一、概述磨削烧伤不仅引起表层金属硬度改变,它还会使表层金属中产生不应有的内应力,甚至使工件表面发生微裂纹,这就严重地影响了工件的使用性能,因而,研究磨削过程中烧伤现象发生的规律并寻求防止和控制磨削过程中烧伤现象发生的途径,一直是磨削加工表面质量 First, an overview Grinding burn not only caused by changes in the surface hardness of the metal, it will also make the surface of the metal in the unwanted internal stress, and even micro-cracks on the surface of the workpiece, which severely affected the performance of the workpiece, and therefore, research The law of the burn phenomenon in the process of grinding and the way to prevent and control the burn phenomenon in the grinding process has always been the quality of the grinding surface
