CNC sheet metal fabrication in Gujarat works best when cutting and forming live under one roof — and that is exactly how Layer X runs its Satellite, Ahmedabad workshop. We take flat stock to finished, folded part in a single facility: a 3 kW fibre laser that cuts mild steel up to around 20 mm, feeding directly into a 160-tonne CNC press brake with a 3,200 mm bed. No transport between a cutting vendor and a bending vendor, no tolerance stack-up from parts crossing town, and one team accountable for the whole job. Because we hold AS9100 Rev D, ISO 13485:2016, and ISO 9001:2015, every fabricated part can carry a CMM report and full material traceability. Quotes come back within 24 hours, there is no minimum order, and standard lead time is 3–5 days. This guide covers laser capability, press-brake limits, tolerances, and how to specify a job that runs clean the first time.
Key Takeaways
- Layer X delivers CNC sheet metal fabrication in Gujarat as a single-source service — 3 kW fibre laser cutting straight into 160 T press-brake forming.
- The fibre laser cuts mild steel to ~20 mm, plus stainless, aluminium, brass, and copper, with clean, near-dross-free edges.
- The 160-tonne press brake with a 3,200 mm bed folds long, heavy parts to ±0.5° on well-specified bends.
- Every fabricated part can ship with a CMM report and full material traceability under AS9100, ISO 13485, and ISO 9001.
- 24-hour quotes, no minimum order, and a 3–5 day standard lead time.
Why single-source laser-to-press-brake wins
The biggest hidden cost in sheet metal work is not machine time — it is the hand-off between a company that cuts and a different company that bends. Every transfer adds days, a re-clamping datum, and a finger to point when a flange lands out of tolerance. Consolidating both operations is the core of how we approach CNC sheet metal fabrication.
- One datum — parts are cut and folded referencing the same edges, so tolerances do not stack across vendors.
- Faster turnaround — no courier days lost shuttling blanks between a cutting shop and a bending shop.
- Single accountability — one team owns cut, bend, and final dimensions.
- Design feedback early — the person quoting the laser also flags bends that will collide or crack.
A control-panel client came to us after their split cut-and-bend supply chain kept producing enclosures with misaligned mounting holes. Cutting and forming the parts in-house on our CNC sheet metal fabrication line brought hole-to-bend position back inside ±0.3 mm and cut two days off every batch.
Fibre laser cutting: 3 kW capability
Our fibre laser is the front end of any sheet metal fabrication job. At 3 kW it cuts a wide envelope of metals with a narrow kerf and a clean, near-dross-free edge that usually needs no secondary finishing before bending. Fibre sources also handle reflective metals — aluminium, brass, copper — that older CO₂ machines struggle with, and they run at a fraction of the energy cost per metre. Cut-edge quality is graded by ISO 9013, and a well-set 3 kW source routinely holds its finer perpendicularity and roughness ranges on mild steel, so parts arrive at the press brake ready to fold rather than needing a linishing pass first. See the full fibre laser cutting service for current bed size and nesting options.
| Material | Practical max thickness (3 kW) | Typical use |
|---|---|---|
| Mild steel | ~20 mm | Brackets, base plates, frames |
| Stainless steel | ~12 mm | Medical, food, enclosures |
| Aluminium | ~10 mm | Lightweight panels, heatsinks |
| Brass / copper | ~6 mm | Bus bars, electrical, décor |
- Tight nesting to make the most of every sheet and cut material cost.
- Clean edges that feed straight into forming without deburring on most gauges.
- Repeatable contours for holes, slots, and logos down to fine detail.
CNC press-brake bending: 160 T, 3,200 mm bed
Once a blank is cut, it moves to the press brake — a 160-tonne machine with a 3,200 mm bed, sized to fold long enclosure walls and thick brackets that smaller shops have to sub-contract. Tonnage and bed length set the outer limits of what CNC sheet metal fabrication can form in a single hit, and 160 tonnes across 3.2 metres covers the large majority of structural and enclosure work in one setup.
Good bend design keeps parts both cheap and accurate:
- Keep the inside bend radius at least equal to material thickness to avoid cracking.
- Allow a minimum flange length of roughly four times thickness so the metal seats on the die.
- Keep holes and slots at least 2.5× thickness away from a bend line, or they distort.
- Standardise bend angles — every unique tool change adds setup cost.
ISO 2768-1 class "m" (medium) permits ±0.3 mm on nominal dimensions between 30 mm and 120 mm — the default tolerance band most sheet-metal drawings rely on, and one our press brake holds comfortably on well-specified bends.
Materials, thickness, and tolerances
Matching material, thickness, and tolerance to the job is where a fabrication quote is won or lost. Over-specifying a tight tolerance on a non-critical edge, or a thick gauge where a rib would do, quietly inflates cost. Our team reviews every drawing for exactly this before quoting sheet metal fabrication work, and will suggest the cheaper equivalent wherever it does not cost you function.
| Feature | Typical achievable tolerance | Notes |
|---|---|---|
| Laser-cut profile | ±0.1 mm | On gauges up to ~6 mm |
| Hole position | ±0.1–0.2 mm | Cut in the same setup |
| Bend angle | ±0.5° | Per bend, well-specified |
| Formed length | ±0.3 mm | Per ISO 2768-m |
A few defaults we recommend on every drawing:
- Use ISO 2768-m general tolerances unless a feature genuinely needs finer.
- Call out only the two or three dimensions that are truly critical.
- Specify grain direction only when bends risk cracking on hard tempers.
Quality, lead time, and traceability
Speed means little without proof the part is right, which is why certification sits at the centre of our CNC sheet metal fabrication. Every job can close with a CMM dimensional report checked against your drawing, plus full material traceability linking the finished part back to its mill certificate and batch. Standard lead time is 3–5 working days, and every enquiry is quoted within 24 hours with no minimum order.
AS9100 Rev D requires documented traceability of materials and processes throughout the supply chain — the discipline that lets a fabricated bracket be audited back to its source coil years after it shipped.
For an aerospace ground-support client we cut, folded, and CMM-verified a run of 3 mm stainless brackets, delivering each with a dimensional report and material certificate as one traceable package. That single-source, documented workflow — laser to press brake to inspection — is what regulated buyers in Gujarat and beyond come to us for. Send a drawing to our Ahmedabad workshop to get started.
Frequently Asked Questions
What thickness can your CNC sheet metal fabrication handle?
Our 3 kW fibre laser cuts mild steel up to around 20 mm, stainless to about 12 mm, and aluminium to roughly 10 mm. The 160-tonne press brake then forms those blanks, with the 3,200 mm bed handling long parts in a single bend sequence.
Do you offer both laser cutting and bending in-house?
Yes. Single-source laser-to-press-brake is the core of our sheet metal fabrication in Gujarat — cutting and forming happen in the same Ahmedabad facility, so there is no tolerance stack-up or courier delay between separate vendors.
What tolerances can you hold on formed parts?
Laser-cut profiles hold about ±0.1 mm and bend angles about ±0.5° on well-specified geometry, in line with ISO 2768-m. Critical features are verified on a CMM and reported against your drawing.
How fast can I get a quote and parts?
Quotes come back within 24 hours of receiving your DXF or STEP file, with no minimum order. Standard lead time for CNC sheet metal fabrication is 3–5 working days depending on quantity and finishing.
