  • Method and device for the production of bores
    Patent number: 8100197
    Abstract: A method and a device for the production of a bore with a special shape, for example a bore which deviates from a cylindrical shape or a bore with an undercut. First, a first bore portion is produced using an oscillatingly driven tool, the first bore portion having a shape deviating from a cylinder and having at least one projection projecting from the wall face of the first bore portion towards the bore center. Subsequently, when a bore with an undercut is to be produced, the tool is then at least partially rotated about its longitudinal axis, in order to produce a second bore portion which has a larger cross section than the first bore portion.
