Overview
QK1327B CNC drill pipe thread repair lathe has an inclined structure. The front end of the machine tool spindle uses electric and manual chucks, and the rear end uses domestic pneumatic chucks. The main shaft bearings are ZWZ, HRB, NSK and other well-known domestic and imported brands. The upper tool rest is a domestic four-station electric tool rest, the lower tool rest is a fixed tool rest, the spindle motor is an explosion-proof asynchronous motor or the main servo motor, the CNC system is a FANUC CNC system and an automatic tool setting system, and a fixed length is set at the front end Material blocking device, optional automatic chip removal machine.
This machine tool is a high-efficiency special CNC equipment for repairing oil drill pipe threads. It can also be used as a general CNC pipe thread machine tool and also a general CNC lathe. Arbitrary tapered, spherical, curved, and chopped. Large application range, high efficiency, good accuracy and stability, good part size uniformity, easy to operate.
