4 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 ConceptIn 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.
5 Siemens Direct Drive Rack & Pinion (HD) Siemens Drive SystemsSiemens 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 ipm.
6 Siemens Linear Motion System (HDL) Siemens Drive SystemsSiemens 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 distancesNo magnetic attraction at the trackFaster acceleration and deceleration and speedsBetter positioning accuracy

9 Fume Extraction System FeaturesFume Extraction SystemEfficient 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 collectorLow electrical consumptionSmoke and dust free machining area
10 Safety & Protective Measures FeaturesSafety & Protective MeasuresThe 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.
11 Features Automatic Sheet Chiller Position Locator Stress Relieved 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 techniquesClosed circuit system – no possibility of calcium depositsFlexible adjustment of water temperature and pressureReduction of water costs to zeroInfinitely variable additional speed controlVibration free, low noise, high efficiency scroll compressorSilent running condenser and casingLiquid cooled, seal free, non-wearing pumpsThe 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 RelievedBoth the mainframe and gantry are stress relieved after the welding process to eliminate deviations in metal geometry that can occur during the welding process.
12 Diode Pump Fiber Laser vs Slab CO2 Laser Fiber Laser AdvantageDiode Pump Fiber Laser vs Slab CO2 LaserLess moving parts creates more efficiency and reduced maintenance
13 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 ” 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 stable.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
15 Fiber Laser Advantage IPG Fiber Laser The dynamic operating range of IPG’s low-order-mode 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.
16 Low Cost Operation Space Savings Energy Savings Consumable 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 technology.Consumable SavingsThe 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.
