Collapse Lathe type Ⅱ is specially used for heat treatment of optical fiber prefabricated tube-rod. It is suitable for hot working processes such as melting, drawing, taper drawing, nozzle and polishing of quartz tube-rod with outer diameter below φ 50mm. The machine tool bed is cast with cast iron as a whole, which can effectively reduce the process error caused by mechanical interference. The simplified machine tool bed configuration, lathe electromechanical system and air supply system all adopt internationally renowned brand accessories, which comprehensively improve the reliability and safety of the system. It saves more space and air source, and is economical and practical.
