By on December 24, 2015

Rim & Face, Angle & Offset, Parallel & Angular Deviation, Parallel Offset, thousands of inch and mils! What does it all mean? Actually it’s pretty much the same thing, though not exactly. I’ve been a VibrAlign Technical Trainer since 2008 with training classes in a variety of industries and with students previously using other methods […]

Common Precision Shaft Alignment Questions Asked In Our Training Classes

| | | |

By on December 10, 2015

While training mechanics all around the US, I have noticed that many of the questions asked in class are the same regardless of the industry. Fixturlaser tools are very intuitive and easy to use, so this puts the mystery on the alignment process. So here are some answers to some common alignment process related questions […]

Repeatability vs. Desired Outcome in Shaft Alignment, Part 2

| | | |

By on December 2, 2015

In my last post, we looked some reasons for non repeatable, or when “two plus two doesn’t equal four”. This time, let’s think about when we don’t get an expected or desired outcome when we shim and move. Think of it as when “two minus two doesn’t equal zero.” You may perform an alignment measurement, […]

Proper Installation is Essential to Equipment Reliability

| | |

By on November 24, 2015

Performing precision shaft alignment correctly the first time is crucial to the longevity of your equipment and your long term cost savings. New installations suffer greatly from infant mortality rates if the proper installation procedures are not followed. Most common causes are lack of follow up on the essentials, such as proper foundation work, elevations, […]

IT’S ALL ABOUT THE BASE, PART 2

| | |

By on November 4, 2015

One of the biggest problems facing maintenance personnel in the shaft alignment business is the quality of the equipment base. Poor mounting base or platform construction will almost always result in machine movement. If the moveable machine (or the stationary) is not mounted to a solid platform capable of withstanding the weight of the equipment […]

By on October 28, 2015

From the editor – The VibrAlign Trainers see many different machinery base designs and installations during the OJT portion of our training classes across America. Some bases are quite substantial while others are flimsy and actually downright horrible  Poor bases have a negative impact on rotating machinery reliability and can certainly be a cause of […]

Repeatability vs. Desired Outcome in Precision Shaft Alignment, Part 1

| | | |

By on October 14, 2015

When mechanics align rotating machinery, they expect two outcomes. One, they expect their alignment values to be repeatable. Two, they expect shimming and moving machinery to produce a desired outcome-namely, to be in tolerance. In this paper, we’ll discuss repeatability, which is, performing the same measurement twice, and getting the same results. If alignment results […]

By on October 8, 2015

I’m not referring to what happens after you have had too many adult beverages at your favorite watering hole! I’m referring to the bars that holds your rim dial indicator(s) when performing a precision shaft alignment. Bar sag also called rod sag needs to be compensated for, should it occur, otherwise you are introducing a […]

By on September 29, 2015

Sometimes simple procedures can become huge pain points, especially when the necessary knowledge is not known or available. This has proven to be true with the geometric flatness “buck in” procedure involving a sweep laser transmitter and receiver (detector). First, let me begin by defining “buck in”, this phrase is utilized to describe the process […]

Proper Coupling Application, Installation and Maintenance

| |

By on September 16, 2015

Precision maintenance personnel ensure that rotating machinery is aligned well beyond excellent shaft alignment tolerances, but overlook other crucial elements that affect the operation of the machines. One of these elements is the coupling. The coupling is where the “handshake” between the driver and driven machine takes place. The coupling assures consistent power transfer and […]

By on September 10, 2015

Precision shaft alignment of general industrial equipment, such as pumps and compressors, requires precision. But alignment of machine tool spindles and components requires an even greater level of accuracy. Precision alignment of machine tool spindles can improve product quality & finish, reduce scrap, re-work, broken tooling, and improve cutting tool life. There are numerous configurations […]

By on September 3, 2015

In my nearly 38 years of industrial maintenance, I have had the opportunity to work on high speed precision machinery. Most often this is highly automated equipment with photo eyes that determine which function needs to occur for the next sequence. After a few instances of frustration, I found that most often when a particular […]
