铰制φ160×760的深孔(50钢件),过去我厂是采用高速钢铰刀。应用这种铰刀,切削速度很低,生产任务很难保证如期完成。后来,我厂学习西安兄弟厂经验,制造了硬质合金深孔铰刀(如图示)。实践证明,将普通车床改装,增加部分辅助装置,利用这种铰刀不仅切削速度可大大地提高,同时也保证了精度和表面光洁度,提高了生产率。如以 Hinge φ160 × 760 deep hole (50 steel), in the past I plant is the use of high-speed steel reamers. The use of such reamers, cutting speed is very low, the production mission is difficult to ensure the scheduled completion. Later, I learned the experience of Xi’an Brothers factory, manufacturing cemented carbide deep hole reamer (as shown). Practice has proved that the ordinary lathe modified to increase some of the auxiliary device, the use of this reamer not only cutting speed can be greatly improved, but also to ensure the accuracy and surface finish, improve productivity. Such as
