我厂在生产解放牌汽车120曲轴时,用C620车床钻削φ48毫米孔。过去用机械油掺煤油做冷却油,在加工过程中产生大量的油烟,严重影响工人的健康,妨碍正常操作。81年我们采用MoS_2蜡笔代替油料作切削润滑剂,通过一年多的使用,证明它可取代机械油和冷却油对钻头、车刀、铣刀、丝锥等刀具加工工件部位的润滑,节约油料,使用方便,并没有油烟 I plant in the production of Jiefangbei car crankshaft 120, with C620 lathe drilling φ48 mm hole. In the past, kerosene was blended with machine oil to make cooling oil, which produced large amounts of smoke fumes during processing, seriously affecting workers’ health and impeding normal operation. In the past 81 years, we used MoS_2 crayon instead of oil as the cutting lubricant. After more than one year of use, we proved that it can replace the mechanical oil and cooling oil to lubricate the parts of the tool machining parts such as drill bits, turning tools, milling cutters and taps, Easy to use, no fumes
