BACKING PLATES FOR ABRASIVE DISKS

摘要

Accessories for an angle grinder include a resilient backing plate for use with an abrasive disk having shaped ventilating and viewing apertures. The apertures of the backing plate correspond to those on the disk and are shaped so that snagging of the apertures on projections from the work surface is minimized and to facilitate air flow across the work surface during use. This air flow helps in cooling the work and ejecting detritus, so minimising clogging effects. The ventilating apertures also facilitate viewing the work to be sanded through the spinning disk during the abrasion process, so that operator feedback is immediate. The holes also give the backing plate more resilience so that a greater area of the abrasive disk can come in contact with the work and the disk wears more evenly over its abrasive surface.
