目前有关锡青铜加工的参考资料很少,特别是关于薄壁铜套拉削的文献更少,各厂所设计拉刀的结构和几何参数很不一致。我厂拉削各种衬套所用的拉刀,由于结构和几何参数不合适而引起啃刀、撕裂、拉偏和光洁度低等缺陷,甚至有个别零件的加工只得放弃拉 At present, there are few reference materials for the processing of tin bronze. In particular, the literature on the thin-wall copper sleeve broaching is less, and the structure and geometric parameters of the broach designed by each factory are very different. I broach broaching used in a variety of bushing, due to improper structure and geometry parameters caused by eating knives, tearing, pull and poor finish and other defects, and even the processing of individual parts have to give up pulling
