3. ABOUT THE COMPANY
 Him Teknoforge Ltd. is a leading manufacturer and
supplier of a wide variety of quality Forgings and
Machined Components (Blanks & Finished Heat Treated)
like Gears, Axles, Shafts, Non Gear, Assemblies, Sub
Assemblies, Spider Kits and repair kits. It commenced
production in 1982 with a Forging Unit at Baddi, Himachal
Pradesh, which was set up to supply quality forgings in
bulk to various Original Equipment Manufacturers (OEMs)
as well as Railways, Defense, Aftermarket and Exports.

4. MACHINED PRODUCTS
 Gears and Shafts
 Gear Box
 Axles
 Crown wheel &
Bevel Wheel Kit
 King Pins & Repair
Kits

5. BULL GEAR
It refer to larger of
two spur gear that
are in engagement
in any machine.

6. MATERIAL REQUIRED
Bull Gears are usually made
up of 20MnCr5 Grade.
CARBON = 0.17 – 0.22
SILICON = Max. 0.4
MANGANESE = 1.1 – 1.4
PHOSPHORUS = Max. 0.25
SULPHUR = Max.0.035
CHROMIUM = 1 – 1.3

7. APPLICATION
 Automobile Industries (mainly in Tractors and Trucks)
 Mining Industries
 Steel Plants
 Power Plants
 Paper Plants
 Fertilizer plants

8. PROCESSES INVOVED
1 Forging
2 Turning
3 Boring
4 Facing
5 Broaching
6 Drilling
7 Hobbing
8 Shaving
9 Deburring

9. FORGING:-
Forging is a
manufacturing process
involving the shaping of
metal using localized
compressive forces. The
blows are delivered with
a hammer (often a
power hammer) or a die.

10. TURNING:-
Turning is a machining
process in which a cutting
tool, typically a non-rotary
tool bit, describes a helical
tool path by moving more
or less linearly while the
workpiece rotates.

11. FACING :-
Facing is the act of
cutting a face, which is a
planar surface, on to the
work piece to produce
flat surface.

12. BORING :-
Boring is the process of
enlarging a hole that has
already been
drilled/forged by means
of a single/multi point
cutting tools. It is
mainly done to achieve
greater accuracy of the
diameter of a hole.

13. BROACHING
Broaching is a
machining process that uses a
toothed tool, called a broach,
to remove material.

14. DRILLING :-
Drilling is a material
removal process that
uses a drill bit to cut or
enlarge a hole or circular
cross section in solid
materials.

15. HOBBING :-
Hobbing is a machining
process for gear cutting,
cutting splines, and
cutting sprockets on
hobbing machine.
The teeth or splines are
progressively cut into
the workpiece by a series
of cuts made by a
cutting tool called a hob.

16. DEBBURING :-
Deburring is the process
of removal of unwanted
burrs which are
generated along the
edges of teeth of gear.

17. SHAVING :-
Gear shaving is free
cutting gear finishing
operation which removes
small amounts of metal
from the working surfaces
of the gear teeth.

18. PROJECT
 After manufacturing of Bull gears, soft inspection is done by the following
methods
ROCKWELL HARDNESS TESTER
 used to measure hardness of the gear
 Rockwell hardness C scale is used

19. PROJECT
VERNIER CALLIPER
A Digital Vernier caliper is being
used in the industry for
measuring the dimensions of
the job. A vernier scale is a
visual aid that allows the user to
measure more precisely than
could be done unaided when
reading a uniformly divided
straight or circular
measurement scale.

20. PROJECT
MICROMETER
Itis a device incorporating a
calibrated screw widely used for
precise measurement of components.
HEIGHT GAUGE
A height gauge is a measuring device used
either for determining the height of objects,
or for marking of items to be worked on

21. CONCLUSION
In our industrial training, we were introduced to
industrial environment. We learned discipline and
cooperation during training & we felt good when we
came in contact with engineers & workers. Most
importantly we had learn the process of doing work in
big work shop with complete knowledge of BULL GEAR
which will be useful for us when ever we go to any
industry or work shop as an employee.
