- CNC Punching
High-speed CNC turret punching for holes, slots, louvres, and formed sheet-metal.
- Service Overview
CNC turret punching is Kurveline’s process for sheet metal components that require repetitive hole patterns, slots, louvres, or formed features. The TRUMPF TruePunch 100 holds multiple punch and die sets in a rotating turret, enabling punching, forming, and embossing of complex sheet patterns without tool changes between operations. It is faster and more economical than laser cutting for high-volume repetitive pattern work.
Kurveline punches sheet metal components in MS and SS 304/316 — ventilation panels, mounting plates, enclosure fronts, perforated shelving, louvre grilles, and formed tab features for assembly.
- High-speed production for repetitive patterns — faster than laser on high-density hole grids
- Multiple punch profiles in a single setup — combined operations without remounting
- Consistent hole-to-hole accuracy across the full sheet
- Cost-effective for production volume on standard hole patterns
- Deburr-free or deburring-capable, depending on specification

Applications
Electrical
Ventilation panels and mounting plates for electrical cabinets and enclosures
Industrial Equipment
Equipment guard panels, machinery housings, access covers with hole patterns
Furniture & Racking
Perforated shelves, louvre panels, cabinet vent strips
Data Centre
Rack ventilation blanking panels, cable entry panels
General Fabrication
Any sheet requiring repetitive holes, slots, louvres, or formed features at volume
Customization
Material, sheet thickness, hole size and type, pattern layout (from DXF), louvre configuration, quantity, and any deburring or surface treatment requirement can be specified. Stored punch programs enable repeat orders without re-setup.
Our Process
Requirement
Part specs, quantity, and material grade confirmed with the client.
DXF / Pattern Review
Hole layouts and formed features checked against the punch program.
Tooling Selection
Punch and die tools matched to each hole shape and sheet thickness.
CNC Punching
Sheets punched on the CNC turret to the reviewed program.
Deburring
Punched edges and holes cleared of burrs before final checks.
Dispatch / Next Process
Parts released to bending, welding, or direct dispatch.
Quality & Engineering
Punched components are dimensionally checked for hole position and size before proceeding. Punch program accuracy is verified at batch start. Deburring is performed as required. SS material is protected from scratch during punching.
