METHOD OF DIAMOND ABRASIVE PROCESSING WITH SUN-AND-PLANET MOTION Russian patent published in 2011 - IPC B24B33/08 

FIELD: process engineering.

SUBSTANCE: invention relates to machine building and may be used in diamond abrasive finishing, for example, for honing holes. Body lengthwise grooves accommodate honing stick holders with diamond sticks arranged outside. There are at least two spacer bars per every stick holder arranged to slide in body radial dead bores made at acute angles to plane perpendicular to lengthwise axis. Said spacing bars are arranged to reciprocate along axes of said bores to have one spherical face that thrust against stick holder bore spherical bottom. Compression helical coil spring acts on opposite face of bars. Body may revolve, displace axially and perform sun-and-planet motion relative to additional axis offset relative to main lengthwise axis.

EFFECT: device features simple design, allows higher processing efficiency and tool longer life.
