Main parts of Lathe Machine
The Bed:
The lathe bed is a mounting and
aligning surface for the other machine components. Viewed from the operating
position in front of the machine, the headstock is mounted on the left send of
the bed and the tailstock on the right. The bed must be bolted to a base to
provide a rigid and stable platform.
1 Head Stock:
The head stock is the part of the lathe which
serves as a housing for the driving pulleys and back gears, provides bearing
for the machine spindle and keeps the latter in alignment with the bed. It is a
fixed part which will present on the left side of the lathe bed. Head stock
will consists of a hollow spindle and drives unit like main spindle, feed
reverse lever, live center cone pulley etc., The tapered bar with pointed or
projected end is going to grip the work piece between two centers of lathe bed.
1 Carriage:
The lathe carriage serves the purpose of supporting, guiding
and feeding the tool against the job during the operation of the lathe. The
carriage will present between head stock and tail stock which will slides on
the bed ways of the lathe bed. The carriage will give feed to the tool and it
holds the tool, for taper turning the feed is cross feed, for turning it is
longitudinal feed. The carriage consists of the following parts.
- Saddle
- Compound rest
- Cross slide
- Tool post
- Apron
TailStock:
The tailstock supports long work that would otherwise sag or
flex too much to allow for accurate machining. Without a tailstock, long pieces
cannot be turned straight and will invariably have a taper. Some tailstocks can
be intentionally misaligned to accurately cut a taper if needed. The tailstock
has a centering device pressed into a shallow, specially drilled hole in the
end of the work piece. The center can be either "live" or "dead.
