Refinement of the procedure to determine durability of abrasive materials

Material performance as well as its purpose and way of use depend on its physical and mechanical properties. The Shlif device based on a small-sized friction machine was used to test durability of abrasive materials. The conditions and procedure of such studies were refined. Boron carbide with grain size F 80, sample weight of 0.04 g, specific sample load of 0.01 MPa was used as an abrasive body. According to the test results of the samples, the wear time is 5 minutes. Since the results of studying the sample wear are sensitive to process factors and tool parameters, and there is a correlation relationship with the field test results, the results can be used for rapid quality analysis of abrasive tools in the process of production and operation, as well as for designing of new types of tools.
