Title (EN) FORM ROTARY DRESSER AND DRESSING METHOD
(FR) OUTIL DE DRESSAGE DE FORMES ROTATIF ET PROCÉDÉ DE DRESSAGE
(JA) 総型ロータリードレッサー及びドレッシング方法
Abstract:
(EN) A form rotary dresser, wherein the outer circumferential face thereof that is in contact with a grinding stone has an area on which diamond abrasive grains are disposed dispersedly and a slit area on which no diamond abrasive grains are disposed. A plurality of slit areas is provided inclined with respect to the axis of rotation. Along the edge on the downstream side of the slit area in the direction of rotation, a plurality of octahedron diamond abrasive grains is disposed with one face of the octahedron being parallel to the outer circumferential face.
(FR) L'invention concerne un outil de dressage de formes rotatif, dans lequel la face circonférentielle extérieure de celui-ci, qui est en contact avec une meule, possède une zone sur laquelle des grains abrasifs de diamant sont disposés de manière dispersée et une zone de fente sur laquelle aucun grain abrasif de diamant n'est disposé. Une pluralité de zones de fente est disposée de manière inclinée par rapport à l'axe de rotation. Le long du bord sur le côté aval de la zone de fente dans le sens de rotation, une pluralité de grains abrasifs de diamant de type octaèdre sont disposés de façon qu'une face de l'octaèdre soit parallèle à la face circonférentielle extérieure.
(JA) 総型ロータリードレッサーは、砥石と接触する外周面が、ダイヤモンド砥粒が分散して配置された領域と、ダイヤモンド砥粒が配置されないスリット領域とを有する。スリット領域は、回転軸に対して傾斜して複数設けられる。スリット領域の回転方向下流側のエッジに沿って、複数の8面体ダイヤモンド砥粒が、8面体のいずれか1面を外周面と平行にして配置されている。
