"Surface roughness of objects is typically one of the parameters that are measured during quality control tests. This is because surface roughness has certain implications for the functionality of various objects. When performing surface roughness measurements, vibrations from other machinery can interfere with the readings from surface roughness testers.\n\nUnfortunately, a typical manufacturing plant is likely to have a lot of machinery that create vibrations all around the plant. To mitigate this, machine operators using surface roughness testers are likely to use various approaches to reduce the vibrations.\n\nVibration Control\nIf there is a machine with excessive vibration, one could consider using vibration isolators to ensure that most of the vibration coming from the machine is absorbed. Most vibration isolators are mounted on the equipment and come in a variety of shapes and forms. Here are some of the most common types of isolators:\n\nRubber Vibration Isolators\nRubber is an excellent vibration isolator. The rubber helps prevent unwanted movement of the equipment during operation and can also absorb most of the vibrations. Better still, rubber is easy to work with and can be customized to fit most equipment.\nSpring Vibration Isolators\nSpring vibration isolators work in the same way as they do in the suspension system of an automobile. When fitted on to a machine, the springs capture the vibration and redirect the energy in a different direction. By doing this, the springs help to reduce the amount of vibration that is transmitted to the ground or is absorbed by the machine on which they are mounted.\nOil\nOil is used as a lubricant to help reduce vibration that is caused by moving parts. Machines often have various moving parts, and these add to the vibration that the machine causes. Oil works best alongside other mechanisms for reducing vibrations.\nFoam Vibration Isolators\nFoam works in the same way as rubber in that it can stop unwanted machine movements and reduce vibrations. The downside to using foam is that it breaks up very easily, especially when subjected to constant pressure. For this reason, foam vibration isolators are not widely used. Polyurethane is often considered as an alternative to foam. It is a much more durable material than foam but lacks the flexibility that comes with rubber and foam.\nAir Isolators\nAir vibration isolators operate in the same way as airbags work in an automobile. They are filled with air and mounted on the machinery. The air acts as a cushion, absorbing the excess vibration energy and spreading it outward. Air isolators, however, are known to leak, especially when being operated in vacuum conditions.\nReducing machine vibration comes with a host of other benefits. Apart from making your surface roughness tests more accurate, eliminating or reducing vibrations in your facility can help reduce your cost of repair and maintenance. This is because constant vibration can damage machine and equipment by loosening bolts and nuts on the equipment. If sufficiently strong, it can also crack display screens as well as damage the internal workings of various equipment."
