Abrasive particle jet assisted ultrahard fine abrasive material grinding wheel ultraprecise grinding method

Abstract

The invention belongs to the technical field of grinding, and discloses an abrasive particle jet assisted ultrahard fine abrasive material grinding wheel ultraprecise grinding method. The precise grinding process of an ultrahard fine abrasive material grinding wheel is assisted by abrasive particle liquid jet flow with ultrafine particle size; the online sharpening and the fine grinding edge equal-height finishing are performed on the working surface of the ultrahard fine abrasive material grinding wheel in the grinding process by using the strength difference of ultrahard abrasive materials,general abrasive materials and bonding agents; and the ultraprecise grinding is realized under the grinding effect of a sharp equal-height grinding edge of the ultrahard fine abrasive material grinding wheel. The method realizes the sharpening and the equal-height finishing of the grinding edge of the ultrahard fine abrasive material grinding wheel, effectively solves the technical difficulties ofthe online sharpening and the grinding edge equal-height finishing of the surface grinding edge of the ultrahard fine abrasive material grinding wheel, and achieves an active effect on improvement ofthe grinding surface quality. The method achieves obvious advancement, and achieves prominent academic and actual application value on promotion of the grinding technology development.
