For the last ten years, HACO
has built up a real expertise in industrial Laser Cutting Machines and
applications. To meet the ever-growing laser market and its cutting quality
requirements, HACO has developed compact, high performing and reliable CNC Laser
Cutting Centres.
The monobloc frame structure,
with built-in laser source, integrated electronic, electrical, pneumatically and
mechanical components results in a stable and compact machine.

The HACO Raptor CNC Laser
Cutting Machines is of the 'flying optics' concept, having many
advantages.
The machines' inertia
remains the same for all materials thickness and to be cut, leading to
an optimum cutting quality over the entire cutting table due to a
perfectly controllable cutting speed and accuracy.
Furthermore, the
materials to be processed must not be clamped or fixed, which eases the
materials handling.
As the material sheet is
not moving, a scratch-free machining is guaranteed, as well as the
possibility to cut through less stable or thinner materials.
Also 'tinger' part
nesting is allowed, leading to less material waste.
With the window-based
Siemens 840D CNC Control, the operator has interactive control of all
programmed process values such as speed, gas pressure, laser power at all
times.
A built-in conveyor belt
collects all scrap and small pieces into the scrap bin in front of the
machine. |

The laser
source is a 'Fast Axial Flow' CO2 Laser with DC-discharge.
The
laser-active medium (or cavity") in a CO2-Laser is a gas
mixture of CO2, He and N2. In the near-vacuum
cavity, this gas mixture converts electrical energy (high voltage
discharge) into Laser light. The oscillation of this laser light between
two or more mirrors, the so-called 'optical resonator', amplifies the
laser light and turns it into a high-power beam. |

A CO2
Laser emits infrared radiation with a wavelength of 10.6 µm.
The fast flow
the laser gasses is generated by an oil-free turbo-pump with integrated heat
exchangers. The use of the especially developed laser-grade LASAL 97 premix gas,
reduces the gas supply to a single bottle.
The high
voltage supply has been especially developed and has a modular design.
Each module has
identical characteristics, cutting down maintenance duration and costs as no
special fine-tuning is required. The high voltage power supply uses modern IGBT-techniques
and an active feed-back control of the output power of each separate module,
leading to a extremely stable and constant total output power.
Together with
the PID-controlled system pressure, this leads to a laser power stability and
repeatability of ±1.5% over the full range.
The resonator
itself is a kinematically suspended invar-frame, nearly eliminating 'warming up'
of the laser source before actual cutting can start.
The telephone
and polarization optics of the HLT-3000 are mounted on the resonator frame
itself, having many advantages. It results in a constant high axial accuracy
with respect to the out-coupling mirror, leading to a ready-to-use output beam
with constant cutting for an optical of 15 meter and brings the beam adjusting
procedure after the machine mirror maintenance to a minimum effort.
The laser
source control unit has many pre-defined pulse programmes, but also allows free
pulse programming.
It has a
full-diagnosis software and informs the operator of its status and actual laser
program on the screen of the CNC control.

The intelligent SINUMERIK 840D is
a highly sophisticated 'open' CNC Control System.
Together with the SIMODRIVE 611
digital converter system and the SIMATIC S7 programmable controller, the
windows-based Sinumerik 840D provides a complete digital system is suitable for
complex machining tasks and which excels with its fine dynamic and precision.

FINEST
CUT for WINDOWS '95 or NT
To an
outstanding machine belongs a likewise outstanding
programming software, which supports all technological
possibilities of the machine. The proved programming
system FINEST CUT is well-tuned to the HACO CNC Laser
Cutting Machines. The homogeneous user interfaces and
the use of modern tools lead to a user-friendly and
efficient programming.
The
unique catalogue for leads in/out included in FINEST CUT
contains a large number of different figures. The
automatic association of leads in/out is done in
relation to the contour area.
The
management for part-, material-, technology- and machine
data leads to a comprehensive automization for the
sequencing of contours, for the generating of leads
in/out and for the association of different cutting
conditions in relation to the contour area.
|
 |
|
The
possibility of manual manipulation leads to individual,
customer specified results.
Plausibility
checks ensure a correct generation of CNC -data and help
to prevent materials loss (scrap percentage).
Easy
manual nesting enables an effecytive optimization of
sheet utilization. The FINEST CUT extension packages
PROFESSIONAL and PROFESSIONAL PLUS offer further
functional enlargements. Automatic Container Nesting and
Fully Automatic Contour Nesting FINEST AUTONEST cut down
expensive programming time and improve material
utilization.
The
integrated interface DXF-in produces compatibility to
most of the usual CAD systems.
Additional
interfaces are available (DXF-out, IGES, DSTV, ESSI,
...). |
