QK SERIES CNC PIPE THREADING LATHE (OIL COUNTRY LATHE):
The oil country lathe is mainly developed for the pipe thread turning in the oilfield and is suitable for turning of various pipe threads. The lathe belongs to a universal CNC pipe threading lathe of a semi-closed-loop control system and also can be used as a common CNC lathe, and is suitable for machining complicated shapes shaft, sleeve, disk parts. Such as turning, cylindrical surface, conical surface, arc surface, face, grooving, chamfering, thread and so on.

FEATURES:
(1) The lathe body is integral casting structure.
(2) Strong rigidity headstock which can adapt to heavy processing.
(3) CNC system uses FANUC 0i Mate-TD (also according to customers' requirements match other systems)
(4) The spindle bore is 200mm, it is easy and enough for customer to feed pipes through the spindle bore, it can not only machining the surface for the bearing, but also can machining the thread or screw.
(5) We can customize the automatic feeding device according to different workpiece, the production will be competitive.
APPLICATION:
All kinds of drill pipe & drill collar, oil pipes and so on.
