Abstract: A new horizontal electropolishing facility has been developed by Ettore Zanon SpA (EZ) and implemented for the series production of the EXFEL cavities at EZ. Main electropolishing done according to EXFEL specification is the first step in the surface treatment process, that is essential to reach high performances.Particular attention has been dedicated to find the best configuration during qualification of the system. Correlation between process variables for industrial application, RF tests at room temperature at Zanon and vertical RF tests at 2 K at DESY are investigated, in order to optimize the removal of Niobium.The facility has been designed for industrial scope, in order to guarantee the required quality and a production rate of 4 cavities per week . One of the most important aspects for design has been the automation of the process that permits to have complete control on it.
