Standard Tolerances


In the absence of tolerances specified on a customer drawing, MCE uses standard tolerances. These are listed below, along with what is the best tolerances we can hold, however, at a higher cost.

Standard MCE tolerances and best possible are as follows:

As tolerances are tightened and greater demands are imposed on achieving a "perfect" part, costs begin to escalate rapidly. Good engineering practices require taking costs into consideration to produce a viable product for a particular application. Please give careful consideration as to what you really need so that we can provide a competitive product for your application.
