High-End Laser Processing

The schematic diagram depicts XL SCAN’ssystem configuration.

This scan solution combines SCANLAB’s proven scan head

control with an XY stage positioned via ACS’s innovative motion

control system.

The laser spot’s movement across the workpiece is automatically

split between the scan head and XY stage, thus assuring optimal

utilization of the entire system’s available dynamics. The scan head

is responsible for short rapid motions, while the stage extends the

working surface.

Unbeatable precision meets large-field laser processing

XL SCAN is a combined scan solution jointly-developed by  SCANLAB

and ACS Motion Control. This innovative solution enables maximum-

precision processing of workpieces without size limitations.

Key Features

• Scan solution for large-field processing

• High throughput

• Market-leading accuracy

• No stitching errors

• High-dynamics processing without stage vibration

• Unlimited job duration

• Automatic laser control, e.g. Spot Distance Control (SDC)

• Capability of combining multiple software instances, stages

and scan heads

XL SCAN is based on the innovative concept of the SCANmotion

Control software, which combines the synchronous control of

a scan head and an XY-table with intelligent trajectory planning.

XL SCAN thus  delivers the highest precision of all solutions

currently on the market. Maximum flexibility and enormous

throughput increases are  attainable by combining XL SCAN

with several  SCANmotionControl instances, multiple stages

or multi-head systems.

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

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.

Key advantages:

•  User-friendly creation of micro-processing operations with 3D

visualization

•  Flexible USP processing with defined variable angle of incidence

•  Maximum dependability and stability for highest precision

•  515 nm variant for even more precise laser processing

•  Speed-independent contour fidelity thanks to innovative

control algorithms

•  Designed for usage in industrial serial production

•  Ethernet and EtherCAT control interfaces

•  Highly integrated solution with embedded PC

•  Ultra-precise pre-calibration and alignment software

•  Automatic fine adjustment (system monitoring)

•  Comprehensive on-site customer service

Typical applications:

•  Drilling

•  Ablation

•  Structuring

•  Cutting

Typical industries:

•  Automotive

•  Electronics

•  Textiles

•  Medical technology

•  Precision engineering

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.

SCANLAB ensures time-efficient system alignment and precise

system operation thanks to factory default settings and calibra

tion as well as automatic fine-adjustment.

high power meets high dynamics

The welDYNA scan head enables innovative high power applica

tions by a unique set of properties:

• Suitable for multi-kW lasers

• Designed for highest beam quality (single mode)

• High oscillation frequencies >  2 kHz

• Modular integration with standard collimation and focussing units

• Low long-term and temperature drift

• Fully digital servo circuitry

• Integrated sensor system with real-time monitoring

• Software-independant interlock interface

• Water and air cooling in a robust housing

Typical Applications:

• Welding of dissimilar materials, e. g. aluminum and copper

• Joining of materials with low weldability, e. g. for power

train or body-in-white components

• Cutting of thick metal sheets or fiber-reinforced plastics (FRP)

Typical Industries:

• Automotive

• Mechanical engineering and metalworking

• Aerospace industry

The welDYNA scan head joins high power with high dynamics. The

high power suitability is supported by ultra-low absorption coatings,

air cooling of the mirrors, strict separation of electronics and optical

path and in addition a set of built-in sensors. Empowered by the

fully digital electronics, the integrated sensors provide extensive

possibilities for real-time monitoring of the system’s operational

state. Light-weight SiC mirrors and highly dynamic galvanometer

scanners of the dynAXIS 3 series enable beam oscillation frequen

cies that are unprecedented in high-power scan heads.

An innovative optical configuration leads to opposing beam

entrance and exit apertures, thus facilitating the integration in

gantry- or robot-based machines, e. g. in the automotive or met

alworking industry.

Layout and Principle of Operation

The solidly designed Collimation Module

includes an adapter for mounting the mod

ule and scan system to a machine. Installa

tion is possible from four sides, providing a

high level of integration flexibility.

Various fiber adapters are offered for laser

coupling. The water-cooled, stainless-steel

beam entrance aperture is corrosion-free

even when using DI water. A scale ring

facilitates manual adjustment of the mov

able collimation optic. This allows precisely

setting the focus position to the scan sys

tem’s nominal working distance, as well as

compensating for tolerances.

Housing

The Collimation Module‘s robust housing is

dust and splash proof – particularly at the

junction to the scan head. A replaceable

protective window in front of the collima

tion optic additionally protects the lens

unit from dust infiltration when changing

fibers. This guarantees a long service life in

industrial environments.

Optional Camera Port

The Collimation Module can be optionally

equipped with a camera adapter for process

control or workpiece position detection. The

light arriving from the workpiece is coupled

out of the laser beam path by an integrated

beam splitter and directed to an observation

port. The laser light itself, however, is

nearly fully reflected by the beam splitter to

establish a 90° angle between fiber-in and

beam-out.
