Folder Machine vs Guillotine Shear in This Pack
Table of Contents
1. Definition
In the shear/folder pack, a folder (press brake) and a guillotine / swing-beam shear are standalone sheet-metal machines, not stations of one roll-forming line. The folder bends with punch and die; the shear cuts straight blanks with opposing blades. Industry fab guides use the same one-line distinction: brake bends, shear cuts.
Buyers often inquire as a pair for a workshop. Still answer tonnage/bed for the folder and cut capacity/blade gap for the shear — never one combined “line speed.”
2. What each machine does
| Machine | Primary job | Key specs to lock | Not this |
|---|---|---|---|
| Folder / press brake | Bend angles, channels, flanges | Nominal force, bed length, throat, stroke, CNC | Not coil-to-profile roll forming |
| Shear (swing beam / guillotine class) | Straight cut to width/length | Max MS/SS thickness, cutting length, strokes/min, blade gap | Not a CTL cut-to-length coil line |
- Workshop blanking + bending for flashings, brackets, and general fab
- Often paired on the same RFQ; parameters remain machine-specific
3. Pack reference machines (do not merge)
| Item | 200T×4000 folder | 6×4000 NC shear (E21S) |
|---|---|---|
| Capability headline | ~2000 kN; table ~4000 mm; ~6 mm class title | MS ~6 mm / SS ~3 mm; cut width ~4100 mm; ~10–12 spm |
| Main motor | ~15 kW | ~7.5 kW (+ backgauge servo ~0.85 kW) |
| Geometry | Throat ~320 mm; stroke ~200 mm; open height ~400 mm | Shear angle ~1°30′; throat ~120 mm; table height ~850 mm |
| Envelope / mass | ~4400×1900×2750 mm; ~13 000 kg | ~4800×1800×2250 mm; ~7500 kg |
| Conflict notes | List-row bed wording may say 200T×3200 while parameter table is 4000 mm — confirm bed length on contract | Header may show 10×4100 model text beside 6×4000 quote — align model name with capacity table |
Also see the smaller 63T×3200 folder class — different force / table / motor; do not merge with 200T×4000.
4. Boundaries
- Neither machine is a roll-forming host or a coil CTL line
- Do not publish folder tonnage as shear capacity
- Do not invent a forming-line m/min for either standalone
- Industry “guillotine vs swing beam” nuance: this pack’s shear FAQ is hydraulic swing-beam NC — still a cutting machine, not a brake
5. Inquiry checklist
- Folder: force class, bed length, NC level, tooling
- Shear: MS/SS thickness, cut length, SPM, blade gap
- Confirm whether both machines are required on the same RFQ
- Do not ask for a shared “line speed”
6. Buyer FAQ
Can one machine replace the other?
No. Cutting blanks does not create bend angles; bending does not square-cut large sheets efficiently.
Why do RFQs bundle them?
Workshop workflow: shear blanks → brake forms. Bundling is commercial convenience, not a shared parameter set.
Is this the cut-off on a roof roll former?
No. Roof-line hydraulic shears are part of a forming host. These pack machines are freestanding fab tools.
Same as the 63T×3200 folder page?
No. 200T×4000 and 63T×3200 are different force / table classes — keep tables separate.
Ratings follow the confirmed technical proposal. Commercial quotes and lead time are out of scope.
