Grinding wheel, grinding machine and method for dressing a grinding wheel

Abstract

A grinding wheel (24) suitable for electro-erosive dressing has a rotating axis and a grinding surface (142) with a macroscopic matrix (154). The grinding wheel (24) is rotatable about the rotating axis. Abrasive grains (156) are embedded in the macroscopic matrix (154). The macroscopic matrix (154) is conductive. The abrasive grains (156) have a conductive microscopic matrix (164) in which cutting particles (166) are embedded. A grinding machine uses such a grinding wheel (24) suitable for electro-erosive dressing. A method is used to dress such a grinding wheel (24) by wire electro-erosion.
