As part of a collaborative project involving a new, state of the art trepanning head, ALPhANOV has demonstrated the potential of femtosecond laser for deep drilling of holes with a high aspect ratio.

Stainless steel, Φ60 µm x 900 µm, conicity 0°

Such quality, including the potential for reverse taper holes, is important for future applications, for example injection nozzles drilling for the latest generation of fuel injectors.
