Overview
QK1328 CNC pipe thread lathe has a tilting structure. The front and rear ends of the machine tool spindle use domestic pneumatic chucks. The spindle bearings are ZWZ, HRB, NSK and other domestic well-known brands and imported brands. The tool holder is a fixed two-station row tool holder. The spindle motor adopts explosion-proof asynchronous motor or main servo motor. The numerical control system is FANUC numerical control system and automatic tool setting system. The front end is equipped with a fixed-size blocking device and an optional automatic chip removal machine is optional.
This machine tool is a 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 CNC lathe. It can perform external circle, inner hole, end face, arbitrary Cone, sphere, curved surface and cuts. Large application range, high efficiency, good accuracy and stability, good part size uniformity, easy to operate.
