With the transfer bar anti-vibration system

Our new software reduces oscillations to one tenth, preventing part drops and motor wear.

Vibrations are a critical aspect of automation systems because they affect machine performance and service life. These oscillations can cause part falls and stop production.

In our commitment to offer the most advanced automation systems, we have developed an antivibration system for transfer bars, which significantly reduces oscillations. The stability that the system provides to the bars improves their performance and extends the life of the motor.

The anti-vibration system reduces the vibrations that occur when the transfer shafts move, especially at the beginning and end of the movement. As with the transfer shafts, this technology could be applied to any other machine.

The vibratory displacement is reduced to one tenth, to such an extent that the reduction is visible to the naked eye. The following graph shows the evolution of the displacement measured on a transfer shaft with and without the anti-vibration system activated. In this case the vibration has been reduced 11 times.

Benefits of the system

  • With the reduction of vibration in the transfers, the sheet metal parts do not fall, so there is no need to stop the machine for an operator to solve the problem. This increases productivity and press OEE.
  • When vibration is reduced, the durability of the machine is greatly extended, and the frequency of maintenance stops is also significantly reduced.
  • The service life of the mechanical and electrical parts of the machine is extended and breakdowns are avoided. With the anti-vibration system, when the motor must exert force, the oscillations are much smaller, as shown in the table. This means that the degree of wear suffered by the motor with this system is much lower.

This technology can be implemented in both new and old machines, so it offers great flexibility:

• It is done by introducing some changes in the PLC software or in the axis drives, so it can be applied to any equipment.
• No mechanical or electrical changes are required on the machine.


The implementation of the system is very simple and requires little time. As an initial step, a Fagor Arrasate technician analyzes the shaft with a hand-held electronic device. This examination is done in one minute.

Afterwards, and considering the results of the analysis, the technician introduces some changes in the PLC software or, without touching the PLC software, introduces some changes in the Drive of the axis. This step only takes about one hour of work.
