27. Lathe is the oldest machine tool,
stemming from the early tree lathe,
which was turned by a rope passed
around the work and attached to a
spring branch overhead. The work
was supported by two adjacent
trees. The operator’s foot supplied
the motion. The tool was held in the
operator’s hand. Later a strip of
wood called a “lath” was used to
support the rope and hence named
as a lathe.

34. ORIGINAL UNFINISHED CASTING OF
PISTONS – FINISHED PISTONS

35. •At first, heat the die and spray
coating (chromium nitride)
inside the cavity.
•Then melt the metal and
convey it through a ladle.
•After that, slowly pour the
liquid metal into the cavity.
•Then wait for it to solidify.
•Next, take out the part after
opening the die.
•Finally, machine the part as
necessary.
CASTING PROCESS

36. FINAL CASTING

37. DIE OR MOLD MATERIAL
Die casting is a manufacturing
process in which molten
metal is poured or forced into
steel molds. The molds—also
known as tools or dies—are
created using steel and are
specially designed for each
project. This allows each
component to be created with
accuracy and repeatability.

38. CASTING MATERIAL
Metals are some of the
most commonly used
materials for casting,
particularly those with low
melting points, such as
aluminum and zinc. Metals
like iron, steel, brass,
bronze, and lead can also
be cast, but they require
the use of more advanced
equipment and materials.

98. TYPES OF LATHES
1. A Speed Lathe Machine is
a high-speed, hand-operated,
mainly used by woodworkers.
It can provide a spindle speed
from 1200 to 3600rpm.
The machine comes with a
very simple design, it
contains headstock, bed,
tailstock, and tool post.
These machines are used for
woodturning, furniture
making, metal polishing,
spinning, and centering.

99. TYPES OF LATHES
2. Engine Lathe – These lathes emerged during the
Industrial Revolution and originally used steam power
for operation before later being fitted with gas or electric
motors. The engine lathe is considered as the most
common type of manual lathes, which are widely used
in all machine shop applications. The engine lathe or
center lathe can perform operations such as turning,
end face, grooving, knurling, and threading.

100. Tool-Room Lathe – A high precision lathe having a
gearbox in the headstock offering a extended range of
thread pitches for both internal end external threads
and feeds. It has a low spindle runout and precision
guideway and leadscrews offering high stability, low
clearances and backlash. It is used for making
precision components in the tool room.
TYPES OF LATHES

101. Capstan and Turret Lathes – A capstan and turret
lathe is a production lathe. The turret head is mounted
on the ram fitted with turret slides longitudinally on the
saddle. Turret head has a hexagonal block having six
faces with a bore for mounting six or more than six
tools at a time.
TYPES OF LATHES
The main difference between the capstan and turret
lathe machine is the capstan lathe is fast because of
light construction but the turret lathe is slow (rigid
construction).These machines are used for mass
production.

102. DIFFERENCE BETWEEN TURRET AND
CAPSTAN LATHE

103. TYPES OF LATHES
These lathes utilize a computerized system that
results in high precision and accuracy. The popularity
of these lathes has led to them replacing many other
lathe types in machinist shops.
CNC Lathes: The CNC meaning can be defined as a
process in which pre-programmed computer software
dictates the movement of factory machinery and tools.
As a result, manufacturers can produce parts in less
time, reduce waste and eliminate the risk of human
error.
