摘要 为了解微量润滑对不锈钢切削温度的影响,通过304不锈钢的微量润滑车削实验,利用自然热电偶测量切削温度,以切削深度、切削速度、进给量为变化因素,探明不锈钢在干切削、传统润滑和微量润滑(内喷)及微量润滑(外喷)切削条件下的切削温度变化。结果显示,切削温度从高到低依次是:干切削、MQL(外喷)、MQL(内喷)和传统润滑;切削参数越小,MQL和传统润切削滑温度差异越小,切削速度对切削温度的影响要大于切削深度和进给量;MQL系统设置对不锈钢切削温度有明显影响。 In order to understand cutting temperature of stainless steel with minimal quantity lubrication( MQL),a turning experiment in which variables were cutting depth,cutting speed and feed rate was completed. With natural thermocouple,the cutting temperatures of stainless steels were obtained under conditions of dry cutting,traditional lubricity and MQL( inner jet spray) and MQL( outer jet spray). Experimental results showed that cutting temperature descending order was dry machining,MQL( external spraying),MQL( internal spraying) and traditional lubrication;the smaller the cutting parameters, the smaller difference between cutting temperatures of MQL and traditional lubrication. The cutting speed had greater impact on cutting temperature than cutting depth and feed rate; MQL system settings had also affect on cutting temperature of stainless steel.
