I am looking at buying a vibratory deburring machine to deburr gears. 6" O.D. To 3" O.D. 1" face width. I have looked online at Burr King's 4.5 cu. ft. And Mr. Deburrs 6.0 cu. ft. machine. I have no experience with these or any other types of vibratory finishing machines. Does anyone here have any experience with these? Any help or advice would be greatly appreciated.
