CNC lathe heavy-duty horizontal lathe is a new product developed on the basis of large horizontal flat bed lathe. The bed is re optimized, the overall weight is increased, the pallet is lengthened, widened and thickened, and the processing efficiency, accuracy and rigidity are better than CNC lathe. Adopting a semi protective structure and equipped with a wide range 980TDi system. The main transmission for turning is a manual four speed system with continuously variable speed within each gear, providing excellent positioning accuracy and repeatability. Optimized design of headboard box, suitable for turning of disc and shaft parts, capable of processing straight lines, arcs, metric and imperial threads, and multi head threads, suitable for turning complex shapes and high precision requirements
