Abstract: front page image
(EN)A turret which can efficiently mount a number of cutting tools for a machine tool such as a numerically controlled lathe or the like. An indexing shaft (9) mounting the turret (8) is disposed in parallel with the surface of the bed, and at right angles to the axis (S) of a spindle (2) for holding a workpiece (W), but does not cross the axis (S). The turret (8) incorporates a polygonal section wherein the respective side surfaces form cutting tool mounting surfaces (F). The respective tool mounting surfaces (F) accomodate standards for mounting tool retainers (H), so that a plurality of tool retainers (H) can be mounted at desired positions in the direction perpendicularly crossing the axis (S) in parallel with each other. When one of the tool mounting surfaces (F) is indexed to be disposed at a cutting position, it is disposed in parallel with the surface of the bed at the position not crossed by the axis (S). Accordingly, a number of cutting tools (T) can be mounted on the turret (8), and the turret (8) can still be simply reduced in its size. In addition, the cutting work can be safely conducted and yet improved in efficiency.
(FR)Revolver sur lequel plusieurs outils de coupe peuvent etre montes de maniere efficace; ce revolver destine a une machine tel qu"un tour a commande numerique ou autre machine identique. Un arbre d"indexage sur lequel est monte le revolver (8) est dispose en parallele a la surface du lit, et a angles droits rapport a l"axe (S) d"une broche (2) tenant une piece a usiner (W) mais ne coupant pas l"axe (S). Le revolver (8) comprend une section polygonale ou les surfaces laterales respectives forment des surfaces de montage (F). Les surfaces de montages permettent de monter une pluralite de dispositifs de retenue d"outils (H) des positions desirees dans la direction orthogonale a l"axe (S), paralleles entre eux. Lorsque l"une des surfaces de montage d"outils (F) est indexee pour etre disposee en une position de coupe, elle est disposee en parallele a la surface du lit en une position non traversee par l"axe (S). Par consequent, plusieurs outils de coupe (T) peuvent etre montes sur le revolver (8), dont les dimensions peuvent encore etre reduites. De plus, le travail de coupe peut s"effectuer de maniere sure et le rendement peut encore etre ameliore.
