重庆汽车发动机厂在一台单柱立式铣床上精铣6140型汽缸体平面时,能够得到凸凹花纹的加工表面,如图1a所示,图中一块块明暗交替的花纹,类似于钳工用手工刮研表面时形成的刮花面。据了解,国内只有少数几台设备能铣出这样的表面,长期来虽然有很多单位对这种现象很感兴趣,但对其工艺机理还不能作深入的分析。作者在对整台设备和现场加工情
Chongqing Automobile Engine Factory in a single-column vertical milling machine finishing 6140-type cylinder body plane, can get the concave and convex pattern of the processing surface, shown in Figure 1a, a block of light and dark alternating patterns, similar to the fitter manually Scratch the surface of the formation of scratched surface. It is understood that only a few domestic equipment can mill such a surface, in the long term although many units are very interested in this phenomenon, but its technology can not make in-depth analysis of the mechanism.
