Hamar Laser has developed the world's first self-centering bore alignment target that uses no moving parts. It takes just seconds to position the target in the bore for an accurate bore straightness measurement down to .0002 (.005 mm)". Whether checking for bore alignment or straightness, the L-705 Bore Laser dramatically simplifies the process.

Patented Self-Centering Target Vastly Simplifies Setup
Hamar Laser has developed the world's first self-centering bore alignment target that uses no moving parts. It takes just seconds to position the target in the bore for an accurate bore straightness measurement down to .0002 (.005 mm)". Whether checking for bore alignment or straightness, the L-705 Bore Laser dramatically simplifies the process.
Superior Design Reduces Fixturing Costs
The L-705 Bore Laser has been designed with a standard aerospace tooling diameter of 2.250" (57.15 mm). Since the laser beam is concentric to the alignment tool’s OD to within .0005" (.03 mm), a simple flat face and .750" (19.05 mm) hole on center is all that is needed to hold the laser (powerful magnets hold the laser flush to the face). In fact, the laser replaces the first reference target that a typical borescope would need. Hamar Laser has even designed a procedure called NORMIN to eliminate mounting and centering errors of the fixtures.
Long Range and High Accuracy
The L-705 Bore Alignment Laser has a range of 100 feet, and under good environmental conditions, it is accurate to .001" (.025 mm) over the whole range. By carefully following the NORMIN procedure, accuracies of .0002" (.005 mm) in 10 feet (3 M) can also be achieved.
Bore Straightness Measurements in 10 Minutes
With simplified fixturing and self-centering targets, the L-705 Bore Laser can be setup in as little as 5 minutes. And in most cases, bore centerline straightness measurement data can be taken and analyzed in 10 minutes or less using our Read 8 software.
System Handles Large Range of Bores
Any bore, from 1.5" (38.1 mm) to 39" (1 M) or more, can easily be measured, using the A-510 2-Axis Bore Target is used with several self-centering bore adapters (A-510STA, A-510MTA, A-510LTA) to quickly measure bore straightness.
For applications where multiple bores centerlines need to be measured at the same time, the T-218 Two-Axis Universal Target is used, as it has a prism that flips out of the beam path allow the laser beam to pass through to the next target. This is especially useful for alignment of multiple bores centerlines over long distances, such as steam/gas turbine alignment, stern tube alignment and shaft bearing bore alignment. The T-218 can also be inserted into the support bearing of a Climax Portable Boring bar and used with a special flange to easily align the spherical bearings to the target bore centerline.
