CNC Automatic Pipe Threading Machine-Huidi Electromechanical Technology

CNC Automatic Pipe Threading Machine

Main Features

1. This CNC machine is specifically designed and built for automatic threading applications while all the CNC lathe operations can still be performed.

2. With its big 62mm spindle bore diameter, the machine can process threading in different range of workpiece diameters from ½” (~12.7mm) to over 2” (~51mm).

3. The machine is suitable for continuous production when integrated with a suitable bar feeder (photo attached for reference).

4. The Spindle adopts high speed and high rigidity through dynamic balance processing.

5. It possesses rotatable control box, simple, flexible, and convenient operation with fully protected operation area.
