摘要

为了改善SiC陶瓷磨削过程中砂轮磨损状态，提高大口径SiC陶瓷光学元件的加工质量和加工效率，本文使用ELID磨削技术进行了SiC陶瓷磨削加工实验。通过和普通磨削过程进行对比分析，研究了ELID磨削技术在SiC陶瓷磨削过程中砂轮磨削表面情况、工件磨削表面粗糙度、磨削力及磨削比方面的优势。实验结果显示：使用ELID磨削技术可以使砂轮表面磨粒在SiC陶瓷长时间大去除量磨削过程中保持足够的锋锐度，磨削过程中磨削力、磨削比均比普通磨削方式下有较大程度的降低，但SiC陶瓷工件磨削表面粗糙度略有增加。表明ELID磨削可以有效缓解砂轮磨损严重导致的磨削力增加、磨削质量下降及使用寿命低的问题，反映了ELID磨削技术在SiC陶瓷长时间大去除量磨削过程中的优势，为大口径SiC陶瓷光学元件的高效高质量加工提供技术支持。

Abstract

Purpose:to improve the grinding wheel wear condition of SiC ceramic during the grinding process

improve the machining quality and machining efficiency of optical elements of large-caliber SiC ceramic

the ELID grinding technology is adopted in the SiC ceramic grinding experiment. Method:based on a contrastive analysis on the common grinding process

a research is conducted on the wheel grinding surface condition

workpiece grinding surface roughness

grinding force and grinding ratio during the SiC ceramic grinding process by adopting the ELID grinding technology. Results:the ELID grinding technology can keep the grinding particles in adequate sharpness after a long-time and wide-removal SiC ceramic grinding process

and compared with common grinding mode

the grinding force and grinding ratio has also been lowered to a much greater extent; but roughness of the SiC ceramic grinding surface increased slightly. Conclusion:it indicates that the ELID grinding technology can effectively alleviate the problems of grinding force increase

grinding quality decrease and short service life caused by severe grinding wheel wear; reflects the advantages of ELID grinding technology in the long-time and wide-removal SiC ceramic grinding process

and such advantages provide technical support for high-efficiency and high-quality machining of large-caliber SiC ceramic optical elements.
