4. INTRODUCTION OF PMTF.
Pakistan Machine Tool Factory (Pvt.) Ltd. (PMTF) is a precision engineering goods
manufacturing enterprise in Pakistan, established in technical collaboration with M/s. Oerlikon
Buhrle & Co. of Switzerland who are the world's renowned manufacturers of Machine Tools.
The factory came into regular production in 1971.
It is located Off National Highway, about 35 Km from Karachi City near Landhi Industrial Estate
and spread over an area of 226 acres out of which 17 acres are occupied by works. The
factory employs about 1900 engineers, technician, workers and other service staff. The layout
of the factory is according to the best European standards. This factory is a unit of State
Engineering Corporation of Pakistan and is engaged in the production of Machine Tools,
Automotive Transmissions and Axles Components, Gears for Locomotives, Pressure Die Cast
parts and other products.
PMTF has rich experience in Designing and Manufacturing of precision engineering goods and
its facilities include Designing, Machining, Forging, Heat Treatment, Assembly, Die Casting
etc.
PMTF is certified to ISO 9001.Quality Assurance System and has excellent Quality Control
and Testing facilities to meet the international quality requirement.

5. DESIGN OFFICE:
In design office we saw various things we saw PMTF standards books like “zero standard
book” in which so many detail about any basic standard of designs and lines and we also saw
a “1 standard book” in which detail description about material and we saw and read other
standards book of PMTF.
We learn how design person work on AUTOCAD software .In PMTF mostly drawings are
converted from one unit to another or we can say that PMTF convert every drawing on PMTF
standards units.
PRODUCTION PLANNING
Production Planning may be said to be a technique of forecasting ahead every step in the long
process of production, taking them at right time and in the right degree and trying to complete
operations at the maximum efficiency.
The production planning department of PMTF consist of three section:
 Cost estimation
 Production pre-planning
 Methodology
Cost Estimation.
The production planning department estimate the manufacturing cost of the product which
includes material cost, rejection cost, forging cast, normalizing cost and machine hour rate.
Production pre-planning.
Production pre planning section prepare the manufacturing lay-out which include all the
operation required to make the final product. Also give the operation instruction O.I where
necessary. Then make the material warrant to issue the material.
Methodology.
Methodology section does the time and motion study to estimate the production time.
Calculate the standard time and obtain time and difference between them.

6. Production control
Production control is the process that keeps a watchful eye on the production flow and size of
resources along with the location, of any deviation from the present action and to arrange for
the prompt adjustment so that the production may run according to the original or revised
schedule.
AREAS OF PRODUCTION CONTROL
Sub-dividing the master schedule into manufacturing and subsidiary orders
 Routing
 Scheduling
 Dispatching
 Expediting
 Inspection
Routing
Routing is determining the exact path which will be followed in production. It is the selection of
the path from where each unit have to pass before reaching the final stage. The stages from
which goods are to pass are decided in this process.
Scheduling
Scheduling is the determining of time and date when each operation is to be commenced or
completed. The time and date of manufacturing each component is fixed in such a way that
assembling for final product is not delayed in any way.
Dispatching
Dispatching refers to the process of actually ordering the work to be done. It involves putting
the plan into effect by issuing orders. It is concerned with starting the process and operation on
the basis of route sheets and schedule charts.
Expediting
Expediting is that branch of production control procedure which regulates the progress of
materials and part through the production process.”

7. Inspection
Inspection is the process of ensuring whether the products manufactured are of requisite
quality or not. PMTF has material testing lab to inspect the material supply by the supplier to
ensure that the material quality (hardness, tensile strength, toughness, etc.) is as per
requirement. Material testing lab also tests the chemical composition of material.
TOOL DESIGN:
Tool design dept. design every new tool and kept record of old tools .Tool design dept. play an
important role in PMTF .They make four types of tools
 Machine tools
 Transmission Tool
 Armaments Tools
 Die casting Tool
Tool design dept. work on these four types of tools and these four types further divided in
many types. PMTF purchase dies from KTDMC. They make design of fixtures, jigs and
gauges, broaching and hoboing tool are purchased from outside.
TOOL ROOM:
Tool Room dept. divided in many sections.
 Milling machines
 Lathe machines
 Sharpen machines
 Grinding machines
 EDM(Electric discharge machine) machine
 Drilling machine
In milling section there are different types of milling machines like shrill machine which is used
to cut the surface, copy milling machine is used to copy the given design form the original copy
generally use to make dies. In lathe section we saw different operation like turning, boring and
facing of tools. In grinding section many types of grinding machines like internal, cylindrical and
surface grinding .In EDM section PMTF has two machines for EDM operation. In re-sharpen
section mostly hob and brooch and tools of lathe and milling machine sharpen. In drilling
section various types of drill machine like simple drilling machine and gang drill machine for
many drilling operation at a time.

