CNC turning (also known as CNC lathes) is a subtractive manufacturing process in which a stationary cutting tool removes material by making contact with the spinning workpiece to create the desired shape.
During processing, a blank bar of stock material is held in the chuck of the spindle and rotated with the spindle. Extreme precision and repeatability can be achieved under the control of computer instructions for the movement of the machinery.
When CNC turning rotates the workpiece in a chuck, it’s generally to create round or tubular shapes and achieve far more accurate rounded surfaces than CNC milling or other machining processes.
Turning Typical Tolerances
The table below summarizes the recommended values and essential design considerations to help to improve cosmetic appearance, enhance part manufacturability, and lower overall production time.
|
Type |
Tolerance |
| Linear dimension | +/- 0.025 mm +/- 0.001 inch |
| Hole diameters (not reamed) | +/- 0.025 mm +/- 0.001 inch |
| Shaft diameters | +/- 0.025 mm +/- 0.001 inch |
| Part size limit | 950 * 550 * 480 mm 37.0 * 21.5 * 18.5 inch |
Available Surface Treatment Options
Surface finishes are applied after milling and can change the appearance, surface roughness, hardness and chemical resistance of the produced parts. Below are the mainstream surface finish types.
| As machined | Polishing | Anodized | Bead Blasting |
| Brushing | Screen Printing | Heat Treating | Black Oxide |
| Powder Coating | Painting | Engraving | Plating |
| Brushing | Plating | Passivating |

Frequently Asked Questions
Turning involves a process where CNC lathes cut the bar of stock material into circular shapes. The workpiece is placed in the lathe and rotated while the tool removes the material until only the desired shape is left.
Turning is an ideal choice for producing cylindrical parts, mainly using round bar stock, but square and hexagonal ones can also be used.
CNC turning is a method for making symmetrical cylindrical parts. Typical examples are shafts, gears, knobs, tubes, etc. CNC turned parts are usually applied to various applications and industries like aerospace, medical, automotive, and other industries.
CNC lathes are usually two-axis machines with only one spindle. Their production capacity is not high, and there is usually no protective casing around the machine. A CNC turning center is a more advanced version of a CNC lathe, with up to 5 axes and more general cutting capacity. They also provide the ability to produce larger volumes, often integrating milling, drilling, and other functions.
We can serve more than 10000 pcs of different prototypes monthly, no matter the part with simple or complex design. We own 60 CNC machines and have more than 20 experienced technical experts.
