た。Next, I will explain the operation. The laser beam (2) generated by the laser oscillator (1) is reflected by the t2 mirror (3),
The light is focused onto the workpiece (5) by the condenser lens (4) and melts the workpiece (5). By moving this sharpened workpiece (5) (or processing head), the workpiece (5) can be processed into a predetermined shape. However, during processing, steam or spatter from the molten workpiece (5) may enter the interior through the processing nozzles (6), (7) and adhere to the condenser lens (9). For this reason, the laser beam (2) is absorbed by the condensing lens (9), making it necessary to replace the condensing lens (9). However, to replace the condenser lens (9), first remove the processing nozzles (6) and (7) below the spacer (8), then remove the fixing screws (tn), and then replace the condenser lens (9). I had to replace it with a new condensing lens and reassemble it.
