CNC Pipe Threading Lathe
QKD1335×3000
This series CNC pipe threading lathe is designed with full servo headstock structure and applies combined electric chuck, it is high-efficiency equipment in processing and repairing drilling pipe, drilling rod, thread coupling in oil field. Meanwhile, it has all the common functions of normal CNC lathe such as processing the inner bore and end face of shafts and disks, it can be widely used in industries including petroleum exploiting, minerals mining, chemical piping and geological prospecting etc.
Feature
- One-piece bed adopts high strength iron to ensure rigidity and precision.
- Ultrasonic frequency quenched guide-ways ensure good wear-resistance.
- Carriage and guide-way contact surface use Turcite B to maintain accuracy.
- Big spindle bore and double chucks to ensure processing big diameter pipe.
- 4-jaw electrical chucks ensure high efficiency in improving batch processing.
