Title (EN) ROTARY CUTTER
(FR) DISPOSITIF DE COUPE ROTATIF
Abstract: front page image
(EN)There are provided a pair of retaining plates (4) which are rotatable in unison on a rotary shaft (1) for a sawing machine such as a table saw or a radial saw or for a milling machine or the like, and a bearing cylinder (6) formed integrally with both the retaining plates (4) therebetween on the rotary shaft (1). A pair of clamping plates (8) are so mounted on the bearing cylinder (6) as to obliquely support a rotary cutter (13) at a predetermined angle with respect to the center axis of the rotary shaft (1), the rotary cutter operating to cut a groove (15) into a workpiece, and are secured under pressure to the retaining plates (4). By rocking the clamping plates (8) relatively between the retaining plates (4), the plates will tilt with respect to the center axis of the shaft (1). A number of cutting edges (14) formed on the outer periphery of the rotary cutter (13) have elliptical ends so that the floor of the groove will always be flat. The cutter (13) can be rotatably adjusted with respect to the clamping plates (8) on either side thereof.
(FR)Une paire de plaques de retenue (4) tournent a la meme vitesse sur un arbre rotatif (1) d"une machine a scier telle qu"une scie a table ou une scie radiale ou pour une fraiseuse ou autre, et un cylindre palier (6) forme en une piece avec les deux plaques de retenue (4) sur l"arbre rotatif (1). Une paire de plaques de fixation (8) sont montees sur le cylindre de palier (6) de maniere a supporter obliquement une scie rotative (13) avec un angle predetermine par rapport a l"axe central de l"arbre rotatif (1), la scie rotative decoupant une rainure (15) dans une piece a usiner, les plaques de fixation etant fixees sous pression aux plaques de retenue (4). En faisant basculer les plaques de fixation (8) entre les plaques de retenue (4), les plaques s"inclinent par rapport a l"axe central de l"arbre (1). Plusieurs bords coupants (14) formes sur la peripherie externe de la scie rotative (13) possedent des extremites elliptiques de sorte que le fond de la rainure soit toujours plat. La scie (13) peut etre ajustee de maniere rotative par rapport aux plaques de fixation (8) de chaque cote.
