关于细密零部件来说，，，大连细密零部件加工是十分严酷的，，，加工工序有进刀，，，出刀等。。。。关于尺寸有详细要求，，，精度也有要求，，，好比1mm正负几多微米等，，，若是尺寸错的太多就会成为废品，，，这时就相当于得重新加工，，，费时艰辛，，，有时甚至会使得整个加工质料报废，，，这就造成了本钱的增添，，，同时，，，零件是肯定不可用了。。。。

For precision parts, Dalian Precision Parts Processing is very strict, with machining processes such as cutting in and cutting out. There are specific requirements for size and accuracy, such as 1mm plus or minus micrometers. If there are too many errors in size, it will become a waste product, which is equivalent to reprocessing, time-consuming and laborious. Sometimes it may even cause the entire processing material to be scrapped, resulting in increased costs. At the same time, the parts are definitely unusable.
