Proprietary technologies ensure the ideal mix of speed, surface finish and reduced electrode wear. This video demonstrates two methods of high-speed rib machining being achieved. The first method applies HS-Rib and HyperCut technology using a 0.020 inches (0.5 mm)-wide graphite electrode with one-degree draft angle in H13 tool steel. With a jump speed of 20 m/minute and 1.5G acceleration, rough-cut machining is performed to produce a 0.750 inches (19 mm) wide die/mold support rib feature The next example illustrates high-speed side-burn vector machining in H13 tool steel with HyperCut technology. Machining is performed using a graphite electrode with a tapered-nose star rib geometry measuring 0.400 inches by 0.400 inches with a 0.03-inch-wide “plus” shape (10 mm by 10 mm by 0.7mm wide) and 0.5-degree draft angle. The side burn operation is performed in the X-axis direction with a jump speed of 5 m/minute and 0.1G acceleration.
