<p>PROBLEM TO BE SOLVED: To secure the detection accuracy and time of a device which fixes a cutting position based on a change in the transmission of radial rays with respect to a compressor 90 for cutting a casing at a position corresponding to the end part of a stator, even when weak radial rays are used. SOLUTION: A dismantling device 1 is provided with a cutter 31 for cutting the casing, a radiation source 21 for radiating radial rays, a detector 23 for detecting the radial rays, a motor for moving a chuck, and a control computer. The detector 23 detects the radial rays through a slit-like detection hole. The motor for moving a chuck moves a compressor 90 so that the compressor 90 passes through between the radiation source 21 and the detector 23. The control computer fixes the cutting position based on the radiation transmission of each part of the compressor 90 obtained from the detector 23, and makes the cutter 31 cut the casing.</p> |
