细长轴的外圆表面,可以利用滚压加工来提高其表面光洁度、精度和表面质量,使工件的工作性能,如疲劳强度、耐磨性和耐腐蚀性均有显著改善,并且使用寿命也得到提高。但是,滚压过程经常产生的缺陷,却严重影响着滚压质量,甚至造成不良的工作效果。因此,研究分析滚压缺陷的成因及防止其产生具有重要的意义。下面结合工作中的体会谈谈自己的一点看法。
The outer surface of the elongated shaft can be rolled to improve its surface finish, precision and surface quality, so that the workability of the workpiece, such as fatigue strength, wear resistance and corrosion resistance are significantly improved, and the service life Be improved. However, the rolling process often produces defects, but it has a serious impact on the rolling quality, and even cause poor work results. Therefore, it is of great significance to study and analyze the causes of rolling defects and prevent their occurrence. The following combination of work experience to talk about their own point of view.
