Heavy-duty Conventional Universal Lathe

This machine is characterized by its large power, high rigidity, high spindle speeds in a wide variety and is suitable for heavy and high speed cutting operations. The machine is suitable for facing , turning external and internal cylindrical surfaces as well as cutting of a wide range of different metric, English, module and diametral pitch threads, It can be used for drilling, trepanning and boring operations as well. Braking and rotating-direction change of spindle is controlled by hydraulic power with sensitive and reliable performances. By the manipulation of a push button spindle speed change can be made to a higher or lower step without stopping the machine. Lubrication in the headstock is effected by forced pressure oil while spindle speed ranges are furnished for selection by user when placing order. The apron is provided with a safety device to protect the machine against overloading. The top slide may be operated by power for cutting short taper surface. The combination of longitudinal feed of the saddle and feed of the slide facilitates the cutting of a long taper surface on this machine. All guideways on the bed are casehardened to prolong their service life. The centralized levers can be easily and conveniently operated.
