不銹鋼進口泵零件精密加工，非標定做，例如圓柱體直徑多少錢，有嚴格管理，正負極偏差在規章要求界線以內才算是合格零件，要不然全是分歧格零件;如一個嵌入式圓柱，倘若直徑很大，跨越偏差應許界線內，就會產生，插不進去的情況，倘若實質直徑很小，跨越偏差應許負數低限了，就會產生放進去很松，不穩定的難題造成。
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.
