Beschreibung
Zusammenfassung:	A system for electrode dressing including a cutter with a rim and a center land supported on the rim by a number of flutes defining openings between the flutes. The flutes and the center land define a cutting profile of the cutter. The cutter is configured to rotate about an axis passing through the center land. Cutting edges are disposed on the flutes and are made of a first material having a Vickers hardness (HV) of at least 850 HV, overlaid by a second material having a Vickers hardness of at least 3200 HV. The cutter profile comprises a face cutting profile extending radially outward from the axis that is disposed at an angle of less than six-degrees relative to a radial normal of the cutter.
