Abstract

The invention is applicable to a grinding fluid used in bronze anchoring agent super hard abrasive grinding wheel high speed electrolyzing dressing grinding. Its weight percentages are base fluid 87-89, sodium nitrite 9-11, saltier 0.25-0.40, disodium hydrogen phosphate 0.5-2.0, borax 0.1-0.2, propanetriol 0.28-0.32, and tributyl phosphate 0.1-0.3. The base fluid is normal water base high speed grinding fluid. It has great electrolysis film forming capability; the descending of the electrolysis current is quick; stable current is small; and the good oxide film can be formed at the superficial of the grinding wheel. The grinding cutter is as 3 / 4-2 / 3 of the common grinding; working superficial roughness is as 4 / 5-3 / 4.

Description

technical field [0001] This invention relates to grinding fluids for precision and mirror grinding of advanced ceramics. Background technique [0002] The E1electrolytic In-process Dressing (ELID for short) technology is a new continuous dressing grinding method proposed by the Japanese scholar Omori in 1987, which has been successfully applied to the precision and mirror grinding of advanced ceramics. . At present, its application scope is expanding day by day. When using this method for grinding, the grinding wheel is connected to the positive pole of the power supply through a brush, and a cathode with good conductivity is made according to the shape of the grinding wheel to connect with the negative pole of the power supply. There is a certain gap between the electrode and the surface of the grinding wheel, and the nozzle The grinding fluid with electrolytic effect sprayed out of the grinding wheel enters the gap between the electrode and the surface of the grinding wh...
