Abstract: In the paper is presented a machine for superfinishing external surfaces of cylindrical workpieces with diameters between 5 to 30 mm and length between 10 to 300 mm. The surface finish that is obtained for the workpieces is very high with the roughness values Ra between 0,4 - 0,2 ìm. The parts are placed between two cylinders that have a rotational movement and with nonparallel axis. This feature allow for the parts to have a rotation motion and a transverse motion simultaneously while the abrasive stones which have a reciprocation motion make the abrasion action on the workpiece surfaces.
The machine is automatically fed with parts and has a great productivity. An operator can work and control two these machines in the same time.

Brief Biography of the Speaker:
Badea Lepadatescu is currently an Associate Professor at the Faculty of Manufacturing Engineering of the Transilvania University of Brasov, Romania. He obtained his doctoral degree in 1998 in the area of machining through superfinishing process. After he gratueted he worked five years as design engineer at Roman truck factory in the field of manufacturing processes where designed many devices and special machines especially for superfinishing process. Started on 1982 he worked as research engineer at Transilvania University of Brasov, and after 1997 he is teaching at Faculty of Manufacturing Engineering department. His main academic interests include Tolerance and Dimensional Control, Manufacturing Engineering Processes, Automation Processes, and Renewable Energy Sources. The research accomplishments are reflected through publications in a six books and authored or co-authored over 120 papers published at international conferences. He has extensive experience in both experimental and theoretical research work having more than 50 contracts with factories to design and produce machines for machining processes. Also in the field of Renewable Energy Sources together with a team he made two wind turbines, one with horizontal axis for taking water, and one with vertical axis to produce electric energy. He has been speaker to international conferences, has moderated forums, organized workshops and sessions at major international conferences.
