Abstract
A processing device for film cooling holes on blade of aviation engine includes a working box. A workpiece clamping mechanism is arranged in the working box for holding the workpiece. A cover body having an internal space communicated with an internal space of the working box is connected to an upper part of the working box. A laser processing mechanism is connected to a top end of the cover body and can produce laser rays to carry out laser processing on the workpiece. The cover body is connected to a liquid supply mechanism and an acid gas filtration mechanism. The liquid supply mechanism can spray an acidic solution to the workpiece in the working box, and the working box can collect the acidic solution. The acid gas filtration mechanism can filter acid steam produced during processing. A working method of the processing device is also provided.
