Abstract
A work-piece support member forming part of a spindle liner for use within the hollow spindle of a turning machine comprising: a disc dimensioned to fit closely within the hollow spindle, having a central aperture (A) sized to accept a work-piece; holding at least one helical spring (20) positioned adjacent to the aperture (A); such that in use the axis of said spring is held perpendicular to the axis of said work-piece such that part of the side walls of said spring or springs (20) abut against said work-piece and thereby firmly support said work-piece as it rotates with the hollow spindle about the axis of said hollow spindle.
Claims22
Apparatus for supporting a work-piece within a hollow spindle of a turning machine comprising:
- a first and second disc-assembly each with a central aperture of substantially the same size, defined by central aperture walls, configured to accept a work-piece;
- said first and second disc-assembly being held in adjacent configuration such that said central apertures generally align with each other;
- and at least one spring/resilient-member housed between adjacent first and second disc-assemblies;
- within a channel formed by at least a pair of grooves, one within each disc-assembly, and located adjacent at least part of said aperture walls of each disc;
- such that part of the spring/resilient member protrudes inwardly beyond said walls, so that in use part of said at least one spring/resilient member abuts against said work-piece and thereby directly supports said work-piece during rotation about the axis of said hollow spindle.
Apparatus for supporting a work piece within the hollow spindle of a turning machine comprising:
- a disc-assembly dimensioned to fit closely within the hollow spindle, having a central aperture sized to accept said work-piece;
- said disc-assembly holding at least one helical spring positioned adjacent to the aperture;
- where in use, the axis of said spring is held substantially perpendicular to the axis of said work-piece such that part of the side walls of the at least one spring abut against said work-piece and thereby firmly support said work-piece as it rotates with the hollow spindle about the axis of said hollow spindle.
