This H-beam cutting machine is widely used for cutting and processing structural pipeline components in construction, chemical, shipbuilding, mechanical, metallurgical, power generation, and other industries. Traditionally, most of this type of processing relied on outdated and labor-intensive methods such as prototyping, manual drawing, lofting, hand cutting, and hand polishing. The CNC line-cutting machine can efficiently cut and process such workpieces with minimal effort. Operators do not need to calculate or program manually. They simply input the pipe radius, intersection angle, and other system parameters for crossing pipes, and the machine automatically cuts the intersection line of the pipes, including intersecting holes and weld grooves. The CNC pipe line-cutting machine uses digital control and is available in models with 2 to 6 control axes, among others. Each model allows overlapping of control axes during cutting and includes functions for cutting intersecting lines and intersecting holes, fixed-angle cutting, fixed-point beveling, variable-angle cutting, and pipe cutting compensation.
