Abstract

The invention discloses an impregnant for impregnated grinding wheels and application thereof in preparing the impregnated grinding wheels. The impregnant is prepared from a solid lubricant, surfactants, dispersants, anti-adhesion addictives and water, wherein the solid lubricants are molybdenum disulfide and paraffin; the surfactants are oleic acid and triethanolamine; the dispersants are sodiumchloride and sodium carbonate; and the anti-adhesion addictives are sodium molybdate and tributyl phosphate. The impregnant is used for preparing the impregnated grinding wheels, and the prepared impregnated grinding wheels have the advantages of improving the grinding state and reducing grinding burn.

Description

(1) Technical field [0001] The invention belongs to the field of precision and ultra-precision machining, and in particular relates to an impregnating agent for impregnating grinding wheels and its application in the preparation of impregnating grinding wheels. (2) Background technology [0002] Grinding is a commonly used mechanical surface processing method, but the grinding heat generated during the grinding process will increase the wear of the grinding wheel, cause the temperature rise of the workpiece, and even cause grinding burns and cracks. In order to reduce the grinding temperature, the way of pouring grinding fluid is usually used for cooling and lubrication. However, due to the high-speed rotation of the grinding wheel, it is difficult for the grinding fluid to enter the grinding area, and it cannot achieve effective cooling and lubrication effects. Especially in some dry grinding occasions and some grinding occasions where the supply of grinding fluid is insuf...
