不锈钢进口泵零件精密加工，非标定做，例如圆柱体直徑几多钱，有严格治理，正负极误差在规章要求界限以内才算是合格零件，要不然满是吩扃格零件;如一个嵌入式圆柱，倘若直徑很大，逾越误差应许界限内，就会产生，插不进去的情况，倘若内容直徑很幼，逾越误差应许负数低限了，就会产生放进去很松，不不变的难题造成。

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.
