Modern ultra-short-pulse (USP) laser are enablers for the miniaturization of products or components in several sectors
- Automotive, Aerospace, Textiles, Medical technology, Precision engineering etc.
In these markets typical applications for the lasers include:
- Drilling, Ablation, Structuring, Cutting
The market requires:
- Efficient, precise and flexible micro machining technologies.
Hole drilling in particular has become an important application in these industries. But drilling straight walls with high aspect ratios isn't feasible if the laser beam impacts specimens at a normal incidence angle. The beam caustic affects hole corners and limits the maximum aspect ratio – that’s why new solutions are needed. A novel 5-axis technology allows beam inclination and enables straight walls, as well as negatively tapered holes. SCANLAB has introduced an innovative precession subsystem to the market that uses a novel 5-axis technology to incline the beam. These five axes (x,y,z,α, β) maximize flexibility for process development beyond typical percussion drilling: e.g. spiral drilling, trepanning and precession drilling, which means the laser is tilted and moved helically.
The five galvanometer axes allow flexible positioning possibilities, such as 3D-positioning of the focal spot onto workpieces with precise tracking of angles of incidence (AOI). For easy processing, factory calibration allows description of laser motion directly in metric units within precSYS's Cartesian image field coordinate system, which enhances ease of use and repeatability.
