Laser cutting machines have existed as early as… It first emerged in the 1970s; after more than 30 years of exploration and development in the global sheet metal processing equipment manufacturing industry, it has been widely applied in fields such as automobile manufacturing, construction machinery, aerospace, and mold development. However, to date, internationally… Laser cutting machine Its R&D relies primarily on developed manufacturing countries abroad.
China’s laser cutting technology still lags far behind advanced technologies abroad. At present, the country possesses… Laser cutting machine Most of these are imported at high prices from overseas, and there is still a certain gap in theoretical research, which is primarily focused on realizing the spatial trajectories of parts and the part‑cutting process. During laser cutting, the laser… The interaction between the material and the curved surface—the underlying laser cutting mechanism—has yet to be thoroughly investigated; however, as early as the 1970s, researchers abroad began proposing corresponding models. Today, most machining equipment employs either a robotic arm configuration or a five-axis simultaneous‑control cutting approach. The technical principles behind these machining approaches are identical to those of conventional five‑axis CNC machining—except that the focused laser beam is treated as a specialized “laser tool,” with the trajectory of the laser focus serving as the envelope of the machining path. To process spatial curve geometries on complex curved surfaces, it is generally necessary to develop intricate multi‑axis interpolation CNC programs and perform interference checks. The drawbacks of this method include high equipment costs, poor overall machining accuracy due to an excessive number of linked axes, and significant technical challenges in equipment operation and maintenance.
New type Laser cutting machine Including the workbench, with components installed on the workbench and moving along… The left–right slider that moves along the X‑axis, the front–back slider that is movably mounted on the worktable and travels along the Y‑axis, the up–down slider mounted on the left–right slider and capable of moving along the Z‑axis, the cutting head mounted on the up–down slider, and the rotary axis mounted on the front–back slider. The rotary axis can rotate 360 degrees; a laser channel is provided on the up–down slider; the laser generator transmits laser beams to the cutting head via the laser channel; and the rotary axis is equipped with a clamping assembly for securing the workpiece. Since the left–right slider can move horizontally across the worktable, the front–back slider can move horizontally along the length of the worktable, the up–down slider can move vertically, and the rotary axis can rotate, the laser cutting machine can complete the laser processing of a workpiece simply by coordinating the left–right slider, the front–back slider, the up–down slider, and the rotary axis. To facilitate quick and convenient attachment of the workpiece to the rotary axis, the clamping assembly includes a base plate fixed to the rotary axis, positioning pins, and locking components mounted on the base plate. To simplify the overall structure, the machine also features a first drive motor for operating the left–right slider, a second drive motor for driving the front–back slider, a third drive motor for operating the up–down slider, and a fourth drive motor for rotating the rotary axis. When performing straight cuts, angled cuts, and arc cuts on workpieces, the control system ensures that the distance between the cutting head and the cutting point on the workpiece remains essentially constant, and that the cutting speed remains essentially consistent throughout the process.
In addition, during arc cutting, the laser beam is perpendicular to the tangent at the cutting point, which allows… Laser cutting machine Processing The cutting accuracy of the workpiece is extremely high. At the same time, you can simply set the parameters on the control device to start cutting the workpiece—operation is incredibly convenient.
