Soft Center
Soft centers are a special version of the dead center in which the nose is deliberately left soft (unhardened) so that it may be readily machined to the correct angle prior to usage. This operation is performed on the headstock center to ensure that the center's axis is aligned with the spindle's axis.

Famous quotes containing the words soft and/or center:
“Beautiful glooms, soft dusks in the noon-day fire,—
Wildwood privacies, closets of lone desire,
Chamber from chamber parted with wavering arras of leaves,—
Cells for the passionate pleasure of prayer to the soul that grieves,
Pure with a sense of the passing of saints through the wood,
Cool for the dutiful weighing of ill with good;—”
—Sidney Lanier (1842–1881)
“Against the Word the unstilled world still whirled
About the center of the silent Word.”
—T.S. (Thomas Stearns)
