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.
In order to verify the impact of micro-lubrication technology on tool wear and surface roughness of the workpiece, a set of micro-lubrication system was developed to draw the liquid in the tank by using the pressure difference generated by the smaller cross-section of the compressed gas, The results show that compared with dry cutting and traditional casting cooling, trace lubrication technology has obvious advantages, it can effectively reduce the tool wear, and the workpiece surface roughness It has the advantages of simple structure, small amount of coolant, little pollution to the environment, etc. The preliminary analysis of the test results is carried out.
