对于一些径深比较小且孔加工精度要求较高的深孔类零件,可以在普通钻床上采用拉铰工艺进行加工,要想确保拉铰效率和加工质量,关键在于工艺措施得当并选择合适的刀具。介绍一种采用普通铰刀改制拉铰刀进行深孔拉铰的工艺方法,由于不需要订购专用刀具,生产成本较低,非常适用于中小企业加工此类零件使用。
For some deep-hole parts with smaller diameter and higher hole machining accuracy, the drawing process can be processed on the ordinary drilling machine. To ensure the pull-drawing efficiency and processing quality, the key lies in that the process measures properly and select the appropriate Tool. Introducing a reaming reaming reaming knife used for deep hole pull hinge process method, because no need to order special tools, lower production costs, is very suitable for processing of such parts used by SMEs.
