PURPOSE:To improve processing accuracy and to reduce an initial cost by providing a floating member the surface on the work side of which can move freely to a profiling guider and connecting the supporting member thereof to a distance detector. CONSTITUTION:The annular floating member 11 is provided via the supporting member 15 to the profiling guider 10 and the member 11 is freely turnably supported by means of a pin 13 in an intermediate ring 12. The intermediate ring 12 is supported in a supporting part 15 by a pin 14 orthogonal with the pin 13 on the diameter. The arm part 15b of the supporting member 15 is movably connected to the distance detector fixed to a processing head 1. The floating member 11 in the above-mentioned mechanism is floated from the surface 6a of the work 6 by the flow of a processing gas 7. The floating member 11 is maintained parallel even in the case of the inclined surface 6a. The laser beam processing accuracy is, therefore, improved and the reduction of the initial cost is resulted from the simplification of the control unit. |
