The machine tool castings are cast in high-strength cast iron and the structural design uses a high-strength, high-rigidity box structure. The rail surface and the workbench are all quenched and hardened by guide rails. The bed is subjected to two artificial aging treatments to ensure that the machine tool has good stability, high strength, and stable and reliable accuracy. It is mainly applied to the processing of board, disc, mould and small shell complex parts. Can complete milling, boring, drilling, tapping and cutting threads and other processes.
