CONTINUOUSLY SWEEPING LASERS: L-740 Ultra Series Lasers:

L-743 ULTRA-PRECISION TRIPLE SCAN® LASER (3 laser planes - 3 axis)

DESCRIPTION
The L-743 Ultra-Precision Triple Scan® Laser is our most versatile and powerful machine-tool alignment laser. It has been designed specifically for 3-5-axis machining centers to measure and correct machine geometry. In most cases, all it takes is one setup to measure flatness, straightness, parallelism and squareness of the main axes of most typical machining centers.

The L-743 has 3 rotating laser planes that are perpendicular to 1 arc second (0.00006"/ft or 0.005mm/M) and flat to 1/2 arc second (0.00003"/ft or 0.0025mm/M) in a 360º sweep and 1/4 arc second in a 90º sweep.

The L-743 features 1-arc-second level vials, a powerful magnetic base for stable mounting and pitch, roll and yaw adjustment (both course and fine) for setting the laser parallel to reference points.

Since the system provides live measurements, any errors that are found can be fixed with the same setup. The laser mounts on a machine or stable base so that the laser plane can project the measurement reference out to 100' (30.5 meters) in radius for each laser plane

APPLICATIONS (for alignments with tolerances of 0.00002"/ft or 0.0017 mm/M or greater)

• Machining centers (HBMs, VBMs, HMCs, VMCs, VTL's, gantries and surface grinders)
• Automotive transfer-line wing bases
• Injection molding machines and presses
• Aircraft assembly (seat track alignment, setting water, butt and station planes, wing-to-body and body-to-body join alignment, etc.)
• Roll parallelism in:
  - Paper mills,
  - Printing presses
  - Film lines
  - Blown-film lines
• High-precision, laser and water-jet cutting machines
• Circuit board drilling machines
• Measuring and aligning:
  - The flatness of almost any surface (squares, frames, ways, flanges, circles, etc.)
  - The squareness of up to 3 surfaces
  - The straightness of horizontal and vertical surfaces
  - The straightness and flatness of horizontally and vertically traversing axes
  - The parallelism of horizontal and vertical surfaces even if those surfaces are 100 feet (30.5 meters apart)
• Checking plumb of a vertical surface up to 100 feet (30.5 meters)
• Checking way twist and parallelism between horizontal surfaces
• Checking way twist and parallelism between vertical surfaces
• Measuring surfaces up to 200 feet (61 meters) long with 1 setup
