Abstract

This article presents results of experimental tests of internal cylindrical traverse grinding in which the total machining allowance is removed in a single pass. Grinding wheels with zone-diversified structure made on basis of abrasive grains from Al2O3 were used in the process. Such tools are characterized by different construction of rough and finish grinding zones. Moreover, conic chamfer is shaped on their active surface that allows for even distribution of machining allowance on the grinding wheel surface. What is described in the hereby work is a device for precise shaping of conic chamfer on the grinding wheel active surface (GWAS). The work also presents results of tests whose aim was to determine the influence of grinding wheel macrogeometry on the process of internal cylindrical traverse grinding of internal cylindrical surfaces made from steel 100Cr6. Changes of selected parameters of the machined surface geometric structure (Ra, Rz, RSm, Rdq and RTp) and values of the grinding power P were analyzed. It was proved that the greater the conic chamfer width, the better the results.
