Apparatus for metal-cutting machining of wear-affected bit holders of road milling machines, and use of an apparatus for overhauling such wear-affected bit holders
Abstract:
An apparatus for metal-cutting machining of wear-affected bit-head-proximal end regions of bit holders of road milling machines encompasses: a rotary actuator having an output member rotating around an actuator rotation axis; at least one material-removing tool, rotatable around a tool rotation axis, which is coupled or couplable to the output member so as to rotate together; a positioning arbor, extending along an arbor axis, which is embodied for introduction into a bit receptacle opening of a bit holder and which comprises an abutment segment, located radially remotely from the arbor axis and facing away from the arbor axis in a direction having a radial component, which is embodied for abutment against an inner wall of the bit receptacle opening. A material-removing region, populated with cutting edges, of the material-removing tool is arranged between the positioning arbor and the output member.
