ABSTRACT:
The application discloses abrasive finishing chips suitable for use as abrasive media in finishing processes and apparatus for the finishing of parts and workpieces, comprising abrasive grains dispersed in a matrix comprising at least 50% by weight of ground glass bonded together with a substantially uniform bond and of a shape suitable for employment as an abrasive media chip, and a process for the production of such chips which comprises the steps of providing ground glass, causing abrasive grains to be dispersed therein, subjecting the mixture to shape-forming procedure, heating the same to the sintering point of the ground glass, that is, at a temperature between the softening point and the working (fluid) point of the glass but below 1950.degree. F., and allowing the same to cool, thereby to produce abrasive media chips to the type aforesaid.
