铰孔是孔精加工中最常用的一种加工方法,也是机械加工过程中的最后一道工序,决定着零件合格与否。铰孔加工完的工件孔常产生一些缺陷或废品,其原因很不好查找,难以快速采取措施加以解决。根据笔者30余年的现场实践经验记录,并参阅一些国内外有关资料.现将铰孔时孔表面常产生的一些缺陷或废品形式产生的原因及解决方法归纳如表1所列。 Reaming hole is the most commonly used in precision machining of a processing method, but also the last process of machining process, determines the parts or not. Reaming the workpiece hole often produce some defects or waste, the reason is not good to find, it is difficult to take prompt measures to be resolved. According to the author more than 30 years of field practical experience records, and refer to some domestic and foreign relevant information.Now reaming hole surface often produce some defects or waste forms of the causes and solutions summarized in Table 1.
