The heavy duty vertical lathe machines specifics to large electrical motor industry, large pump valve type industries, transportation industry, as well as engineering machinery, defense industries of some large workpieces cylindrical-type parts with diameter less than 4 m, such as the motor shell, the pump valve shell, wheel hub, to conduct turning processes on end face, internal and external cylindrical surface, but also can use vertical tool carrier with spanning degrees (+/-30 degrees) for the internal and external cone turning processing needs.

Features:

1. The main movement of heavy duty vertical lathe adopts the advanced frequency control system driven by 75Kw variable-frequency motor, through the manual high-low gear shift, so that spindle obtains 2.5 - 40 r / min stepless speed.
2. Table is inlaid with casting zinc, aluminum, copper alloy ZZnA110-5 wearing rail plate to increase the carrying capacity of rail.
3. Spindle of worktable is equipped with two high-precision biserial short cylindrical roller bearings; the inner ring has the taper for adjusting the radial clearance, in order to ensure spindle’s stable working under high-precision. The manipulation buttons of workbench’s startup, braking and jogging are set on the hanging button station.
4. Max. swing angle of vertical tool post is +/- 30°, which is used for turning inner and outer cone face.
5. Right feed movement adopts advanced variable-frequency speed adjusting system.
