Abstract:
1. A grinding wheel for grinding work-pieces comprising: an outer periphery with a first axial end having a first diameter and a second axial end spaced from said first axial end along a centerline axis and having a second diameter; and a plurality of discrete grinding projections for removing material from a work-piece, each of said plurality of discrete grinding projections extending radially outward from said outer periphery and positioned along said centerline axis in spaced relation to one another, said plurality of grinding projections having working heights that vary relative to one another, wherein said working heights of said plurality of grinding projections change at a first rate along a first portion of said centerline axis and change at a second rate different from said first rate along a second portion of said centerline axis adjacent to said first portion, at least one of the first rate and the second rate providing a successive decrease in the amount of the material removed from the work-piece by two or more successive projections, and at least the grinding projection having the shortest working height including an angular grinding profile comprised of substantially straight line segments.
