Computer Numerical Control (CNC) machining is a subtractive manufacturing process — the controlled removal of material from a workpiece by a rotating cutting tool along a programmed toolpath. The industrial standard for metallic components requiring high tolerance classes.
CNC operations are driven by G-code — a machine language generated by CAM software from a 3D CAD model (STEP, IGES, Parasolid). Multi-axis centres (3-, 4- and 5-axis) enable machining of complex surfaces in a single setup, minimising the cumulative error from re-fixturing.
Cutting parameters — spindle speed (RPM), feed rate, depth of cut (DOC) and tool wear — are optimised per material. Post-processing options include anodising, ceramic coating, grinding and passivation for corrosion protection.
General-purpose Al-Mg-Si alloy in the T6 temper (solution heat treated and artificially aged). Tensile strength ~310 MPa, yield strength ~275 MPa. Excellent weldability, very good corrosion resistance and machinability. Standard choice for structural components, chassis and enclosures.
Premium aerospace-grade Al-Zn alloy. Tensile strength ~570 MPa — close to that of structural steel at ~3× lower density. Outstanding strength-to-weight ratio. Used for highly loaded components, weapon systems, sport and aerospace equipment.
Copper-zinc alloy with excellent machinability (especially the leaded variant), an attractive golden-yellow colour and good corrosion resistance. Electrically conductive. Applications: decorative parts, fittings, electrical contacts, precision mechanics.
Copper-tin alloy. High wear resistance, low friction, good bearing properties. Used for bushings, bearings, worm gears and components subject to continuous friction.
Capability to machine C45, AISI 304, AISI 316L and tool steels. Suited to components with high mechanical or corrosion requirements.
The hybrid approach combines the additive strengths of 3D printing (complex internal geometries, fast iteration) with the subtractive precision of CNC machining (critical mating surfaces, threaded holes, fitting diameters). The result is an optimised component with minimised material waste and maximised functional value.
