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.

Machine Tools – Lower Accuracy
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.
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.
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.
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!
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:
