When laser drilling hard, brittle materials such as high-performance ceramics, taper has long been considered unavoidable. Especially with thicker ceramics, this so-called taper led to limitations in quality and functionality.
In our latest technical article, “Mittels Trepanierbohren den Taper elemininieren,”[only in German] published in Mikroproduktion, Issue 01-02/2026, we demonstrate that USP (ultra-short pulse) laser systems with optimized trepan optics now enable the achievement of precise, cylindrical bores.
