Technician
Next Service Date
This creates a maintenance history and helps identify recurring failures.
Track Machine Operating Hours
Maintenance should often be based on operating hours, not only calendar time.
For example:
A machine operating:
8 hours/day
will experience significantly more wear than one operating:
2 hours/day
Track:
Machine Hours + Cutting Hours + Maintenance Hours
This creates a better basis for preventive maintenance planning.
Monitor MTBF and MTTR
Two useful maintenance metrics are:
MTBF
Mean Time Between Failures
A higher MTBF generally indicates better reliability.
MTTR
Mean Time To Repair
A lower MTTR generally means faster recovery.
The goal is:
Increase MTBF + Reduce MTTR = Higher Machine Availability
Monitor Machine Vibration
Unexpected vibration can indicate:
- Blade imbalance
- Bearing wear
- Alignment problems
- Loose components
- Drive-system issues
If vibration increases suddenly, stop the machine safely and investigate.
Monitor Machine Temperature
Watch for abnormal temperatures in:
- Motors
