Hamar Laser Instruments’ L-703B Self-Centering Bore Alignment System is an upgraded system that uses the variant of Hamar Laser’s compact and versatile L-703 Laser. The company says this system makes bore alignment easier and up to 75% faster than competing systems. It replaces the L-705 Laser for applications where the laser is mounted externally.
The system is smaller and lighter than the L-705, and works with Hamar Laser’s self-centering targets that require only one measurement per bore. Applications include engine blocks, compressor bores, cylinder bores, shaft bearing bores, stern tubes and more.
“In addition to the new bore laser, our L-703B Self-Centering Bore Alignment System includes our new L-112 Laser Mounting Stand and L-103 Optical Beam Translator,” says Rod Hamar, president of Hamar Laser Instruments. “The new laser and accessories facilitate alignments in smaller spaces, speed setups and have allowed us to significantly reduce the package pricing.”
In addition to being faster and more affordable, Hamar Laser’s new L-703B Self-Centering Bore Alignment System offers a resolution of .00004". (0.001 mm) and much higher accuracy and repeatability than competing products. It is also easier to use and requires less training. It is said a bore alignment survey takes only 15 minutes.
Hamar Laser’s L-703B Self-Centering Bore Alignment System is both smaller and lighter, reducing both the size and weight of the laser significantly. With different accessories and a firmware upgrade, it can be adapted to several other applications, such as extruder alignment, guideway alignment, and lathe and spindle alignment.
It features a built-in rechargeable Lithium-Ion battery with 11 hours of continuous battery life, which replaces the older L-705 Laser’s external battery pack. It has a new laser mounting stand which offers horizontal coarse translation and vertical angular adjustment to greatly speed laser setups. It also has a new optical beam translator which is much smaller than its predecessor, making it easier to fit the L-703B and L-103 into tight spaces.
