摘要
介绍了高强度钢材料的应用现状,以及其切削加工特性;探讨了高强度钢材料的切削加工问题和35CrMnSiA的化学成分与力学性能。针对干切削和冷却液浇注切削的不足,通过对采用液氮低温切削加工高强度钢零件方法的研究,设计了低温液氮切削与干切削和冷却液浇注切削的对比试验。试验结果表明,这种方法能提高了工件表面的精度,延长了刀具的使用寿命,可省去冷却液和废液,有利于实现清洁生产模式,符合绿色制造的要求。
It introduced the application status of high strength steel material,and its cutting characteristics;discussed the machinability problem of high-strength steel material and the chemical composition and mechanical properties of the 35CrMnSiA.Aiming at the shortage of dry cutting and cooling liquid pouring cutting,through the research on the method of liquid nitrogen cryogenic machining high strength steel parts,the contrast test of the cryogenic liquid nitrogen cutting and dry cutting and cooling liquid pouring cutting is designed.The results showed that,this method can improve the accuracy of the surface of the workpiece,prolong the service life of the cutter,can save cooling liquid and waste liquid,conducive to the realization of clean production mode,and comply with the requirements of green manufacturing.
