Wear of diamond dressing tools at vibromechanical type of dressing abrasive discs

Resumo

The wear and strength characteristics of the mounted diamond have been studied during the application of a new type of dressing for abrasive wheels. The diamond dresser is mounted on an elastic base in order to perform oscillations during dressing under the action of abrasive grain impacts. The experiments were aimed at determining the value of the diamond grain wear of the dressing tool, the number of the treated samples up to the forced substitution of the dressing tool, and the lifetime of the dressing tool at vibromechanical and common types of dressing. The tests have shown a significant increase in the resistance of the diamond dressing tool in the case when the vibromechanical method was used, in contrast to a common dressing by a mounted diamond wheel.
