L-732 Precision Dual Scan® Laser

Hamar Laser’s L-732 Precision Dual Scan® Laser Alignment System is designed for quickly and accurately aligning all types of machinery with rolls, such as roll-forming machines, film lines and printing presses, as well as several other similar applications, where the required accuracy is a lot lower than that of our L-742 Ultra-Precision Laser. The L-732 can be configured by the factory to have either 2 vertical laser planes (the typical configuration for roll alignment), or 1 horizontal and 1 vertical laser plane (for measuring flatness, straightness and squareness of surfaces and lower-accuracy machine axes). This creates a powerful tool that not only measures alignment, but also re-aligns machinery in a fraction of the time needed with conventional methods.

System Highlights

  • Fast: Aligns roll-forming machinery and other roll alignment applications up to 70% faster than traditional methods.
  • Easy: Multiple high-resolution wireless targets with a range of up to 100 ft provide live alignment data, so alignment errors can be fixed without changing the setup.
  • Accurate: Precision laser planes have a flatness of 2 arc seconds (.00012 in/ft or 0.01 mm/m) in a 180º/360º sweep and 1 arc second (.00006 in/ft or 0.005 mm/m) in a 90º sweep.
  • Versatile: Depending on the laser plane configuration, the system is ideal for virtually all roll machinery; plus machining centers, gantries, roll forming machines and many other applications.
  • Smart: Powerful Windows-based alignment software, combined with advanced wireless interfaces, makes collecting and analyzing alignment data fast and easy.

Key Features

  • 2 continuously rotating laser planes with operational range of 100 ft (30.5 meters) in radius with 2 configurations:
  • 2 vertical laser planes, typically used in roll alignment; and
  • 1 vertical and 1 horizontal laser plane, typically used for machine-tool axis (or surface) flatness, straightness and squareness.
  • Backlit levels accurate to 3 arc seconds (.00018 in/ft or 0.015mm/m). Upgrade to Split-Prism level vials for accuracy to .00006 in/ft (0.005 mm/m).
  • Laser planes flat to 2 arc seconds (.00012 in/ft or 0.01 mm/m) in 180º/360º sweep and 1 arc second (.00006 in/ft or 0.005 mm/m) in 90º sweep.
  • Planes are square to each other up to 2 arc seconds (.00012 in/ft or 0.01 mm/m).
  • Standard targets: A-1519-2.4ZB Single-Axis Wireless Targets with 1 in. (25.4 mm) Measuring Range and .00002 in. (0.0005 mm) Resolution.
  • Optional high-accuracy targets: A-1520-2.4ZB Single-Axis Wireless Targets with .39 in. (10 mm) Measuring Range and .00001 in. (0.00025mm) Resolution.
  • For roll alignment system configuration, factory-built benchmark fixtures and laser translation slide are included in system.
  • Includes Pitch/Roll/Yaw base with coarse adjustments.
  • Battery or AC powered.
  • Typical setup time is 15 minutes or less.

L-732 Precision Dual Scan® Laser Alignment System

Primarily designed for roll alignment and other similar alignment applications that do not require the exacting tolerances of the L-742 Ultra-Precsion Laser, the L-732 Precision Dual Scan® Laser System offers 2 automatically rotating laser planes that can be configured by the factory to have either 2 vertical planes, or 1 horizontal and 1 vertical laser plane. Affordable, yet powerful, the L-732 not only MEASURES but it also FIXES alignment errors in a fraction of the time needed with conventional methods.

2 Arc Second Accuracy

One of the critical components of any laser system is the straightness or flatness of the laser beam or plane, as this is the reference from which the measurements are made.

The L-732’s laser planes are flat and square to  0.00012 in/ft. (0.01 mm/m or 2 arc seconds). It comes with a pitch, roll and yaw adjustment base, for setting the laser planes parallel to reference points, 2-arc-second level vials and a powerful magnet for maximum stability.

Two Configurations for Many Different Applications

With two continuously sweeping, ultra-flat, orthogonal laser planes, the L-732 Dual Scan® Laser System is ideally suited for a whole host of alignment applications. The L-732 comes in 2 configurations. The standard L-732 has 1 horizontal laser plane and 1 vertical laser plane. It is used for measuring flatness straightness and squareness on machining centers, gantries and roll forming machines.

The L-732WW has 2 vertical laser planes and is used primarily for aligning the horizontal roll parallelism of printing presses, paper mills, films lines and other roll alignment applications.

High Resolution Wireless Targets

Another critical component of flatness or straightness measurements is the resolution laser beam detector. This determines how close the measurements can be made.

The L-732 system uses our line of wireless targets (A-1519-2.4ZB and A-1520-2.4ZB) that feature up to 0.00002 in. (0.0005 mm) resolution, large measuring ranges of up to 1 in. (25 mm) and 2.4 GHz “Zigbee” radio wireless communication with our R-1357-2.4ZB PDA Readout, which can simultaneously display up to 5 targets.

These lightweight targets are all powered by rechargeable batteries and can be used as digital height gages when used with precision inserts. And like all Hamar Laser systems, the targets provide real-time alignment data so misalignment errors can be fixed without changing the setup!

Alignment Applications

For alignments with tolerances of 0.00015 in/ft or (0.01 mm/m) or greater, the L-732 can quickly measure and correct machine geometry with minimal setup in the following applications:

  • Water-jet cutting machines
  • Laser-cutting machine
  • Normal or blown-film lines (roll alignment)
  • Rubber (roll alignment)
  • Steel (roll alignment)
  • Textiles (roll alignment)
  • Saw Mills
  • Leveling almost any surface (squares, frames, ways, flanges, circles, etc.)
  • Measuring and aligning:
    • The flatness of almost any vertical surface (squares, frames, ways, flanges, circles, etc.)
    • The squareness of any 2 vertical surfaces
    • The flatness and straightness of vertical surfaces
    • The straightness of horizontally and vertically traversing axes
    • The parallelism of vertical or horizontal 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 vertical surfaces
