  • Micro-adjustable differential screw assembly
    Patent number: 7753626
    Abstract: A micro-adjustable differential screw assembly for providing fine adjustment of the axial and/or radial position of a cutting insert is disclosed. The micro-adjustable differential screw assembly can be mounted directly to a boring bar or to a mounting cartridge, which in turn, can be mounted to the boring bar. An axial micro-adjustable differential screw assembly provides fine adjustment of an axial position of the cutting insert, while a radial micro-adjustable differential screw assembly provides fine adjustment of a radial position of the cutting insert. The differential screw assembly includes a rotatable drive screw with threads of different thread pitches, and a non-rotatable adjusting screw with threads for mating with the drive screw.
