Title (EN) METHOD AND APPARATUS FOR SHARPENING A SAW CHAIN
(FR) PROCÉDÉ ET APPAREIL D’AFFÛTAGE DE CHAÎNE DE SCIE
Abstract:
(EN) What is disclosed is a new type of method and device for sharpening the saw chain (4) of a chain saw. In the first stage of the method, a rotating sharpener (12) is brought against the first cutter (18) to be sharpened of the chain (4) and the sharpener (12) is pressed against the first cutter (18) at a set sharpening angle in order to remove material from the cutting edge (8) of the first cutter (18). The chain (4) is then moved in its longitudinal direction to position the second cutter (19) for sharpening. In the second stage, the rotating sharpener (12) is kept rotating in the same direction as in the first stage and the rotating sharpener (12) is brought at a set sharpening angle against the second cutter (19) to be sharpened (19) in order to remove material from the cutting edge (8) of the second cutter (19).
(FR) L'invention concerne un nouveau type de procédé et un nouveau type de dispositif destinés à l'affûtage de la chaîne de scie (4) d'une scie à chaîne. Lors de la première étape du procédé, un aiguiseur rotatif (12) est amené contre le premier organe de coupe (18) à affûter de la chaîne (4), et l'aiguiseur (12) est pressé contre le premier organe de coupe (18) à un angle d'affûtage défini, afin d'éliminer un matériau à partir du bord de coupe (8) du premier organe de coupe (18). La chaîne (4) est ensuite déplacée dans sa direction longitudinale en vue de positionner le second organe de coupe (19) destiné à l'affûtage. Lors de la seconde étape, l'aiguiseur rotatif (12) est maintenu en rotation dans la même direction qu'à la première étape, et l'aiguiseur rotatif (12) est amené à un angle d'affûtage défini contre le second organe de coupe (19) à affûter (19), afin d'éliminer un matériau à partir du bord de coupe (8) du second organe de coupe (19).
