What is Machine Inspection?

Machine inspection plays a key— yet often overlooked — role in a complete and effective uptime-focused strategy. In this context, you may ask, “What is machine inspection?”

As a dedicated practice, machine inspection refers to scheduled, purposeful, proactive equipment checks that are carefully designed to identify possible issues and forecast necessary maintenance needs. By gauging machine health at regular intervals, the facility is able to address potential issues more quickly, reduce unplanned maintenance events, and more effectively plan for inventory and MRO needs.

Ignoring the importance of machinery inspections can lead to several negative consequences.

These may include:

  • Increased unplanned downtime
  • Reduced service life of equipment
  • Excessive costs for emergency repairs and parts
  • Inefficient and unsafe equipment operation

Machine Inspection, Explained

Here, we will introduce the tasks that play a part in machine inspections, the personnel who should perform inspections and recommended intervals for inspection scheduling.

What Does Machine Inspection Entail?

Inspections may comprise a range of tasks for equipment, facilities and applications. In general, a basic equipment inspection should involve the following:

  • A task list or checklist based on a defined strategy or intent for the inspection
  • An overall visual inspection of machine functionality and components
  • A safety check, including failsafe functionalities
  • Operation observation
  • Wear assessment
  • Recommendations for near-, mid- and long-term maintenance steps to address needs identified during the inspection
  • Scheduling of any immediate maintenance tasks recognized during the inspection
  • Documentation, including an inspection summary and report

As you can see, machinery health inspection should not be treated as an ad-hoc task or one carried out when it is convenient. By treating inspections as part of an overall maintenance strategy, manufacturers are much better positioned to increase productivity and eliminate unplanned downtime— which we will discuss later in this article.

Who Performs Inspections?

Inspections should be performed by trained, certified individuals with expertise in the field. An understanding of the equipment at hand, the processes, and applications it is used for, and the goals and objectives of the facility are key to complete effective inspections.

Note that while basic inspections can be carried out by equipment operators as part of everyday maintenance checks, it is important that machine inspections be conducted with the intent of a purposeful maintenance strategy — as illustrated by the depth of the tasks listed above.

When Should Machine Inspections Occur?

Comprehensive equipment inspections should occur at least once a year. In most cases, a twice-yearly inspection will yield tangible maintenance benefits that can justify the cost. As mentioned above, machine health inspections should not be considered the same as standard everyday preventive maintenance tasks performed within the facility. Equipment inspection is a detailed task with specific goals and targeted results.

Benefits of Machine Inspection

Regular machine inspection can yield a range of benefits for your facility. These would include:

  • Increased reliability: With regularly scheduled health inspections, you will be better positioned to identify potential equipment issues, allowing you to address them and plan for them more efficiently and effectively. This proactive approach can lead to fewer equipment breakdowns and an overall reduction in unplanned downtime, increasing the reliability metrics of your equipment.
  • Higher output quality: When equipment is regularly inspected and maintained, it will operate at peak performance more consistently — leading to an overall improvement in product quality, a reduction in part defects and rejects, and a reduction in rework and wasted effort and material.
  • Greater insight into maintenance and repairs: A machine health inspection strategy will allow inspection personnel to have a better understanding of each individual piece of equipment, developing a deep knowledge of the unique aspects and quirks of a machine. In addition to generating more data points by which to plan your maintenance and repair needs, this strategy can provide the intangible benefits of reliable gut feelings about maintenance and performance.
  • Longer machine life: When equipment is inspected and maintained according to a plan, it is less likely to break down or incur damage as a result of maintenance issues. The proverbial “well-oiled machine” should operate as expected for a much longer service life when it is part of a health inspection strategy.
  • Increased employee safety: When maintenance requirements go unnoticed or unheeded until they become a major issue, the safety of equipment operators and facility personnel is at risk. Equipment breakdowns can create danger for the immediate area as well as the facility. Facilities that employ regular equipment health checks may often see an increase in employee safety, as well.
  • Reduced maintenance costs: The investment in a machinery health inspection strategy will almost always pay itself back with dividends — reducing unexpected downtime, decreasing the need for costly emergency repairs and part orders, extending equipment service life, and improving inventory ordering and efficiency.

Who Benefits from Machine Inspection?

Machine inspection can benefit any manufacturing or industrial facility. While expertise in equipment health inspections can be tailored across industries, applications and manufacturers, some of the industries where these services can be most effective are:
