FIELD: machine engineering, apparatuses for activating surface and cleaning wire or round rolled piece, mainly at preparing them to application of metallic coating.
SUBSTANCE: hollow rotary shaft is mounted in base and it has at least one working unit in the form of two rotating abrasive end members mounted at opposite sides of shaft with possibility of lengthwise motion along axis normal to shaft and with possibility of introducing into cavity of shaft. Said abrasive members rotating around their own axis and around cleaned article provide abrasive action upon article surface.
EFFECT: possibility for selecting mode of cleaning due to matching revolution numbers of abrasive members and product feed and due to intensified action of abrasive members upon cleaned surface caused by their grain size.
