发明名称 EINSTELLBARER WERKZEUGHALTER FUER EINE BOHRSPINDEL
摘要 An adjustable tool holder for a boring bar has a first shank portion including a cutting tip keyed to a second shank portion to form a torsionally unitary cutting tool of constant exterior dimension receivable in a cylindrical bore in the boring bar. An adjusting screw is threadedly received in an axially extending bore in the first shank portion. The screw has an annular laterally enlarged head received and rotatable in an enlarged portion of the bore disposed in the second shank portion. An annular retaining bushing is press fit in a socket in the end of the second shank portion. The bushing retains the head of the adjusting screw within the enlarged portion of the axial bore, whereby rotation of the screw advances or retracts the first shank portion axially with respect to the second shank portion to a desired cutting position, the keying means between the mating shank portions preventing relative rotation therebetween.
