CNC (Computer Numerical Control) positioners offer a higher level of automation and precision. They are primarily used for welding circumferential seams, tilting and rotating the workpiece so the weld seam is always in the optimal position. Equipped with servo motors and high-precision reducers, they provide high rotational accuracy and precise positioning. These systems are often designed for integration with automatic welding machines, enabling fully automated welding processes. Some models also feature a central through-hole in the worktable, allowing long workpieces to pass through, which is convenient for pipe welding
