不锈钢入口泵零件细密加工，，，，，，非标定做，，，，，，例如圆柱体直徑几多钱，，，，，，有严酷治理，，，，，，正负极误差在规章要求界线以内才算是及格零件，，，，，，要不然全是不同格零件;如一个嵌入式圆柱，，，，，，倘若直徑很大，，，，，，跨越误差应许界线内，，，，，，就会爆发，，，，，，插不进去的情形，，，，，，倘若实质直徑很小，，，，，，跨越误差应许负数低限了，，，，，，就会爆发放进去很松，，，，，，不稳固的难题造成。。。。。。

Precision machining of stainless steel imported pump parts, non-standard customization, such as the cost of cylinder diameter, with strict management. Positive and negative electrode deviations within the regulatory requirements are considered qualified parts, otherwise they are all non-conforming parts; If an embedded cylinder has a large diameter and crosses the tolerance line, it may not fit in. If the actual diameter is small and crosses the negative limit of the tolerance line, it may become loose and unstable to fit in.
