Overview
The CNC340C CNC pipe thread coupling lathe has a monolithic and inclined structure. The machine tool spindle chuck uses domestic hydraulic power chucks. The spindle bearings are ZWZ, HRB, NSK and other domestic famous brands and imported brands. The spindle motor is 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 an upgraded version of QK1319F CNC pipe thread coupling machine tool. The spindle bearing lubricating oil products are maintenance-free (grease lubrication). It is a stable and special CNC equipment for processing special threads for petroleum oil casing couplings. It can also be used for general CNC. The machine tool is used to process the outer circle, inner hole, end surface, arbitrary cone surface, spherical surface, curved surface, and chopped disc parts. Large application range, high efficiency, good accuracy and stability, good part size uniformity, easy to operate.
