How is the service life of finishing pads evaluated? What are the warning indicators for replacement?
Life assessment requires comprehensive monitoring of the following indicators:
| Monitoring Metric | Normal Range | Replacement Warning |
|---|---|---|
| Surface Porosity Change | Initial value ± 5% | > ± 15% |
| Elastic Recovery Rate | > 92% | < 85% |
| Friction Coefficient Stability | Fluctuation < ± 0.02 | Fluctuation > ± 0.05 |
| Slurry Consumption Rate | Baseline ± 10% | Increase > 25% |
Smart Monitoring Solution: We offer optional embedded sensor pads that transmit real-time pressure/temperature data to customer MES systems. Professional surface topography analysis is recommended after every 500 polishing cycles.
