The achievable tolerance depends on the material, part size, geometry, machining process and specific feature.
It would be misleading to quote one universal tolerance for every CNC machined component. A small aluminum component with straightforward geometry may achieve a different tolerance from a large 316L stainless steel component with deep cavities or thin walls.
For precision components, we review critical dimensions individually and determine the appropriate machining process and inspection method.
If your drawing contains tight tolerances, please identify the critical features clearly. We can evaluate manufacturability during the quotation stage and advise whether the requested tolerance is practical for the selected material and geometry.
