A laser beam machining center comprises a control system (1), a laser (2), an optical path system (3), a machine tool (4), an optical condenser system (5), a laser cutting head (6), a gas source (7), and a waste collection device (8). The laser cutting head (6) is movably mounted on the machine tool (4). The optical path system are connected to and located between the laser (2) and the laser cutting head (6). The laser cutting head (6) is provided therein with a protective gas nozzle (9) in communication with the gas source (7). The optical condenser system (5) is located between the optical path system (3) and the laser cutting head (6). The waste collection device (8) is located below the laser cutting head (6), and the laser (2) and the machine tool (4) are both communicatively connected to the control system (1). The laser beam machining center has a high working efficiency and superior machining precision, and is energy saving and environmentally friendly.
