Conditions for energy capacity reducing of treatment at diamond grinding

Abstract

The main parameters of diamond grinding were determined analytically, taking into account the formation of steady cutting relief on the working surface of a wheel. This made it possible to substantiate the conditions for reducing the energy intensity of processing (conditional cutting stress), which consist in the use of both multi-pass grinding and high-performance depth grinding at a relatively low workpiece speed. It is shown that grinding with diamond wheels on metal bonds leads to an increase in the intensity of processing. Therefore, it can be reduced by increasing the grain size of the wheel, as well as by applying continuous electroerosive dressing or diamond spark grinding, which allow for the bulk destruction of grains and their timely removal from the working surface of the wheel, which maximizes the use of significant technological capabilities of diamond wheels on metal bonds with a significant increase productivity and quality of processing.
