CNC turning process for round metal components

Overview: What is CNC Turning?

CNC turning is a manufacturing process used to create cylindrical parts by rotating the workpiece against a stationary cutting tool. The tool removes material to achieve the desired shape and dimensions.

Computer numerical control (CNC) system that automatically controls the tool’s movement path, rotational speed and feed rate according to pre-programmed instructions (G-code), thereby producing the desired shapes—such as outer cylinders, inner bores, end faces, tapers and threads.

On high-precision lathes, ultra-smooth surfaces with a roughness of Ra 0.04–0.01 μm can be achieved by high-speed cutting of non-ferrous metals using finely honed diamond cutting tools, with machining accuracy reaching grade IT7–IT5.

CNC turning is the cornerstone of modern manufacturing. This process is indispensable for producing everything from simple screws to complex aero-engine shafts.

FAQ

No MOQ. We really understand the RD phase specialize in supporting projects from a single prototype through to low-volume production. We understand R&D needs and apply the same rigorous process and quality control, whether for one part or one hundred.

Please provide your 3D model (STEP/IGES preferred) and 2D drawings (with critical dimensions, tolerances, material, and finish specified). We will provide a transparent, detailed quotation based on machining time, material, complexity, and post-processing, with no hidden costs.

 For parts of standard complexity, our typical CNC machining lead time is 7-15 working days (from confirmed drawings/payment). We offer expedited service with delivery in 1-3 working days, subject to part evaluation and an additional rush fee.

Our standard machining tolerance is ±0.025 mm (±0.001″). For critical features, we can achieve ±0.005 mm (±0.0002″) or better, depending on part geometry and material. We will perform a DFM analysis and confirm all critical tolerances with you upon receiving your drawings.

Yes, it’s part of our standard process. We perform First Article Inspection (FAI) and can provide inspection reports (e.g., dimensional check sheets, CMM data for critical features) upon request. Our full suite of inspection tools (calipers, micrometers, CMM, etc.) ensures every batch meets your specifications.

We stock various aerospace and commercial-grade metals and plastics, such as Aluminum (6061, 7075), Stainless Steel (304, 316), Carbon Steel, Brass, PEEK, Delrin, etc. For critical projects, we can provide mill certificates for the raw materials upon request.

Your intellectual property is our top priority. We are glad to sign a legally-binding Non-Disclosure Agreement (NDA) before any project begins. All digital files are stored on encrypted servers with access strictly limited to the project team.

We are committed to 100% customer satisfaction. If a non-conformance is confirmed to be our manufacturing fault, we will remake or repair the parts at no cost and cover the resulting shipping fees. We ask that you inspect the parts promptly upon receipt and provide a detailed description with photos/video.

We provide various post-processing services, including: Bead blasting, Anodizing (Type II & III, various colors), Electroless Nickel Plating, Passivation, Electroplating, Powder Coating, and Silk Screening. We can advise based on your functional or aesthetic requirements.

For new clients, our standard terms are “50% deposit to start production, 50% balance before shipment.” We accept international payment methods like Wire Transfer and PayPal. Terms can be discussed for established, long-term partnerships.
