Assessment of Working Conditions of Grinding Wheels in the Grinding Process of Hard-To-Cut Materials

Abstract This study here by presents a method for comparative assessment of grinding wheels during the grinding process of hard-to-cut materials. The method in question consists of carrying out a short grinding cut in plunge grinding kinematics using grinding wheels with a customized macro-geometry upon the active surface. The work presents examples of this method’s efficacy when applied to the process of internal cylindrical plunge grinding with an alloy of Titanium Grade 2, INCONEL alloy 600, INCOLOY alloy 800HT and steel 100Cr6, as a referential material. Grinding wheels with microcrystalline sintered corundum and ceramic bond were used. Experimental tests, which confirmed the usefulness of the presented method in the assessment process of wear mechanisms that take place during the grinding of hard-to-cut materials, as well as the phenomena that cause them, were carried out.
