Abstract: The invention relates to motor bearing components with features such as fine groove pitch (<100 microns), fine feature widths (<25 microns), varying groove depths and surface profiles in 3D for optimum bearing performance. A method for manufacturing the workpiece, the electrode design features to make the final part and the method for manufacturing such an electrode are disclosed. An electrode including a conductive block having the desired profile is disclosed. The electrode of the embodiments of the invention could be made out of a wide range of materials including hard and difficult to machine materials. The electrode can be made out of a solid blank, or a sleeve with hollow core or a sleeve with a filled core. Such an electrode can be used for achieving optimized groove geometry on the workpiece.
