Cutting oil purification enhances fluid lifespan by:

Removing Contaminants: Eliminates particles, tramp oil, and microbial growth that degrade oil quality.
Restoring Properties: Replenishes additives and adjusts pH levels to maintain optimal lubrication and cooling performance.
Preventing Degradation: Reduces oxidation and emulsification, which can compromise fluid effectiveness.
By maintaining the cutting oil in a clean and functional state, purification reduces the need for frequent replacements, leading to cost savings and reduced environmental impact.
