Abstract:
1. A milling head comprising: a base body having a plurality of first bores that are substantially parallel to a longitudinal center axis of the base body and a plurality of second bores that are non-parallel to the longitudinal center axis of the base body; a plurality of blade holders, each blade holder having a blade mounted thereon, each blade holder having a planar edge face and a shank with a surface having an angle with respect to the center longitudinal axis of the base body, the shank of each blade holder received in a respective first bore of the base body; a plurality of wedges received in a respective second bore of the base body, each wedge with a wedge face having an angle with respect a plane that is substantially perpendicular to the center longitudinal axis of the base body; an adjusting screw for moving each wedge within the second bore of the base body along the plane that is substantially perpendicular to the center longitudinal axis of the base body; a retaining element centrally located with respect to the longitudinal center axis of the base body, the retaining element having a plurality of planar edge faces, each planar edge face abutting a respective planar edge face of the plurality of blade holders to hold the plurality of blade holders securely in place, wherein movement of each wedge in a direction that is substantially perpendicular to the center longitudinal axis of the base body causes the wedge face of the wedge to press against the planar edge face of the respective blade holder and urge the respective blade holder in an axial direction along the center longitudinal axis of the base body.
