The L-742 Dual Scan® Ultra-Precision Roll Alignment Laser
With two continuously sweeping, ultra-flat, orthogonal laser
planes, the L-742 Dual Scan
®
Laser is ideally suited to roll
alignment applications. The laser can be configured at the factory
to have either 2 vertical planes (typically used for roll alignment),
or 1 horizontal and 1 vertical plane, allowing a user to not only
measure, but also fix alignment problems in a fraction of the time
needed with conventional methods.
Using the L-742 you can quickly and easily check and correct
horizontal roll parallelism of even the tallest process mills, pick
up and check offset centerline benchmarks, and perform similar
alignments with increased accuracy and shorter setup times.
Applications: (for alignments with tolerances of .00002 in/ft or 0.0017 mm/m or higher)
•
Roll parallelism in paper mills, printing presses
and film lines
•
Leveling almost any surface (squares, frames,
ways, flanges, circles, etc.
•
Roll forming machines
•
High-precision, laser and water-jet cutting
machines
•
Measuring surfaces up to 200 ft. (61 m) long with
one setup
•
Checking plumb of a vertical surface up to 100
ft. (30.5 m)
•
Checking way twist and parallelism between
surfaces
•
Circuit board drilling machines
Measuring and aligning:
•
The flatness and straightness of almost any surface
(squares, frames, ways, flanges, circles, etc.)
•
The flatness and straightness of horizontally
and vertically traversing axes
•
The parallelism of vertical or horizontal surfaces,
even if those surfaces are 100 ft. (30.5 m) apart
•
The squareness of any 2 surfaces
•
The flatness and straightness of vertical
surfaces

operational range of 100 ft. (33 m) in radius.
•
Laser planes flat to 0.5 arc seconds in 180º sweep
