Computer-controlled production

CNC processes selected by feature, tolerance, and batch economics

CNC sheet metal fabrication is a coordinated digital workflow across cutting, punching, forming, and inspection, not a synonym for CNC machining.

Capability Fabex scope Engineering checkpoint
CNC equipment 15 CNC machines, including four 6 kW laser cutters and 10 press brakes Publish machine data only where it helps buyers understand a real production constraint.
Work envelope Matched to sheet size, flat pattern, and formed geometry A flat pattern that fits cutting equipment may still exceed forming access.
Repeatability and tolerance Consistent production quality supported by controlled procedures and precision CNC equipment Do not apply one tolerance claim to every cut, bend, hole, and assembly feature.
Digital workflow CAD review, CAM programming, nesting, revision-controlled release, and inspection planning Programs and inspection points should be linked to the released model and drawing revision.
Inspection evidence First-article inspection before production, weekly production updates, and image, video, or livestream reports available Critical features need a measurable method, not only a general quality statement.

Not sure whether your part fits this capability?

Send your drawing, material, quantity, and delivery target. Our team will review the process route, manufacturability risks, and open questions before quotation.

Digital thread

From CAD interpretation to a repeatable released program

The goal is a stable process package that can reproduce the same approved part revision.

1

Model and drawing reconciliation

Resolve conflicts between 3D geometry, 2D tolerances, material, finish, and hardware callouts.

Checkpoint

Released manufacturing input has one authoritative revision.

2

CAM and nesting

Select the process, create machine programs, plan common-line or efficient nesting, and preserve feature intent.

Checkpoint

Program output reviewed for edge quality, grain, marking, and heat effects.

3

Forming and in-process checks

Use the bend sequence, tooling plan, and first-off measurements to control accumulated variation.

Checkpoint

Critical features checked before the full batch proceeds.

4

Inspection and program retention

Inspect the agreed features and retain the approved program, setup, and revision for repeat orders.

Checkpoint

Inspection records trace back to the released job.

What changes your quoted cost

  • Material utilization and nesting
  • Cut or punch cycle time
  • Number of setups and tool changes
  • Bend sequence complexity
  • Inspection and reporting requirements
  • Material grade and thickness

How we plan your project

Repeatable CNC batch production

See the commercial and engineering checkpoints Fabex uses to move this type of job from drawing review into controlled production.

CNC sheet metal production equipment

Application

Automation, electronics, displays, electrical and power equipment, solar, and new-energy products

Material

SPCC, SGCC, SECC, aluminum 5052, SUS304, and other drawing-specified grades

Quantity

CNC process questions

CNC sheet metal fabrication FAQs

Answers that separate sheet metal process control from subtractive CNC machining.

Which CNC processes are used for sheet metal fabrication?+

Depending on the drawing, the route may use CNC laser cutting, turret punching, press-brake bending, and programmed inspection. CNC machining is quoted only when a genuinely machined feature or separate machined part is required.

Do you need both a 3D model and a 2D drawing?+

A 3D model improves programming and geometry review; a 2D drawing should define tolerances, critical dimensions, material, finish, threads, hardware, and inspection requirements. Conflicts are resolved before release.

Can the same CNC program be reused for repeat orders?+

The approved program and setup can be retained, but each repeat order should still confirm drawing revision, material, quantity, and any process or equipment change.

How are tolerances assigned across cutting and bending?+

Tolerance capability depends on the process and feature relationship. Cut-feature accuracy, bend angle, flange length, and dimensions crossing multiple bends should be reviewed separately.

How do you prevent the wrong revision from reaching production?+

A controlled release should tie the customer file revision to the job traveler, CNC program, bend setup, and inspection record. Superseded files are removed from the active production package.

When should secondary machining be added to a sheet metal part?+

Secondary machining may be appropriate for precision bores, sealing faces, deep threads, counterbores, or datums that cutting and forming cannot control economically. The added setup should be limited to features that genuinely require it.

Engineering before production

Three DFM checks that prevent expensive revisions

A useful fabrication quote begins with the manufacturing route, critical interfaces and realistic tolerances, not only a CAD model.

View the complete sheet metal DFM guide
01

Control the critical features

Apply tight tolerances only to datums, mating features and functions that need them. Process and size govern what is practical; unnecessary precision adds setups, inspection, cost and lead time.

02

Reduce setup changes

Standardize bend radii, hole sizes, hardware and material thickness wherever the design permits.

03

Plan the full route

Check cutting, bending, welding, finishing, inspection and assembly access before releasing the drawing.

Customer Perspective

Trust is earned in the next order

B2B customers often give brief, practical feedback and show their trust through the next project.

Selected customers

  • Huawei
  • vivo
  • Sunglow

Full production programs, repeat orders, and multi-year supply — not one-off samples. References available for your sector on request.

Trust shown through repeat work

In contract manufacturing, the clearest reward is often another drawing, another production order, or a larger scope.

Confidential by default

We do not publish a customer's name, product, drawing or project details without written permission. That is not a lack of proof - it is how contract manufacturing works, and it is the same discretion we apply to your designs.
