我厂生产的柱塞式高压油泵中,有一铜缸体,均有一圆球窝。其半径R100～200mm,深约5mm,中心处有小孔。根据圆片形在旋转一周时刚好是形成一个圆球的原理,我们设计了如图1所示的圆片刀车球窝方法。此法加工较方便,成本较低。我们对球窝作了试验,加工情况比较理想,已在生产中发挥作用,取得了明显的经济效果。对于较大圆片刀可考虑改为组合式结构较理想,并需考虑刀架有足够的强度和刚度,否则切削时容易振动。对小圆片刀可采用W18Cr4V整体淬火。硬度为HRC60～
I plant the production of high-pressure piston pump, a copper cylinder, have a ball-nest. The radius of R100 ~ 200mm, about 5mm deep, there are holes in the center. According to the principle of forming a sphere just when the wafer shape is rotated by one week, we designed a wafer cutter ball-socket method as shown in FIG. 1. This method is more convenient processing, lower cost. We have tested the ball socket, processing ideal, have played a role in production, and achieved significant economic results. For larger disc knife can be considered to be more ideal combination structure, and to consider the tool holder has sufficient strength and rigidity, or cutting vibration easily. On the small blade can be used W18Cr4V overall quenching. Hardness of HRC60 ~
