General Description
Lathe Bed
The lathe bed (A, Fig. 12) is made of high grade
cast iron. By combining high cheeks with strong
cross ribs, a bed with low vibration and high
rigidity is realized. Two precision ground vee
slideways, reinforced by heat hardening and
grinding, are an accurate guide for the carriage
and headstock. The main drive motor is
mounted to the rear of the bed.
Carriage
The carriage (B, Fig. 12) is made from high
quality cast iron. The sliding parts are smooth
ground. The cross-slide is mounted on the
carriage and moves on a dove-tailed slide which
can be adjusted for play by means of the gibs.
The compound slide (C, Fig. 12), which is
mounted on the cross slide (D, Fig. 12), can be
rotated through 360°. The compound slide and
the cross slide travel in a dovetail slide and have
adjustable gibs. A four-way tool post (E, Fig. 12)
is fitted on the compound slide.
Headstock
The headstock (F, Fig. 12) is cast from high
grade, low vibration cast iron. It is mounted to
the bed by four bolts with two adjusting bolts for
alignment. In the head, the spindle is mounted
on two precision taper roller bearings. The
hollow spindle has Morse Taper #5 with a 1-3/8"
bore.
Four Way Tool Post
The four-way tool (E, Fig. 12) post is mounted
on the compound slide and allows a maximum
of four tools to be mounted simultaneously.
Remember to use a minimum of two clamping
screws when installing a cutting tool.
