Abstract
A diamond-set insert carrier tool for dressing, chamfering, smoothing or polishing machines which comprises a body or support of thermoplastic material, in the active surface of which there are provided cavities able to receive diamond-set abrasive inserts or bodies and retain them substantially flush with said active surface by interference, said interference being between 0.1 and 0.3 min.
Claims5
