Abstract: Considering the different properties of heat-resisting alloys, such as ZG35Cr25Ni12、OCr25Ni20、ZG40Cr25Ni20 and the newly developed alloys ZGCr50Ni50, OCr56Ni44Ti , and by selecting different cutters, cutters' geometrical parameters and cutting strokes, cutting processing experiments were carried out and the processing parameters of turning, planing and drilling of these alloys were obtained, which have been applied in our production and brought about good effects.
