【Abstract】 This cutting machine is used to cut scrap steel mainly. Its structure is compact.The machine is automatic highly and operatic easily. VVVF(vary voltage vary frequency) is used in velocity modulation and the velocity range is very wide. So it can cut different thickness scrap steel. Its cutting route is very long in horizontal and vertical direction. The paper introduces the constitution and working principle in mechanic and electric of the automatic cutting machine. The application of a SIMENS inverter is described mainly. 更多还原
