Extruded aluminum profile cross support frame for laser cutting machine

An extruded aluminum profile cross support frame for a laser cutting machine, the cross support frame comprising a connection base assembly (1), a main body (3), and T-slot bolts (6). The connection base assembly (1) is fixedly connected to the main body (3) by means of the T-slot bolts (6). An upper end of the main body (3) is provided with a first guide rail mounting surface (2). A gear rack surface (4) is provided at a corner of the upper end of the main body (3). A second guide rail mounting surface (5) is provided at a lower end of a side of the main body (3). An internally threaded cylindrical pin (7) is provided at a lower end of the main body (3). The cross support frame for a laser cutting machine of the present invention is formed by extruding a 6000 series aircraft aluminum material, and has superior strength and excellent mechanical performance, and the cross section thereof is an efficient combination of planes, straight rib plates, thin-walled cylinders, etc., thus providing a high load bearing capability, low internal stress within the extruded aluminum, low distortion after long use, high precision, light weight, and superior dynamic response to facilitate high-speed, highly responsive, and high-performance laser cutting.
