Estimate the operational life of your finishing media in hours, cycles, and days. Understand when to expect media replacement and plan your maintenance schedule.
Ceramic media wears through abrasive action — the media itself is abraded as it removes material from workpieces. Factors increasing wear: harder workpiece material, higher machine amplitude, aggressive cutting compounds, and finer media grades (more surface area to wear). Typical wear rates: 0.5–2% of media weight per cycle.
Media should be topped up regularly (daily or weekly) to maintain the correct media:parts ratio. When media loses 40-60% of its original weight, it should be fully replaced.
Steel media wears through gradual surface deformation and chip formation. The dense, hardened steel resists abrasion, resulting in extremely low wear rates: 0.01–0.05% per cycle. Steel media can last 5,000–20,000+ machine hours before replacement.
However, steel media requires rust prevention — if media rusts, it must be replaced immediately to prevent workpiece damage. Always store steel media with rust inhibitor and never leave it dry in the machine.
These calculations assume proper media maintenance (regular top-ups for ceramic, rust prevention for steel). Poor maintenance can reduce actual media life by 30–50%. Glazed ceramic media (metal fines packed into pores) should be stripped or replaced to restore cutting action.
