A method is described to prepare shaped steal test-pieces (1) for tensile under corrosion fatigue tests, which provides for contacting a test-piece (1) subject to rotation about its longitudinal axis and, each time a disk (10) of sand paper, also rotating, the contact being ensured by the own weight of the test-pieces itself. A device for carrying out this method is also described, which comprises a swinging arm (2) at an end of which the test-piece (1) is rotatably mounted, being driven by a motor (5), all these being mounted on a support central table (6), substantially stationary, around which a support (7) can rotate, having an annular shape on which a number of abrasive disks (10) are mounted, each on a rotatable shaft (9), to be successively positioned at the processing station in front of said supporting arm (2). |
