Abstract
A copy milling device for the production of in particular dental workpieces, comprising a carrier plate for a model body and a shaping blank, an arm which is arranged pivotably about a horizontal axis extending substantially normal to its longitudinal direction and which has a motor-driven machining tool for cutting shaping of a workpiece from the shaping blank and a tracing device for tracing the model portion, wherein the machining tool and the tracing device are mechanically and synchronously movably connected, wherein the copy milling device comprises a suspension device for the arm.
Claims50
A copy milling device for milling workpieces, the device comprising:
- a carrier plate for supporting a model body and a shaping blank;
- an arm pivotally mounted about a horizontal axis extending substantially perpendicularly to a longitudinal direction of the arm;
- said arm carrying a motor-driven machining tool for machining a workpiece from the shaping blank and a tracing device for tracing the model body, said machining tool and said tracing device being mechanically connected and movable in synchronicity;
- and
- a suspension device for said arm, said suspension device including a spring for compensating for the weight of the arm, said spring connecting said arm and a support that is mounted so as to be horizontally movable relative to the carrier plate.
A copy milling device for milling workpieces, comprising:
- a carrier plate for a model body and a shaping blank;
- a motor-driven machining tool for machining a workpiece from the shaping blank and a tracing device for tracing the model body, said machining tool and said tracing device being mechanically and synchronously movably connected;
- and
- a suspension device for an arm on which the machining tool and tracing device are mounted, said suspension device including a spring for compensating for the weight of the arm, said spring connecting said arm and a support that is mounted so as to be horizontally movable relative to the carrier plate;
- wherein said motor-driven machining tool is disposed or disposable for access by a user in a condition of use and including a gripping element for varying a position of said machining tool and said tracing device.
A copy milling device for machining workpieces, the device comprising:
- a carrier plate for a model body and a shaping blank;
- a motor-driven machining tool for machining a workpiece from the shaping blank and a tracing device for tracing the model body, said machining tool and said tracing device being mechanically and synchronously movably connected;
- a suspension device for an arm on which the machining tool and tracing device are mounted, said suspension device including a spring for compensating for the weight of the arm, said spring connecting said arm and a support that is mounted so as to be horizontally movable relative to the carrier plate in a longitudinal direction of the arm;
- and
- a holding element for mounting at least one of the model body and the shaping blank in said carrier plate.
A copy milling device comprising:
- a carrier plate for supporting a model body and a shaping blank, the carrier plate having at least one through opening formed therein configured to allow dust produced when milling the shaping blank to pass therethrough;
- a motor-driven machining tool for machining a workpiece from the shaping blank and a tracing device for tracing the model body, said machining tool and said tracing device being mechanically and synchronously movably connected;
- and
- a suspension device for an arm on which the machining tool and tracing device are mounted, said suspension device including a spring for compensating for the weight of the arm, said spring connecting said arm and a support that is mounted so as to be horizontally movable relative to the carrier plate in a longitudinal direction of the arm.
A copy milling device for the production of dental workpieces, comprising:
- a base plate, a carrier plate for a model body and a shaping blank,
- an arm arranged pivotably with respect to a horizontal axis, said axis extending substantially normal to a longitudinal direction of said arm and said arm having a motor-driven machining tool for cutting shaping of a workpiece from the shaping blank and a tracing device,
- said machining tool and said tracing device being mechanically and synchronously movably connected,
- wherein said model body and said shaping blank can be or are arranged in through openings of said carrier plate by means of disk-shaped holding elements,
- said holding elements each having a through opening for accommodating said model body and said shaping blank, respectively.
