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.
