Laser Ablation (DAC)

TEK4’s optional DAC (Drill After Coating) technology uses a high-frequency fibre Laser to remove non-conductive coatings. This technology is confined within the FHD EDM machines to offer a solution to drill after coating.  


The big advantage of having the EDM head and the Laser head in the same machine is a perfect geometrical correlation between the 2 processes. Reducing lead times by not having to transfer the parts between two machines and reduced inventory since there is no need to have parts at two different machines.


This technology process can be used on shaped diffusor holes as well as straight holes.
