In many cases, manufacturing and quality control must co-exist in workcells or in close proximity to one another. For certain machine tools, the permissible amplitudes of foundation vibrations in a manufacturing environment are very low. It often is very difficult to decrease or isolate vibration amplitudes by simply pouring a new foundation on soil. It also may not be possible to increase the stiffness (rigidity) of the machine support structure (floor) itself to avoid resonance or amplification of vibration. In these cases, unacceptable vibration amplitudes can be significantly reduced by using vibration isolators.
Fabreeka isolation materials and machine mounts provide vibration isolation and leveling for proper machine tool installation.
In certain applications, it is not desirable or feasible to mount a machine directly on vibration isolators.
Installing vibration isolators on a machine whose frame/bed requires a stiff connection can cause bending, relative displacement (sag) and other problems, even when the floor is sufficiently rigid. In this case, the frame/bed is attached to a properly designed concrete foundation, which is then supported on the appropriate isolators for the application.
Certain types of machine tools are not inherently rigid and therefore need a rigid support to maintain their prescribed accuracy. In other types of machinery (such as printing presses) consisting of articulated components, a rigid support may be needed to maintain the proper alignment of working parts.
Designing foundations supporting machine tools requires sound engineering procedures for a reliable result. An incorrectly designed foundation is extremely difficult to correct once installed. Engineering disciplines involved in the proper design procedures for isolated support foundations include theory of vibrations, geotechnical engineering (soil characteristics) and structural design/analysis.
