若干年前,为了对某高温合金材料进行性能测定,需大量的试样,但由于实验室只有一台车床而无外圆磨床,为了使试样达到规定的光洁度,我们着手将滚珩加工的原理应用到试样精加工上来。具体做法是:先将试样在车床上车削加工成形,留下一定的余最,然后利用车床再加上一套简单的滚珩辅助装置进行滚珩加工。结果出乎意料地好,经过滚珩的试样,不仅光洁度达到规定的要求,而且消除或减小了车削时遗留下来的形状误差。于是,我们对这种精加工试样的方 A number of years ago, a large number of samples were required to measure the properties of a superalloy. However, since the laboratory only had one lathe and no cylindrical grinder, in order to achieve the specified finish of the sample, we set out to roll- Principle applied to the sample finishing. The specific approach is: first sample in the turning lathe forming, leaving some of the most, and then use the lathe plus a simple roll Heng auxiliary device for roller honing. The result was surprisingly good, with a roll-over specimen that not only achieved the required finish but also eliminated or reduced the shape error left behind during turning. So, we are on the side of this finishing sample
