TRANSFER-LINE WING BASES
The L-743 Ultra-Precision Triple Scan® Laser is the ideal instrument
to quickly and accurately calibrate the geometry of almost all machining
centers. It is also very useful for setting the wing bases on transfer
lines perpendicular to the line's centerline. It can also be used to set
the elevation of the bases and to make the "ends" parallel to
the centerline.
The L-743 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. 200' Range for Flatness and Straightness
The L-723 has a range of 100' (30.5 meters) in radius for measuring the
flatness and straightness of transfer line wing bases. This means most
transfer lines wing bases can be aligned with one or, at most, two setups.
In fact, if the laser is placed in the center of the transfer line it
has a range of 200 feet. Another nice feature of the L-723 is the ability
to check flatness and straightness at the same time with one setup. And
since the laser automatically rotates, multiple targets can be used from
the same laser source, which means more than 1 wing base can be aligned
at the same time.
Wireless Targets and Readout Speeds Set-up
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.
Continuously Sweeping Lasers and Live Data Reduces Downtime
Continuously sweeping lasers and live data output create a powerful combination
to align machining centers up to 70% faster than traditional or interferometer
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 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.
Squareness Built Into Laser Head
One
of the L-743's greatest features is its built-in squareness (each plane
is square to each other with an accuracy of up to 1 arc second - 0.00006"/ft or 0.005
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 of not just one axis, but all axes can be measured, usually
with one setup! Where an interferometer may take hours just to set up
a squareness check, the L-743 takes 15 minutes. And, unlike a cylindrical
square, the L-743 can check the entire length of a machine's axis, up
to 100 feet (30.5 meters), not just 12" (305 mm) or 24" (610
mm) of it.
Simultaneously Measure 3 Axes with One Setup
Another great time saver is the L-743's ability to measure the three main
axes of a machine at the same time. 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.
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
(0.00001555"/ft or 0.00125 mm/M) in 90º sweep. The laser planes
are square to each other with an accuracy of up to 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.
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.
