Bolt Bound? No Alternate Move Calculator? No Problem!

Previous blogs have discussed several different solutions for solving Base Bound & Bolt Bound conditions when preforming precision laser shaft alignment (Base/Bound Math and Solving Base/Bound Alignment Alignment Problems). Sometimes though, the solution for a Bolt Bound issue is fairly [...] Read More

Aligning Machines Mounted on Chocks

“Our large machines use adjustable chocks, instead of shims for correcting the vertical alignment; can we use the VibrAlign Verti-Zontal compound move with our Fixturlaser XA when correcting the misalignment?” Absolutely! Adjustable chocks are typically found on large machines such [...] Read More

Jacking Bolts

Jacking bolts provide a smoother, easier way of moving machinery than using pry bars and hammers. Their use will almost always speed up the shaft alignment process, prevent excessive minor moves back and forth, and generally make the task of [...] Read More

Cooling Tower Adventures

The OJT portion of a recent XA alignment training class led us to a two-cell cooling tower that had a run of bad luck–motor bearing failures, internal supports broken, visibly shook when it ran, etc.
