Abstract
Apparatus for use in cutting a workpiece on different centers. The workpiece is mounted in a chuck on a spindle top. The spindle top is mounted on the upper end of a rotatable, vertical spindle shaft adjacent to a cutting tool in different positions spaced apart laterally relative to the spindle shaft axis. When the spindle shaft is rotated with the spindle top in one position, the tool will cut the workpiece on one center. In another position of the spindle top, the tool will cut on a different center.
