ANALYTICAL DETERMINATION OF CONDITIONS FOR PRODUCTIVITY IMPROVEMENT OF DIAMOND GRINDING

Abstract

The analytical dependences for definition of processing productivity when grinding by diamond wheels on metal bonds with the accounting of linear wear of the grain which is the most acting over the level of bond are given on the basis of probability-theoretic approach.. Conditions of electroerosive dressing with providing the optimum cutting relief of diamond wheel are defined. A high-performance process of longitudinal external cylindrical diamond grinding of fast-cutting and hard-alloy multiedge tools (mills, reamers, core drills, etc.) is developed with high quality of processing and renting allowance to 1,2 mm per side in one pass.
