Application: Universally applicable for pendulum grinding processes, which significantly reduces the frequency of wheel changes in daily operation. Can be used on all commercially available grinding machines for tool and die making and machine tool building, e.g. Jung, ABA, Blohm, Elb, Magerle, Ziersch&Baltrusch, Geibel&Hotz, Jones&Shipman. Cooling with emulsion is necessary, good lubrication on long-chipping materials is absolutely necessary. Note: Profile surface grinding wheels available on request.
