近年工业制品的趋向是轻薄短小化,当然要求组成这些制品的零件结构小形精密。于是占机械加工量1/4或1/3的加工也必然出现同一倾向,也就是要求要小尺寸精度要高。这就是专门研究微细小径深孔加工的原因。小径深孔加工是机械加工中最难的加工之一,它们无法修整,存在很多问题,这些问题将在下面叙述,克服这些问题是成功地解决微细小径深孔加工的一把钥匙。 In recent years, the tendency of industrial products is slim and light, of course, require the composition of these parts is small and sophisticated structure. So, accounting for machining 1/4 or 1/3 of the processing is bound to appear the same tendency, which is required to be higher precision of small size. This is the reason that specializes in deep hole processing of small diameter tracks. Small hole deep hole machining is one of the most difficult machining in machining. They can not be trimmed. There are many problems that will be described below. Overcoming these problems is a key to the successful solution to the deep hole machining of small diameter tracks.
