CNC heavy gantry boring and milling machining center consists of a fixed workbench, a moving gantry and a beam. The main structural parts are made of high-strength cast iron and phenolic sand, which has good shock absorption and thermal stability. The structure of the whole machine is characterized by high rigidity and high reliability. It is suitable for the processing of heavy-duty and extra-heavy basic parts in metallurgy, railway, heavy machinery, shipbuilding, automobile and other industries, especially for CNC machining of various planes, curved surfaces, space surfaces and heavy holes. The machine has good rigidity and high stability to ensure long-term work.
