Overview
QK1334G CNC pipe thread lathe has a tilting structure. The front and back ends of the machine tool spindle are made of domestic pneumatic or hydraulic chucks. The spindle bearings are ZWZ, HRB, NSK and other domestic famous brands and imported brands. The tool holder is a fixed two-station row. The tool holder and the spindle motor adopt explosion-proof asynchronous motor or main servo motor. The numerical control system is FANUC numerical control system. The front end is equipped with pneumatic fixed-size blocking device and optional automatic chip removal machine.
This machine tool is a large-scale special numerical control equipment used for petroleum casing thread and special thread processing for petroleum casing. It can also be used as a general CNC lathe. Surface, spherical surface, curved surface, and cuts. Large application range, high efficiency, good accuracy and stability, good part size uniformity, easy to operate.
