  • Multi-step bushing retention system for rotary machine tool
    Patent number: 5730560
    Abstract: A bushing system for guiding a bore forming apparatus within a machine tool includes a guide bushing with a central bore allowing passage of a rotating and axially moving tool, with the bushing having a generally cylindrical body with a radially extending flange having a free end and a stepped area adapted for engagement with the retainer. The retainer includes a complementary arcuate relief formed in an outer cylindrical surface for allowing the retainer to engage a stepped area formed in the guide bushing's radially extending flange. The retainer further includes a second radially extending flange with a diameter larger than the diameter of the retainer's body such that the second radially extending flange with abuttingly engage the free end of the guide bushing to maintain the bushing in axial register with a machine tool mounting fixture.
