CNC Machining Tolerances

Standard and achievable tolerances for our CNC machining services.

Process Standard Tolerance Precision Tolerance
CNC Milling±0.05 mm±0.01 mm
CNC Turning±0.05 mm±0.01 mm
5-Axis Machining±0.03 mm±0.005 mm
Precision Grinding±0.01 mm±0.005 mm
Surface Finish (Ra)Ra 1.6 μmRa 0.4 μm

Notes

Achievable tolerances depend on part geometry, material, and feature size. Tighter tolerances may increase cost and lead time.

All parts are inspected using Zeiss and Hexagon CMM equipment with measurement accuracy down to 0.0009mm.

For specific tolerance requirements, please contact our engineering team for a DFM review.
