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 CNC machining centers and milling machines, as well as 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 3 automatically rotating laser planes with the extremely 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 offers 3 automatically rotating laser planes that are the most accurate in the industry. The unique design makes the L-743 able to align many different applications from machining centers to injection molding machines to roll alignment applications and many more. This power laser not only a measures surface flatness, squareness and straightness, but it also 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 since you can’t measure any more accurately than the flatness of the plane. The L-743 features the flattest laser plane in the world that is flat to 1/2 an arc second (.00003 in/ft or 0.0025 mm/m) in a 360º sweep and 1/4 arc sec in a 90º sweep (.000015 in/ft or 0.001 mm/m).
The 3 laser planes are square with an accuracy of up to 1 arc second (.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.
The L-743 system uses our A-1519-2.4ZB/A-1520-2.4ZB Wireless Targets that feature up to .00001 in. (0.00025 mm) resolution, large measuring ranges of up to 1 in. (25 mm) and a 2.4 GHz radio communication, using the Zigbee technology, with our R-1357-2.4ZB 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 real-time 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 boring mill, gantry, machining center or VTL with one setup. Less setups means faster alignments and better results due to less setup errors. This means alignment problems are quickly identified and the machine’s calibration quickly assessed.
For applications with tolerances of .00003 in/ft or 0.0025 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 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.
