Power Feed
Both the carriage and cross slide have power feed
capability when the carriage is engaged with the
feed rod. The rate that these components move
(feed rate) is controlled by the headstock and
gearbox lever positions.
The Feed Direction lever (see Figure 45) on the
headstock reverses the rotation of the headstock
gearbox, and the direction of carriage and cross
slide feed.

Feed rate and spindle speed must be considered
together. Keep in mind that the feed rate is
expressed in the amount of travel per revolution
of the spindle. The sources you use to determine
the optimum spindle speed for an operation will
also provide the optimal feed rate to use with
that spindle speed.
Often, the experienced machinist will use the
feeds and speeds given in their reference charts
or web calculators as a starting point, then
make minor adjustments to the feed rate (and
sometimes spindle speed) to achieve the best
results.
The carriage can alternatively be driven by the
leadscrew for threading operations (refer to
Inch-Thread Dial on Page 36).
