Dallas, Texas - June 5, 2005 Humanetics China purchases new FPL-6 laser machine Success in today’s sheet metal fabrication industry depends not only upon an equipment manufacturer’s ability to meet its customers’ current needs… but also upon its vision and strength to anticipate and respond to future changes in the marketplace. The FPL-6 is a breakthrough in sophisticated high-speed laser cutting for sheet metal fabrication, creating enhanced production with superior speed, accuracy, and part quality. The Finn-Power laser is a flying optics system with a working area of 3000 mm (118") X axis; 1500 mm (59") Y axis; and 100 mm (3.9") Z axis. Maximum positioning speed of X/Y axes simultaneously up to 300 m/minute (11,811"/min). And, Finn-Power’s unique Ping Pong repositioning movement allows smooth and efficient transitions for increased productivity.     The Finn-Power Laser is designed by using innovative linear  drive motor technology to allow maximum speeds, even in small notches or narrow contours. Finn-Power provides a new level of high-speed performance with regard to machining dynamics, contour accuracy, and process safety.   Technical Specifications FPL 6 Laser Flying Optics / Moving beam system Working area X-axis: 118” (3000 mm)   Y axis : 59” (1500 mm)   Z axis : 3.9” (100 mm) Max.

The values are based on an area from 39.37” x 39.37” (1 meter x 1 meter). (2) Maximum cutting speed depends on part configuration and material thickness (3) Maximum gas pressure is depending on the specifications of the focusing lenses.   FRAME The FPL6’s unique frame design provides greater rigidity to accommodate the highest acceleration and deceleration rates without compromise.  The rigid frame construction allows Finn-Power to equip the laser with a high speed linear drive system.  This provides higher path accuracy, thereby increasing production. COMPACT DESIGN The FPL-6 has a compact design with the resonator and CNC built into the structure. The positioning of the shuttle tables is possible on one of two sides of the machine. This is beneficial when plant layout or production flow require system layout flexibility. SAFEGUARD The shuttle tables are safeguarded by light beams around the shuttle table. SHUTTLE TABLE The productivity of the cutting system is increased by an automatic shuttle table system that allows loading and unloading of the material during and after the cutting operation. The shuttle table automatically moves the processed sheet into the unloading position and a new sheet on the other table moves into the cutting area. No extra safety light beam is required. Safety doors allow the operator to access the shuttle table while the system is running. Positioning of the shuttle tables is possible on one of two sides of the machine (A: front or B: back). This is beneficial when plant layout or production flow require a specific position. SCRAP BINS Two(2) scrap bins are located under the shuttle table for easy removal of any small pieces of scrap. COMBINATION CUTTING TABLE Both cutting tables are equipped with pins and/or support grids for more flexibility and support. They are designed to accommodate a maximum work piece weight of 800 kg (1,760 lbs.). LASER RESONATOR The FPL-6 is designed with only two external direct, water-cooled copper mirrors that are used to guide the laser beam onto the focusing lens. Laser beam protection tubes are continuously pressurized by specially filtered and dehumidified/dried air. 3500 Watt Laser Resonator Integrated adaptive telescope for constant cutting quality and cutting parameters over the entire working area.   Integrated fast laser power measurement.   Extended laser preventative maintenance interval   VACUUM PUMP &  RESONATOR TURBINE Gas circulation by the oil-free, radial gas turbine and the oil-free vacuum pump is an advantage of the 3,500-watt CO2 laser. Oil-free bearings eliminate the risk of contamination into the resonator. AUTOFOCUS CUTTING  HEAD To minimize set-up time, an advanced, high-pressure cutting head is integrated into the system.  The constant distance between the material surface and the nozzle is achieved with a non-contact, capacitive, integrated sensing unit. The cutting head does not have to change when a focal lens change is required. Only a new lens cartridge has to be inserted.  The lens mount can be changed in seconds by this cartridge technique. Cartridges are available for focal lengths of 5" and 7.5".   Additional features of the cutting head include: Automatic fast calibration including nozzle surface cleaning Connections for three different assist gases with automatic regulation up to 25 bar Capacitive (non-contacting) measuring system   CONTROL  SYSTEM The Finn-Power FPL-6 Laser is equipped with the state-of-the-art Siemens Sinumerik 840 D CNC-controller, with 14" touch screen and integrated Man Machine Control (MMC) interface. The NC program memory in Sinumerik 840 D is 1.0 MB. LINEAR DRIVE  SYSTEM The Finn-Power FPL-6 Laser is designed with digitally-controlled linear drive motor technology to allow high-speed operation, high acceleration, as well as highest contour accuracy.  High-path accuracy is achieved through no-friction components in the drive system.   NC Express Programming Software NC Express -- A scaleable application.

Laser Link A database with a large number of cutting parameters for various materials is stored on the Laser Parameter Manager in the MMC Computer.  The parameter can quickly be optimized or edited for new or different materials.  In addition, the Finn-Power Laser machines offer the operator the possibility to change or optimize laser parameters online like feed rate or cutting gas pressure, etc. Due to this unique feature, the laser cutting results can be optimized even during the laser process. Man Machine Control (MMC) The MMC with a hard disc drive for NC programs and Laser Link software provide an information system with alarm code explanation and user manuals. The integrated diagnostic system helps the operator monitor the different machine functions as well as quickly identify and assist to correct possible malfunctions.
