A structured preventive maintenance program is the foundation of servo press reliability.
## Daily Checks (Operator)
- Check lubrication oil level in centralized lubrication system
- Verify slide parallelism indicator reading
- Listen for abnormal noise during warm-up strokes
- Check air pressure for counterbalance and die cushion
- Verify safety light curtain and E-stop function
## Weekly Checks (Maintenance)
- Inspect all lubrication lines for leaks or blockages
- Check servo drive cooling fan operation
- Verify encoder cable condition at flex points
- Test brake function: measure stopping distance
- Review fault log for recurring alarms
## Monthly Checks
- Measure and record slide parallelism (front-back and left-right)
- Check all electrical connections for tightness
- Inspect motor coupling for wear
- Clean servo drive heatsinks with compressed air
## Quarterly Checks
- Replace lubrication oil filter elements
- Perform vibration analysis on main bearings
- Calibrate slide position measurement system
- Test all safety interlocks per safety standard requirements
## Annual Overhaul
- Replace main drive lubrication oil
- Inspect and measure main shaft bearings
- Perform full electrical insulation test on servo motor
- Full safety system certification
## Documentation
Record all measurements in a maintenance log. Trending data over time reveals developing problems before they cause failures.
