METHOD OF PRECISION DIAMOND PROCESSING OF HOLES OF BEARINGS FROM WEAR-RESISTANT COMPOSITE MATERIALS BASED ON ALUMINUM FOR PRINTING MACHINES

摘要

Method of precision diamond processing of holes of bearings from wear-resistant composite materials based on aluminum for printing machines for fine-grained grinding tools using coolant (coolant). Treatment of surface friction parts holes carry the grinding wheel based on synthetic diamond (AU), 14-50 micron grit at bakelitno-rubber bond and surface treatment performed by such technological modes: rotation speed parts - 35 - 40 m / min. , the speed of the diamond (AS) circle - 40 - 55 m / s, the speed of movement of the tool along the longitudinal axis of the hole surface processing of 1.5 - 3.5 m / min. cutting depth - 5 - 20 microns.
