What is a Compound Move and When do I use it to Benefit the Alignment Process?

September 29, 2015

A “Compound Move” is when an aligner performs both a vertical correction by shimming and a horizontal correction by moving a MTBM (movable machine) simultaneously. Traditionally, during the alignment process, after a rough alignment is made, the aligner will shim the movable machine until it is within the vertical alignment tolerance. Once within vertical tolerance, […]

September 15, 2015

If the machine to be moved has 6, 8 or more anchor bolts, caution needs to be applied when deciding how to shim the middle machine feet. A method still used by many is to calculate the shimming for the inboard and outboard feet of the MTBM and shim accordingly. Then, use a feeler gauge […]

Shaft Alignment: Setup Basics

December 9, 2014

You’ve always heard the adage, “Laser on the Stationary and Receiver (or Prism) on the Movable.”  In this day and age, however, this “truism” has become obsolete. You see, the concept of the “stationary” machine, per se, is obsolete. ALL machines CAN be moved if they really need to be (no machine grew out of […]

Aligning a Gearbox Shaft to Compressor Bores During Assembly with ROTALIGN ULTRA

August 14, 2014

Some weeks ago, a compressor manufacturer contracted us to perform ROTALIGN ULTRA laser alignment training at their testing facility. During the training, the millwrights mentioned that they had a need to align the gearbox shaft to the compressor bores during the assembly process, before the compressor shaft was installed. Since my ROTALIGN ULTRA also features the CENTRALIGN […]
