Title:
ABRASIVE WHEELS WITH WORKPIECE VISION FEATURE
Document Type and Number:
WIPO Patent Application WO2002045908
Kind Code:
A8
Abstract:
Abrasive grinding wheels having an irregular (i.e., gapped) perimeter shape and/or holes extending therethrough permit one to view the surface of a workpiece being ground in conventional surface finishing, snagging and/or weld blending operations. The grinding wheels may each include one or more gaps disposed in spaced relation about the otherwise circular perimeter of the wheel. Holes also may be provided in addition to, or in lieu of, the gaps, and similarly spaced equidistantly about the wheel. The gaps and/or holes may be configured in many diverse shapes. Gap and hole positions may be selected so as to retain the balance of the wheel. Advantageously, when the wheels are rotated about their axes, one is able to monitor the condition of the surface of the workpiece as it is being abraded, without removing the grinding wheel from the surface.
