Pipe threading lathe is also known as big bore lathe machine, large bore lathe, oil country lathe, double chuck lathe, oil field lathe and hollow spindle lathe.
Our pipe threading lathes can handle pipe diameters from 30 mm to 270 mm/1 3/16″ to 10 5/8″
The lathe is offering exceptional versatility for machining a wide range of thread types, can accurately process API 5B, metric, imperial and tapered threads, support module design and DP parameter adaptation, and has general CNC lathe functions like turning, boring, facing, grooving, and drilling for shafts, disks, and pipe ends. It enables stable, efficient and high-precision mass production of complex pipe thread connection systems meeting strict international standards. The double-chuck lathe ensures stable threading turning for long workpieces of 6 m, 8 m, 12 m, and 16 m in length. It can be equipped with pneumatic or hydraulic double chucks to achieve automated clamping. Additionally, an optional automatic unloading device is available. One loading/unloading device can be paired with two CNC pipe threading lathes to achieve even higher machining efficiency.
It is widely used in high-end fields such as oil and gas drilling and production, and high-pressure pipelines.

This series is used for CNC turning and threading of oil pipes, casing pipes, drill pipes, and pipe-type workpieces with moderate diameter requirements.
Models may include QK1213, QK1219, QK1222, QK1225, and QK1227, depending on pipe diameter, spindle bore, and guideway configuration.
The spindle bore should be selected according to the maximum outside diameter of the pipe that needs to pass through the spindle, plus clamping and machining allowance.
Yes. Thread processing depends on CNC system, tooling, pipe size, and thread standard. Please send the thread type and pipe drawing for confirmation.
