Pipe Threading Lathe
Model: STC

Introduction of Pipe Threading Lathe:
Cone-roller bearing is adopted for higher spindle rigidity.
Spindle speeds can be changed automatically, manually, and stepless.
Vertical turret with high stiffness can change position quickly.
The length fixation device is equipped.
Optional automatic transferring line, fully automatic pipe machining can be realized.
