[0002] Gantry CNC Cutting Machines: These cutting machines feature a gantry-style structure with a variety of horizontal spans, including 3m, 4m, 5m, 6m, and 8m. They utilize dual-side drives, ensuring stable operation, optimal configuration, and high efficiency. They are suitable for cutting large, medium, and small steel plates from various metal materials, including carbon steel, manganese steel, and stainless steel. They can also be configured with multiple cutting torches or configured for both special-shaped and straight-strip cutting, depending on user requirements. Capacitor or plasma automatic height adjustment systems are also available.

[0003] A cutting machine disclosed (publication number: CN203579814U) includes an operating table, characterized by a 90° baffle on one side, a scale gauge on the baffle, a cutting machine body located in the middle of the baffle, a material holding rack in front of the cutting machine body, and a roller for conveying the cut material in the middle of the operating table. This cutting machine is simple to operate, safe, and efficient, and can fix the height and width of the cut material and easily adjust its length.
