The CNC gantry machining center has high rigidity and reliable structural design. It not only has the corresponding strong cutting ability, but also can meet the processing of precision parts. The product is suitable for metallurgy, railways, heavy machinery, ships, power generation, automobiles, aerospace, printing, molds and other industries. It can work normally and continuously under the environmental conditions specified in the technical documents with stable precision. It is mainly used for the processing of heavy and super heavy parts, especially for CNC processing of various planes, curved surfaces, space curved surfaces and holes of ferrous and non-ferrous metals with large weight and long workpiece length. It is widely used to complete the rough and fine processing of various complex parts such as plates, boxes and racks in the machinery manufacturing industry. The machine tool can complete curved surface processing and rigid tapping. The addition of an accessory milling head can complete the processing requirements of five faces. And according to the customer’s processing technology requirements, the accessory milling head can be added according to the processing technology of the workpiece, and a five-faced body can be processed in one clamping.
