Laser Alignment, Alignment Lasers or Aligning Lasers – What’s the Difference?

Here at OASIS, we often receive requests for “laser alignment” services. However, this term can apply to several similar, but distinct solutions. In this post, we provide a brief overview of the various tools and technologies that can fall under the category of laser alignment. In future posts, we will delve further into laser alignment […]

Repeatability in Measurement – Why is it Important?

When speaking of measurements, accuracy is the topic that is most often discussed. But in fact, there is something equally important that is often overlooked – repeatability, otherwise known as precision. When measuring in industrial conditions, a service company can take alignment measurements with less than perfect instruments and achieve a specification of accuracy. Yet, […]

Location, Location, Location- Establishing Proper Alignment Foundations

One of the most common tasks involving machinery alignment is locating machine components during installation. The erection process of a large or complex machine can be a daunting task. In some cases, the process involves thousands of components that fit perfectly together on the design engineer’s CAD software, but in reality are subject to real […]

Thermal Growth Studies Help Troubleshoot Issues in Turbo Machinery

Large and small machinery is susceptible to the effects of temperature variations due to fundamental properties of materials at the molecular level.  Basically, when various materials change temperature, they change dimensionally.  When the size of the components affected is considerable, the coefficient of thermal expansion of the material is high, and if there is enough […]

Why Level Machines?

What is level? Level is an imaginary plane level to Earth at any particular tangential point on our planet. Due to Earth’s gravity (which is approximately normal to the curvature of the Earth) the level plane can be measured quite easily by several methods. A very crude but effective way to measure level is by […]

What Is Alignment?

The many uses of the word “alignment” describe a structure between objects, ideas, or people. When mechanics use the word alignment, they generally mean the relationship between one mechanical component and another. In a three dimensional world, that implies that the component relationship is described in a way that leaves no degrees of freedom unaccounted […]
