Abstract (en)
[origin: EP0854040A2] A method is provided for improving the operation of ink jet components. The components are machined using known, conventional machining techniques. All of the machined surfaces are then treated using non-abrasive, intrinsically leveling polishing processes to eliminate particulate sources. The conventional machining may be any known technique, such as electro discharge machining. The polishing processes include, but are not limited to, electrochemical means such as electropolishing, electrochemical deburring, and electrochemical grinding. The polishing processes may further comprise vapor polishing, and laser treatment to reflow the machined surface. <IMAGE>
