The L-743 Ultra-Precision Triple Scan® Laser is
the ideal instrument to quickly and accurately calibrate the geometry
of almost any kind of injection molding machine. 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 alignments of any injection-molding machine are platen-to-platen
parallelism and tie-bar squareness. Poor alignment results in premature
wear on the mold, part flashing, and stress on, and potential breakage
of, tie bars. With long lead times and mold costs as much as $250,000
or more, proper alignment becomes critical.
Platen-to-Platen Parallelism Made Simple with Rotating Laser Planes
Simple to use and easy to set up, the L-743 is an ideal instrument to
measure platen-to-platen parallelism. A simple setup procedure positions
the laser plane parallel to the fixed platen. Targets are then repositioned
to the movable platen 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
Tie-Bar Squareness Measurements in 2 Setups
With the L-743's built-in squareness (each laser plane is square to each
other), measuring the perpendicularity of the tie bars to the platens
is a simple task. In fact, with just two setups you can measure all four
tie-bars 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) in radius, even the entire length of
the largest injection molding machines can easily be measured for squareness.
Significantly Reduce Downtime when Changing Molds
Changing a mold is time consuming and realignment is a necessity. If a
mold is slightly out of parallel to the platen, costly flashing and premature
wear can occur. Inadequate alignment also results in excess wear on the
injection-molding machine itself and can even lead to tie-bar breakage.
With each tie bar costing at least $10,000, proper alignment becomes a
big cost saver. The L-743 not only speeds the alignment process significantly,
but also reduces tooling and maintenance costs.
Continuously Sweeping Lasers and Live Data Reduces Downtime
Continuously sweeping lasers and live data output create a powerful combination
to align injection molding machines 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. The targets come with
70-poind magnetic bases for maximum stability, so you can leave them on
adjustment points (even horizontally!) when bringing the machine back
into alignment. This is a tremendous benefit, especially if you use multiple
targets, as you can literally watch the entire platen come back into alignment.
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, are flat to 1/2 an arc second (0.00003"/ft
or 0.0025mm/M) in a 180° sweep and 1/4 arc second (0.000015"/ft
or 0.001 mm/M) in 90° 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.
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.
