并条机牵伸罗拉斜齿顶面CBN砂轮磨削加工

在分析罗拉斜齿顶面棕刚玉砂轮磨削缺陷的基础上,提出用立方氮化硼(CBN)砂轮代替传统的棕刚玉砂轮进行磨削加工;确定CBN砂轮的构造特性和结构尺寸;设计CBN砂轮金刚滚轮修整装置;并对CBN砂轮修整参数进行深入分析研究。使用情况表明:采用CBN砂轮对罗拉斜齿顶面进行磨削加工,其精度和表面质量均有很大的提高,磨削表面无烧伤现象;砂轮的耐用度大大提高,其使用寿命是棕刚玉砂轮的50倍以上。

CBN wheel grinding on the rollers skew tooth top-surface of drawing frames draft

Based on analysis of the grinding shortcomings associated with brown emery wheel of the rollers skew tooth top-surface,a method was proposed,which used CBN grinding wheel in substitution for traditional brown emery wheel.The structural features and size structure of CBN grinding wheel were determined and a set of diamond wheel trimming device for the CBN grinding wheel was designed.An in-depth research on the CBN wheel′s dressing parameters was performed.Practical use indicates that CBN wheel grinding the top-surface of rollers skew tooth has made the grinding precision and surface quality greatly improved,no phenomenon of grinding burn.The endurance of CBN grinding wheel has been enhanced significantly and the life of it is more than 50 times of that of the brown emery wheel.
