S1302-2-2 Performance of metal-bonded diamond wheel in ultrasonically assisted internal grinding of small holes

Abstract

This study aims to develop an ultrasonically assisted grinding technology for internal precision machining of small holes such as those formed in a fuel injector for an automotive engine. In the previous work, an experimental apparatus for internal grinding was established by installing an ultrasonic spindle onto a commercial internal grinder. In this work, a metal bonded diamond wheel is employed in the ultrasonically assisted internal grinding of small holes due to its excellent abrasion resistance. This report describes the performance of this kind of wheel in actual grinding experiments in details.
