Indexing on a lathe is typically used for workpiece layout
and other auxiliary operations that require equal distances
around the workpiece circumference, such as clock faces
or inlays.
By rotating the spindle handwheel (see
Figure
36
) to any
one of the marks on the degree indicator, the workpiece
can be positioned in 7.5° increments. Once the workpiece
is correctly oriented for the operation, the spindle lock
can be rotated full right to secure the position.
