摘要:
Machine servant à usiner des pièces, en particulier une perceuse-fraiseuse automatisée à commande numérique, comprenant une table de fixation (2, 3) supportant une pièce (41), un ou plusieurs ensemble(s) outil(s) (10, 11, 26) servant à usiner la pièce, et des éléments d'avance et de guidage (8, 9; 24, 25, 27, 43) agencés de façon à permettre le positionnement et un mouvement relatif simultané entre les ensembles outils (10, 11, 26) et la pièce (41), dans le sens longitudinal aussi bien que dans le sens transversal de la pièce. La table de fixation (2, 3) est composée de deux parties, et les ensembles outils (10, 11, 26) sont installés sur un dispositif de guidage (8, 9; 24, 25) dans un espace intermédiaire (4) s'étendant de façon transversale entre les tables de fixation (2, 3). En outre, un dispositif (30, 44; 27, 43) servant à serrer et à faire avancer la pièce (41) est placé de chaque côté de l'espace intermédiaire et transversal (4), le dispositif de serrage et d'avance (30, 44, 27, 43) étant agencé de façon à faire avancer la pièce (41) de manière successive et alternée, l'élément se trouvant à l'avant (44) dans le sens de l'avance étant agencé pour saisir la pièce (41) lorsque celle-ci a été amenée à la position qui convient par l'élément arrière (30).
摘要:
An apparatus for drilling plates of glass, marble and similar stony materials comprises a drilling device (DF) having two opposite heads (T, T') for carrying out respective coaxial incisions making up a hole onto two opposite surfaces of a plate under working (L). Each head (T, T') comprises at least a first and a second drilling assembly (G1, G2), the latter being movable on its respective head (T, T') in a perpendicular direction with respect to the drilling axis (A2), so as to take several alternative positions. The variation of the position of the second assembly (G2) with respect to the first assembly (G1) enables to vary the distance between the two holes or their angular position, and to make simultaneously two holes onto the plate (L), even quite close to one another, without moving the whole drilling device.

@ A machine is disclosed for drilling sheet-like materials, in particular for drilling holes at preset locations on glass, crystal glass, and the like plate blanks, which includes a feed-in station (1) and a drilling station (2). The feed-in station (1) is provided with a means of sliding a plate blank (3) to be drilled, forward, which has a plurality of rollers (5), at least some of which are driving rollers, the rollers being effective to impart a forward movement to the plate blank (3) and provided with a means of combining this forward movement with an approaching movement of the plate blank (3) toward an abutment member connected to the frame of the feed-in station (1).
摘要:
A machine for processing of workpieces, especially a computerized numerically controlled drilling and milling machine, comprising a worktable (2, 3) for the support of a workpiece (41), one or more tool assemblies (10, 11, 26) for processing of the workpiece, and feeding and guiding means (8, 9; 24, 25; 27, 43) arranged to provide for positioning and simultaneous relative movement between the tool assemblies (10, 11, 26) and the workpiece (41) in a longitudinal as well as a transverse direction of the workpiece. The worktable (2, 3) is in two parts, and the tool assemblies (10, 11, 26) are arranged on a guiding means (8, 9; 24, 25) in a transversely extending intermediate space (4) between the worktables (2, 3). Further, a means (30, 44; 27, 43) for clamping and feeding of the workpiece (41) is provided on each side of the transverse intermediate space (4), the clamping and feeding means (30, 44; 27, 43) being arranged for successive alternating feeding of the workpiece (41), the forward means (44), as viewed in the feeding direction, being arranged to take over the workpiece (41) when this has been fed to a suitable take-over position by the rearward means (30).
摘要:
A fixture (7) for drilling sheets (2) of fragile material is connectable to a movable machining head (1) having a supporting structure (3) and a rotary member (4), and includes a supporting frame (10), a shank (12) for connecting the supporting frame (10) to the supporting structure (3), and a first (18) and at least a second (19) powered spindle for a first (18a) and, respectively, a second (19a) drilling tool and extending in opposite directions with respect to the supporting frame (10); the spindles (18)(19) being rotated about respective axes (20) parallel to each other by a transmission (22), an input member (23) of which is connected to the rotary member (4) of the machining head (1) .
摘要:
A spindle assembly for machining a cast workpiece includes a fixture that provides rotational movement to the workpiece around a fixture axis. A first spindle provides rotational movement to a cutting tool around a first spindle axis and a second spindle provides rotational movement to a second cutting tool around a second spindle axis. The first spindle axis and the second spindle axis are transverse to the fixture axis. The fixture is disposed between the first spindle and the second spindle. The pivotal movement of the fixture provides access to opposite sides of the workpiece to the first spindle and the second spindle enabling the cutting tools to simultaneously cut opposing sides of the workpiece. The first cutting tool and the second cutting tool are replaceable by a third cutting tool and a fourth cutting tool to cut an alternative or different aperture into the workpiece.
