(14" Large Spindle Bore x 1500/3000/5000 Workpiece Length)

Product Description

Features:

1. The lathe was developed mainly for the turning of oil-field pipe threads.
2. It is suitable for the turning of arious kinds of pipe threads, and is also can be used as universal CNC Lathe.
3. The machine is simple CNC lathe which use half closed-loop control system, which belong to popular CNC pipe thread lathe.
4. It can cut many complex parts as shaft, sleeve and dish, internal and external cylindrical surfaces, concal surfaces, holows, end plane, grrove, chamfer, screw thread, and so on.
5. It is suitable for repeated and medium batch manufacturing in chief.
