1. Definition
An 8 m CNC folder with slitter is a long-sheet clamp-and-flip folder: hydraulic upper/lower clamps hold the blank; a parallelogram hinge flips the folding beam for multi-angle bends (max about 125°). A dedicated slitting head cuts arbitrary widths.
Public CNC folder/slitter pages describe the same class for flashings, ridges, and long architectural trim — not a roll-forming mill and not a guillotine shear.
2. How it works
- Load and align the blank on the table
- Hydraulic clamps hold the sheet
- Folding beam flips to the programmed angle (up to ~125°)
- Optional longitudinal slit with the slitter head (~0.8 m/s class)
- Unload / next bend
3. Technical parameters
| Item | Reference (8 m tech note) |
|---|---|
| Max fold length | ~8000 mm |
| Max fold angle | ~125° (min workpiece angle ~55°) |
| Thickness (steel / soft Al / SS) | ~1.5 mm (yield ≤250 MPa) / ~2.0 mm / ~1.0 mm |
| Slitting thickness | Same family as fold (steel ~1.5 / Al ~2.0 / SS ~1.0) |
| Slitting speed | ~0.8 m/s |
| Throat depth | ~800 mm |
| Min flange | ~10 mm (<1.2 mm thick) or ~20 mm (≥1.2 mm) |
| Max fold cycle | ~12 s |
| Hydraulic / total power | ~7.5 kW / ~8 kW |
| Weight / outline | ~4500 kg; ~8938 × 1842 × 1375 mm |
4. Length variants
The same multi-folder pack also lists 6 m and 8 m folder/slitter quotations. Select length by contract; do not merge 6 m and 8 m into one rating. Market pages may show different slit speeds or hydraulic kW — keep this page on the 8 m technical-note band.
5. Related machines
- 4 m × 6 mm press-brake class (FOLDER-4M6) — different mechanism and force table
- 63T × 3200 NC press brake — short-table hydraulic brake, not clamp-and-flip folder
- Shear / folder packages — often inquired together; specify each unit separately
- Roof-panel roll formers — continuous coil profiling, not blank folding
6. Applications
- Long multi-angle folds for trim, flashing, ridge, and similar sheet work
- Any-width longitudinal slit on the same machine class
7. Inquiry checklist
- Fold length (6 m vs 8 m)
- Material grade and thickness (steel / Al / SS)
- Max bend angle and min flange needs
- Whether the slitter head is required
- Confirm not a press-brake or roll-former RFQ
8. Buyer FAQ
Is this a roll-forming line?
No. It is a CNC folder/slitter — blank clamp, flip bend, and slit — not continuous coil roll forming.
Can I order 6 m from the same family?
Yes as a length option in the multi-folder pack, but keep 6 m and 8 m parameters on separate proposals.
Does it need dedicated dies for 125°?
The reference design reaches the max bend angle without custom dies; confirm control software and options on the contract.
Same as a 63T×3200 press brake?
No. Force, table class, and bending mechanism are different equipment families.
Final ratings follow the named proposal. Price and lead time are out of scope.
