5. INTRODUCTION
It is a process of repairing of machines
Increase availability of a system
Keep system’s equipment in working order
In maintenance include servicing, repair,
modification, overhaul, inspection and condition
verification
6. Important of Maintenance
To maintain the accuracy of machine
To prevent the danger which come in account by
sudden breakdown of any part.
For the safety of operator.
To maintain the efficiency of machine
To keep running the machine continuously without
only broke- down etc.
7. Maintenance in Service Industry
Hospital
Restaurants
Transport companies
Banks
Hotels and resorts
Shopping malls / retail
Gas station
10. Breakdown
Break- down maintenance is done when the
machine stop suddenly due to sudden breakdown
during the operation. In this type of maintenance
only those parts are replaced which breakdown
during the operation. This type of maintenance
takes less time.
11. Preventive
This type of maintenance is done to prevent the
machine from breakdown maintenance. In this
maintenance every machine is tested and repaired
after a fixed period either it faults or not.
Lubrication of machine is done at every part.
12. Reconditioning
Only old machines are taken in field of
reconditioning complete machine is dissembled
and different faults are repaired. The old parts are
changed by new parts and those parts which can
be repaired by some operations they are repaired
on the machines and then fixed at right place.
Lubrication of machine is also done. After all these
process machine is assembled and tested.
14. 1. Disassembly
In every type disassembly is maintenance is little
change. Disassembly of the machine depends upon
the type of maintenance
(a) In break down – In this maintenance only those
part are disassembled which are damaged and
other part are not touched
(b) Preventive – In this type of maintenance all parts of
machine is disassembled after a fine time either
those are damaged or not.
15. (c) Reconditioning – This type of maintenance
dissemble of machine is same as preventive
maintenance but if’s done anytime. This
maintenance is done only with old machine.
16. 2. Washing
After the process of disassemble washing process
in done for washing purpose kerosene oil is used
every disassembled part is washed.
17. 3. Fault Finding
After washing the disassembled part fault is
finding and try to remove it if it is not possible to
remove it then those part is changed.
20. LUBRICATION OR OILING
Lubrication is very important process of maintenance. For
every work other lubricant is used. Some lubricant which
are used for lubrications is follows :
Spin - 5
Viscosity – 5
Used In – Grinding Machines, Wheel Head, Work Head.
Spin – 12
Viscosity – 12
Used In – Spindle on high speed when clearance is 10
microns.
21. Spin - 32
Used In – Hydraulic Machines, Column, Gear box, Milling
machine, Cutter lubrication.
Spin - 68
Used In – Lubrication of Grinding Machine, Hydraulic

Flushing Oil
Used In – When the machine parts are cleaned then its all
oil is taken out and flushing oil is filled for oil level for 2 to
3 days. By this process all corners are cleaned.
