With sanding or sanding machines with rotating sanding tools comprising sanding segments which are rotated in mutually opposite directions, according to the invention a more uniform sanding result and uniform wear on the tools is achieved with a method whereby the tools (10) which are rotated in the direction like a roller are rotated slightly faster than are the tools (1) which are rotated in the opposite direction. The necessary increase in speed has shown to be around 7 %, since the individual segments under the increased influence of the centrifugal force will thus obtain the same sanding pressure and herewith a uniform sanding effect for all of the sanding tools regardless of their direction of rotation in relation to the item.
On obtient, conformément au procédé de l'invention, par ponçage ou grâce à des ponceuses pourvues d'outils de ponçage rotatifs comprenant des segments ponceurs que l'on fait tourner dans des sens inverses, une usure des outils et un ponçage plus uniformes. En vertu dudit procédé, les outils (10) que l'on fait tourner dans un premier sens à la manière d'un rouleau tournent légèrement plus vite que les outils (1) que l'on fait tourner en sens inverse. La vitesse a dû être augmentée de 7 % environ, de sorte que chacun des segments subissant l'influence accrue de la force centrifuge possède la même pression de ponçage, et donc le même effet de ponçage pour chacun des outils, quel que soit leur sens de rotation par rapport à l'article.
