cutting-and grinding machines. Machines for the textile and printing industry.
1) Support for a lathe
Given data: - Weight of the lathe: 2200 Kg.
- Minimum speed: 140 rpm.
- Quantity of feet: 4.
Selection: the load on each foot is
2200
4
According to table 1 Part. 702 should be taken.
Mounting instructions
A
) Lift the machine. Position the footplate.
B
) Mount the adjustment bolt with the nut and washer.
C
) By turning
the adjustment bolt further, the support plate will lift until the desidered height has been reached.
D
) Lock the
adjustment bolt with the nut.
1) Supports for a metal press
Given data: - Weight of the press: 3900 Kg.
- Min. number of shocks: 120 strokes/min.

According to table 1 Part. 703 should be taken.
When to use vibration absorbing feet
In case in a machine frequent “vibrations or shocks”
occur, it will be necessary to use vibration absorbing
feet instead of our standard feet.
Because of the natural characteristics of the rubber
elements, the selection of the proper type is very
important. In a certain range of vibrations or shocks
a resonance will occur, in another range of
vibrations the feet will not absorb any vibrations at
all. It is therefore important to follow exactly our
selection procedure.
Selection procedure
1) Calculation of the load on each foot
In the following formula we have considered that
the weight of the machine is divided equally over
the feet:
Weight of the machine (Kg)
Number of feet
2) Selection of the type of vibration absorbing
foot - Table 1
The selection of the type of a vibration absorbing
foot depends on the load on each foot and the
lowest number of revolutions (or number of
shocks)
of the machine.
