🔧 Machine Maintenance
Machine maintenance is essential for maintaining the efficiency and extending the service life of machinery. It helps prevent unexpected downtime and reduces repair costs.
🛠️ Types of Maintenance
1. ✅ Preventive Maintenance (PM)
Performed at scheduled intervals (e.g., monthly, quarterly).
Tasks include:
- Lubricant and oil changes
- Cleaning
- Checking for looseness or wear
👉 Helps reduce the risk of unexpected machine failures.
2. 🕒 Corrective / Breakdown Maintenance
Maintenance is performed after a machine breaks down.
- Carries a higher risk of production interruption
- Suitable for backup or non-critical machines
3. 📊 Condition-Based Maintenance (CBM)
Maintenance based on monitoring actual machine conditions, such as:
- Temperature
- Vibration
- Noise
- Pressure
Tools used:
- Vibration Analyzer
- Thermal Camera
4. 🤖 Predictive Maintenance (PdM)
Uses AI and IoT technology to analyze data and predict when a failure might occur.
👉 Helps reduce costs and improve long-term performance.
🔧 Common Maintenance Tasks
| Task | Details |

| Cleaning | Dust, oil stains, heat dissipation |
| Tightening bolts/screws | Check for looseness |
| Sensor check | Verify operation and response |
| Electrical inspection | Terminals, grounding, relays, breakers |
| Pneumatic system check | Leaks, pressure levels, filters |
📅 Maintenance Schedule
| Frequency | Task Examples |
|---|---|
| Daily | Check for noise, vibration, oil leaks |
| Weekly | Check lubrication points, belt tension |
| Monthly | Oil changes, fan inspection, filter cleaning |
| Quarterly / Yearly | Check for worn parts, alignment, replace critical components |
📄 Essential Maintenance Documents
- Maintenance Checklist
- Log Book for repair and service records
- Machine Manual
- Maintenance History Report
🧰 Common Tools & Equipment
- Screwdrivers, wrenches, torque wrench
- Vibration analyzers
- Thermal camera

- Multimeter (for electrical testing)
“Maintenance” is the activity of maintaining the condition of machines/tools/various work equipment. Keep it in good condition and ready for use at all times. If there is a lack of good maintenance It will affect the performance of the machine. Risk of machine downtime Leading to breakdown problems, which will affect the production efficiency of the factory. Including various expenses that will occur including repair costs. Cost of time – lost opportunity and many more. Therefore, maintenance is a necessity that every factory should pay great attention to.
