Abstract
This article analyzes the workings of the CNC pipe cutting machine, further introduces how our servo system can be used on the CNC pipe cutter, and also gives several key parameter settings of the servo.
Applications
CNC pipe cutters are widely used in high-precision cutting of borehole casing, welded pipes, piping for high-pressure boilers, line pipes, and bare tubes in petroleum, metallurgical, and bearing industries.
