General operating instructions
4.21.1 Longitudinal turning
In the straight turning operation, the tool
feeds parallel to the axis of rotation of the
workpiece. The feed can be either manual
- by turning the handwheel on the lathe
saddle or the top slide - or by activating
the automatic feed. The cross feed for the
depth of cut is achieved using the cross
slide.

4.21.2 Face turning and recessing
In the facing operation, the tool feeds per-
pendicular to the axis of rotation of the
workpiece. Feed is done manually, using
the cross-slide hand wheel. The infeed for
cut depth is made with the top slide or
lathe saddle.
