Description

Technical Field

[0001] The utility model belongs to the field of laser cutting machines, and particularly relates to a high-strength crossbeam. Background Art

[0002] A laser cutting machine is a machine tool that utilizes the principles of laser cutting. It typically consists of a bed, a workbench mounted on the bed, a crossbeam mounted on the bed, and a cutting head mounted on the crossbeam. The bed is equipped with guide rails and a rack, while the crossbeam is equipped with gears and a motor. The gears on the crossbeam mesh with the racks on the bed and, driven by the motor, rotate to drive the crossbeam, which then slides on the guide rails. To operate, the material to be processed is first secured to the workbench, and then the crossbeam is controlled to slide relative to the workbench, driving the cutting head to cut the material.
