CNC Milling vs CNC Mill-Turning vs 5-Axis CNC Machining
CNC Turning Service Overview
CNC turning is a precision machining process used to produce cylindrical and rotational parts with high accuracy and repeatability. It is widely applied across industries that require tight tolerances and consistent surface finishes.
Key Features of CNC Turning
During CNC turning, the workpiece rotates while a cutting tool removes material to achieve precise diameters, profiles, and surface finishes. This process is highly efficient for round and symmetrical components.
- High dimensional accuracy and excellent repeatability
- Efficient machining of cylindrical and round parts
- Stable control of concentricity and surface finish
- Suitable for prototypes and production runs
- Supports a wide range of metals and engineering plastics

Quality Control in CNC Milling
Quality control is an integral part of our CNC milling process. From raw material inspection to final dimensional verification, each step is managed to ensure accuracy, repeatability, and reliable performance for precision machined parts.
Incoming Material Inspection
Raw materials are inspected upon arrival to verify specifications, material grade, and surface condition before entering the CNC milling process.
In-Process Dimensional Control
Key dimensions are monitored during machining to minimize variation and ensure stable tolerance control throughout production.
Final Inspection Before Shipment
Finished parts undergo final dimensional and visual inspection to confirm conformity with drawings and customer requirements.

CNC Milling Parts Tolerances & Standards (ISO 2768)
Our CNC milling parts are manufactured according to ISO 2768 general tolerances unless otherwise specified on the engineering drawing. This standard is widely applied to custom CNC milled components and defines permissible dimensional variations when individual tolerances are not indicated.
| Feature | Standard Tolerance |
|---|---|
| Linear dimensions | ±0.1 mm |
| Hole diameter | ±0.05 mm |
| Shaft diameter | ±0.05 mm |
| Flatness | ISO 2768-m |
| Parallelism | ISO 2768-m |
| Perpendicularity | ISO 2768-m |
| Angular dimensions | ISO 2768-m |
Tighter tolerances can be achieved for critical functional features depending on part geometry, material, and machining method. If no tolerance is specified on the drawing, ISO 2768-m will be applied as the default standard. Please clearly indicate any special tolerance requirements in your technical documentation.
