8 Machine durability and reliability. Beam Delivery System The beam delivery system is enclosed in a constant volume, balanced chamber with two bellows each for X and Y motion. One bellows contracts while the other expands during cutting head travel to maintain a constant internal volume. The beam delivery system bellows is purged with dry, filtered, compressed air. This positive pressure beam purge assures a dry, clean environment for beam delivery, which prolongs mirror life in the demanding environment of many fabricating shops, and ensures stable power at the workpiece. The resonator and beam delivery systems are mounted on the main frame, providing beam delivery stability, compactness of design and no special foundation requirements.
The solid heavy-duty construction of the CL-7A Laser Cutting System provides an excellent machine foundation for the resonator, beam delivery system, machine drive and motion controls. The frame is fabricated from thick steel plate with exceptional torsional stiffness to provide many years of consistent, accurate production. The CL-7A advanced design incorporates far fewer parts in the resonator, drive and control systems. Simplification of the power supply improves resonator reliability and maintainability. Fewer optics in the resonator and beam delivery system results in high reliability and lower maintenance. A reliable fiber optic bus replaces multiple wiring harnesses thus reducing susceptibility to electrical noise and improving reliability. Diffusion Cooled Resonator This patented resonator design consisting of front and rear metal mirrors and two parallel RF electrodes, generates the beam in an extremely tight vacuum chamber. Excitation of the laser gas takes place in the gap between these electrodes, which are water cooled to dissipate the heat generated in the discharge. The electrodes and resonator optics are mounted at 45˚ to the horizontal to produce a linearly polarized beam, minimizing additional optics. The RF generator is directly coupled to the electrodes, thereby achieving delivery of the high energy without using any cables. The simplicity and elegance of this design yield high reliability. Rugged, Rigid Frame For Precision Machinery Cincinnati Incorporated pioneered all steel plate construction for precision machinery over 75 years ago. The frame is fabricated from 3 /4" to 1 1 /2" steel plate. It is stress-relieved before machining to ensure that critical dimensions remain stable. The mass of the frame effectively dampens vibrations from other equipment, a requirement for optical stability. The load frame is a separate component which allows material handling to occur without affecting the cutting process. 9
