KUBONITOVOHO PROCESSING METHOD THIN CYLINDRICAL SURFACES OF WEAR-RESISTANT PARTS ROTATION OF COMPOSITES BASED ON ALUMINUM FOR HIGH-SPEED PRINTING MACHINES

摘要

Kubonitovoho processing method thin cylindrical surfaces of wear-resistant parts rotation of composites based on aluminum for high-speed printing machines fine-grained grinding tools using coolant (coolant). How to apply fine-grained grinding tools wheels of cubic boron nitride (kubonit - CBN) grit 14-28 microns in bakelitno-elastic rubber wheels (Br1). Processing external cylindrical surface of the part made of composite aluminum-based alloys perform on such technological modes: the speed of rotation of the grinding wheel - 35-40 m / s, the speed of the details - 40-60 m / min., The rate of return longitudinal displacement of the details (traverse ) - 45-60 mm / rev. The depth of the layer of metal cutting (cutting depth) - 2.5 m, the active use of coolant (coolant).
