轧机辊轴承座的机械加工工艺研究

Study on the Processing Technology of Mill Bearing Chock

轧机辊轴承座结构复杂,轴承孔精度要求高、壁厚差大,不利于进行机械加工.通过先粗后精、先孔后面、先车后磨、不断消除残余应力的加工工艺,解决了相关技术问题.

Mill rolling chock has complicated structure; its hole has high precision requirement and the thickness difference of the hole is large, so the processing technology is very difficult. Through the processing technology which is rough at first and then fine, proces- ses the hole at first and then the face, turns at first and then grinds and continuously eliminates machining residual stress, this study has solved related technical problems.
