Description
To increase material removal speed of barrel polishing, centrifugal barrel polishing (CBP) was investigated. CBP was applied to a niobium pipe 76 mm diameter, and 16 μm from the surface layer was removed in 24 hours. This result was reported in this meeting last year. As the next step, CBP was applied to a niobium L-band single cell cavity. The relationship between removal speed and amount of the polishing media was investigated. The distribution of removal thickness along the surface was measured with ultrasonic thickness gage. Surface layer up to 25 μm deep was removed in 8 hours by CBP with GCT media. (author)
