CNC Milling Tolerance
AT CNCNOW, we use the latest 3 and 5-axis CNC machines that offer high precision and accuracy, and ensure tight tolerances for all of our machined parts. Our standard milling tolerances are:
- 300mm (12”) part size – Tolerances of ± 0.125mm (0.05”), angularity of ± 0.5°
- 600mm (24”) part size – Tolerances of ± 0.250 mm (0.10”), angularity of ± 1.0°
- 900mm (36”) part size – Tolerances of ± 0.400 mm (0.15625”), angularity of ± 1.0°

It is possible for us to produce parts with tolerances as low as ± 0.020mm (.0008”). Any tolerance tighter than this will require a consultation with our technical team.
