3. Company Profile
• Stallion Auto Parts Private Limited is a Private
incorporated on 26 April 1995.
• It is classified as Non-govt company and is registered
at Registrar of Companies, Lucknow.
• CEO of Stallion Auto Parts Private Limited is Vijay
Khanna
• It is also one of the few counted names to handle a set
of tier II suppliers to supply parts of sub assemblies,
small sheet metal components, rubber & plastic
components.
• Capable of producing precision prototypes products,
we are specialized in meeting any bulk requirement
within the stipulated time frame.

4. Introduction
• CNC (Computer Numerical Control)
Machines are automated machines, which uses
programs to automatically execute a series of
machining operations.
• CAD (Computer Aided Design) and CAM
(Computer Aided Manufacturing) programs is
used in modern CNC machines for end-to-end
component design.
• Conventionally machines were operated by
skilled technician (operator) who determines the
various variables like speed, feed, depth of cut,
etc. for machining the required component.

5. How CNC Works?
• Controlled by G and M codes.
• These are number values and co-ordinates.
• Each number or code is assigned to a
particular operation.
• Typed in manually to CAD by machine
operators.
• G&M codes are automatically generated by
the computer software.

6. Features of CNC Machines
• The tool or material moves.
• Tools can operate in 1-5 axes.
• Larger machines have a machine control
unit (MCU) which manages operations.
• Movement is controlled by a motors
(actuators).
• Feedback is provided by sensors
(transducers)
• Tool magazines are used to change tools
automatically.

7. Tools
• Most are made from high speed steel
(HSS), tungsten carbide or ceramics.
• Tools are designed to direct waste away
from the material.
• Some tools need coolant such as oil to
protect the tool and work.

8. Basics of CNC Programming
• CNC instructions are called part program
commands.
• When running, a part program is interpreted
one command line at a time until all lines are
completed.
• Commands, which are also referred to as
blocks, are made up of words which each
begin with a letter address and end with a
numerical value.
• Each letter address relates to a specific
machine function. “G” and “M” letter
addresses are two of the most common.

10. • Automated version of a manual lathe.
• Programmed to change tools automatically.
• Used for turning and boring wood, metal and
plastic.
CNC Lathe Machines

11. • Has 3 to 5 axes.
• Used for wood,
metal and plastic.
• Used to make 3D
prototypes,
moulds, cutting
dies, printing
plates and signs.
CNC Milling Machines
10
12. • Slowly removes metal
to create a part.
• Some types of CNC
grinding are
• Surface grinding
• Cylindrical
grinding
• Tool and cutter
grinders
• Profile grinders

13. • Drilling Machines
• Horizontal and Vertical boring machines
• Jig boring and Jig grinding machines
• Plano millers
• Coordinate measuring machines
• CNC welding machines
• Assembly machines
• Printed circuit board drilling machines
• Tube bending machines.
Other types of CNC Machines
12
14. • High Repeatability and Precision e.g.
Aircraft parts
• Volume of production is very high
• Complex contours/surfaces need to be
machined. E.g. Turbines
• Flexibility in job change, automatic tool
settings, less scrap
• More safe, higher productivity, better
quality
• Less paper work, faster prototype
production, reduction in lead times
