大连细密零部件加工圆柱为例：好比圆柱直径是几多，，，，，有严酷要求，，，，，正负误差在划定要求规模之内才是及格零件，，，，，不然都是缺乏格零件；；；如一个内嵌式圆柱体，，，，，若是直径太大，，，，，凌驾误差允许规模内，，，，，就会造成，，，，，插不进去的情形，，，，，若是现实直径太小，，，，，凌驾误差允许负值下限了，，，，，就会造成插进去太松，，，，，不牢靠的问题爆发。。

这些都是缺乏格产品，，，，，或者圆柱长度太长或太短，，，，，凌驾误差允许规模了，，，，，都是缺乏格的产品，，，，，是都要作废的，，，，，或者重新加工，，，，，这样必定会造成本钱的增添。。

其次就是优质的非标细密零件加工装备和检测装备，，，，，优质的加工装备使得加工细密零件的时间越发简朴，，，，，精度更高，，，，，效果更好。。

Taking the example of precision machining cylinders in Dalian: for example, there are strict requirements for the diameter of the cylinder, and only qualified parts are those with positive and negative errors within the specified range. Otherwise, they are all unqualified parts; If the diameter of an embedded cylinder is too large and exceeds the allowable error range, it will cause a situation where it cannot be inserted. If the actual diameter is too large

If the error exceeds the lower limit of the allowable negative value, it will cause the problem of inserting too loosely and not firmly.

These are all unqualified products, or if the cylinder length is too long or too short, exceeding the allowable error range, they are all unqualified products and must be invalidated or re added

This will inevitably lead to an increase in costs.

Next is high-quality non-standard precision parts processing equipment and testing equipment. High quality processing equipment makes it easier, more accurate, and effective to process precision parts

Better.
