摘 要： 在难加工材料的加工过程中，由于所消耗的能量大部分以热能的形式积聚在加工区，若不能及时将这些热量疏导出去，将导致加工区温度的急剧升高，并很快造成工具的失效或零件的报废。为达到及时冷却的目的，本文从这种现状出发，基于绿色制造的理念，提出了利用无污染的低温冷风来实现机械冷却的目的。实验结果表明，在微加工中低温冷风冷却比传统的润滑液冷却油较好的效果。 关键词 ：低温冷风 表面粗糙度 圆度 Application Of Cryogenic Wind Cooling Technology In Grinding Process Cai Yulin Zhanghua Liu Yefeng Zhao Huanhuan Institute of Refrigeration and Cryogenics, University of Shanghai for Science and Technology, Shanghai 200093 Abstract : During the machining of difficult-to-machine materials, most of the consumed energy converts to heat and accumulates in the machining zone. If the heat cannot betransferred out in time, the temperature in the machining zone will rise quickly and make tools disabled and workpiece useless. Here an original idea about Cryogenic wild cooling technology based on the conception of Green Manufacturing is put forward in this paper. The experimental measurement results indicate that the effect of Cryogenic wild cooling in micro-processing was better than traditional liquid cooling.
