Fabrications Alignment Applications

Maintaining precision alignments in fabrication plants has never been easy. Typical methods include optical telescopes and theodolites. These methods are very time consuming, require a lot of manpower and are susceptible to significant errors.

Our lasers offer the precision and timesavings to meet the ever-tightening tolerances of the fabrications industry. Our L-733 Precision Triple Scan® Alignment System is one of only 2 lasers in the world (L-743 is the other) to offer 3 automatically rotating laser planes, which creates a powerful tool to not only MEASURE but also FIX almost any misalignment problem in fabrications and the machines that make them.

Less Manpower Needed for Alignments

The L-733 reduces alignment manpower by using wireless targets and automatically rotating laser planes to make setting up the laser a one-man job. This frees up technicians for other critical work. Compared with optics that require at least 2 technicians for each measurement point, the L-733 can save a lot of time an manpower and thus improve productivity. In fact, once the laser has been setup, there is no need to have a technician operate the laser during the alignment. This means that the traditional 2-man optical crew can both "turn bolts", and thus significantly reduce the time required for alignments.

Laser Technology Reduces Optics' Variability Between Alignment Crews

PSDs, or position sensing detectors, are one of the critical components of our laser alignment systems. It is this PSD that senses the laser beam and turns it into a digital signal. This greatly reduces the man-to-man variability found in optical measurements because sophisticated electronics determine the measurement rather than the human eye.

Anyone with optical experience knows that the quality of the measurement depends on having the same experienced person perform the entire alignment, which can create big problems when the job takes more than one shift to complete. By relying on the PSD to produce highly repeatable measurements, our L-733 makes it much easier to hand off an alignment project from one crew to the next. This greatly increased accuracy and reduces the need to have new crews backshoot the previous crews' work to "calibrate" to their readings.

Easy Squareness and Plumb Measurements

The L-733 has 3 automatically sweeping laser planes, one horizontal and 2 vertical, which are all square to each other to up to 2 arc seconds (0.00012"/ft or 0.01 mm/M). This means that complex tasks like checking the squareness of machine tool axes or fabrication surfaces are now easier than ever. The L-733 can also be used to easily check the plumbness vertical surfaces as large as 100 feet long (30.5 meters) and 100 feet high, as the vertical laser planes have an operation range of 100 feet (30.5 meters) in radius and are plumb when the laser is leveled.

No Need for Optics' Recalibration After Plumb Measurements

Unlike some optics that usually require time-consuming recalibration of the levels each time plumb is checked, the L-733 can simultaneously check level and plumb from a single setup. This is because the squareness measuring capability is built into the instrument, so once the laser is level, both vertical laser planes are plumb. Furthermore, the levels usually only require calibration once a month, not every time you use it!

Multiple Targets and Laser Planes Reduces Downtime

With multiple laser planes and multiple targets, the L-733 can take the place of at least 2 sets of optics. Once the laser is setup, multiple technicians can each use a target to realign the machining centers or the fabrications they make. This can save tremendous amounts of time.

Laser Planes Have 200' Range

One of the most powerful features of the L-733 is the automatically rotating laser plane with a range of 100 feet (30.5 meters) in radius. That means the straightness, flatness and squareness of 100-foot-high vertical or 200-foot-long horizontal surfaces can easily be measured without having to move the laser.

Competitive Laser Systems Use 10-Year Old Technology

Our competitors' alignment lasers use point-and-shoot laser technology, along with remote beam-bending devices that are difficult to set up and re-locate. We abandoned that laser technology 10 years ago with the introduction of our multi-plane, continuously rotating lasers. Not only is this point-and-shoot technology difficult to set up, it also requires extra manpower and about 50% to 70% more time.

Wireless Targets and Readouts

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. These 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 a Nomad PDA, color software and a wireless receiver to display up to 5 targets simultaneously.

Software Quickly Collects and Analyzes Data

The L-733 can also be linked to our new Plane 5 flatness analyzing software. It is a Windows 95/98 based software that can quickly analyze almost any layout for flatness or straightness. Plane 5 will even analyze squareness if used with our squareness lasers (L-743, L-742, L-741, L-733 & L-732). Squares, rectangles, frames, circles, rings, and up to four sets of ways can all be easily analyzed with Plane5. The alignment data is automatically downloaded by using our wireless data receiver, the A-910-2.4ZB.
