摘要

Conditions for improving the efficiency of external round grinding are considered. Patterns of formation of non-uniform abrasive impact on the treated surface within the limits of technological primitives of initial contact, input, output and steady grinding are revealed, and corresponding analytical expressions are determined. Conditions have been established to ensure uniform abrasive action by adequately increasing the cutting ability of each conventional strip of the working surface of the wheel, reducing their grain size depending on the number of repeated encounters with the already cut surface. A abrasive wheel of different grain size was developed to improve the efficiency of the process by combining rough (F46), finish (F54) and fine grinding (F60) in one technological transition and is protected by the corresponding patent Pat.I 1012,0009. Comparative analysis showed that when grinding with a wheel of a different grain size, there is a threefold increase in surface stationarity. Practical recommendations have also been developed to determine the rational value of the initial contact area.
