What is CNC turning?

CNC turned parts are produced using a CNC lathe, where the workpiece rotates while a stationary cutting tool shapes the material. This process is ideal for creating cylindrical or symmetrical components such as shafts, bushings, and fasteners with precise dimensions. CNC turning allows for high repeatability and accuracy, often holding tolerances as tight as ±0.001". The method is efficient for producing parts in a range of materials, including metals like steel, aluminum, and brass, as well as plastics. CNC turning is widely used in industries such as automotive, aerospace, and medical manufacturing, where precise, high-quality components are essential.

General CNC machining FAQs

What is CNC turning?

CNC turning is a precision machining process where a rotating workpiece is shaped by a stationary cutting tool to create cylindrical or symmetrical parts. Controlled by computer numerical control (CNC) systems, the machine uses programmed movements to achieve high precision and consistent quality. The workpiece is clamped into a chuck and rotated at high speeds, while cutting tools move along the X and Z axes to remove material, making it ideal for producing parts like shafts, bushings, and threaded components. CNC turning can create straight, tapered, or contoured surfaces and is used extensively in industries such as aerospace, automotive, and medical manufacturing. It works with a wide variety of materials, including metals and plastics, offering accuracy, repeatability, and efficiency for both small and large production runs.

Is CNC turning the same as traditional lathe machining?

CNC turning and traditional lathe machining are similar processes, but they are not exactly the same. Both involve rotating a workpiece while a cutting tool shapes it, but CNC turning is an automated process controlled by computer numerical control (CNC) systems, allowing for precise, repeatable, and complex part production. In contrast, a traditional lathe is typically manually operated, requiring the machinist to control the cutting tool’s movements. CNC turning offers greater efficiency, accuracy, and the ability to produce intricate geometries compared to manual lathe operations, making it more suitable for high-volume and precision manufacturing.

What are the benefits of CNC turning over other machining processes?

CNC turning is highly efficient for producing symmetrical, cylindrical parts with tight tolerances, offering speed, precision, and repeatability.

What is the typical lead time for CNC turned parts?

Lead times vary based on the complexity and volume of the order but are typically between 3 and 6 weeks for production parts.

What kind of surface finishes can be applied to CNC turned parts?

We offer various surface finishes, including anodizing, plating, polishing, and powder coating, depending on your specifications.

Technical CNC Turning FAQs

What are the typical tolerances for CNC turned parts?

Our CNC turning can achieve tolerances as tight as ±0.001" (±0.025 mm), depending on the material and design complexity.

What materials can be CNC turned?

We can CNC turn a wide variety of materials, including metals like aluminum, steel, brass, and titanium, as well as plastics such as nylon, PEEK, and acrylic.

Can you produce custom threads on CNC turned parts?

Yes, we can produce standard and custom threads on CNC turned parts. Custom threads will require a more extensive quote process.
