  • Patent number: 10661407
    Abstract: A hand-held machine tool (1) for sanding or polishing a workpiece features a housing (2); a motor (4) for rotating a tool shaft (5) of the machine tool about its axis of rotation (6); and a backing pad (3) for releasable attachment of a sanding or polishing element thereto and eccentrically attachable to the tool shaft by an eccentric element (11) to allow the backing pad to perform a working movement. The machine tool implements different working movements of the backing pad attached thereto. The housing includes first magnetic elements (16) facing the backing pad. The backing pad attached to the eccentric element includes second magnetic elements (17) facing the housing. The machine tool implements a first working movement if a magnetic force is active between some first and second magnetic elements and a second working movement if no magnetic force is active between the first and second magnetic elements.

  • Patent number: 10586665
    Abstract: An electric power tool has a tool receptacle and a tool housing in which a drive motor for driving the tool receptacle is arranged. The drive motor is switchable on and off via an electric switch. An operating part for indirectly actuating the switch is arranged on the tool housing and extends approximately parallel to a longitudinal axis of the tool housing. The operating part is lever-like and is pivotably arranged on the tool housing. An actuating member of the switch is displaceable approximately parallel to the longitudinal axis by an actuating force that acts on the operating part approximately perpendicularly to the longitudinal axis. The drive motor is switched on by the actuating force acting on the operating part against a restoring force of the switch, and the drive motor is switched off automatically, via the restoring force, when the operating part is released by a user.

    Abstract: An improved hand-held power tool is provided which can effectively reduce whirling vibration caused by imbalance of a rotating element. The power tool has a grip that is connected to a tool body and designed to be held by a user and a self-synchronous mechanism that reduces whirling vibration caused in the tool body or the grip when the tool bit is driven. The self-synchronous mechanism is of a phase variable type, having a rotating body which serves as a vibrator and is rotationally driven by a driving source different from a driving source for the tool bit. The self-synchronous mechanism is disposed in the tool body or the grip in which whirling vibration is caused, and arranged such that a phase of vibration of the rotating body is automatically tuned to a phase of the whirling vibration, thereby reducing the whirling vibration.

  • Publication number: 20140295736
    Abstract: The present relates to an apparatus and method for blending added material with base material on manufactured components. The apparatus comprises an abrasive device having an abrasive surface for removing exceeding added material, and a guide fixed to the abrasive device. The method determines a trajectory of the abrasive surface with respect to a manufactured component: determines which of a plurality of contact points of the guide shall be in contact with the manufactured component along the trajectory; actuates the abrasive device; and controls position and angle of the abrasive surface en the manufactured component along the trajectory, while keeping the determined contact point in contact with the manufactured component. A force is applied to the abrasive device when the abrasive surface is in contact with the manufactured component and transferred when the guide gets in contact with the base material.
