CNC Machining

CNC machining is a precision subtractive process in which computer-controlled cutting tools remove material from a solid workpiece to produce finished parts. Our service covers three core capabilities: CNC milling, CNC turning, and cylindrical grinding. Common work includes shafts, gear blanks, pump and gearbox components, and production tooling.

CNC Milling

CNC milling removes material from a stationary workpiece using rotating cutting tools, producing flat surfaces, contours, slots, pockets, and drilled features. Our 3-axis vertical machining centre handles prismatic parts including plates, housings, brackets, and feature-rich engineering components.

CNC Turning

CNC turning rotates the workpiece against a fixed cutting tool to produce cylindrical and rotationally symmetric features. The process handles external diameters, internal bores, faces, tapers, threads, and grooves on parts up to 300 mm diameter and 2000 mm long. Typical work includes shafts, bushes, hubs, and threaded components.

Cylindrical Grinding

Cylindrical grinding uses an abrasive wheel to finish cylindrical surfaces to tighter tolerances and finer surface qualities than turning alone can achieve. The process is used as a finishing step on shafts, spindles, bearing journals, and other rotating components where running fit and surface quality are critical.

Sheet Metal Fabrication

Sheet metal fabrication converts flat sheet and tube into finished parts through cutting, punching, forming, and bending operations. Our service is grouped into two clusters: cutting (flat sheet and tube) and bending (press-brake forming). Common output includes enclosures, brackets, frames, structural components, and tube assemblies.

Laser Cutting

Laser cutting uses a focused fibre laser beam to vaporise material along a programmed path. The process delivers clean cuts with a minimal heat-affected zone, precise contours, and tight repeatability across long production runs.

CNC Punching

CNC turret punching uses a rotating tool head to punch, cut, and form sheet metal in a single setup. Beyond cutting, the process produces embossed features, countersinks, louvers, extruded flanges, and tapped holes, reducing the need for separate secondary operations.

Metal 3D Printing

Metal 3D printing builds finished parts layer by layer from CAD data, fusing fine metal powder with a focused laser. Our system uses Selective Laser Melting (SLM) powder-bed fusion technology, suited to complex internal geometries, topology-optimised structural parts, dental and medical components, functional prototypes, and tooling inserts. Small-batch production is cost-effective without conventional tooling, and printed parts can be laser-welded to machined components for hybrid assemblies.

Extrusions

Aluminium extrusion forces heated billet through a shaped steel die to produce continuous profiles in standard or custom cross-sections. The process suits long structural members, framing systems, enclosures, channels, heat-dissipating profiles, and parts that integrate directly into larger assemblies. Profiles are supplied cut to length and can be machined, drilled, threaded, or surface-finished as secondary operations.

Heat Treatment

Heat treatment uses controlled heating and cooling cycles to modify a material's hardness, toughness, machinability, or internal stress state. Our services fall into two groups: bulk treatments that act through the full cross-section of the part, and surface treatments that act only on the outer case.

Bulk Heat Treatment

Modifies material properties through the full cross-section. Used to set core hardness, refine grain structure, or relieve internal stresses.
