What is CNC Turning?‌How Does CNC Turning Work?

CNC Turning is an automated manufacturing process that transforms a solid block or rod of material into a part using end mills. The end mills are controlled by software (G-code) which references a 3D CAD model to reduce the stock material into a desired geometry. Parts can be manufactured relatively quickly due to the level of automation.
  • Design & Programming‌: A CAD model defines the part geometry, which is converted into G-code via CAM software.
  • Tool Selection‌: Suitable cutting tools (end mills, face mills, drills) are chosen based on material and design requirements.
  • Workpiece Setup‌: The raw material (metal, plastic, or composite) is securely clamped to the machine bed.
  • Automated Machining‌: The CNC machine moves the rotating tool across multiple axes to cut the workpiece, layer by layer, until the final shape is achieved.
  • Post-Processing‌: Secondary operations like sanding, anodizing, or heat treatment may enhance surface finish or durability.
