AV Mount
To obtain optimum performance from machine tools after installation, the noise levels must be reduced and the external and inherent vibrations kept to a minimum. In order to achieve this, Avmount Anti-Vibration mountings can be used that are not only easy to install but also provide for precise-levelling. The mounts absorb shocks and impacts caused by punching machines and presses as also the horizontal forces from injection moulding machines and shaping machines.
The mounts keep the machinery firmly in position whilst aiding smooth operation. Avmounts eliminate mass movements of shaping machines and prevent them from drifting. Lathes, grinding machines and other precision machines are protected from external shock loads and vibrations.
Applications of Mountings (Type AV)

Benefits of Mountings (Type AV)
No foundation or grouting required
Easy installation
Precision levelling
No external shock loads or vibrations
Absorption of shocks and impacts
Machinery firmly positioned thus preventing wandering
Lower noise levels
Mobility of machinery
Immediate commissioning
Installation Procedure
Lift the machine above the ground.
Screw down the bolts into their respective guides.
Lower the machine so that it rests on the machine mounts.
Level the machine using a precision spirit level.
Tighten the lock nut after levelling, to prevent any alterations in level while in operation.
The adjustable height of our mounting is as follows:
AV-02
33-37 mm
AV-04
?43-55 mm
AV-08?
48-60 mm
AV-12
57-70 mm
AV-20
65-77 mm
Should the levelling exceed this limit because of an uneven floor, then a spacer of appropriate diameter and thickness should be inserted between the machine base and the mount, to compensate for the difference in the floor level at any support point.
In some machines, the design of the base is hollow and the bolt hole provided is such that the mountings cannot be directly fixed to the base. In such cases, the machine is made to rest on an adequate size of flats and the mountings placed under them. The rest of the procedure is the same as discussed.
If the bolt lengths are more, the chamfered end may be cut to suit the machine. After cutting it to the required length, then chamfer the end to an included angle of 120 degrees and a 3 mm depth. This is necessary when machine bases have pockets as illustrated.
In case of light machines running at very high rpm’s, there may be a tendency for the machine to drift a little. In such cases, apply Dunlop’s S 758 rubber adhesive on the floor and on the bottom surface of the rubber mounting and then lower the machine on to the mount. In a few hours the mount will stick to the floor and thus prevent even minute shifting of the machine. This is necessary in case of high frequency generators, bench grinders, power presses, notching machines, etc. / application of rubber adhesive to be done on clear and dry floor (i.e. floor should be clear from oil, coolant dust etc.)
Capacity: 100 kg to 2000 kg per mounting.
