The present invention relates to a laser cutting head, which includes: a body part which forms an outer body, and has a focus lens installed to gather a focus of a laser beam; a nozzle part (5) which is installed at a front end of the body part (3), and irradiates the laser beam (M) focused by the focus lens (11) to a cut object (M); and a clamping part (7) which is installed at the front end of the nozzle part (5) to surround a nozzle (7) of the nozzle part (5), and pressurizes the cut object (M) not to be lifted while cutting the cut object (M). Therefore, when the cut object is cut by the laser beam, the laser cutting head can pressurize the vicinity of a cutting part of the cut object widely and uniformly by the clamping part directly or indirectly. Thus, the laser cutting head can prevent lifting at the cutting part, especially at the cutting part at an edge of the cut object, and thus, can improve processing precision or quality at the cutting part at the edge further. |
