一、拉削中的问题及影响 光洁度的主要因素 拉削是金属切削加工中高生产率的方法之一,同时又能获得较高的加工精度和表面光洁度。因此,拉削在金属切削加工中占有相当重要的地位,国内外拉削工艺都得到了广泛采用。但由于拉削加工是一项较新的工艺,到目前为止,大家对它都还不太熟 First, the problems in broaching and the main factor affecting finish Broaching is one of the methods of high productivity in metal cutting, and at the same time it can obtain higher machining precision and surface finish. Therefore, broaching in metal cutting occupies a very important position, broaching process at home and abroad have been widely adopted. However, as the broaching process is a relatively new technology, so far, everyone is not too familiar with it
