Overview
QK1309A CNC pipe threaded coupling lathe has a tilting structure. The machine tool spindle chuck uses domestic hydraulic power chucks. The spindle bearings are ZWZ, HRB, NSK and other domestic famous brands and imported brands. The tool holder is fixed at two stations. The tool holder, the spindle motor adopts explosion-proof asynchronous motor or main servo motor, the numerical control system is FANUC numerical control system, and the automatic chip removal machine can be optional.
This machine tool is a special numerical control equipment used for processing petroleum oil casing coupling threads and special threads for petroleum oil casing couplings. It can also be used as a general numerical control machine tool. Processing of end face, arbitrary conical surface, spherical surface, curved surface and cuts. Large application range, high efficiency, good accuracy and stability, good part size uniformity, easy to operate.
