Essilor: continuously characterising an abrasive polishing fluid
A bath loaded with alumina particles, a lens quality that depends directly on it: FluidMiner brings continuous control where only spot lab analyses existed before.
Monitored equipment & environment
Tank and circuit of abrasive fluid containing suspended alumina particles, used for lens polishing.
What the client set out to solve
Stabilising the polishing process by controlling the bath's composition and evolution.
How the solution answers the need
FluidMiner continuously tracks overall concentration, particle rate and type, hardness and pH, to establish an operating baseline and catch formulation drift.
The business impact
More stable polishing quality, better-controlled fluid renewal, and fewer drifts linked to bath composition.
What comes next?
The solution is designed to become a continuous bath control and to extend to other polishing circuits with the same quality requirements.
