1. MANAGEMENT

Management can be defined as a work of art to implement the planned and implemented in a

systematic, organized have certain guidelines. The verb manage comes from the Italian

maneggiare (to handle: especially tools), which in turn derives from the Latin manus(hand).

The French word mesnagement(latermnagement) influenced the development in meaning of

the English word management in the 17th and 18th centuries.

Referring from the Wikipedia Free Encyclopedias, management consists of directing and

controlling a group of one persons or more persons or entities for the purpose of coordinating

and harmonizing the group to achieve a goal. It also includes resources-human resources,

finance, technology and natural resources as well. Management can also refer to a person or

group of persons who exercise managerial functions.

2.1 IMPORTANCE OF MAINTENANCE

Maintenance is an important factor in quality assurance, which is another basis for the successful

competitive edge. Inconsistencies in equipments lead to variability in product characteristics and result in

defective parts that fail to meet the established specifications. Beyond just preventing break downs, it is

necessary to keep equipments operating within specifications (i.e. process capability) that will produce

high level of quality.

Good maintenance management is important for the company cost control. As companies go in for

automation to become more competitive, they increasingly rely on equipments to produce a greater

percentage of their output. It becomes more important that, equipments operate reliably within

specifications. The cost of idle time is higher as equipment becomes more high-tech and expensive e.g.

NC/CNC machines and robots.

Dependability of service is one of the performance measures by which a company can distinguish

itself from others. To establish a competitive edge and to provide good customer service, companies must

have reliable equipments that will respond to customer demands when needed. Equipments must be kept

in reliable condition without costly work stoppage and down time due to repairs, if the company is to

remain productive and competitive.

Many manufacturing organizations, particularly those with JIT (Just-In-Time) programs are

operating with inventories so low that, they offer no protection in the event of a lengthy equipment

failure. Beyond the cost of idle equipment, idle labor, and lost ales that can result from a breakdown, there

is a danger of permanently losing market shares to companies that are more reliable. Maintenance

function can help prevent such as occurrence.

2.1.1 Impact of Poor Maintenance

Maintenance operations include all efforts to keep production facilities and equipments in an acceptable

operating condition. Failure or ml-functioning of machines and equipments in manufacturing and service

industries have a direct impact on the following:

Production capacity:

Machines idled by breakdowns cannot produce, thus the capacity of the system is reduced.

2.1.2 Production costs:

Labor costs per unit rise because of idle labor due to machine breakdowns. When machine malfunctions

result in scrap, unit labor and material costs increase. Besides, cost of maintenance which includes such

costs as costs of providing repair facilities, repair crews, preventive maintenance inspections, spare parts

and stand by machines will increase as machines break down frequently.

2.1.3 Product and service quality:

Poorly maintained equipments produce low quality products. Equipments that have not been properly

maintained have frequent break downs and cannot provide adequate service to customers.

2.1.4 Employee or customer safety:

Worn-out equipment is likely to fail at any moment and these failures can cause injuries to the workers,

working on those equipments. Products such as two wheelers and automobiles, if not serviced

periodically, can break down suddenly and cause injuries to the stress.

3. MAINTENANCE ON PRESS

Everyone have to choose one machine. We have to tell all about the machine maintenance.

I choose Speedmaster SM 74. I will tell all about:

3.1 Maintenance on Printing Unit

3.2 Maintenance on The Entire Press

3.3 Maintenance by Service Technicians


8/24


3.1 Maintenance on Printing Unit

3.1.1 Printing unit - safety instructions

a.

To be observed when working at the press

1. Warning - Risk of injury!When you perform maintenance work, observe all notes on safety contained

in the operating manual.

2. Warning - Risk of injury from rotating rollers and cylinders!When cleaning the rollers and cylinders, the ball of your hand must face the in feed

nip, and your fingers must be directed toward the outlet nip. Select the corresponding

direction of rotation.

3. Warning - Risk of explosion and fire due to dust deposits!Dust, such as powder or paper dust, can pose a risk of fire or explosion. You should

therefore clean the areas affected by dust regularly, at least once a week, using a

vacuum cleaner. Only use suitable and approved industrial vacuum cleaners and

avoid working with compressed air, as this could swirl up the dust.

b. Washing fluid container1. Warning - Risk of explosion from evaporating solvent!

Fill the washing fluid container carefully and only with approved cleaning agents.

Do not overfill the washing fluid container. Keep sources of heat away from the

washing fluid container. Dispose of any leaked substances immediately and in the

correct manner.


9/24


2. Warning - Risk of injury from cleaning agents escaping!The washing fluid container is under pressure. This pressure can lead to washing

fluid being sprayed out of the container. Close the compressed air supply hose and

deaerate the washing fluid container before opening the lid.

c. Blanket cylinder and plate cylinder1. Warning - Risk of injury from rotating rollers and cylinders!

Use the gap cover of the blanket cylinder and/or plate cylinder to avoid injuries.

d. Inking unit1. Warning - Risk of injury from rotating ink fountain roller!

Be careful with the rotating ink fountain roller when working on the ink fountain

when it is engaged or swung down. Clean the swung-down ink fountain only when

the ink fountain roller is at standstill.

e. Numbering device1. Warning - Risk of injury from rotating rollers and cylinders!

Only operate the numbering inking unit with the wash up tray in place. The wash up

tray prevents access to the rollers.

CONCLUSION

Based on this assignment, i had known how important maintenance management in printing

industry. Not only to prevent breakdown, it is necessary to keep equipments operating within

specifications (i.e. process capability) that will produce high level of quality. Good maintenance

management is important for the company cost control. As companies go in for automation to become

more competitive, they increasingly rely on equipments to produce a greater percentage of their output.

The importance of an effective maintenance program cannot be overlooked because it

plays such an important role in the effectiveness of Lean manufacturing. As in personal health

care insurance, maintenance may be considered the heath care of our manufacturing machines

and equipment. It is required to effectively reduce waste and run an efficient, continuous

manufacturing operation, business, or service operation. The cost of regular maintenance is very

small when it is compared to the cost of a major breakdown at which time there is no production.
