The different types of machine maintenance are:
1) Reactive Maintenance/ Run-to-Failure Maintenance:
This refers to repairs performed after a machine has already failed and it is unexpected and thus leads to emergency rushed repairs.
2) Preventive Maintenance:
This refers to any planned or scheduled machine maintenance that aims to identify and repair problems before they cause failure. It can be annual/bi-annual. But it cannot prevent asset failure between two schedules or unnecessary downtime.
3) Condition-based Maintenance:
It focuses on monitoring the current status of assets to undertake maintenance when evidence of decreasing performance or approaching breakdown is detected.
4) Predictive Maintenance:
It expands on condition-based maintenance by utilizing instruments and sensors to continuously evaluate machinery performance & flagging off any anomaly and its root cause before it results in a full-blown asset failure.
