Device and method for producing drill holes in an edge of a turbine blade

摘要

The device has a guide (1) provided for a drilling device and comprising a bearing element (2), where a gap is formed in the bearing element. The gap is limited by bearing surfaces and has a contour corresponding to a shape of a turbine blade edge to be machined. Two guide modules (3, 4) lie opposite to each another, and are attached with a side surface of a turbine blade. The guide modules form a tension device for fixing the guide on the turbine blade. The gap in the bearing element is delimited by bearing prisms. The drilling device has a rotating electrode formed as a drilling tool. An independent claim is also included for a method for producing bores in an edge of a turbine blade.
