Abstract
The present invention uses the artificial carborundum, natural diamond powder, white alundum, brown alundum or cubic boron nitride, chromic oxide and ferric oxide as abradant. Two kinds or three kinds of kerosene, spindle oil and engine oil are used to prepare emulsion in accordance with specific proportion. Said emulsion and abrandant whose graininess is between 100 micro m.-0.08 microm are undergone the mixed milling to make them into grinding agent and it is filtered for using. Said invention implements said processing technology on vertical or horizontal ordinary steel ball processing equipment or special equipment. The diameters of the processed ceramic balls are 2-60 mm. The technical index can come up to and surpass the accuracy of ISO 3290 and GB 308-84 G16-G5 level.
