Electrolytic polishing machines

The Murua range of electropolishing machines enable workpieces to be polished while retaining their geometry. The operation consists in immersing the workpieces in an electrolytic bath covering all the surfaces. By agitating tiny particles of the medium coupled with electrolysis, a surface layer of metal is dissolved making the surfaces smoother and more polished.
