5-axis micro processing The precSYS micromachining sub system enables ultra-shortpulsed laser micro processing of flexibly variable geometries, e.g. fabrication of positively/negatively conical or ideal cylindrical, round or elliptical drill holes with high aspect ratios. The precSYS combines leading-edge high-end scan technology, integrated control, embedded PC and user-friendly software. This enables laser micro processing with ultimate dynamic performance and precision. Its graphical user interface facilitates straightforward creation and testing of micro-processing jobs. precSYS's robust, innovative construction ensures maximum dependability in industrial applications. Its compact, modular design and specially adapted hardware and software interfaces allow easy, optimal integration into customer-specific laser machines and networked production environments (industry 4.0). precSYS offers observation ports for process-monitoring and beam-monitoring add-ons. SCANLAB ensures time-efficient system alignment thanks to factory default settings and calibration, as well as an optional automatic fine-adjustment package. Key advantages: • User-friendly creation of micro-processing operations with 3D visualization • Flexible USP processing with variable angle of incidence • Maximum dependability and stability for highest precision • Speed-independent contour fidelity thanks to innovative control algorithms • Industrial suitability and modular design • Highly integrated solution with embedded PC • Ultra-precise pre-calibration and alignment software • Optional automatic fine adjustment • Comprehensive on-site customer service Typical applications: Typical industries: Drilling Ablation Structuring Cutting Automotive Aerospace Textiles Medical

Principle of Operation precSYS lets you 3D-position the focal spot onto workpieces with precise tracking of angles of incidence (AOI). You can vary progression of focal motion, angles of incidence and laser intensities etc. System Overview (standard version with no options) Legend 1 Gas-purged 5-axis scan unit (x, y, z, incidence angles a, b) with purge gas monitoring 2 Control electronics and embedded PC 3 Ethernet and industrial connector (connections for power, PLC, laser and remote access) and status LEDs 4 Water cooling for thermal stability (galvo axes and electronics separately...

5-Axis Laser Focus Positioning Possibilities process gas nozzle angular orientation laser focus z y x 3D positioning Flexible Processing Due to precSYS's possibility to position the laser beam in 5 axis (x, y, z, a, b), it offers highest flexibility for process development beyond typical percussion drilling, spiral drilling and trepanning. The process is called precession drilling when the laser is helically moved with tilted laser beam. The precSYS's high precession frequencies even enable production of deep bore holes with high aspect ratios and vertical walls at one-second intervals (for...

DrillControl software System integration and control System control ( PLC) Ethernet network (optionally with DHCP server) Ethernet interface DrillControl software Power/PLC/Laser interface Embedded PC and RTC5 control boards An intuitive graphical user interface (GUI) with 3D job visualization helps you easily create and simulate processing jobs. Control and remote communication is via TCP/IP over Ethernet. Factory calibration enables description of laser motion directly in metric units within precSYS's cartesian image field coordinate system. Job designer Laser and other system components...

100-µm bore holes in steel (entrance side) Processing results compared to a human hair The precSYS has been developed to machine fine hole diameters in the submillimeter range with high aspect ratios and quick process times, using ultra short pulsed laser beams. Single bore hole from figure 1 magnified This enables creation of positively and negatively conical or cylindrical bore trajectories. precSYS lets you execute not only 3D geometries, but also 2D marking. In addition to circular or elliptical markings, you can also easily mark text with various fonts and font sizes (see figure 10)....

Flexible geometries in 300-µm-thick steel The high quality, dependability and industrial suitability of SCANLAB's scan solutions are the result of long-standing experience in developing and manufacturing galvanometer scanners and scan systems. SCANLAB scan heads have been deployed by industry in large quantities for many years. Each individual scan head earns approval for customer delivery only after first passing the SCANcheck endurance test.
