The Effect of the Severity of the Grinding Mode on the Wear Characteristics of Grade 36 Al2O3 and Al2O3 -- ZrO2 Coated Abrasive Belts

A study was made of the wear and performance characteristics of two abrasive minerals used in two very different modes of grinding, a low-pressure constant-load grinding test (to represent relatively mild grinding and finishing applications) and a high-pressure constant-rate test (to represent sever...

Description
Summary:A study was made of the wear and performance characteristics of two abrasive minerals used in two very different modes of grinding, a low-pressure constant-load grinding test (to represent relatively mild grinding and finishing applications) and a high-pressure constant-rate test (to represent severe machining applications). Al2O3 and Al2O3 -- ZrO2 minerals in a resin-bonded cloth-backed construction generally used for most metalworking applications were studied. A variety of techniques were used to analyze and to define wear and grinding performance. These included the measurement of the caliper, energy consumption, mineral utilization and surface profiles of the belts, together with scanning electron microscopy (SEM) observations of belts at various stages of wear. Substantial differences were found for the two mineral types used in the same grinding mode and for the same mineral used in different grinding modes. Data showing mineral consumption during the grinding process and SEM visual identification of key differences in coated abrasive wear are presented.12 refs.--AA
