CSM MACHINERY’s automatic, numerically controlled (NC) tube cutting line represents a state-of-the-art solution for maximizing efficiency and production. Thanks to its numerical control (NC), the machine can manage different cuts on the same tube, offering unparalleled production flexibility. The innovative dual-unloading system automatically separates cut lengths, simplifying downstream logistics.
The cutting line’s advancement is managed by a pusher on a controlled axis, which ensures millimeter-level precision. Furthermore, through sophisticated nesting settings, the machine optimizes material utilization, drastically reducing scrap.

AUTOMATIC LOADING TABLE
for tube bars, adjustable height to feed tubes of different diameters.
TUBE CLAMPING SYSTEM DURING HANDLING
which also allows for the removal of scrap (last piece that cannot be cut).
CUTTING UNIT
UNLOADING DEVICE
with two-position selection flap for the cut tube.
NUMERICAL CONTROL PUSHER
to feed the loaded tube into the cutting unit and manage different lengths from the same bar.

CONTROL PANEL
to configure cutting operations (the panel is shared with the cutting unit and the discharge device).
The score and pull-apart system is designed to overcome the problems presented with orbital cutting of a similar conception but realized using engraving wheels. In particular, this system allows the tube to be cut without deformations on the cut edge. The tube is not cut by blades that insist orthogonally on the wall of the tube, but by the combined action of a scoring tooth (made with a three-edged tool), which progressively removes material along a circular section of the cylindrical wall, thinning it, and a clamp that detaches the tube segment.
The saw cutting system incorporates a high-resistance circular blade that rotates at high speed to perform rapid and clean cuts. This technology offers the capabilities to manage different types of tube thickness, as well as different materials, with the precision of ninety-degree cuts. Furthermore, thanks to the robust materials and the cutting technique, the tool’s lifespan is extended, ensuring sustained durability and reliability.
Guillotine cutting lines are designed for producing custom-sized tubes with the internal diameter calibrated at both ends and customized lengths. This type of system is primarily selected for medium to large-scale production, ensuring rapid cutting diameter changeovers. The subsequent punching operation, used to eliminate the “heart-shaped” distortion caused by the cut, can be performed manually via a punching gun or automatically with a punching transfer system downstream of the tube cutting.
