PROBLEM TO BE SOLVED: To provide a barrel feed structure of a plurality of barrels laser beam machine which is capable of improving the machining accuracy and increasing the degree of freedom in the machining. SOLUTION: A barrel feed structure of a plurality of barrels laser beam machine is basically provided with a main spindle 30 provided in the Y-axis direction astride a table 11 movable in the X-axis direction on which a work id placed, a main movable piece 40 which is movable on the spindle 30, and to which a main barrel 41 optically connected to a laser beam oscillator is fixed, and a sub movable piece which is movably supported by the main movable piece 40 in the Y-axis direction, and supports at least one sub barrel optically connected to the laser beam oscillator, a bar-shaped stator with straight- arranged magnets built therein are provided on the main movable piece 40 in the Y-axis direction, the sub movable piece with a soil built therein is supported on the stator to form a linear motor by the stator and the sub movable piece, and the sub barrel fixed to the sub movable piece is moved in the Y-axis direction with respect to the main barrel. |
