Abstract:
The invention relates to a device (D) for removing by suction chips produced by a cutting machine tool by means of at least one tool (200) actuated by a tool holder module comprising a suction unit forming a low pressure. The tool (200) consists of a cutting part (210) and a standard fixing support (220). The inventive device is characterised in that it is provided with an suction hood (100) which is flexibly connected to said standard fixing support (220) of the tool (200) in such a way that a low pressure is produced around said tool (200) up to the end thereof and is fixedly and accurately connected to the tool holder module in such a way that the suction hood (100) is positioned with respect to the tool (200) forming a space therebetween, thereby enabling the tool to rotate with respect to the hood. Said invention is used for removing chips and fluids produced during a cutting process.
Abstract:
A machine tool has at least one working spindle, in which a tool receptacle for tool holders is provided. Furthermore, there is a tool-changing arm with a gripper, for a tool holder in order to transfer this tool holder between its magazine position, which is spaced apart from the tool receptacle, and its working position, in which the tool holder can be clamped into the tool receptacle. Orientation means are provided between the gripper and the tool holder supported by it and secure the tool holder in a nonrotatable manner on the gripper at least during its transfer between the magazine position and the working position and release it after it has been clamped into the tool receptacle, with the result that the tool holder can be rotated in relation to the gripper.
Abstract:
The present invention provides a machine tool capable of achieving a higher feed rate of a spindle and weight reduction while ensuring necessary stiffness of a column. The present invention includes: a bed; a saddle disposed on the bed to be movable in a Y-axis direction in a front view of the machine; a table disposed on the saddle to be movable in an X-axis direction; a column having a shape of a gate that is bridged over a travel range of the table and has right and left legs fixed on the bed and a beam connecting tops of the right and left legs; and a spindle head disposed on a front face of the beam to be movable in a Z-axis direction.
Abstract:
The present invention provides a machine tool whose width dimension is not increased even when it includes a tool magazine. The present invention includes: a bed 2; a saddle 4 disposed on the bed 2 to be movable in a forward and backward (Y-axis) direction in a front view of the machine tool; a table 5 disposed on the saddle 4 to be movable in right and left (X-axis) direction; a column 3 fixed on the bed 2; a spindle head 6 disposed on the column 3 to support a spindle 7 and movable in a vertical (Z-axis) direction; an automatic tool changer 10 disposed on a back face side of the column 3, wherein the column 3 has an opening A which allows the back face 3b″ side and a front face 3b′ side of the column 3 to communicate with each other, and the automatic tool changer 10 replaces a tool T on the spindle 7 side by a tool T1 on a tool magazine 11 side through the opening A.

Abstract:
A mechanism for coupling tooling cassettes (60) in a numerical control machining unit for a transfer machine of the type comprising a frame (10) with rails (11, 12) for moving (X arrow) a vertical knee (20) with two posts (21 and 22) also provided with rails (21a and 22b) on which a movable headstock (30) slides (Y arrow), with a spindle-supporting slide (40) passing through the headstock (Z arrow); and a magazine (50) for a tooling cassette (60) positioned on the headstock (30), surrounding the knee (20), and through which the slide (40) may pass, comprising a ring (5) supporting the cassettes (60) and rotatably mounted (R arrow) about the knee (20). The mechanism for coupling the cassettes (60) bears on the rotation guide (R arrow) of the ring (51) of the rotating magazine (50) around a circular track (52) integral with the frame (10) and provided at its base with a triangular way (52a) with rollers (62a, 62b) retained and guided therein, wherein said rollers are associated with said cassettes (60) for rotating with the cassettes (60) driven by the ring (51). The invention is useful for transfer machines, machining cells and the like.
