<p>The heat created by the contact of two metal parts, one of them rapidly moving has to be reduced in order to avoid a deformation or heat marks created on the surface of the processed object (2). The surface of the work-piece (2) can be treated immediately afterwards with a fast moving band (3) or similar device provided with a multitude of metal needles (5) or bristles deducting the heat from the object (2). There can also be bristle areas positioned between the cutting areas of the machining tool (1).</p> |
