CNC Punching
CNC Punching & Sheet-Metal Forming UK
B&Z provides precise, efficient CNC turret punching for sheet-metal parts in mild steel, stainless and aluminium. Turret tooling makes fast work of repeat holes, slots and perforations, and can add features to reduce secondary operations.
We hold tight, repeatable tolerances with clean edges and offer deburr finishing ready for bend, weld and coat. Send DXF, DWG, or PDF and we’ll return a clear price and lead time, with practical DFM advice on tool selection, minimum features and nesting.
Industries & sectors
Electronics & enclosures (vented panels, mounting patterns, knock-outs, PEM-ready holes)
Industrial machinery (guards, control panels, perforated access covers)
Architectural & interiors (perforated screens, trays, signage backers)
HVAC & building services (patterned ducts, plenums, mounting plates)
Retail & POS (perforated display panels, trays, fixture components)
Film & TV props/set work (patterned grilles, decorative perforations, custom plates)
CNC Punching Key Capabilities
| Capability | Specification |
|---|---|
| Process type | CNC turret punching |
| Max work area | Up to 2,500 × 1,250 mm with repositioning |
| Materials & thickness | Mild steel ≤3mm; Stainless ≤2 mm; Aluminium ≤4 mm |
| Typical tolerance | ±0.10–0.20 mm (material/thickness/geometry dependent) |
| Minimum feature size | Guideline: min hole ≈ 1× material thickness; small slots via nibbling |
