Super-hard abrasive grinding wheel with head face having abrasives in phyllotaxis arrangement and production method thereof

Abstract

The invention discloses a super-hard abrasive grinding wheel with a head face having abrasives in a phyllotaxis arrangement, comprising a grinding wheel basal body. The working surface of the grinding wheel basal body is provided with a plurality of abrasive particles or abrasive particle groups fitting with the biological phyllotaxis theory. The plurality of abrasive particles or abrasive particle groups are fixed on the grinding wheel basal body through a metal bonding agent. According to the biological phyllotaxis theory, the plurality of abrasive particles or abrasive particle groups forma plurality of anticlockwise leaf column line grooves and a plurality of clockwise leaf column line grooves. By means of the invention, the arrangement of the abrasive particles or the abrasive particle groups on the working surface of the grinding wheel fits with the H.Vogel model of the phyllotaxis theory so as to realize the physiographic controllability of the working surface of the grinding wheel. Nickel or nickel-cobalt alloy is adopted to serve as the bonding agent so as to fixedly bond the abrasives. The grinding wheel is capable of controlling the cutting state of the abrasive particles in a grinding region, the cooling liquid distribution and the grinding temperature distribution, and achieving lowest grinding force and specific energy consumption, lowest grinding temperature and burn, lowest abrasion of the grinding wheel, optimal work-surface surface integrity, and the like. The comprehensive grinding performance of the head face grinding of the super-hard abrasive grinding wheel is improved.
