At Labelexpo Americas 2004 in Chicago, AB Graphic International (Bridlington, East Yorkshire, England; www.abgint.com) introduced the Sabre Extreme MK2, a laser label die cutting unit that offers job changeover in seconds and minimal wastage because real-time tracking guarantees perfect register of print to cut.

Optimized for digitally printed webs, the unit offers advantages over conventional die cutting, such as no tooling. Once the die line is downloaded from the prepress department, the image is stepped across the web, and the power is selected, the MK2 is ready to start producing. It’s so fast and easy you will be producing finished labels while the competition is ordering tooling.

The Sabre Extreme features a Synrad (www.synrad.com) Firestar 200W CO2 laser that can kiss-cut, through-cut, and/or perforate up to 20,000 hours MTBF.

The 3XB 3-Axis Scan Head from Nutfield Technology Inc. (Windham, NH; www.nutfieldtech.com) offers laser system designers small spot sizes, large scan fields, and the ability to mark on contoured surfaces. According to the company, this product is the only 3-axis scan head that allows for different field and spot size combinations by simply turning a knob to adjust the spacing between the translator and objective lens. The lens translator houses an expander lens, which moves linearly along the axis of the beam to correct for focus, in real time, as a function of an X/Y position within the scan field. Lens sets are custom selected to accommodate a variety of laser beam apertures and wavelengths, and to optimize spot size and field size requirements.

Productive laser cutting

Bystronic (Hauppauge, NY; www.bystronic.com), has introduced two products for increased productivity: the Bylaser 5200 ARC laser and the Byspeed 4.4 cutter.

CAD conversion software

Software from J P Sercel Associates (JPSA, Hollis, NH; www.jpsalaser.com) converts CAD file information into macro processes and programs for performing direct write functions with the laser beam. Users create a CAD drawing that represents paths or patterns for the laser to follow. The software then takes that information and automatically programs the machine to scribe, dice, pattern, text-mark, cut out parts, and perform other applications involving the use of a laser as a cutting tool. The Windows-based software works with JPSA’s excimer and DPSS workstations on a variety of substrates. It also works in conjunction with JPSA’s standard laser control software.

High-performance digital positioners

The Logix 32001Q and 500si series positioners from Flowserve Corp. (Dallas; www.flowserve.com) are easy to configure and calibrate, and offer easily accessible diagnostic information to minimize plant downtime. LEDs provide instant information relating to internal diagnostic codes, and a direct user interface enables the positioner to provide fast and easy configuration.

Fiber laser-powered stencil cutter

According to Synova (Ecublens, Switzerland; www.synova.ch), its LSS 800 F stencil cutter cuts from 1 to 10 holes per second (equivalent to 36,000 apertures per hour) without any heat damage, burrs, or oxidation. Featuring the company’s Laser-Microjet technology, the LSS 800 F uses a fiber laser source uniquely suited for thin, high-precision stencils and masks. The applied fiber laser emits pulses at a repetition rate of between 20kHz and 50kHz, with a pulse duration measured in nanoseconds. This results in a very fine cut, a higher cutting speed, and higher accuracy as compared to a conventional laser source. The fiber core diameter, 100 μm, also enables the user to apply thinner water jets (below 30 μm).

Low-power CO2 lasers

According to Coherent (Santa Clara, CA; www.coherent.com), its Diamond C-55 and Diamond C-70 CO2 OEM lasers provide more than 55W and 70W of output power, respectively, at 10.55 to 10.63 μm. Their M2 <1.2 (<1.3 for the C-70) beam quality makes them suitable for medium- to high-volume marking, engraving, and desktop manufacturing. The C-55 was built using the same laser cavity as its predecessor, the GEM-50. However, its power supply RF driver is integrated into the same housing as the laser head, making the unit more compact. Also, Coherent says the C-55 provides 10 percent higher power than the GEM-50. The C-55 comes in air-cooled and liquid-cooled versions and features a rise time of less than 60 μs. The C-70 uses an asymmetrical optical cavity to obtain 70W of power from the same integrated package and comes in elliptical and circular versions.

Laser regulator

CONCOA’s (Virginia Beach, VA; www. concoa.com) 601 Series laser gas delivery system regulator incorporates new M2 technology to minimize atmospheric contamination caused by deposited contaminates that reduce laser power output and distort beam-mode quality. The company says stable emission and higher resonator efficiencies are achievable because of the system’s low internal volume construction and smooth flow paths that eliminate dead space as potential entrapment sites for moisture or hydrocarbons. The 601 Series also offers an optional integral purge assembly and an internal check valve that reportedly guarantee gas purity and lower maintenance costs.

Absorbing head detector

Ophir Optronics’ (Wilmington, MA; www.ophiropt.com) Model 30(150) A-SV Volume absorbing detector head offers a damage threshold for power density of 100KW/cm2 and a damage threshold for energy density for nanosecond pulses of 1J/cm2, making it suitable for use with very hard-to-measure beams that have extremely high power and energy density. In addition to measuring up to 30W continuously and 150W intermittently, the Model 30(150) A-SV offers a spectral range of 0.19-12μm, a power range of 50mW-150W, and an energy range of 50mJ-200J.