8. CNC (computer numeric control):
CNC (computer numeric control) this dept. play a vital role in PMTF, here we make production
quickly and easily. In CNC dept. various types of lathe and milling machine then we saw and
learn the process of making spline on “grob” machine. And then we saw a machining center.
LIGHT PARTS:
Light parts section is generally known to make light parts for the PMTF various operations
have been performed with high accuracy by a skilled and great experienced worker. We saw
different job was being prepared such as head stock of lath machine, Gas meter body,
transmission shaft etc. We had a great experienced.
Light part dept. divided in four sections
 Drilling
 Turning
 Grinding
 Milling
In grinding section, final surface finish of part and achieve accuracy and here also various
types of grinding machine like center hole machine, surface grinding machine, cylindrical
grinding machine. In milling section here various types of milling machines like slotting
machine, face cutter machine and also many machines. In turning section here various types
of turning machines only difference of size of chuck in which part fixed. In drilling section we
learn and saw many terms in drilling like taping, center bore, center sink.

9. HEAVY PARTS:
Heavy parts section deals with the heavy job comparatively than light parts. We had a chance
to see the different machinery working on different jobs including lathe bed, tail stock, carriage
etc.
Heavy part dept. divided in three sections
 Boring
 Drilling
 Planning
In boring section vertical boring machine which moves in x and y axis. In Drilling sections drill
heavy parts and here we saw and learn one more new term reamer. In surface planning
section used shrill milling machines for finish surface and various machines use for planning
operation.
Machine Assembly and Store:
In Machine assembly dept. assemble different parts of machine and after inspection send to
dispatch. Machine assembly dept. divided in different sections like
 Lathe section
 Milling section
 Power saw section
 Paint section
 Drilling section
In lathe section assemble every little or big part of lathe machine and make “C4 lathe” after
assemble go to paint and then final inspection. In milling section assemble milling machine and
make “K4 and K6” milling machine and same operation as lathe section. In power saw section
assemble power hack saw. In drilling section assemble pillar drilling machine.
In this dept. two types of stores
 Those parts manufactured in PMTF
 Those parts purchase outside placed in separate store.

10. SPECIAL MANUFACTURING:
S.M section called SM-300, SM-300 divided in six sections
 SM-302(turning)
 SM-303(drilling)
 SM-304(Milling)
 SM-305(Grinding)
 SM-306(Gear cutting)
 SM-307(special turning)
In this dept. we saw in detail about gears cutting from hob and broaching and different types of
milling machines (square, shrill vertical) and saw many types of drilling machines and also saw
hydraulic press. Gear cutting section have different types of machines gear cutting machines
like (spur, spiral bevel and straight bevel) for both have different machines used .In gear
making there are following process:
 Hobbing process
 Shaping process
 Gear shaving
 Gear grinding
FORGING:
In forging dept. material come outside and burn in furnace make red hot coke, furnace
temperature 1250-1300’centigrade. And then hammering the red coke piece in hammering the
pressure 300PSI and then forging , here in this dept. there are 2 forging machine both apply
different pressure ( one apply 1500 PSI and other apply 300 PSI ) , forging dies different from
other dies PMTF purchase forging dies and after forging cutting rough material , internal
cutting called ”parsing” and external cutting called “Trimming “ after cutting normalizing
material in furnace and if we set temp 925 degree centigrade then normalizing takes 2 hours
and if we set temperature at 650 degree centigrade then normalizing takes 3 hours and in
normalizing process used 5 burners after normalizing material send for short blasting to
remove burn stuff .

11. HEAT TREATMENT:
In heat treatment dept. there are two types of plant old and new in old plant manual working
like in old plant pit type furnace used and arrange charge and after arrange charge in furnace
then check temp then oil quenching and after quenching material testing and check HRC then
send to material testing lab. In new plant sealed furnace in which material after heat treatment
auto directly go for quenching and then come and other process same as old plant then
material send for short blasting to remove the burn stuff and finish the material and after shot
blasting material send for sand blasting and go to dispatch after final inspection.
DIE CASTING:
In this dept. 11 machines for aluminum die casting and every machine make different parts.
Now a days PMTF die casting dept. make SSGC components like G4, G1.6.
G4 have two types of component
 G4 upper case
 G4 bottom case
Other component G1.6, in G1.6 have 4 types of components
 GM body
 Top cover
 Side cover front
 Side cover rear
Now a days these two types of product making in die casting dept. aluminum melt at 660-680
degree centigrade for melting aluminum used natural gas and air pressure. In die casting
machine cover block fixed and ejector block move pump pressure must be greater than 100
psi.
