Overview
QK1319G CNC pipe thread lathe is the heavier weight of QK1319D CNC pipe thread lathe. Its bed is tilted. The machine tool spindle adopts domestic pneumatic chucks at both ends. The spindle bearings are ZWZ, HRB, NSK and other well-known domestic brands and imported brands. The tool post is a two-station fixed row tool post. The spindle motor adopts an explosion-proof asynchronous motor or a main servo motor. The numerical control system is a FANUC numerical control system. An optional automatic chip removal machine is optional.
This machine tool is a special numerical control equipment used for processing petroleum oil casing threads and special threads for petroleum oil casings. It can also be used as a general numerical control machine tool. It can perform external circles, internal holes, end faces, arbitrary cones on shafts and disk-shaped parts Surface, spherical surface, curved surface, and cuts. Large application range, high efficiency, good accuracy and stability, good part size uniformity, easy to operate.
