  • POLISHING DEVICE
    Publication number: 20210187698
    Abstract: A polishing device is held on a robot arm and has a support plate, a polishing disc held on the support plate, a drive moving the support plate in a plane, and a metering device for feeding a polishing agent to the working side of the polishing disc. An application nozzle of the metering device is guided through an open central axis of the support plate, the polishing disc having a central opening for allowing the passage of the polishing agent metered in computer-controlled manner.

  • METHOD FOR PARTIALLY GRINDING A SURFACE AND GRINDING DEVICE FOR CARRYING OUT THE METHOD
    Publication number: 20210008682
    Abstract: A method for removing a flaw on a treated, finally painted surface by grinding involves, after the flaw has been detected, moving a flexible abrasive sheet to the surface and pressing it against the flaw to be machined in such a way that the flaw is detected by a sensor system, which is operatively connected to a robotic arm carrying the grinding plate. The abrasive sheet, which is designed as an abrasive belt, is fed to the grinding plate and the abrasive sheet being pressed against the flaw.

  • Abrasive wheel for hand-guided grinding machines, in particular abrasive cutting-off wheel
    Patent number: 5584755
    Abstract: An abrasive wheel, in particular an abrasive cutting-off wheel, comprises an annular cylindrical inner support of metal and an abrasive ring surrounding the latter, both being connected with each other. The abrasive ring projects on both sides from the support in the direction of the common axis. The abrasive ring can be ground off completely. The support is re-usable or at least recyclable.
