The Rosnok QK1319 CNC pipe threading lathe machine is developed to handle demanding pipe threading work with steady accuracy and long-term structural reliability. Its enlarged spindle bore, rigid casting design, and precise servo-driven feed system allow the machine to cut clean, uniform threads on tubing and casing materials without losing stability under heavy loads. Combined with an intuitive CNC interface and smooth linear motion control, the QK1319 ensures stable, repeatable threading quality during extended production runs.
