The L-740 Ultra-Precision Laser Leveling System offers the fastest, most accurate way of leveling the beds of surface grinders. With wireless targets offering resolutions down to 0.00001" (.00025 mm), automatically sweeping laser planes and high-powered laser alignment software, the L-740 is the ideal alignment tool for high-accuracy machine leveling applications.
Unsurpassed Laser Plane Surface Flatness
The flatness of the laser plane is the most important factor in determining the overall accuracy of the system for surface flatness measurement and our laser planes are the flattest in the world. In a 180º sweep the L-740's laser alignment plane is flat to within 1/2 an arc second (0.00003"/ft or 0.0025mm/M). However, in a 90º sweep, the laser plane becomes even flatter to within 1/4 of an arc second (0.000015"/ft or 0.001 mm/M).
Most Accurate Mechanical Levels Available
The L-740's level vials are accurate to 1 arc second (0.00006"/ft or 0.005 mm/M). Only expensive, time-consuming, difficult-to-use, and fragile electronic levels are more accurate. The combination of accurate leveling, automatically rotating laser planes and wireless targets far outweighs the extra accuracy of electronic levels for surface flatness measurements.
Multiple Targets for Large Applications
You can even use more than one target, which is extremely useful on large machine beds. In fact, up to 4 targets can be used at the same time. This allows the use of multiple work crews, which can really speed alignments
Continuously Sweeping Lasers and Live Data Reduces Downtime
Continuously sweeping lasers and live data output create a powerful combination to align 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 continuously sweeping lasers are far superior to other point-and-shoot laser alignment tools that require time-consuming manual laser rotation and target setup for each point measured.
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 using an interferometer, where the entire length of and axis must be measured before the straightness or surface flatness measurement can be determined and the data provided is not even live.
Laser Planes Have 200' Range
One of the most powerful features of the L-740 is the automatically rotating laser plane with a range of 100 feet (30.5 meters) in radius. That means the surface flatness, straightness or levelness measurement of even the largest machine beds can be checked with one setup.

Targets and Readouts
With Hamar's new 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" (25 mm) measuring range and can be used up to 100 feet (30.5 meters) from the readout. The R-1310-900 or R-1310-2.4 PDA readout utilizes Read9 color software and a wireless receiver to display up to four targets simultaneously. Other features like electronic zeroing and target averaging help to speed setup.
The A-1519-900(2.4) has a resolution of 0.00002" (0.0005 mm) and the A-1520-900(2.4) has a resolution of 0.00001" (0.00025 mm).
Software
Quickly Collects and Analyzes Data
The L-740 can also be linked to our new Plane 5 surface flatness and straightness measurement analyzing software. It is a Windows® XP based software that can quickly analyze almost any layout’s surface flatness or straightness measurement. Plane 5 will even analyze squareness if used with our squareness lasers (L-743, L-742, L-741, L-733, L-732 & L-731).
Squares, rectangles, frames, circles, rings, and up to four sets of ways can all be easily analyzed with Plane5. The laser leveling and alignment data is automatically downloaded by using our wireless data receiver, the A-910-900(2.4).
