Automotive FAQs
-
What tolerance levels are typically achievable for automotive CNC parts? 1
-
For most automotive components, standard tolerances of ±0.05 mm are commonly achievable, with tighter tolerances applied only where function requires it. Critical interfaces, alignment features, or rotating components can be controlled to tighter limits based on design intent.
Actual tolerances depend on part geometry, material, and functional requirements rather than a fixed blanket standard.
f you require a more detailed explanation, please contact us.
