H.A.L was establised on 1 october 1964 by Seth Walchand hirachand with primary motive of production of Defence and civil aircraft.
H.A.L lucknow ,an accessories division was establised in 1970 with the primary objective of manufacturing systems and accessories for various aircraft and engines .
HAL : SECTION
Whole factory divided into following section .
• Fuel factory
• Mechanical factory
• Instrument factory
This factory is called so because all accessories related from fuel tank to engine are manufactured in this factory .
Fuel factory also divided into following section
• Machine Shop
• Precise Machine Shop
• Lapping Section
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
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
4. tool rest
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.
LATHE MACHINE (Cont)
Operations performed on Lathe machine:
Cutting fluid : Fatty oil or blended fatty mineral oil.
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 .
A Milling machine is used to machine solid materials
Classification of milling machine :
horizontal milling machine
Verticle 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 .
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
In lapping shop ,Surface finishing operations are performed by reducing roughness, waviness, and other
In this shop various machines are there to perform above operation these are Drilling , Boring , Grinder
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
