The growth of Indian manufacturing sector depends largely on its productivity & quality. Productivity depends upon many factors, one of the major factors being manufacturing efficiency with which the operation /activities are carried out in the organization. Productivity can be improved by reducing the total machining time, combining the operations etc. In case of mass production where variety of jobs is less and quantity to be produced is huge, it is very essential to produce the job at a faster rate. This is not possible if we carry out the production by using general purpose machines. The best way to improve the production rate (productivity) along with quality is by use of special purpose machine. Usefulness and performance of the existing radial drilling machine will be increased by designing and development of multispindle drilling head attachment. This paper deals with such development undertaken for similar job under consideration along with industrial case study.

Lovely professional university
3. ABOUT THE COMPANY:
DELUX FOUNDARY is the name of the company in which I have
completed my six weeks industrial training. This company is
established in 1969 by Mr. Rakesh Sehdev.
The trade mark of this company is KHALSA BOMB TOKA and
trade Regd. No. is 232820. It is situated on G. T. ROAD, BATALA –
143505 (Pb.) INDIA.
This company is Manufacturer & Exporter of all type lathe
machine, manual driven chaff cutter machines and all type of
agriculture implements.
4. Training work
The designing of all parts of lathe machine is done in Auto cad software.
After the designing the production part comes into play where the bed of
lathe machine is done by C.I casting and gears and apron are made up of
steel. After manufacturing of all parts the assembling is done according to
the drawing. I have also observed that before the installation of lathe
machine how proper testing of soil is done for heavy duty lathe. I also
calculate the dimensions of lathe machine after the production of lathe
machine and observed the difference between the observed value and
technically calculated values. I also came to know the different operating
techniques of the lathe machine and also come to know about the
maintainance of it.
5. LATHE MACHINE
“the mother of entire tool family”.
A lathe operates on the principle of rotating workpiece and fixed cutting
tool.
The cutting tool is feed into the work piece, which rotates about its own
axis, causing the work piece to be formed to the desired shape.
6. HISTORY
One of the oldest and most important machine tools.
In 1569, wood lathe were in use in France.
More demand, manufacturing also started in India.
7. CONSTRUCTION OF LATHE AND PHYSICAL
PROPERTIES OF GREEN SAND:
Basic material
Cast iron: Carbon (1.8-4% ) and silicon (1-3% ).
Physical property Equipment used Range
Moisture content Speedy moisture tester 3-5%
Permeability Permeability meter 50-90 N.A-2
Compatibility Compatibility machine 250-950 g/cm2
8. PROCEDURE IN PREPARATION OF LATHE
MACHINE Floor plan: The floor should be planned properly according to the size of machine.Sometimes for the heavy duty lathe
we have to consider the strength of soil that it has the capability to withstand large casting weight.
Preparation of Greeen Sand Mixture: In mixture of green sand we are adding 92% of green sand, 3-5% water content,
5-7% bentonite powder. We mix all the compostion and thus green sand is prepared.
Preparation of Pattern: After the preparation of green sand mixture then the pattern of green sand is prepared and we
generally used aluminium for making the pattern
Mould Preparation: In preparation of mould we put the pattern into the green sand and then the mould takes the
shape of pattern and after we remove the pattern from the mould.
Cupola furnace: The pig iron along with silicon and manganese is put into cupola furnace where the mixture melts at
12000c temperature.
Pouring of Cast Iron: After the preparation of mould we put cast iron into the runner and we pour until it comes to the
riser.
ASSEMBLING: After preparation of all parts the machine should be assembled properly according the drawing
Grinding and planing: After the solidification the machine is proper grinded with grinder and with the help of planner
we are providing outer finish to it.
Colouring: After completion of all the processes machine is properly coloured and proper primer is applied before
starting the colouring process.
9. . INSTALLATION OF LATHE MACHINE
PLANT LAYOUT:
The floor space should be considered before installation of the machine. The necessary
space for part storage should be left around while selecting space and location for
lathe. Sufficient free space should be left around for the maintainance and overheating.
FLOOR SPACE SELECTION DRAWING shows the plan layout of the lathe machine.
FOUNDATION:
Foundation should be prepared as per the FOUNDATION DRAWING. Depth of
foundation depends upon safe bearing capacity of soil. A firm foundation is essential
for heavy duty lathe machine to ensure the working accuracy.
CLEANING:
Prior to dispatch, all slides, slide-ways, lead screws, rack, end gear train, all bright and
unpainted surfaces are coated with anti-corrosive/ rust preventive. This should be
removed using kerosene or white spirit and wiped dry. Immediately all the bright
machined surfaces should be oiled.
LIFTING:
10. ERECTION:
The machine erection on the foundation should be carefully done. The foundation bolts and
levelling plates should be arranged as per the foundation drawing. Taper wedges should be
used first to obtain the approximate level.
LEVELING
The machine should be levelled accurately to obtain the satisfactory performance. It should be
placed on well laid foundation made according to the foundation drawing. Use precision level
graduated to 0.02mm per metre
12. SAFETY INSTRUCTIONS:
Protect your eyes; wear safety glasses.
Wear shoes with oil Resistant soles.
If you have long hairs tie it back.
Do not wear long sleeved clothing.
Make sure your area is free from chips, coolant and air-hoses or anything
that can be get in your way and cause you to slip or fall.
Care should be taken while removing the part for replacement or repair.
When performing “POWER ON” maintainance or checking of moving
parts, in operation, extreme caution should be taken.
These parts can cause serious injury
13. OPERATING

clamp it at any required angle. A 3600 graduation is in scripted at
the cross slide top to measure the angle compound rest.
The taper wedges and adjustment screw (4), (6) are provided to
adjust the sliding clearance on the slides.
18. BED GAP:
Bed gap provides the extra swing dia of
the machine when it is removed from the
machine. When it is fixed on the bed it
gives the extra length of the slide ways of
the bed near the head stock. When fixing
the bed gap, the resting sheet should be
well cleaned and oiled.
