Heun is able to drill around the corner. A special process enables us to work the piece at points difficult to access, with bended and rotating electrodes.
In the manufacture of turbine blades, coolant holes are required in extremely steep entry and exit angles. Even though the material thickness is not known, the breakthrough of the drilling without damage of the close rear panel has to be guaranteed.
Rationalization / automation in a network together with EROWA, Hirschmann, 3R, AGIE, Roeders, Makino, Zimmer + Kreim, Zwicker has been realized.
With a special machine from Heun the sensational drilling depth of 2,600 mm has been reached with an electrode diameter of 3 mm.
The challenge is not to drill holes, but to carry out geometries and surface abrasion. Special cooling channel structures are required for turbine blades. On the same machine as it is on a machine.
