Although there are several types of deburring, electrochemical deburring (ECD) is a popular choice because it can be used for parts of any size or shape that are made from virtually any conductive metal. ECD is especially useful for small, intricate features.
According to Vectron Inc., ECD uses electrical energy directed only to specified areas on the part to remove burrs. The electrical energy is localized by means of a fixture/electrode that conforms to the configuration of the finished area. The energy is transmitted to the burr by an electrolyte chemical and dissolves it.
The part to be deburred is placed on a nonmetallic holder that locates an electrode in the exact area of the burr or burrs. The workpiece, which functions as an anode, is charged positively, the electrode (cathode) is charged negatively and an electrolyte solution is directed under pressure to the gap between the burr and the electrode. A very controlled radius is generated as the burr is dissolved.
Not only does ECD ensure that all burrs are consistently removed on every part, but it also eliminates costly and time-consuming hand deburring, achieves a controlled and blended radius at intersections, removes otherwise inaccessible burrs, and it increases quality and reliability.
Bear in mind that ECD is only effective on electrically conductive materials, other deburring processes must be used for processing plastics and non-conductive materials.
