A novel approach of jet polishing for interior surface of small-grooved components using three developed setups

Highlights A novel approach of multi-phase jet polishing is proposed using a developed polisher, consisting of solid, liquid and gas phases. An abrasive air jet polishing is suggested through a customized polisher, including solid and gas phases. After jet polishing, surface roughness Sa decreases from pristine 8.596 to 0.701 and 0.336 μ m, and Sa reduces 92% and 96%, respectively. Defect volume of unit area achieved by optimized parameters lessens 1/12 that of non-optimized ones.
