Helical Drilling Optic

key component for the production of
high precision holes
The D+G Helical Drilling Optic allowes the fabrication of microholes of highest precision.
Increasingly small holes with extraordinarily restrictive tolerances, which are expected
particularly in the field of fuel injection technology, can be obtained. The desired diameters
of the holes typically reach down to 50 µm at a material thickness up to 1 mm, resulting in
aspect ratios of up to 20. Special hole geometries with defined tapering such as a negative
conicity are frequently demanded for specific flow formation. Such. The drilling process
itself has high reproducibility, as well as high reliability and the drilling system is easy to
handle. Key features:
•
•
•
•
•

high precision and stability in 24/7 production
short installation time
no influence on laser parameters (beam quality, pulse duration, polarization)
complete integration possible
easy and fast exchange of wedge set
