Turning rotates the workpiece against a stationary cutting tool, suited to cylindrical or round parts like shafts, bushings and pins. Milling moves a rotating cutting tool across a stationary or indexed workpiece, suited to flat, angled or complex 3D geometries like brackets, housings and plates. Many precision components need both processes combined, which multi-axis machining centres and lathes handle in one setup.

As-machined (standard finish straight off the tool), anodizing (aluminium, for corrosion resistance and colour coding), plating (various metals, for corrosion protection or conductivity) and powder coating are the common options. Specify your finish requirement alongside the dimensional drawing, since finish affects both process routing and lead time.

Raw material is tracked by heat/batch number from receipt through to the finished part, with the Mill Test Certificate for that specific heat retained and referenced on the component's documentation. This is standard practice for defence, aerospace-adjacent and critical industrial applications. Confirm this level of traceability is included if your project requires it, since it adds administrative overhead not present in simpler commercial work.

Steel (EN 8, EN 19, EN 24, EN 36), stainless (304, 316, 17-4 PH), aluminium (6061, 6063, 7075), brass, bronze, and specialty alloys (Inconel, titanium, monel) on request. Material certs travel with every batch. For defence we hold special-grade material under controlled storage.
