CNC turning process is a precision machining technique that uses a computer-controlled lathe to manufacture cylindrical or round-shaped parts. In this process, a rotating workpiece is fed into a stationary cutting tool to remove material and form the desired shape, including various types of threads. CNC turning demonstrates exceptional efficiency when machining round parts such as shafts, worms, and spheres. The movement of the workpiece and cutting tool is precisely controlled by CNC (Computer Numerical Control) software, ensuring high precision and repeatability in part production. This makes CNC turning particularly suitable for mass production.

Surface Finishes for CNC Turning
As Milled – Cutter marks from the CNC turning process will be present, with surface roughness achievable up to Ra 0.8.
Anodized – A thin, hard, non-conductive coating is formed on the surface of aluminum parts. The parts can be anodized in different colors.
Heavy Bead Blast – This treatment removes heavier cutter marks and scratches left by sandpaper, giving the surface a light textured appearance.
Smooth Finish – Typically achieved with 600-grit sandpaper, followed by polishing to achieve a smoother surface.
Powder Coat – A strong, wear-resistant, and corrosion-resistant polymer protective coating is applied to the surface of the part. A variety of colors can be used to achieve the desired aesthetic effect.
Tolerances for CNC Turning

Overview of CNC Turning
What’s CNC Turning?
CNC milling and CNC turning are two fundamental types of CNC machining processes, each with distinct methods and applications. CNC milling utilizes rotary cutting tools that approach the stationary workpiece from multiple angles to shape complex geometries. In contrast, CNC turning employs a lathe to rotate the workpiece—typically a rod stock made of metal—while stationary or live tooling machines cylindrical features.
Our CNC turning process is ideal for producing functional prototypes and end-use parts with high precision. It enables the creation of axial and radial holes, flats, grooves, and slots by rotating the material against live tooling. Unlike milling, where the tool moves and the part remains fixed, turning relies on the rotation of the part itself to achieve the desired form.
How Does CNC Turning Work?
CNC lathes operate on a subtractive manufacturing principle to shape raw materials into precise components. Once the “G-code” is generated, the raw bar stock is loaded into the chuck of the lathe’s spindle. As the spindle begins to rotate, the chuck securely holds the workpiece in place. When the spindle reaches its designated speed, a stationary cutting tool is precisely positioned to engage the rotating material, gradually removing excess material until the final geometry is achieved.
CNC turning is ideal for producing rotationally symmetrical parts, enabling rapid material removal while achieving superior surface finishes—often eliminating the need for additional post-processing.
Advantages of CNC Turning
Cylindrical Parts
CNC turning machines are the preferred solution for producing round or cylindrical components. This process ensures fast, precise, and consistent machining, making it ideal for high-efficiency production of symmetrical geometries.
Range of Processes
While CNC turning is primarily used for round or cylindrical parts, it is also highly versatile—capable of performing a wide range of operations such as drilling, boring, threading, knurling, and more.
