General purpose

In aircraft engine, cooling holes are widely used for creating a film of cooling air on the surface of turbine blades and vanes to prevent them from melting, hole drilling EDM with five axes is a robust and consistent solution in terms of recast layer and productivity.
In cutting tools, the internal cooling can reduces the high cutting temperature generated and increase cutting tool life, optimum chip removal and increase cutting process reliability, these internal cooling holes can be done by hole drilling EDM with five axes in a single setup.
