Abstract
A segmented profiled wheel for grinding a glass or non-metallic workpiece including a segmented abrasive portion formed of a plurality of abrasive segments that are attached to a core of the wheel and method for making same. The plurality of abrasive segments have a cutting surface profile and sufficient abrasive grit to contour and grind the workpiece. Terminal ends of the plurality of abrasive segments are adjacent to one another and the cutting surface profiles align to form a substantially continuous rim of profiled abrasive segments for substantially continuous contact with a workpiece while the wheel rotates. The method includes the steps of forming the plurality of abrasive segments having a metal bonding matrix using automated processes, machining a metal blank to form a core, and attaching the plurality of abrasive segments to the core by laser welding and/or brazing.
