Overview
QK1312G CNC pipe thread lathe has an inclined structure. The front and back ends of the machine tool spindle use domestic pneumatic chucks. The spindle bearings are domestic famous brands and imported brands such as ZWZ, HRB, and NSK. Frame, the spindle motor adopts explosion-proof asynchronous motor or main servo motor, the numerical control system is FANUC numerical control system, and automatic chip removal machine can be optional.
This machine tool is a special numerical control equipment for processing petroleum oil pipe threads and special special threads for petroleum oil pipes. It can also be used as a general numerical control machine tool. It can perform external circles, internal holes, end faces, arbitrary cones, spherical surfaces, shafts and disc parts. Processing of curved surfaces and cuts. Large application range, high efficiency, good accuracy and stability, good part size uniformity, easy to operate.
