Tolerance of tolerance
There is not a given set of tolerances that fits all processes and materials. In every case, the final tolerances on your part will depend on a number of factors, including but not limited to:
●Part size
●Design geometry
●The number, type, and size of features
●Material(s)
●Surface finish
●Manufacturing process
Once your order is confirmed, we will review your design and provide a design for manufacturing review, pointing out any areas where we may not be able to achieve your desired tolerances. It’s helpful if you can specify which areas in your design have critical tolerances that must be met and which can be slightly modified if needed to reduce the time and costs involved.
All manufacturing and technical specifications need to be clearly specified in the 2D drawings in order to be followed.
