What is CNC Turning?
CNC turning is a substractive manufacturing process that create turned parts by rotating the rod material against a cutting tool, it is commonly used for functional prototypes and end-use parts with axial and radial holes, flats, grooves, and slots. If your parts design has symmetrical cylindrical or spherical features, CNC turning is recommended for you.

Surface Finishes for CNC Turning
CNC turned parts are left as-milled, and surface finsih can change the appearance, surface roughness, hardness and chemical resistance of the produced parts. Determined by the material using, a part can have one to serval available surface finishing options. Learn more at our surface finish page.
Anodizing changes the surface state and performance of the material, thus improving corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface.

CNC Turning Design Recommendations
Result from the processing features, CNC turning has slightly diffrent design guidelines with CNC milling process. Following these recommendations can greatly benefit the production efficiency and reduce cost. Learn more about CNC design guides.
Recommended: 0.8 mm (metals), 1.5 mm (plastics)
The less wall thickness, the less material stiffness. It will lead to the vibrations during machining and lower accuracy. We recommend you use even larger minimum wall thickness for plastics.
Recommended Diameter: standard drill bit sizes
Recommended Depth: 4 - 40 times nominal diameter
The tools used for drilling holes are either drill bit or end mill tool. For high accuracy holes smaller than ⌀20 mm, using a standard diameter is recommended.
Recommended size: M6 or larger
Recommended length: 3 times nominal diameter
Threads are divided into internal and external ones. Internal threads are cut with taps, while external threads with dies. Taps and dies can be used to cut threads down to M2. CNC threading tools are common and they are preferred, as they limit the risk of tap breakage.
