Overview
QK2178T CNC pipe thread lathe has a tilting structure. The machine tool spindle adopts domestic pneumatic chucks at both ends. The spindle bearings are ZWZ, HRB, NSK and other domestic well-known brands and imported brands. The upper tool holder is a domestic eight-station electric knife. The lower tool holder is a fixed and fine-adjustable fixed tool holder. The spindle motor adopts explosion-proof asynchronous motor or main servo motor. The numerical control system is FANUC numerical control system, which is driven by three axes. The front end is equipped with a centering and tensioning device, with automatic chip removal. machine.
This machine tool is a high-efficiency special numerical control equipment 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. Cone, sphere, curved surface and cuts. Large application range, high efficiency, good accuracy and stability, good part size uniformity, easy to operate.
