Abstract
Apparatus for restoring a turret table toolholder guide station. The apparatus comprises a plurality guide rings each comprising precisely molded or machined inner and external circumferential surfaces, one guide ring being installed into each of the channels. Each guide ring has a portion of the ring circumference removed for facile, snap-in installation, but each guide ring retains a sufficient portion thereof that a toolholder inserted for guidance in the station is in substantially continuous, precise toolholder guiding contact with the inner circumference of the guide ring.
Claims5
A facilely reparable and maintainable turret table toolholder guide station comprising:
- a vertical bore centrally inaccessible in which a toolholder having predetermined diameter is generally concealed and reciprocably guided, said bore comprising a cylindrical wall of at least one predetermined diameter in which at least two generally concealed grooves are horizontally disposed;
- wherein said cylindrical wall forming the vertical bore comprises a stepped bore comprising an upper cylindrical section having a first diameter and a lower cylindrical section having a second diameter, said first and second diameters being of essentially different longitudinal lengths to accomodate the stepped configuration of the toolholder and
- at least two shape-retaining removable toolholder generally concealed guide annular wear strips one disposed in each groove and each having a predetermined diameter less than the adjacent diameter of the cylindrical wall and substantially the same as the adjacent diameter of the toolholder thereby providing a substantially continuous contact only between each replaceable annular wear strips and the toolholder.
