Honing, brushing and polishing machine for continuous precious or non-precious metal profiles of any cross sectional shape

摘要

The invention concerns a machine designed for the operations of honing, brushing and polishing to be performed automatically on continuous profiles or preformed chains in precious or non-precious metal of any cross section.- Particularly original is the fact that the machine includes one or more pairs of opposed and mutually tangential brushes that can be inclined at will around the axis of the product being treated so as to "brush" it homogeneously and all around.- Another feature is the fact that the pair of opposed brushes rotate in opposite directions so that they do not wear each other out appreciably.
