ABSTRACT:
A method and apparatus has been disclosed for grinding contour punch parts. The apparatus is capable of movement on six axes. The main features of the invention include stopping rotation of the part when a flat surface is desired to be ground on the part and moving it directly vertically upwardly with respect to the grinding wheel, thus forming a smooth flat surface on the part. The part is moved on three axes, laterally, horizontally and vertically with respect to the grinding wheel. In addition, a dressing apparatus, movable on two axes, is disposed behind the grinding wheel and maintains a desired surface upon the grinding wheel. The dressing surface may form a ramp surface on the grinding wheel that will create a ramp surface on the finished part.
