<p>PROBLEM TO BE SOLVED: To provide a laser beam processing method for nodal rings which constitutes a curving pipe of an endoscope capable of decreasing the number of processing stages and the number of jigs meeting the diameter of a pipe to be processed and having excellent workability to allow the easy and exact processing of connecting parts and bulging. SOLUTION: This method consists of a primary laser beam processing stage for terminating the end face of a long-sized pipe and cutting the member to be worked of a required length, a stage for ejecting the member 11 to be worked which is cut and processed in the primary laser beam processing stage from a laser beam processing section 19 via an unloading section 20 and a stage for recovering the member 11 to be worked.</p> |
