Why Preventive Maintenance Costs Less Than You Think

In many companies, maintenance is still perceived as an expense, a necessary cost, but one that is difficult to justify to management.

However, on the shop floor, the reality is quite different: it’s not maintenance that is expensive, it’s the lack of maintenance.

The real cost: unplanned production downtime

A robot breaking down in the middle of a cycle is never a minor incident.

It often results in:

• A complete production line shutdown
• Compromised delivery timelines
• Idle teams
• Potential penalties
• Increased operational pressure

And most importantly, it leads to indirect costs that are often underestimated.

Unlike planned downtime, an unexpected failure forces an urgent response:

• Purchasing parts with expedited shipping, with a risk of backorder (BO)
• Rapid intervention by specialized technicians (often at premium rates)
• Reactive troubleshooting, where the priority is to restart operations as quickly as possible, often at the expense of thorough testing

The result: you pay more… just to react.

Preventive maintenance: a strategy, not a cost

Preventive maintenance completely changes the approach. Instead of reacting to failures, you anticipate them.

In practical terms, it allows you to:

• Schedule downtime at the least critical moments
• Replace components before they fail
• Stabilize equipment performance
• Extend the lifespan of your robots

You move from a reactive mode to a proactive one, and that difference is significant.

The impact on your equipment

Industrial robots are designed to be reliable and high-performing.

However, like any mechanical and electronic system, they require regular maintenance, including:

• Lubrication
• Axis inspection
• Calibration
• Inspection of critical components

What we see on the field at Revtech

When a failure occurs during production, everything shifts into emergency mode. Teams are under pressure, decisions must be made quickly, and the objective becomes clear: get the line running again as fast as possible.

Technicians must act quickly to restore operations, which often reduces the time available for complete validation and testing.

In contrast, with preventive maintenance, everything is controlled:

• Analysis time is planned
• Testing is thorough and rigorous
• Interventions are carried out without pressure

The result: better decisions, more durable interventions, and significantly more reliable equipment.

A preventive approach to optimize reliability and total cost of ownership

Preventive maintenance should be viewed as a key component of an equipment reliability strategy, not as a simple cost center.

From both a technical and economic standpoint, unplanned downtime introduces significant variability into operations, forces interventions under degraded conditions, and increases the risk of secondary failures. It also contributes to a higher total cost of ownership (TCO).

Conversely, a structured preventive maintenance approach helps maintain equipment in optimal operating conditions, anticipate wear on critical components, and optimize maintenance cycles. It reduces operational risks while minimizing production losses.
