CNC Tolerance Guide
| Machining Type | Standard Tolerance | High Precision | Surface Roughness |
|---|---|---|---|
| 3-Axis Milling | ±0.1 mm | ±0.02 mm | Ra 1.6 μm |
| 5-Axis Milling | ±0.05 mm | ±0.01 mm | Ra 0.8 μm |
| CNC Turning | ±0.05 mm | ±0.005 mm | Ra 0.4 μm |
Design Guidelines
- Minimum wall thickness: 0.8mm
- Minimum hole diameter: 0.5mm
- Avoid sharp corners
- Respect depth limitations
Tooling & Cutting Speeds
- Correct tool selection
- Optimal cutting speeds
- Cooling and lubrication
- Workpiece clamping
Precision starts at the design — respect the capabilities and tolerances of each CNC process.
