General Description
Lathe Bed
The lathe bed (A, Fig. 10) 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 in the stand below
headstock.
Headstock
The headstock (B, Fig. 10) is cast from high
grade, low vibration cast iron. It is bolted to
the bed by four screws with two adjusting
screws for alignment. In the head, the spindle
is mounted on two precision taper roller
bearings. The hollow spindle has Morse
Taper #5 with a 1-1/2" bore.
Carriage
The carriage (A, Fig. 11) is made from high
quality cast iron. The sliding parts are smooth
ground. The cross slide is mounted on the
carriageandmovesonadovetailedslide
which can be adjusted for play by means of
the gibs.
The compound slide (B, Fig. 11), which is
mounted on the cross slide (C, Fig. 11), can
be rotated through 360°. The top slide and the
cross slide travel in a dovetail slide and have
adjustable gibs. A four way tool post is fitted
on the top slide.
Four Way Tool Post
The four way toolpost (D, Fig. 11) is mounted
on the top 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.
Apron
The apron (E, Fig. 11) is mounted to the
carriage. In the apron a half nut is fitted. The
half nut gibs can be adjusted from the outside.
The half nut is engaged by use of a lever.
Quick travel of the apron is accomplished by
means of a bed mounted rack and pinion,
operated by a hand wheel on the front of the
apron.
