These are widely used for cutting thick steel plates, which are the primary material for railway bridge girders and other heavy steel structures. CNC control ensures precise and repeatable cuts, which is crucial for the dimensional accuracy of large components. This technology allows for complex shapes to be cut with minimal waste and high speed. The use of these CNC solutions ensures that fabricated parts meet the stringent quality standards of RDSO, which includes strict tolerances on dimensions, hole pitch, and overall structural geometry. The automated nature of CNC fabrication reduces human error, increases production speed, and provides a documented, reproducible process that is critical for safety-sensitive railway applications.
