PULSED ND:YAG LASER DRILLS DEEPER AND LARGER HOLES
PRIMA North America, Inc. (Champlin, MN), the North American subsidiary of PRIMA Industrie, S.P.A. (Torino, Italy), a world-leading manufacturer of industrial laser systems, introduces its newest model the Convergent Laser CL-R pulsed Nd:YAG laser.
?This next generation laser was designed to be an in-place replacement for the JK704 lasers used by Laserdyne Systems customers around the world,? according to Terry L. VanderWert, president of PRIMA North America. ?It gives existing system users a replacement option for the JK704 at the same time providing an upgrade opportunity for increasing the performance of their system. While there appears to be a number of processing advantages when using this laser, including higher throughput and the ability to produce deeper and larger percussion drilled holes, the main thrust of the program is to provide customers with a laser that will be supported for many years to come.?
Users of earlier model Laserdyne 780, 890 and 790 systems will be offered a turnkey retrofit package including complete on-site installation and startup assistance.
The laser combines up to 50 kW peak power with low divergence resonator optics to produce a high intensity laser spot for:
? Drilling holes up to 75 mm (3 in) in length.
? Drilling 3 mm (0.12 in) long holes at 10 holes/second on the fly.
? Cutting at 300 mm (12 in)/min or to 20 mm (0.8 in) in depth.
? A long depth of focus enables deep holes to be drilled with reduced taper. Special pulseshaping techniques can be used to improve the geometrical quality of holes drilled by single laser shots ?on the fly.?
When retrofitted the CL-R will be compatible with existing beam delivery hardware and existing software programs, and will operate with existing chillers. According to Laserdyne, retrofit applications have the potential for increased processing efficiency and lower operating cost, depending on the application, the system?s condition and other factors. For example, longer life lamps are used in the new CL-R laser, which have been reported by users of both lasers to lead to increased shot count before replacement. They also have a lower replacement cost.
