Introduction
Fly cutting to length panel is highly required for thin sheet metal cutting for the reasons:
1.Thin coil sheet length is long, i.g. a 0.3mm thick coil length is 10times length of 3mm coil, the faster line speed means higher weight production of cut sheets.
| Coil specification | Sheet length | Cutting line speed | Cutting time per coil | |
| 0.3mm steel coil | 508mm ID,1250mm width, 15T | ~5000m | 50m/min | 100mins |
| 3mm steel coil | 508mm ID, 1250mm width, 15T | ~500m | 50m/min | 10mins |
2.Thin sheet can be easily cut in one fast stroke, thus fly cutting is available: the sheet runs at stable speed, fly shear fast cut off a sheet while synchronously tracking the running sheet, the track cutting process takes about 0.5s, max cutting frequency can be up to 150times/min. The productivity can be linear 80m/min
3.The fly cutting is specially suitable for short sheets making, although the extremely short sheets take more time to precisely track and cut, its cutting frequency still can be around 100pcs/min.

Q & A
1.Q: Why use a flying shear instead of a stop-start shear on thin stainless?
A: Because thin coil is long: a 0.3 mm, 1250 mm wide, 15 t coil runs about 5000 m, ten times the length of a 3 mm coil. Cutting on the fly lets the line hold 50 m/min instead of stopping for every cut.
2.Q: What output does that give in practice?
A: A 0.3 mm coil of about 5000 m is cut in roughly 100 minutes at 50 m/min, while a 3 mm coil of about 500 m is finished in about 10 minutes. Sheet length, not line speed alone, sets the cycle count.
3.Q: What thickness and width does the line handle?
A: 0.3-3 mm stainless up to 1250 mm wide, with 508 mm coil inside diameter and 15 t coil weight. Other widths can be quoted on the same platform.
4.Q: Does cutting on the fly damage the sheet edge?
A: No. The shear travels with the strip during the cut, so there is no relative motion between blade and material. That is why flying shear is preferred for thin stainless, where a stop-start cut would leave marks.
5.Q: How is sheet length accuracy held at speed?
A: Length is measured by encoder on the running strip and the shear is triggered to match, so accuracy holds as line speed rises. The control compensates for the strip length change between measuring and cutting.
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.
