This is type of universal lathe which bearing thirty-two Ton, it applicable to turning external and internal cylindrical surface, oil grooves, cutting off, boring hole, turning inside and outside conical, cylindrical and discoid parts to axes parts of different materials with high-speed steel and hard alloy steel cutters, and it can turning different kinds of screw thread which length short of 600 mill metric with top knife carrier.

This machine tool bed structure is integral BOX-shaped and three strip rectangle guide way, and it is found once by high quality cast iron(HT300), through two-aged processing , stability is good; Width guide way suiface (1600mm),good rigidity ,strong anti-vibraton ability;it is accurate ground by import guide way grinder, which guarantee the high precision and best receptivity of machine tool.

The machine tool master drive institution is dragged by 75KW DC electronmotor ,and it adopt the mode of speed regulation of adjust magnetism commix with adjust pressure, total ratio of speed regulation is 1:22.2 , the institution’s speed regulation progression is third class , the syntheses speed regulation ratio of mechanism and electric is 1:200, there by made the master axes obtain infinite class speed variation scope 0.8-160r/min.

Input system is connected with naked bar and master drive , made the input directness relation to speed of master axes, feeding amount selection is facility.
