    Lens Savers for protecting the focal lens

    Has any one ever used Lens Savers? It basically looks like a clear piece of glass that fits below the focussing lens. It is supposed to protect the bottom of the lens from spatter thus prolonging lens life. I am skeptical but would try it if someone knows that it is a good product. Anyone try...

    Blue flame focusing procedure

    Does anyone know what actually causes the "Blue Flame" to occur while performing a focussing procedure? Is it a chemical reaction between the nitrogen and the stainless steel? Just Curious.

    Cleaning Laser Slats

    Also, using welder's anti-spat spray will help keep the slag from sticking to the slats but it does nothing to prevent decay due to the laser beam actually hitting the slat itself and melting it. We just made a "rake" with small slots in it that when dragged across the laser slats knocks most of...

    What is typical laser lens life and other lens related ?'s

    Hello, I am running 2 Mazak sheet lasers. 1 2.5kW and 1 2.0kW. Both machines are the STX510 S/C. We are using II-VI ZnSe Plano Convex lenses, 5" focal length. We run both machines around the clock 7 days a week. We cut mainly 16 gauge mild steel. Occasionally aluminum and S.S. We noticed that...

    Anyone using SCS processed sheets with lasers? Success?

    Hi, I have heard that SCS processed steel sheets are capable of being cut faster and cleaner with lasers due to their high degree of flatness. I have read on the SCS website that you can actually cut 2 sheets at the same time without them welding together. Has anyone used this material yet? I a...

    More LC1212 questions

    msandoval, I have read your posts about using the "edge data" screen to pulse cut around corners before. Is this method equivalent to "power ramping" on a Mazak? I have used corner looping in the past but I am interested in trying the power ramping. Would you suggest one method over another...

    laser cutting plastic questions

    Yes, there definitely are laser systems that utilize fiber optics for beam delivery. These allow integration with articulating arm robots for real 3D processing of parts. I am not familiar with any specific brands but I know that most fiber optic lasers use a YAG (yttrium aluminum garnet) laser...
