为了提高生产率与充分发挥硬质合金的作用,在我们加工轴承压帽螺纹(M47×2)的时候,革新并采用了机械夹固式内螺纹车刀(图1)。实践证明,应用这种刀车,使得生产率与表面光洁度都可大大地提高。如:在利用这把刀加工M47× 2螺帽的螺纹时,采用n=600转/ In order to increase productivity and give full play to the role of cemented carbide, we modified and adopted a mechanically-clamped internal thread turning tool (Figure 1) as we machined the bearing cap thread (M47 × 2). Practice has proved that the application of this knife car, making the productivity and surface finish can be greatly enhanced. Such as: In the use of this knife processing M47 × 2 nut thread, the use of n = 600 rev /
