The L-743 Ultra-Precision Triple Scan® Laser is
the ideal instrument to quickly and accurately calibrate the geometry
of almost any kind of press. It is one of only 2 lasers in the world (the
other is the L-733) to offer 3 automatically rotating laser planes that
are accurate enough for today's ever-tightening tolerances. This creates
a powerful tool that not only FINDS, but also FIXES geometry problems,
all in a fraction of the time needed with conventional methods.
The
critical alignment of any press is the parallelism of the upper and lower
rams to each other and squareness to the way (gib). The ways also need
to be parallel. Poor alignment results in poorly formed parts that have
to be scrapped and excess wear and tear on the press itself.
L-700 Spindle Laser Ideal for Punch Presses
For punch presses, critical alignment is punch-to-die
centering. Every time there is tool changeover, the die and punch need
to be aligned for both center and angle. Since punches and dies are changed
frequently, quick alignment becomes a necessity. The L-700 Spindle Alignment
Laser is a great tool for this alignment.
Ram Parallelism Made Simple with Rotating Laser Planes
Simple to use and easy to set up, the L-743 is the ideal instrument to
measure upper-and-lower-ram parallelism. A simple setup procedure positions
the laser plane parallel to the fixed ram. Targets are then repositioned
to the movable ram and parallelism is easily measured. With Hamar Laser's
Plane 5 Software, setup and parallelism measurements are achieved even
faster. And once the laser has been set up, if errors are found, they
can be fixed immediately without having to change the setup.
Complete Way Squareness Measurements in Two Setups
With the L-743's built-in squareness (each laser plane is square to each
other with an accuracy of up to 1 arc second), measuring the perpendicularity of the way
(gibs) to the rams is a simple task. In fact, with just two set-ups you
can measure all four ways (gibs) for squareness in two axes. And since
the data is live, squareness errors can be fixed without changing the
setup. Given that the laser has a range of 100 feet (30.5 meters), the
entire length of even the largest press can easily be measured for squareness.
Significantly Reduce Downtime when Changing Tools
Changing punches and dies is time consuming and realignment is a necessity.
If a ram is out of parallel to the dies, poor part quality and costly
premature punch and die wear can occur. Inadequate alignment also results
in excess wear on the press itself and can even lead to way (gib) damage.
With the high cost of machine overhauls, proper alignment becomes a big
cost saver. The L-700 dramatically speeds the alignment process and provides
a very accurate alignment.
Continuously Sweeping Lasers and Live Data Reduces Downtime
Continuously sweeping lasers and live data output create a powerful combination
to align presses up to 70% faster than traditional methods. Downed machines
will be up and running, producing quality parts in record time. HLI's
continuously sweeping lasers are 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.
By providing live alignment data, misalignment errors can be quickly and
easily fixed without having to change the setup. This is a tremendous
benefit, especially if you are used to using inside micrometers or tram
bars, where the entire length of and axis must be measured before the
straightness or flatness can be determined.
L-743 Significantly Reduces Stack Up Errors
One of the biggest problems with aligning machine tools using conventional
methods is that many different alignment tools must be used, requiring
a lot of time and increasing stack-up errors. Another problem is that
an alignment is only as good as the tools used to perform it. The machinist
level is a good example: it has a resolution of .0005" per foot,
not very accurate for today's ever-tightening tolerances.
The L-743's laser planes, by contrast, have a flatness of 1/2 an arc second
(0.00003"/ft or 0.0025mm/M) in a 180º sweep and 1/4 arc second
(0.000015"/ft or 0.001 mm/M) in 90º sweep. The laser planes
are square to each other to within 1 arc second (0.00006"/ft or 0.005
mm/M). They further have the advantage of creating a single reference
from which to measure machine geometry, significantly reducing stack-up
errors.
Squareness Built Into Laser Head
One of the L-743's greatest feature is its built-in squareness. You will
be amazed at how quickly and easily the squareness of not just one axis,
but multiple axes can be measured, usually with one setup! The L-743 takes
just 10 minutes to setup and, unlike a cylindrical or knee square, the
L-743 can check the entire length of a machine's travel, up to 100 feet
(30.5 meters), not just 12" (305 mm) or 24" (610 mm) of it.
Wireless Targets and Readout Speeds Setup
With
Hamar's line of wireless targets (A-1519-900, A-1519-2.4, A-1520-900 and A-1520-2.4), 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-1310-900 (R-1310-2.4) Readout uses a HP PDA, color software and a wireless
receiver to display up to 4 targets simultaneously. Other features like
electronic zeroing and target averaging help to speed setup and alignment.
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. 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.
