Engineered by our ARGES brand, the Precession Elephant 2 is the perfect solution for precession applications. The heads are designed for high-precision laser drilling, cutting and micromachining applications and are used 24/7 in production facilities around the world.
This scan head offers maximum flexibility for the drilling of innovative borehole-and edge geometries of differing conicity, taper angles and shapes, and allow the production of perfectly round, elliptical and custom-shaped micro holes. The Precession Elephant 2 is available for ultraviolet, green and two infrared wavelength ranges, each with two different focal lengths.
All ARGES scan heads are compatible with ARGES ASC controllers and InScript® software.
Designed for high-precision drilling of customized borehole shapes and taper angles with the highest reproducibility. Also ideal for advanced cutting applications with precise edge angle control.
Typical process parameters include:
Our precession scan heads allow not only the positioning of a laser beam, but also the setting of the incidence angle of the beam at each point of the workpiece,. For a drilling process, the incidence angle is also called the precession angle. When drilling a borehole with high precision, the inclination of the internal hole surface, the so-called taper angle, can only be produced in a reliable and reproducible way if a precession scan head is used. The production of defined edge angles in laser cutting or laser micromachining also requires the use of precession heads.
Process gases such as nitrogen or helium are frequently used in laser material processing to ensure the best possible results. When using process gases, it is important not only to select a suitable protective gas, but to also consider the flow dynamics aspects, which can significantly affect the processing quality and processing time. The drilling nozzle of the Precession Elephant 2 has been designed to precisely guide the process gas and, together with the system design and configuration, is an important contributor to ensuring optimum results in laser micro-processing.
The protective gas flows through a channel in the drilling nozzle directly onto the workpiece. Due to the compression of the protective gas, the nozzle exit pressure is significantly higher than the ambient pressure. This under expanded flow behavior is evident by the formation of a compression structure that is similar in shape to polished diamonds and leads to the creation of so-called Mach discs.
The process gas density is higher within a Mach disc, which results in an improved ablation process in laser material processing.
