Bore Alignment Applications
Self-Centering Target Adapters
Reduces Alignment Time by 70%
Hamar Laser has been making bore alignment lasers for over 40 years. We know bore alignment. Our systems are known for their high accuracy, repeatability, innovative design and fast setup.
Our patented, self-centering, bore alignment targets are the easiest and fastest way to check bore alignment. This means no "bore sweeps" or no "0°-180° reversals" to correct alignment errors due to diameter changes. This reduces measurement points by at least 50%. It also reduces alignment times by 70% because it only takes about 5 seconds to take a measurement!
To measure the alignment, simply insert the bore target and self-centering adapter into the bore, let the weighted handle set the target in the bore and immediately the real-time alignment results are displayed on a simple 2-axis readout and then transmitted to our Bore9 Software. In most cases, you can achieve accuracies down to .0002 in. (0.005 mm) in 10 feet (3 m).
There are 6 bore alignment systems to choose from:
