  • MACHINE TOOL
    Publication number: 20130216323
    Abstract: An automatic machine tool, particularly for producing a dental prosthesis of exact three-dimensional shape, includes a machining unit (200), a workpiece feed unit (300), a tool feed unit (400) and an operating and control unit. The machining unit (200) includes a machining tool (430) that is displaceable in three spatial directions and has a cardanic workpiece holder receptacle (210) that can be pivoted about two axes, wherein the workpiece holder receptacle (210) is arranged vertically and the machining of the workpiece is carried out in vertical arrangement so as to allow the dropping of chips.

  • Method for the metered discharge of a string of a viscous medium and feedpump for discharging a string of a viscous medium
    Patent number: 6623673
    Abstract: A method for the metered discharge of a string of a viscous medium, in particular of an abrasive medium containing solid particles, via a nozzle, in which the quantity of the medium is discharged as a function of the speed of the nozzle and is increased or reduced as a function of the acceleration or deceleration of the nozzle.

  • Method for the metered discharge of a string of a viscous medium and feedpump for discharging a string of a viscous medium
    Patent number: 6592349
    Abstract: A feedpump for discharging a string of a viscous medium containing solid particles. The feedpump includes a casing and two gearwheels drivable to execute an oppositely directed rotation and arranged in the casing so as in each case to form and maintain gaps relative to both walls of the casing and to one another. The gaps have a size adapted to the size of the particles in the viscous medium.
