- The quality requirements on aperture size and slit width in precision drilling and cutting have increased immensely due to the technology trend of minuaturization. In this context, high-precision helical drilling optics (HDO) has been invented and offers hightest machining technology for metal and non-metal materials if used with ultra-short laser radiation. In addition, HDO offers the flexibility and process stability of controlled micro-aperture taper for the preparation of vertical or positive and negative tapered micro-apertures and for controlling the tilt and width of the cut in the cutting processes.
- Since the first introduction to the global market in 2008, the helical drilling technology has undergone several optical and system developments to make it suitable for current and upcoming higher processing requirements. Today‘s seventh generation HDO v7 can be used in three different wavelength ranges: UV, green and IR. In addition, the HDO v7 successfully uses a modular design, separating the core rotary module and the processing observation module, and standardizing the interface to enable full integration into different processing systems. The HDO v7 is becoming a key enabler for wide range of applications for micro-holes in high-end products such as turbine blades & functional surfaces.
