Abstract
Barrel finishing sometimes called mass finishing is a process in which mechanical means are used to remove burrs in a mass production scale. It can perform multiple tasks simultaneously, but removes all edges and surfaces exposed to interaction with the media. Deburring of the plated workpieces is therefore considered to be difficult. Plated workpieces are now made by shearing, punching or forming plated sheets or ribbons. There is a need to investigate method of deburring or radiusing the workpiece edges in minimizing the thinning of the plated layer. Methods using centrifugal and vibratory barrel finishing along these lines are shown, and film thickness after deburring is indicated.
In ordinary barrel finishing methods, the plated layer is removed from the cut or worked edges of the workpieces. It is shown that deburring and plating can be performed simultaneously using mechanical plating methods, and the limitation of the deburring abilities of these methods is shown.
