5-Axis Laser Machine drills, cuts, and welds 3-D parts.

Prima U.S., Inc. Sep 17, 2002

Press Release Summary:

Operating at speeds to 800 in./min in X, Y, Z axes, Model 790 BeamDirectorÃ‚Â® is accurate to Ã‚Â±0.0004 in. per 20 in. throughout its entire work envelope. Assembled atop granite base, it incorporates rigid X and Z axis assembly and sliding Y axis arm that eliminates droop. System utilizes DC brushless motors, digital motor amplifiers, and integrated Automatic Focus Control(TM) (AFC). Its 2 in. clear aperture allows integration of C02, Nd:YAG, and CW:YAG lasers.

Original Press Release:

Laserdyne 790 BeamDirectorÂ® Features Volumetric Accuracy for Laser Drilling, Cutting, Welding 3-D Parts for Aerospace, Automotive, Appliance Applications

Maple Grove. Minnesota: Laserdyne's new 790 BeamDirectorÂ® is a 5-axis laser machine designed to drill, cut and weld medium to large 3-D parts with a moving beam motion system.

Operating at speeds up to 800"/min in the X, Y, Z axis (0-2000 mm/min), the 790 BeamDirector is accurate to Â± 0.0004" (0.01 mm) per 20" (500 mm). This accuracy is throughout the system's work envelope (called "volumetric accuracy") and not just in a small area known as the sweet spot common to most other multi-axis laser systems.

Designed, built and tested to ASME B 5 5.54 and ISO 230 standards, the 790 Beam Director is assembled atop a rigid granite base. It has an extremely rigid X and Z axis assembly and a sliding Y axis arm that eliminates droop. By using DC brushless motors and digital motor amplifiers, high acceleration and speed are achieved with high accuracy and minimal deflection or vibration due to the unitized assembly and superior system rigidity.

Field-Proven Technology

The 790 BeamDirector uses the field proven and time tested direct drive Laserdyne Systems BeamDirector with fully integrated Automatic Focus Control (AFC)(TM). The 35 mm (2 inch) clear aperture allows integration of high powered C02, Nd:YAG and CW:YAG lasers. All of the Laserdyne Systems BeamDirectors are offered with exclusive 5 year, unlimited hours warranty covering crash related damage.

Programming the 790 BeamDirector includes online TeachVision(TM) (optional) or off line CAD/Post Processor software (optional) for quick implementation of part design to the shop floor or fast and easy program changes.

Typical 790 BeamDirector customer applications include combustion liners, exhaust and heat shields, tubing and hydro-formed parts, nozzle guide vanes and blades, stamped parts and spinners, automotive prototypes, and white goods.
