stand (C) below the gearbox.
Headstock
The headstock (D) is cast from high grade, low
vibration cast iron. In the head, the spindle is
mounted in precision taper roller bearings. See

Carriage
The carriage assembly is composed of the Apron,
the Saddle, the Cross Slide, the Compound Rest,
and the four-way Tool Post.
Apron (G). Quick travel of the Apron for
positioning is accomplished by means of a bed-
mounted rack and pinion, operated manually by
the handwheel on the front of the apron, or
automatically by the feed direction handle.
Saddle (H). The saddle is made from high
quality cast iron and rides along the v-ways.
I
Cross Slide ( ). The cross-slide is mounted on
the saddle and used for cross feed operations. It
moves on a dovetailed slide which can be
adjusted for play by means of the gibs.
Compound Rest (J). The compound rest, which
is T-slotted and mounted on the cross slide, can
be rotated 360°, allowing tapers to be turned.
The compound rest travels on dovetailed ways,
with adjustable gibs.
