摘要：
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. © 2016, Science Press.
