Laser Cutting and Water Jet Machines

laser alignment of Laser Cutting and Water Jet Machines WATER-JET AND LASER-CUTTING MACHINE ALIGNMENT

The L-732 Dual Scan® Precision Machine Tool Alignment Laser is the one of only 2 lasers in the world (the L-742 is the other) to offer 2 automatically rotating laser planes that are accurate enough for today's ever-tightening tolerances. This creates a powerful tool that not only measures, but also fixes geometry problems on almost any kind of laser-cutting or water-jet machine, all in a fraction of the time needed with conventional methods.

Align Machines up to 70% Faster

Traditional methods of alignment include levels, squares, straight edges and indicators and require numerous setups and a lot of time. In fact, this is precisely why a lot of companies these days have severely cut back on their machine calibrations.

Conversely, automatically rotating lasers and live data output create a powerful combination to align laser cutting and water-jet machines up to 70% faster than traditional or interferometer methods. Downed machines will be up and running, producing quality parts in record time. HLI's automatically rotating lasers are also far superior to other point-and-shoot laser systems that require time-consuming manual laser rotation and target setup for each point measured. They also allow the use of multiple targets, which is especially helpful for large machine tools.

Live Alignment Data

By providing live alignment data, misalignment errors can quickly and easily be fixed without having to change the setup. This is a tremendous benefit, especially if you are used to using an interferometer, where the entire length of and axis must be measured before the straightness or flatness can be determined and the data provided is NOT even live.

Check Entire Machine Squareness in Record Time

One of the L-732's greatest features is its built-in squareness (each plane is square to each other up to 2 arc seconds or .00012"/ft or .01 mm/M). If you have ever tried to set up a cylindrical square or interferometer to check squareness, you will be amazed at how quickly and easily the squareness can be measured, usually with one setup! Where an interferometer may take hours just to set up a squareness check, the L-732 takes 10 minutes. And, unlike a cylindrical square, the L-732 can check the entire length of a machine's axis (up to 100' or 30.5 M), not just 12" or 24" (305 mm or 610 mm) of it.

Wireless Targets and Readout Speeds Set-up

With Hamar's new line of wireless targets (A-1519-2.4ZB and A-1520-2.4ZB), there is no need to string long extension cords to reference targets. The targets have up to a 1" measuring range, a resolution as low as 0.00001" (0.00025 mm) and can be used up to 100 feet (30.5 meters) from the readout. The R-1355-2.4ZB Readout uses color software and a wireless receiver to display up to 5 targets simultaneously. Other features like electronic zeroing and target averaging help to speed setup.

Significantly Reduce Part Set-up Time

Another benefit of having a properly aligned machine tool is that part setup time is significantly reduced. An article in the October 1998 issue of Quality in Manufacturing Magazine Jim Abitz, tool and die maker, describes the benefit of laser alignment to the John Deere Corporation:

"..[laser alignment] makes the operators a lot happier because they don't have to struggle for two or three shifts to get a machine to work properly."

Simultaneously Measure 2 Axes with One Setup

Another great time saver is the L-732's ability to measure the 2 main axes of a laser cutting or water-jet machine at the same time with the same setup. Not only can you measure the flatness and straightness of each axis, but you can also measure the squareness of the three axes and also the parallelism of additional axes, like an extending quill or rotary axis.

Software Quickly Collects and Analyzes Data

Hamar's new line of alignment software, combined with newly designed computer interfaces, makes collecting and analyzing machining center alignment data faster and easier than ever before. All of the software is Windows based and provides large, color graphics. Alignment reports clearly and concisely show the machine's condition. In today's world of ISO 9000 documentation hell, our software will help you submit alignment reports in record time. Software Quickly Collects and Analyzes Data
