近年来,冷辗扩工艺跃居环形件加工之首位,这不仅象征着对传统切屑工艺的排挤,更意味着从全新的角度来安排工艺流程。 当然,通过冷辗来扩径并成形环形件的设想早在一个世纪前就有了,只是在20年前当轴承工业作为第一个潜在用户在全球范围开始研究这个课题时,冷辗工艺的复兴方告开始。 最初的乐观主义因为当时的技术只能做到辗扩和成形达不到精度 In recent years, the cold rolling technology ranks first in the ring processing, which not only symbolizes the exclusion of the traditional chip technology, but also means that from a new perspective to arrange the process. Of course, the idea of ​​expanding and forming rings by cold rolling was as early as a century old, only 20 years ago when the bearing industry, as the first potential user, began researching this topic on a global scale Revival party began. The original optimism because the technology can only be done rolling and forming precision
