PURPOSE: To reduce manufacturing costs by quickening the speed for working a refrigerating compartment. CONSTITUTION: In a working system 1 for working a workpiece such as a refrigerating compartment 20, a displaceable laser beam focalizing head 11 for irradiating a laser beam onto the refrigerating compartment 20 to be worked, a laser source 3 for supplying the laser beam to the laser beam focalizing head 11 and a controller for electronic digital controlling the displacement of the laser beam focalizing head 11 are provided in an optional setting position within the working area for the refrigerating compartment 20. |
