超声振动辅助磁粒研磨技术是在磁粒研磨的基础上增加了超声波振动功能,可以在短时间内将表面抛光至纳米级别,因其具有辅助研磨效果佳、可控性和适用性好等优点,在越来越多的领域得到了应用。首先对超声辅助磁粒研磨加工技术的发展概况进行了简要介绍,分别从表面粗糙度、材料去除率、显微组织和残余应力等方面进行了重点分析和总结。其次,超声振动工艺参数是影响研磨效果的重要因素,优化选取振幅、振动频率、主轴转速以及磨料粒径等工艺参数可以明显提高研磨效果。此外还要考虑合适的加工时间和加工间隙,从而对复杂曲面进行精密研磨。最后,提出了超声振动辅助磁粒研磨加工技术研究中存在的一些缺陷,并对其未来的发展趋势进行了展望。
Ultrasonic assisted magnetic abrasive finishing technology adds the function of introducing ultrasonic vibration on the magnetic abrasive finishing,which can polish the surface to nano level in a short time.Because it has the advantages of good auxiliary grinding effect,good controllability and applicability,it has been applied in more and more fields.The development of ultrasonic assisted magnetic abrasive finishing technology was briefly introduced.Some analyzis and summarization were made on it mainly from the aspects of surface roughness,material removal rate,microstructure and residual stress.It is shown that,ultrasonic vibration process parameters are important factors affecting the grinding result.Optimizing the process parameters such as the amplitude,vibration frequency,spindle speed and abrasive particle size can significantly improve the grinding effect.In addition,the appropriate machining time and machining clearance should be considered to accurately grind the complex surface.Some inadequacy in the research of ultrasonic vibration assisted magnetic abrasive finishing technology was pointed out,and its future development trend was prospected.
