Frequently Asked Questions (Supplemental)
1) What tolerances can a Corrugated Roof Panel Roll Forming Machine hold at speed?
- With encoder-based length control and inline laser width gauges, typical cut-length ±0.5–1.0 mm and panel width ±0.7–1.0 mm are achievable at 35–60 m/min, profile- and gauge-dependent.
2) How do I minimize oil-canning and waviness in corrugated panels?
- Ensure entry leveling, maintain consistent coil tension, use progressive radii in early passes, verify roll parallelism, and limit speed on thin gauges (<0.35 mm) or deep corrugations.
3) Which cutoff system is best for coated steel and aluminum coils?
- A servo flying shear or rotary shear with carbide knives synchronized to line speed reduces burring and end deformation compared with mechanical guillotines.
4) Can one machine handle multiple corrugation pitches and depths?
- Yes, with cassette-style tooling or adjustable roll sets and HMI recipes. Expect sub-20-minute changeovers when using pre-gapped cassettes and poka-yoke alignment.
