The research materials of a new process of combined electroerosive-laser processing of small-diameter holes in the details of ceramic-coated gas turbine engines are presented. A mechanism is revealed that ensures high productivity and quality of processing small-diameter holes in the details of gas turbine engines made of heat-resistant alloys based on the application of combined high-speed laser-electroerosive processing using a hollow rotating electrode-tool and internal pumping of the working medium.
Keywords: electroerosive processing, laser processing, small diameter holes, hollow rotating electrode, pumping pressure, electrode rotation speed.
