Lesson 2 – The system of maintenance activities – purpose and need for maintenance

In this lesson, we delve into the significance and rationale behind maintenance of machinery and equipment.


Introduction to Machinery Maintenance

  • Machinery maintenance has evolved with the machinery industry but varies across time, space, and cultural contexts.
  • It plays a critical role in ensuring the longevity and efficiency of machinery.

Factors Influencing Maintenance

  • Maintenance philosophies differ globally and are shaped by factors like resource scarcity and economic conditions.
  • The development of technology and safety standards is elevating the importance of skilled maintenance professionals.

Aim of Machine Maintenance

  • The primary objective of machine maintenance is to maintain equipment in optimal working condition.
  • Scheduled maintenance is crucial to avoid production downtime, which can increase production costs.

The Need for Maintenance

  • Maintenance is necessitated by the dynamic nature of machinery and materials, where components may require repair or replacement during a machine’s lifespan.
  • Key objectives of maintenance include maximizing productivity, preventing unexpected breakdowns, minimizing losses, enhancing technical reliability, prolonging equipment life, and improving product/service quality.

Impact of Maintenance on Machine Operation

  • The planning and execution of maintenance, including repair technologies and timelines, can significantly affect machine performance.
  • During maintenance, certain technical indicators related to machinery operation may improve.

Collaboration Between Production and Maintenance

  • The activities of production plants are crucial in achieving the desired technical condition of machines.
  • Manufacturers are investing in research and technology to improve product quality, but the post-design phase often receives less attention.

Challenges Faced by Maintenance Specialists

  • Maintenance specialists face complex challenges that demand theoretical and practical expertise.
  • Understanding original objectives and methods for achieving new goals is essential in reviewing maintenance plans.

Diverse Organizational Forms

  • Maintenance can be directly linked to the production company, be a part of a manufacturing company, or operate as a separate entity with its own activities.
  • Environmental concerns are driving the need for equipment that minimizes the disposal of subcomponents and auxiliary materials.

Economic Considerations

  • While it may not be cost-effective to repair certain items like light bulbs, more complex machinery components are often replaced instead of repaired.
  • The decision to repair or replace a machine depends on various factors, including cost-effectiveness and production downtime.


  • Maintenance is a critical aspect of machinery management, impacting both efficiency and economics.
  • Decisions regarding maintenance and machine replacement are complex and depend on a variety of factors.
