HAL:SECTIONIONAL LAYOUT

Whole factory divided into following section .• Fuel factory• Mechanical factory• Instrument factory • SU-30 MKI

21/04/2023 8

MECHANICAL FACTORY This factory consists of various machines which are used to manufacture different assembly parts. Mechanical factory also divided into following sections: -• Machine Shop• Tool Room• Lapping Section

21/04/2023 9

MACHINE SHOP Here rough shape is given to raw materials . Machines available in machine shop are:• Simple Lathe machine• Electric discharge machining• Wire cut EDM• Milling Machine

21/04/2023 10

SIMPLE LATHE MACHINE A lathe  is a machine tool which rotates the workpiece on its axis to perform various operations such as cutting ,drilling or deformation with tools that are applied to the workpiece to create an object which has symmetry about an axis of rotation . Important Parts of lathe machine are 1. Headstock 2. tailstock 3. spindle 4. tool rest 5. Bed

21/04/2023 11

LATHE MACHINE 1. Head stock : The headstock often contains parts to convert the motor speed into various spindle speeds. 2. Tailstock : It is a sliding part opposite to head stock and is used to support job while turning. 3. Spindle : Spindle is a rotating component which hold the job during machining operation. 4. Toolrest : It hold the tool. 5. Bed: Lathe bed is a horizontal beam on which all above parts rest.

21/04/2023 12

LATHE MACHINE (Contd) Operations performed on Lathe machine:• Cutting • finishing• turning • drilling• knurling Cutting fluid : Fatty oil or blended fatty mineral oil.

21/04/2023 13

TURNING SHOP• It is a shop where all type of turning operation on the job are done .• Operations performed in turning shop are:Turning ,Facing ,Grooving , Boring and Threading etc.• Types of machines in TURNING SHOP. NH-22 Center Lathe NH-26 Center Lathe

EDM(ELECTRIC DISCHARGE MACHINE)

EDM is a electric discharge machining which is used for hard metals or those that would be impossible to machine with traditional technique .

Limitation of this machining is only electrically conductive materials can be machined.

It removes material by  series of rapidly recurring current discharges between two electrodes .

21/04/2023 16

WIRE CUT EDM• The wire-cut type of machine arose in the 1960s for the purposeof making tools (dies) fromhardened steel.• The tool electrode in wire cutEDM is simply a wire.• A wire-cut EDM machine using the CNC drawing plotter and optical line follower techniques that was produced in 1974.

21/04/2023 17

MILLING MACHINE A Milling machine is used to machine solid

materials Classification of milling machine : Horizontal milling machine Vertical milling machine In milling machine spindle holds the cutting tool called milling cutter . Operation performed in milling machine are : Slot and keyway cutting, planing, drilling .

TOOL ROOM It is the space where tools are made and

repaired for use throughout the rest of the factory.

There are certain machines to manufacture the tools according to the requirement.

A tool room is everything related to tool-and-die facilities and methods, in contrast to the factory floor and production line activity.

LAPPING SECTION• In lapping shop ,Surface finishing

operations are performed by reducing roughness, waviness, and other irregularities .

• In this shop various machines are there to perform above operation these are Drilling , Boring , Grinder machines .

CERTIFICATIONS The ISO 9001 for entire range of products

and services. ISO 14001 for Environmental Management

System. Approval for Research and Design Centre

by Department of Science and Technology, Govt. of India.

Approval of Director General Aeronautical Quality Assurance for Military Aviation Products and Services.

CONCLUSION After four week of my training ,I found that H.A.L is a leading manufacturer of fighter planes and they also work with new technology . H.A.L Lucknow accessories division makes different product which are needed in planes . For better performance ,the formed product are sent to quality control department .the product are properly checked then they are sent for assembly.
