<p>Device and method for rotational processing of the ends of elongated hollow objects (1) as for example tubes or hollow profiles, comprised at least one controlled operation unit (2) which is disposed to transfer one rotating movement to an adjustable device (8) comprised at least one holder (9) for at least one processing tool (10). The holder for the processing tool is disposed to be adjusted in a radial, an axial and an angled direction in relation to the processed elongated hollow object's axial centre line (12). The invention is characterized in that the operation unit (2) is disposed to essentially be centred in the elongated hollow object's axial centre line (12) with the aid of at least one, to the operation unit connected, expandable body (16) which is brought to expand inside the elongated hollow object (1).</p> |
