1. The giant lathes bearing 32 tons . It is suitable for external and internal cylindrical surface , oil grooves , cutting off , boring hole , turning inside and outside conical , cylindrical and dis-cold parts to axes parts of different materials with high-speed steel and hard alloy steel cutters , and it can turn different kinds of screw thread with length short of 600mm with upper too-post (via change gears).

2. The giant lathes 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 guideway surface (1600mm), good rigidity , strong anti-vibration ability ; It is accurate ground by import guideway grinder , which guarantee the high precision and best receptivity .

3. The giant lathes master drive institution is dragged by 75kw DC electric motor , and it adopts the mode of speed regulation of adjust magnestism commix with adjust pressure . Total ratio of speed 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, thereby made the master axes obtain infinite class speed variation scope 0.8-160 r/min.

4. 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.
