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. The electrode of the embodiments of the invention could also be made by method of manufacturing including formation of a groove pattern on a surface of a hollow conductive block by laser ablation of portions of the hollow conductive block and with or without formation of a dielectric material in the groove pattern. Additional methods involving photo-polymerization, selective ablation, plating and reverse ECM for recessed lands are disclosed.
