Highest Bore Alignment Accuracy in Industry
Hamar’s bore alignment systems are the most accurate in the industry. Our patented, self-centering targets combined with ultra-precise lasers means accuracies down to .0003 in. (0.0075 mm) in 10 feet (1 m) are no problem for our line of bore alignment lasers.
Patented, Self-Centering Target Bore Adapters
Hamar Laser has developed the world’s first self-centering targets (A-510, A-512, T-220, T-221, T-1240) and bore adapters (A-510STA/A-510LTA, A-512STA/A-512LTA, A-514A/B/C, T-221STA) that use no moving parts to self center in a bore. It takes just seconds to position the target in the barrel for an accurate measurement down to .0005 in. (0.01 mm). This eliminates the annoying 0 and 180 measurements needed for typical bore targets.
Widest Range of Bore Diameters in Industry
We’ve been making bore alignment systems for 30 years and have the widest array of targets to check bore alignments with diameters from 1.2 in. (30 mm) to 40 in. (1 m). Most of our targets are self-centering and highly accurate with accuracy down to .0002 in. (0.005 mm) in 10 ft. (3 m).
Simple Fixturing for Fast Setup
The L-705 Laser has been designed with a .750 in. (19 mm) mounting stud and flat face with magnets to hold it flush to fixturing. Since the laser beam is concentric to the OD to within .0005 in. (0.01 mm), a simple flat face and .750 in. (19 mm) hole on center is all that is needed to hold the laser (the extruder package includes a self-centering chuck fixture). In fact, the laser replaces the first reference target that a typical borescope would need.
Wide Angular Adjustment Range
The L-705 Laser has an angular adjustment range of L-705: ±0.18° (± .0375 in./ft or ± 3.13 mm/m) and is used on applications under 40 feet (12 m), such as extruder barrels and hinge-line bore alignments.
TheA-510STA/A-512STA (or LTA) Bore Adapters can be placed on the A-510 Target in two ways:
- Self-Centering Mode, where it will center itself into the barrel.
- Measuring Mode, where the adapter will measure diameter changes in the bore.
To measure diameter changes, a measurement is taken with an inside micrometer of a reference bore. The target and adapter in Measuring Mode are inserted into the reference bore. A measurement is taken with the target in the NORMal position and in the INverted position. The 2 readings are averaged and the result is the starting measurement for the laser. Then at each measuring location, 2 sets of readings, NORMal and INverted, are taken and averaged. Subtract the result from the reference measurement and the diameter change is produced. Get Bore9 Software and it will record the data and do the math for you!
