摘要: 为了验证微量润滑技术对刀具磨损及工件表面粗糙度的影响,研制出一套微量润滑系统,利用压缩气体流经的截面变小所产生的压强差来吸取箱体中的液体,并传输到喷嘴进行雾化.将其应用在高强度钢铣削加工中.试验结果表明:相对于干切削和传统浇注冷却,微量润滑技术具有明显的优势,它可有效地减小刀具磨损,并将工件表面粗糙度控制在较低的水平,尤其在高转速、大切深、快进给加工中,同时其还具有结构简单、冷却液用量小、对环境污染小等优点.对试验结果进行了初步分析.

Abstract: In order to validate the influences that MQL(minimal quantity lubrication)brings to the tool wear and surface roughness, a MQL system was developed. It used the difference of pressure that caused by the compressed air flow through the decrescent areas to imbibe the cooling fluid in the box, and transported it to the nozzle for atomizing. The application in milling high-strength steel was also investigated. The experiment indicates that MQL has obvious predominance compared with dry and traditional cooling method, it can efficiently reduce the tool wear and keep the surface roughness at a low level, especially in the machining of high spindle rotating speed,big depth of cut and fast feed rate. It also has the characteristics such as the simple structure, the less dosage of cooling fluid and the less pollution to the environment. The experimental results were analyzed elementarily.
