国内重型数控机床的现状及发展趋势

Status and Development Trend of Domestic Heavy-duty CNC Machine Tools

重型数控机床是能源、交通等行业超重、超大零部件的工作母机,制约着这些行业的发展。结合国内重型数控机床设计与制造的挑战,以数控七轴五联动螺旋桨加工重型车铣复合机床CKX5680为例,介绍了重型数控机床的技术突破与创新;介绍了已投入使用的多型国产重型数控机床及其使用中遇到的问题;对重型数控机床的发展趋势进行了展望。

Heavy-duty CNC machine tools were the machine tools for overweight and oversized components in energy,transportation industries and so on,which restricted the development of these industries.Combining the challenges of the design and manufacture of heavy-duty CNC machine tools in China,the technological breakthroughs and innovations of heavy-duty CNC machine tools were introduced with the example of a CNC seven-axis five-link propeller machining heavy-duty turning and milling machine tool CKX5680.The on-service domestic heavy-duty CNC machine tools and the encountered problems in the machining prosesses were proposed.Future development trends of heavy-duty CNC machine tools were prospected.
