Glass Nozzle Polishing Technique

Nozzles for use in projecting ink droplets for ink jet printing must have precise exit characteristics. These characteristics include flatness of the nozzles and nozzle array exactly perpendicular to the axis, an optical polish, and edges of nozzles chip free and slightly rounded.

After a normal lapping procedure to obtain flatness, eliminate the normal rough polish step, and do only a final polish with a soft and extremely fine cloth pad with Iu Cerium oxide. This pad is able to maintain the flatness of glass nozzles with an excellent surface finish.
