Electrochemical deburring

Electrochemical deburring is a fast process. Typical process times are 5 to 30 s for smoothing the surfaces of manufactured components. Owing to its speed and simplicity of operation, electrochemical deburring can often be performed using a fixed, stationary cathode tool. The process is used in many apphcations, and is particularly attractive for the deburring of the intersectional region of cross-drilled holes.

Electrochemical grinding and electrochemical deburring are techniques related to electromachining in which excess metal is removed by a combination of mechanical abrasion and anodic dissolution. 

Electrochemical deburring is another modification of electrochemical machining carried out with smaller-scale ancillary and control equipment. It is used essentially to remove sharp corners and other imperfections and hence to finish metal components which have been manufactured by mechanical machining its...

Several electrochemically based methods are employed in the metals processing industry because of their ability to manufacture metal articles or components which are difficult or impossible to produce by traditional mechanical workshop techniques. The most important methods are electroforming and a group used for the controlled removal of metal, i.e. electrochemical machining, grinding and deburring.
