Laser Production Facility
A 1,350,000 square foot facility was constructed in 2008 to produce lasers, turret presses
and plasma cutting machines.
Flying Optics Concept
In this concept, the raw sheet rests on the cutting
table and the laser head moves in both X and Y
direction. The frame and the gantry are welded and
then stress-relieved to eliminate deviations in the
overall structure that can occur during the welding
process. All moving axis are driven by dynamic low
inertia and high performance and maintenance free
AC servo motors. Precise helical rack-pinion gears
guarantee silent and non-vibrating movement. This
manufacturing process along with a direct mounted
encoder measuring system generates high speed
cutting without a loss of precision or cut quality.
Siemens Drive Systems
Siemens Direct Drive Rack & Pinion (HD)
The stable construction concept allows extremely high acceleration
values. The axes are driven by dynamic low moment of inertia and high
performance Siemens AC servo motors that require no maintenance.
There are no intermediate load transmitting elements between the motor
and the pinion, which otherwise could cause loss of precision. High
precision two-way, hardened helical racks with low running clearance
make it possible to achieve very high acceleration and speeds of 3,970
Siemens Drive Systems
Siemens Linear Motion System (HDL)
A unique design patented by Siemens, the water cooled, IP23-rated
1FN3 allocates the winding and magnets at the primary part, while the
track the motor is traveling on consists of simple steel and does not carry
the magnets. The advantages of this design are:
• Lower costs for long traveling distances
• No magnetic attraction at the track
• Faster acceleration and deceleration and speeds
• Better positioning accuracy
Shuttle Table
The electric-powered shuttle table is fast, robust and easy to adjust. It has low power consumption, no hydraulics
and low maintenance.
The table is easily accessible from four sides, with ergonomic manual loading and unloading.
Intelligent Auto Focus
Capacitance Cutting Head
The HP SSL head, being designed for high cutting speeds, is
mechanically rugged and provides a stable signal for the
distance sensors, thus enabling high cutting speeds to be

Fume Extraction System
Efficient fume extraction by means of shutters which are controlled in
accordance with cutting head position results in more efficient use of the
filtration system. Therefore a smaller, lower cost system can be used.
Six fume extraction zones deliver improved suction flow design.
• Smaller air flow from dust collector
• Low electrical consumption
• Smoke and dust free machining area
Safety & Protective Measures
The laser cutting system, machine and CNC controller are equipped with safety devices. These switches and
sensors, on one hand, protect the operator from hazards, and on the other hand, counteract damage to the
system. For example, incorrect path measurement programming or collision between the workpiece and the
machine. A diagnosis system keeps the operator informed about the current status of the system and allows him
to intervene in the dialogue to make corrections that remedy these faults. The steps required for the solution
appear as plain text on the controller screen.
The working area is guarded by light guards. These guards can be interrupted to gain free access for: inserting a
new sheet, lens and nozzle replacement, general maintenance and for other special purposes. During the laser
cutting operation the safety devices are electromagnetically locked, in order to prevent an accidental triggering of
the machine’s EMERGENCY STOP function. The machine’s safety equipment corresponds to the CE guidelines
currently in force. The laser head is guarded along the Y axis by flexiglass material which allows clear vision for
the cutting area.
Used to cool the laser source, mirrors and the cutting
head. For quality cutting it is necessary that the
temperature of all the equipment used in beam
delivery is very stable. Cooling also directly affects
and increases the life of consumable parts. Proper
cooling allows the mirrors, lens and nozzles to be
used longer.
• Limitation of power consumption by the use of
energy saving techniques
• Closed circuit system – no possibility of calcium
• Flexible adjustment of water temperature and
• Reduction of water costs to zero
• Infinitely variable additional speed control
• Vibration free, low noise, high efficiency scroll
• Silent running condenser and casing
• Liquid cooled, seal free, non-wearing pumps
Automatic Sheet
Position Locator
The software includes a sheet locator feature that
allows taking highly accurate references on the sheet
metal position on the table, via a capacitive sensor. If
the sheet position is different from the theoretical one,
the part program must be adapted to the real position.
Stress Relieved
Both the mainframe and gantry are stress relieved
after the welding process to eliminate deviations in
metal geometry that can occur during the welding
Fiber Laser Advantage
Diode Pump Fiber Laser vs Slab CO2 Laser
Less moving parts creates more efficiency and reduced maintenance
Fiber Laser Advantage
High Beam Quality
Smaller focus diameter with better Beam Parameter
Product (BPP). Fiber laser can be focused to a spot
the size of 1/10th the diameter of the CO2 laser.
The difference in brightness results in 100 times
higher power density at the workpiece. Therefore
cutting capacities between a CO2 and Fiber resonator
should not be compared on a 1:1 (1kw fiber laser cuts
as fast as 3kw CO2 in the range of .118-.196”
stainless steel). Cutting thick materials from
.590”/15mm up to .787”/20mm, the laser power has to
be increased to cut the same speed as a lesser
capacity fiber laser.
Smaller focus can produce higher power density or a
longer focus length, which makes the process more
Moreover, the operating wavelength of around 1
nanometer gives at room temperature about 7 times
higher absorption in metals as 10.6 nanometers. Low
reflection makes it easier to cut materials such as
brass and copper.
Smaller and lighter optics can be used (30mm
diameter lens, 37.6mm at CO2)
Transmission of the laser beam through fiber cable
versus mirrors and beam path concept of the CO2,
increase efficiency and eliminate maintenance
Fiber Laser Advantage
Fiber Laser Advantage
IPG Fiber Laser
The dynamic operating range of IPG’s low-ordermode kilowatt class fiber lasers is available from 10%
to full power with no change in beam divergence or
beam profile throughout the entire range. This allows
a single laser to be utilized for both high and low
power applications. IPG lasers’ divergence
specifications are far superior than other lasers and
allow the use of long focal length processing lenses
for vastly improved depth of field, less damage to
optical components. The units can be supplied with
fiber lengths to 330 feet, different fiber diameters.
Fiber lasers have a monolithic, entirely solid state,
fiber-to-fiber design that do not require mirrors or
optics to align or adjust, and are typically smaller and
lighter in weight than traditional lasers, saving
valuable floor space.
Low Cost Operation
Space Savings
Energy Savings
In the case of an average cost of $33 per square foot,
the annual savings is approximately $1,200 for the
resonator, electrical box and chiller.
Fiber Laser consumes 40.8kw less electricity per
hour. Assuming 1 kwh = $0.119, and the machin
operates 5,000h/year, Fiber electricity consumption is
$23,800 less yearly.
Energy costs of 4kw Fiber Laser at nominal power is
less than the standby costs of CO2 Laser (4kw). The
efficiency of fiber laser corresponds to the
requirements for “Green Laser Power.” An efficiency
of >30% is common for the advanced IPG Fiber Laser
Consumable Savings
The fiber laser is maintenance free in contrast to the CO2 Laser. There are no parts which have to be replaced permanently and
regularly, like laser tubes, vacuum pumps, output couplers, ventilators or laser gases.
