower blade v shape.
- Belt Conveyor: convey finished sheets to stacker
- Stacker: stacking load 5T.
- Sheets Car: deliver sheets out, then packing. can be two cars, one working and the other waiting.

Q & A
1.Q: What thickness and width range does this cut to length line cover?
A: 0.2-1.5 mm, 0.25-2.0 mm, 0.3-3.0 mm or 0.4-4.0 mm depending on the configuration, in coil widths of 600, 1000, 1250 or 1600 mm. Uncoiling load is 10, 15 or 20 t.
2.Q: How accurate is the cut length?
A: Cutting accuracy is plus or minus 0.50 mm over any 2 m length. Leveling flatness is within plus or minus 1.0 mm per square metre and cutting burr stays below 3 percent of sheet thickness, which suits downstream stamping and profiling.
3.Q: What line speed can it run?
A: Up to 80 m/min on thin gauge. Because the shear stops and starts for each cut, actual output depends on sheet length: shorter blanks mean more cycles per minute and a lower average line speed.
4.Q: What stacking accuracy does the stacker achieve?
A: Within 1.0 mm in width and 1.5 mm in length. That tolerance keeps blanks aligned for palletising or direct feeding of a press line without manual re-stacking.
5.Q: What floor space and power does it need?
A: About 25 m x 10 m of floor and 100-150 kW installed power depending on the option package. Leveler rolls and main shafts are 42CrMo hardened to HB250-275, and frames are Q235-A and Q345 (16Mn) steel.
Build standards and working accuracy
Which components and brands go into a cut to length line?
Structural parts are welded to a minimum throat of two thirds the thinner plate, shot-blasted before painting and finished with two top coats. Uncoiler, slitter and recoiler shafts are forged 42CrMo and supplied with a material certificate; gears are 20CrMnTi, case-hardened and ground. Bearings, hydraulic, pneumatic and electrical parts come from named suppliers — Yuken valves, AirTac cylinders, HIWIN linear guides, Mitsubishi or Siemens PLC, Proface HMI, OMRON sensors — and the final bill of components is fixed on the approved drawing for each line.
Which shear and leveling arrangement does the line use?
A medium gauge line uses a servo track flying shear that follows the leveling speed and cuts on the move; heavy gauge plate is leveled twice, pre-leveling and fine leveling, to relieve internal stress before shearing, and stainless or aluminium coil is edge trimmed ahead of the cut. The arrangement follows the gauge, the material and the surface the sheet has to keep.
How is the line installed and supported after delivery?
Engineers attend the customer's plant to supervise installation and train the operators on the line as built. Spare parts are supplied at any time, and remote technical support stays available for the life of the machine.
