Flatness and straightness measurements of almost any surface (squares, frames, ways, flanges, circles, etc.)
Measuring and leveling machine beds and ways, large bearing surfaces, and fabrications
Surface plate flatness calibration
Checking the parallelism of horizontal or vertical surfaces or machine lines of motion.
Unsurpassed Plane Flatness
One of the critical components of any laser leveling and alignment system is the straightness or flatness of the laser beam or plane, as this is the reference from which the measurements are made. The L-740's continuously rotating laser plane is flat to 1/2 an arc second (0.00003"/ft or 0.0025 mm/M) in a 360º sweep and 1/4 arc sec in a 90º sweep (0.000015"/ft or 0.001 mm/M).
New Line of Wireless Targets
Another critical component of flatness or straightness measurements is the resolution laser beam detector. This determines how close the measurements can be made.
The L-740 system uses our line of wireless targets (A-1519-2.4ZB and A-1520-2.4ZB) that feature up to 0.00002" (0.0005 mm) resolution, large measuring ranges of up to 1" (25 mm) and 2.4 GHz "Zigbee" radio wireless communication with our R-1355-2.4ZB PDA Readout, which can simultaneously display up to 5 targets.
These lightweight targets are all powered by rechargeable batteries and can be used as digital height gages when used with precision inserts. And like all Hamar Laser systems, the targets provide live alignment data so misalignment errors can be fixed without changing the setup!
