Hamar Laser Instruments has upgraded its self-centering bore alignment system. The new variant, known as the L-703-B self-centering bore alignment system, can be used on engine blocks, compressor bores, cylinder bores, shaft bearing bores, stern tubes and other equipment, the company said.

The L-703B Self-Centering Bore Alignment System makes bore alignment easier and up to 75% faster than competing systems. The new L-703B Laser replaces the L-705 Laser for applications where the laser is mounted externally, the company said.

Smaller and lighter than the L-705, the L-703B works with Hamar Laser’s patented, self-centering targets that require only one measurement per bore. 

“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,” said 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. Rounded out with our patented, self-centering targets, there is no better system than the L-703B for high-accuracy bore alignment.”

In addition to being faster and more affordable, Hamar Laser’s new L-703B Self-Centering Bore Alignment System offers a resolution of .00004 in. (0.001 mm) and much higher accuracy and repeatability than competing products. It is also easier to use and requires less training. A bore alignment survey takes only 15 minutes, the company said.

The new self-centering system includes several upgrades. It is smaller and lighter than its predecessor. It is adaptable to other applications. It has an internal rechargeable battery with 11 hours of battery life. It has an improved laser mounting stand and an optical beam translator that is smaller and easier to use than its predecessor.

The L-703B laser supports Hamar Laser’s entire series of 2-axis cabled bore targets when used with the company’s R-1307 Readouts, and supports Hamar’s R-358 Computer Interface when used with those targets, the company said.

Hamar Laser Instruments designs, manufactures, sells and services a broad range of precision laser alignment and calibration systems. It is based in Danbury, Connecticut, USA.
