Laser source
ACSYS offers various laser sources for a wide range of
materials and processing methods. With a power range of
0.5 to 1000 Watts available, we can find the ideal confi-
guration for every conceivable application. Our portfolio
encompasses everything from fiber lasers and diode-pumped
lasers to CO2 lasers, that may be deployed either as pulsed
laser or as cw-laser beam source. All beam sources used in
laser machines by ACSYS are extremely low-maintenance, of
exceptionally high durability and almost always air-cooled.
ACSYS laser experts can assist you with their profound know-how
and comprehensive testing in finding the most suitable laser
source, or in individual cases even a mix of different types of
beam sources, that will fulfill your requirements in the best
possible way. The included chart provides an overview of the laser
sources and wavelengths in reference to the absorption rates of
various materials.
Prefect symbiosis of laser and machine.
ACSYS laser machines are of a modular design. This allows the
ACSYS engineers to perfectly fine-tune the entire system to your
particular requirements. Furthermore, ACSYS is offering a wide
range of optional modules, to broaden the scope of the laser
system‘s application even further.
Laser
The heart of the material processing systems by ACSYS.
1. Circumferential, seamless laser en-graving on a cambered silver ring. 2. Micro-Laser engraving of a punch for authenticity certification of jewellery. 3. Laser frosting – Various surface frostings. A patent pending method to create realistic sand-blaster effects, developed by ACSYS.
4. Laser engraved punching die (reverse).
5. Laser engraved and laser frosted punching die (obverse).
6. Punched coin (obverse and reverse).
Design: The designer creates a drawing.
Model / CAD Modelling:An oversize model is created based on the sketch.The model can be created on the computer with CAD software. Then the file can be di-rectly engraved in 3D onto the tempered die.
Reducing / digitizing: The oversize model is reduced to coin size on the reduction machine. The oversize model is digitized with an ACSYS 3D scanner. Existing coins can also be digitized and duplicated with an absolute accuracy of 2 μm.
Stamping Dies
Every coin begins as an artist‘s sketch.
In the traditional process, a plaster model of the coin
image about 20 cm in diameter is then produced.
This model is reduced through repeated casting
processes on the reduction machine to produce
a coin-size synthetic resin model. Up to 36 hours
are required to mill all details of the model into
the untempered steel. Then the engraver uses the
traditional method to work out the contours and fine
plastic details on the reduced positive steel die. The
reduction is next tempered and the positive forging
die is produced by repeated punching. Finally the
forging die is used to produce the actual negative
die. After punching, this die is rotated into the
correct shape, tempered and hard-chrome-plated.
Then it is frosted manually.
ACSYS offers a number of advantages compared
to the traditional method and engraving with con-
ventional CNC machines. ACSYS 3D scanners
make it possible to digitize hand crafted oversize
models for advanced processing by computer.
Existing coins can also be easily digitized, saved and
reproduced by ACSYS using 3D laser engraving.
Illustration: : Traditional method : Laser supported method

Engraving / 3D laser engraving: The reduced positive steel stamp is revised by the engraver. Digitized data can be laser engraved directly into the tempered die in a three-dimensional process with the laser.
Punching: The stamp is tempered and punched into an untempered steel piece with great force.
Tempering / frosting: The negative die that has been created is rotated into shape, tempered and chrome-plated. Then a partial frosting is applied. The high-precision dual camera preview of ACSYS defines frosting in advance on the screen and applies a wide range of textures with μ precision.
The laser is capable of engraving directly into the
previously tempered steel of the stamping die. The
tool changes required for CNC engraving, costly
in terms of time, and the subsequent pressing and
tempering are completely eliminated.
The laser also has great importance in the area of
frosting. The high-resolution dual camera systems of
ACSYS allow for precise definition of specific areas to
be frosted in advance on the computer screen. The
laser can then apply a wide range of frosting textures
on the die with μ precision.
Advantages of the Laser:
- Only one tool needed.
- No tool wearout.
- No tool breaking.
- Only one clamping operation.
- New materials possible, better durability.
- Shorter set-up times.
- Reverse engineering.
- Customization through digitizing.
Digitizing
Leading edge technology – that‘s what we offer. Impressive
machine solutions from ACSYS deliver the greatest accuracy,
precision and repeatability. Digitizing is based on the conoscopic
holography method, allowing extremely precise 3D digital images
of all surfaces, plaster models, dies or working directly from coins
and medals.
The resulting 3D file can be used for production and reproduction
and can be easily processed in the CAD software. The advantages
of this non-contact method are high speed and small measuring
grid distances. Absolute accuracy of 2 μm can be achieved with
the replaceable lens system. Conoscopic holography offers the
greatest precision and repeatable accuracy over a wide range of
applications.

3D laser engraving allows the three-dimensional surface ablation
on a wide range of materials with outstanding quality.
Since there is no contact whatsoever between the laser and the
workpiece, the advantages over conventional CNC engraving are
obvious: No tool wear, no tool changes, and no tool breaking.
The high level of precisely charged laser energy makes it possible
to engrave previously hardened materials while providing a
working beam diameter of up to 20 μm.
Our unique ODC - Online depth control makes it possible
to control the removal of material. The target depth and
actual depth are continuously compared and the 3D laser
engraving system is controlled to the exact engraving depth.
Free form surfaces can be scanned and digitized with the ODC
module, and can also be easily processed in the AC-LASER
Software.
Especially in the minting industry, our machining centres in
combination with the powerful AC LASER Software offer the highest
level of efficiency. From file creation to output on the laser, all
details are perfectly co-ordinated to ensure an intuitive workflow.

Frosting & Surface structuring
ACSYS laser systems ensure high-precision frosting of punching
dies for commemorative coins and circulating coinage. The laser
output can be precisely adjusted, making it possible to achieve
an evenly smooth surface texture. Areas to be frosted can be
conveniently defined graphical by mouse at high magnification
on the system monitor.
Lasers open up entirely new possibilities in terms of design. In
addition to the precise surface frosting, unlimited other textures
with interesting visual effects can be applied.
A great advantage is the absolute reproducibility, since any
frosting layout can be saved as a file and then automatically
transferred to other dies at any time.
In comparison to the conventional process, selective frosting of
dies for coins or medals is much more economical with a laser
machining system. Overall process time is greatly reduced and
constant quality is guaranteed.
