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

摘要

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.
