Experimental research of ELID grinding on SiC ceramics based on grinding wheel wear
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.
