  • Device for honing workpieces
    Patent number: 4551947
    Abstract: A device for honing workpieces. The device includes a rotatable and axially reciprocating honing tool which is guided by an upper and a lower end section in corresponding bearings of a workholding fixture, and also includes a drive rod between the honing tool and a machine spindle. This drive rod is flexible in the radial direction, which prevents out-of-balance at high rotational speeds of the honing tool as a result of excessive mass and excessive play in pivot bearings, while the associated uncontrolled vibrations are also prevented.
