The starter assembly line is one of our products. Let me share with you two methods to ensure the dimensional accuracy of assembly.
(1) Complete interchange method:
Readjust the tolerance or nominal size of several rings in the ring, so that the obtained closed ring can meet the accuracy requirements. This is the most ideal way, but doing so has to improve the machining accuracy of one or several parts, which is difficult.
(2) Group interchange method;
The grouping interchange method can only be used when the number of size links is small and the limit range of the closed ring is very high. If the complete interchange method is used, it is bound to increase the accuracy of the parts excessively, increase the processing difficulty of the parts, and it is also extremely uneconomical.

In the assembly work such as holes, the grouping interchange method is often used.
