Scanlab precSYS micromachining sub system

5-axis micro processing

The precSYS micromachining sub system enables ultra-short

pulsed 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 com

bines 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, innova

tive 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.

system operation thanks to factory default settings and calibra

tion as well as automatic fine-adjustment.

Principle of Operation

precSYS lets you 3D-position the focalspot onto workpieces with

precise tracking of angles of incidence (AOI). You can simultaneously

vary progression of focal motion, angles of incidence and laser intensities

etc. High-end scan technology with small mirror rotation angles and

low moving masses ensure highly dynamic processing with trepanning

or precession frequencies up to 650 Hz (39 000 rpm). The system

works without any rotary optics.

Advanced digital encoders, control algorithms and application-optimized

servo control enable contour-true, speed independent processing with

maximum precision. The system is servo-regulated for stable positioning

at precession frequencies up to 650 Hz. Specially conceived for USP

precision processing, the opticalpath is polarization-maintaining and

accommodates pulse energies up to 300 µJ at 1030 nm and 65 µJ at

515 nm.

System Design

Active water cooling of beam-guidance components (including galvo axes)

and of spatially separated electronics makes the system robust against

load-dependent temperature fluctuations. Moreover, the system's innovative

beam guidance provides suitability for up to 50 W lasers.

A sealed, gas-purged optical beam path(overpressure) guarantees optimum

cleanliness even in harsh industrial conditions – thereby enhancing system

service life and processing accuracy.

Automatic Fine Adjustment

precSYS‘s factory-precalibrated beamposition measurement unit can be used

for monitoring the system’s beam position. If the beam position exceeds the

application specific tolerance limit, then the software can be used to readjust

the beam back to its original zero position by the system internal five galvo axes.

Advantages:

•  Beam position stabilization close to the working field minimizes deviations

along the beam path from laser to workpiece

•  Lastingly reproducible process results without complicated effect analysis

and manual readjustment

•  Beam position monitoring via maintenance software program

•  Automatic readjustment of beam position and angle via the DrillControl

software  (regulation via system-internal galvo axes)

•  Supports precSYS alignment during commissioning and servicing
