The invention discloses a light-duty gantry
numerical control cutting machine which comprises a support, a transverse guide rail, a longitudinal guide rail, a main controller, a
cutting head and a longitudinal transmission device, wherein the transverse guide rail and the longitudinal guide rail are perpendicular to each other, and the
cutting head and the longitudinal transmission device are electrically connected with the main controller; the longitudinal guide rail comprises a driving-side double-tracked support bracket and a driven-side single rim support bracket which are relatively independent; and one end of the transverse guide rail is connected with the driving-side double-tracked support bracket by the longitudinal transmission device and a slider, and the other end of the transverse guide rail is arranged on the driven-side single rim support bracket by a support roller. Due to the double-tracked design and split structure as well as adjustable leg supporting of the longitudinal guide rail, the installation process of the cutting
machine is simplified, the assembling, disassembling and debugging of the cutting
machine are facilitated, and the application quality of the cutting machine is ensured; meanwhile, the cutting machine is high in
machining accuracy and reliable in performance; and in addition, because the adopted aluminum support bracket is light in weight, the cutting machine is convenient to carry and flexible in transportation, therefore, the cutting machine can be widely applied to the
processing and production of various cutting products.
