At YUANYI, CNC turning is about much more than simply machining parts according to drawings. Every project begins with a comprehensive review of material selection, tolerance requirements, machining strategies, and production feasibility, all aimed at effectively mitigating manufacturing risks before production begins.
Our team combines over a decade of CNC programming and machining experience with a pragmatic, engineering-driven approach to production. Whether you need prototypes, small-batch manufacturing, or ongoing mass production, we are committed to ensuring consistent quality, efficient machining processes, and reliable delivery.
From precision shafts and bushings to threaded assemblies and various custom CNC-turned parts, we work closely with our customers to provide practical machining solutions that balance precision, cost, and manufacturability.
Every CNC turning project is reviewed by our engineering team before machining begins, helping reduce production risks and improve manufacturability.
Experienced programmers and machinists support precision CNC turning projects involving shafts, bushings, threaded parts, and custom components.
From prototype CNC turning to small-batch and production orders, we support flexible quantities with no minimum order quantity requirement.
Critical dimensions can be verified through in-process inspection, final inspection, and quality reports to ensure stable and reliable results.
Our CNC turning capabilities include conventional turning, Swiss-type machining, and mill-turn compound machining. Each process offers unique advantages depending on part geometry, tolerance requirements, and production goals, allowing us to provide the most suitable machining solution for every project.
Our turning service is suitable for a wide range of cylindrical parts, including shafts, bushings, pins, threaded components, and custom machined parts. With experienced machinists and stable production processes, we support everything from prototype development to volume production while maintaining consistent quality and machining accuracy.

Swiss-type machining is ideal for small-diameter components that require tight tolerances, excellent surface finishes, and high repeatability. This process is widely used for medical devices, electronics, sensor components, and other precision parts where dimensional consistency is critical.
Explore Swiss Machining
Mill-turn compound machining combines turning and milling operations within a single setup, reducing secondary operations and improving positional accuracy. It is an efficient solution for complex parts that require holes, slots, flats, threads, and multiple machined features.
