Embodiment 1
[0023] The abrasive used in the grinding liquid in the present embodiment is made of the raw materials of the following mass fractions: 0.5 part of conventional diamond abrasive (particle size M0.5 / 1, more than 99.5% of purity), 0.5 part of E-1303 (excellent grade product), 0.5 parts of nano silicon oxide micropowder (particle size 10-100nm, purity more than 99%), 1 part of PEG400MS (high-grade product), 97.5 parts of water; the preparation method comprises the following steps:
[0024] 1) Add PEG400MS to the nano-silica micropowder according to the mass parts, stir and ultrasonically disperse for 20 minutes, ultrasonic power 500W, frequency 40KHz, until the surface of the silicon oxide is fully wetted, and the mixture B is obtained;
[0025] 2) First add E-1303 to conventional diamond abrasives, mix well, then add it to water, ultrasonically disperse (same power and frequency) for 10 minutes, and obtain mixture A for later use;
[0026] 3) Add mixture B to mixture A, stir and...
