CNC Milling Tolerances
Taidexing specializes in high-precision CNC milling services. We maintain strict dimensional control to meet demanding specifications for aerospace, medical equipment, automotive, electronics and other precision manufacturing sectors. Below lists our standard precision benchmarks and maximum achievable tolerances for typical machining features.
| Machining Feature | Standard Tolerance | Maximum Achievable Precision |
| Linear Dimensions | ±0.125 mm (±0.005") | ±0.01 mm (±0.0004") |
| Hole Diameter | ±0.1 mm | ±0.005 mm (via boring or reaming) |
| Flatness | 0.1 mm per 100 mm | 0.02 mm per 100 mm |
| Surface Roughness | Ra 3.2 μm | Minimum Ra 0.8 μm (after fine finishing) |
