CNC Turning

Turning produces the rotational geometry milling cannot: diameters, bores, grooves, threads and concentric faces. The factory's equipment list includes CNC lathes alongside its machining centres and milling machines, so a part that needs both turned and milled features is planned as one job — turned first for its datums, milled second for its flats and patterns, or the reverse, as the geometry dictates.

Stainless lock parts and spare parts are the range's natural turned families: rotational, fit-critical, reordered over years. Aluminum turned parts serve the same assemblies as our milled and cast range, keeping material and finish consistent across a product.

A turned part usually exists to fit something: a shaft in a housing, a bushing in a bore, a lock cylinder in its mechanism. Fits are relationships, and this factory often makes both sides of the relationship — the cast or machined housing as well as the turned insert. When both sides come from one inspection system, fit problems are found on the CMM, not on the customer's assembly line.

If you are replacing a worn turned component, the spare-part route applies: send the sample or drawing, and the review will define what must be matched — diameters, threads, material grade (SS303/SS304 where stainless) — before quoting.

Mark concentricity-critical features, thread specifications and the faces that locate the part in its assembly. State the grade — aluminum or stainless SS303/SS304 per this range — and whether a finish applies. Quantities for trial and production complete the enquiry; with no fixed MOQ, a short proving run is a normal way to start a turned-part relationship.

Machining programmes stay healthy on two habits. First, keep the drawing and the inspection plan married: the dimensions flagged critical at review are the dimensions the CMM programme measures, so a drawing revision should always travel with a note about what changed functionally — production will re-plan operations and inspection from it. Second, protect the starting-point decision. As quantities grow, a part begun from bar may deserve re-examination as an extrusion- or casting-based part with finish machining only; the review re-opens that question at volume milestones rather than letting a prototype route harden into a production cost.

Buyers transferring an existing part should say so at enquiry. A part proven elsewhere, a part needing re-specification from a sample, and a brand-new design are three different projects with three different first steps, and the review will name which one you have before quoting anything.
