磨加工时的烧伤现象严重地影响着加工另件的耐磨性和疲劳强度,有了这种现象就不能达到采用热处理和磨加工的预期目的。本文首先根据热传导理论导出计算磨削区温度的公式,提出磨削区温度的计算方法,对磨加工烧伤现象的物理本质进行了分析。其次介绍了作者在哈尔滨工业大学实验室内进行实验的结果。最后根据理论分析和实验结果提出从选用磨削用量改进冷却方法等方面避免烧伤现象的意见。 Burning wear process seriously affect the processing of other pieces of wear resistance and fatigue strength, with this phenomenon can not achieve the intended purpose of heat treatment and grinding. In this paper, the formula for calculating the temperature of the grinding zone is derived based on the theory of heat conduction. The calculation method of the temperature in the grinding zone is proposed, and the physical nature of the burn phenomenon is analyzed. Secondly, it introduces the author’s experiment in Harbin Institute of Technology. Finally, according to the theoretical analysis and experimental results, we put forward the suggestion of avoiding burn phenomenon from the selection of grinding amount to improve the cooling method.
