Hamar Laser’s L-743 Ultra-Precision Triple Scan® Laser Alignment System is the most accurate and versatile alignment tool on the market today. This powerful yet easy-to-use system is ideal for quickly and accurately checking and fixing the geometry of almost all machining centers and excels at many other demanding applications. Our Ultra-Precision Series L-743 and Precision Series L-733 are the only alignment systems in the world to offer three automatically rotating laser planes with the extreme high accuracy needed for today’s ever-tightening tolerances. This creates a powerful tool that not only measures surface flatness, squareness and straightness, but fixes complex alignment problems in a fraction of the time needed with conventional methods.
If you do not see your application listed, please contact us to discuss your requirements. We will be more than happy to provide a solution that’s right for your unique alignment problem.
The L-743 Triple Scan® Laser Alignment System is one of only 2 lasers (the other is the L-733) in the world to offer 3 automatically rotating laser planes that are accurate enough for today’s ever-increasing tolerances. This creates not only a powerful measurement tool for surface flatness, squareness and straightness MEASUREMENTS, but also a tool that FIXES alignment problems in a fraction of the time needed with conventional methods.
One of the critical components of any laser alignment 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-743 features the flattest laser plane in the world that is flat to 1/2 an arc second (0.00003 in/ft or 0.0025 mm/m) in a 360º sweep and 1/4 arc sec in a 90º sweep (0.000015 in/ft or 0.001 mm/m).
The 3 laser planes are squarewith an accuracy of up to 1 arc second (0.00006 in/ft or 0.005 mm /m). This squareness can be projected out 100 feet (30.5 M), allowing squareness and straightness measurement of even the tallest machine in the world to be easily checked. The L-743 also features 2 built-in level vials that are accurate to 1 arc second.
Another critical component of laser alignment machines is the resolution of the targets. This determines how close the straightness or flatness measurements can be made.
The L-743 system uses our line of wireless targets (A-1519-2.4ZB and A-1520-2.4ZB) that feature up to 0.00001 in. (0.00025 mm) resolution, large measuring ranges of up to 1 in. (25 mm) and a 2.4 GHz “Zigbee” radio communication with our R-1356.24ZB PDA Readout, which can simultaneously display up to 5 targets.
These targets are all powered by rechargeable batteries, are lightweight and can be used as digital height gages when used with precision inserts. And like all Hamar Laser alignment systems, the targets provide live alignment data so misalignment errors can be fixed without changing the setup!
The L-743 Triple Scan Laser Alignment Tool usually allows you to check the entire machine with one setup, before you begin an alignment. This quick analysis, where every part of the machine is checked to the same coordinate system, assures that stack up errors are reduced and all alignment problems are quickly identified.
For applications with tolerances of 0.00002 in/ft or 0.0017 mm/m or higher, the L-743 can quickly measure and correct alignment errors with minimal setup for the following applications
For wireless recording and analyzing alignment data, our color, 3-D flatness and squareness analysis software, Plane5, simplifies and streamlines the data analysis process. It can measure up to 7 different surfaces in one project setup file and present a color, 3-D graph of the flatness and squareness analysis for each surface.
Our Machine Tool Geometry Software is also very useful for measuring and analyzing straightness measurements and squareness of each line of motion of a machining center, gantry or boring mill. The user can select the type of machine tool to be analyzed and the software displays the top, side and front views of the machine. After collecting the data, the report shows flatness, straightness, parallelism and squareness errors on an easy-to-read report.
