Industrial Machinery

 

Designing foundations supporting machine tools requires sound engineering procedures for a reliable result. An incorrectly designed foundation is extremely difficult to correct once installed. Consequently, many engineers use Fabreeka isolation materials and machine mounts, knowing that they provide vibration isolation and leveling for proper machine tool installation.

 

Fabreeka also provides solutions for applications when it is not desirable or feasible to mount a machine directly on vibration isolators. For example, installing vibration isolators on a machine whose frame or bed requires a stiff connection can cause bending, relative displacement or sagging and other problems, even when the floor is sufficiently rigid. For cases like this, Fabreeka recommends that the frame or bed is attached to a properly designed concrete foundation, which is then supported on appropriate isolators for the application.

 

In many cases, manufacturing and quality control must co-exist in work-cells 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 or rigidity of the machine support structure, often floors, itself to avoid resonance or amplification of vibration. In these cases, unacceptable vibration amplitudes can be significantly reduced by using vibration isolators provided by Fabreeka.

 

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. Fabreeka is a trusted partner and supplier in those cases as well.

 

Engineering disciplines involved in the proper design procedures for isolated support foundations include theory of vibrations, geotechnical engineering or studying soil characteristics plus structural design and analysis.

 

Rotating Equipment

 

Fabreeka isolation products provide vibration control on a wide variety of rotating and reciprocating machinery and equipment that produce vibration during operation. Our engineers work closely with OEMs as well as end users to obtain the operating frequencies, dynamic or unbalanced loads, critical alignments and isolation mount specifications for a complete isolation solution.

 

In line with this, fans, blowers, motors, reciprocating and screw type pumps as well as compressors, engine-generator sets, gear boxes and generators are all applications where Fabreeka or Fabcel isolation pads, washers and bushings can be used. They are also the right choice to prevent roof top HVAC vibration.

 

Depending on the rotational speed of the equipment and its weight support area, other Fabreeka products, namely Fabcel pad or machine support foundation isolation products such as FAB-EPM, FAB-EFP and Fabsorb are qualified.

 

Turnkey solutions are also available at Fabreeka, including demolition, foundation design and concrete construction if a foundation is needed for rotating and other equipment.

 

Other Equipment

 

Fabreeka Crane Rail pad material is used to reduce vibration, stresses and mechanical wear and tear associated with bridge, gantry and ore crane operation, thereby reducing maintenance costs. Fabreeka Crane Rail pads are designed to relieve girder stress, improve load distribution, eliminate mechanical wear of flange or cover plates, dampen vibration and reduce noise.

 

The laminated thermoset plastic (LTP) surface of the crane rail pad improves wear resistance, restricts lateral movement and provides a low coefficient of friction support for the rail. Tests performed by independent sources have shown up to 40% reduction in runway beam web stress and noise levels reduced substantially when using this Fabreeka product.

 

Automation equipment such as assembly and packaging equipment can cause vibration affecting other equipment or may be sensitive to vibration coming from the manufacturing floor. Vibration isolation products such as Fabreeka or Fabcel pad plus isolation washers and Fabreeka bushings can be used to reduce the vibration to more acceptable levels, as is also the case with milling machines, CNC and other machine tools that may also be sensitive to factory floor vibration, influencing their accuracy.

 

Last, not least, injection molding machines can cause disturbing vibration to other machines when molds are opening and closing. Depending on the size, pad products supplied by Fabreeka can be placed directly under the machine or support the machine and a foundation to add rigidity.

Precision Manufacturing

 

Precision manufacturing is needed for many different industries such as aerospace, industrial, medical, military, semiconductor and many others. There, the equipment that cuts, turns, polishes and positions with nanotechnology can provide finishes and measurements within microns and even angstroms.

 

To achieve the best results possible with the equipment in every environment, Fabreeka has developed matching isolation and foundation products. Working with and at CNC machines or precision lathes, among many others, can be optimized by incorporating Fabcel pads, Fabcel Lev-L mounts, or Fabcel LeveLers.

 

When it comes to ultra-precision equipment being used in many industries including semiconductor wafer processing, optics and lens manufacturing and non-standard material machining processes, low frequency pneumatic Precision-Aire Leveling isolators (PAL) provide superior low frequency vibration isolation. Customers worldwide rely on Fabreeka PAL isolators, knowing that they meet the critical needs of metrology instruments, electron microscopes, inspection stations and other precision manufacturing equipment.

 

Laboratory

 

Laboratory work is a synonym for precision work where laboratory equipment isolation is a must. Professionals using tabletop microscopes and electron microscopes for biomedical research, semiconductor manufacturing or other tasks want the highest accuracy and the best resolution. To prevent human footfalls and structural vibration from decreasing performance and accuracy of their microscopes, many companies and institutions use PAL low frequency, pneumatic isolation systems which provide attenuation not only in laboratories and clean-rooms but wherever laboratory equipment isolation is on the agenda.

 

Analytical balances and precision scales also need stable work conditions for accurate measuring. Here, Fabreeka offers pneumatic isolation products and active systems for added vibration reduction to rule out that even small oscillations or vibration that can alter weight results go unnoticed by lab personnel. This could be the case when equipment is moved across the laboratory floor, heavy traffic outside affects the building or other activities in other areas of the building create vibration.

 

MRI and NMR become more and more important to study humans and materials. Fabreeka is committed to the science of MRI vibration isolation, working both ways with products that reduce the vibration coming from the environment and also the induced MRI vibration into the building. Thus, Fabreeka has provided customers with vibration isolation solutions for all types of high resolution MRI, NMR and Cryostat equipment ranging in size from 300 MHz to 900 MHz. All pneumatic isolator hardware for NMR applications is made non-magnetic using stainless, aluminum or brass and is designed to interface with the existing magnet support brackets at the desired height. MRI vibration isolation solutions include vibration measurements and the design of the support structures, including structural and dynamic analysis.

 

Metrology

 

Metrology is a fascinating field with steady increases in measuring speed and accuracy of Coordinate Measuring Machines (CMM) and optical equipment. Since vibration is one environmental factor which can compromise a CMM’s accuracy and repeatability, Fabreeka has extensively studied allowable vibration criteria and put a lot of work in developing Vibration Site Survey and Analysis services to help customers determine if they need CMM isolation or not. When it is the case, typically low frequency vibration of less than 50 Hz requires attenuation. Fabreeka pneumatic isolators such as PAL Isolators and PLM Mounts provide significant CMM isolation and for other metrology equipment requiring low frequency vibration control.

 

Along with the standard pneumatic isolation systems that let most CMM function properly, Fabreeka systems can also be custom-made to be integrated into the machine. When larger CMM require foundations, Fabreeka is the number one resource for pneumatic isolators or pad isolators for foundation isolation. Fabreeka can also offer a foundation turnkey solution including project management, demolition, foundation design and construction.
