Maintenance techniques have come a long way.
The first maintenance technique ever implemented was the REACTIVE MODE (If it ain’t broke, don’t fix it).
The next step in the evolution of maintenance was the time based PREVENTATIVE MODE. Bearings were greased, belts were changed, and machines were rebuilt, according to wear and tear and the age of the machine.
However, machines would still fail with no warning, causing the unplanned down-time and no one knew if the machines and parts being repaired or replaced really needed to be repaired or replaced.
As technology advanced and the need for machine reliability increased, the PREDICTIVE and PROACTIVE MODES were developed. Using this technique we can analyze such things as Vibration, Ultrasonic, Oil and Temperature signatures and predict when maintenance should be performed (Predictive Maintenance). Using these same technologies, we can also determine why maintenance is needed and correct the root cause of the problem (Proactive Maintenance). This allows a company to plan down-time and repair machinery on a regular maintenance schedule. The machinery and parts that need to be repaired or replaced are, and the ones that don’t need to be repaired or replaced aren’t.
