How to Keep Your CMM Running Perfectly for Decades

Coordinate Measuring Machines (CMMs) are the backbone of precision manufacturing. They ensure accuracy in aerospace, automotive, medical, and countless other industries. But here’s the surprising truth: with the proper care, your CMM doesn’t just last a few years, it can perform flawlessly for decades. Damon Henrikson, Director of Marketing & New Business Development of Made to Measure Metrology has spent years helping companies protect their investments, and his advice comes down to following a clear set of CMM longevity tips.

“We have high-performing, extremely accurate CMMs here that are 30 years old,” Henrikson explains. “The granite and steel frames could last a century if maintained in a healthy environment.”

Why Longevity Matters More Than You Think

When budgets are tight, some executives see CMMs as disposable tools, an expense to minimize. But the reality is different. A well-maintained CMM isn’t just a piece of equipment; it’s a long-term investment in quality assurance. By protecting your machine, you save on downtime, avoid costly retrofits, and ensure customer confidence in every measurement.

Henrikson points out:

“There’s no reason a recertified CMM shouldn’t last decades. But it comes down to how it’s run. Bad air, poor conditions, or neglect can shorten its life dramatically.”

The Post-Purchase Checklist for CMM Care

Made to Measure has identified several non-negotiables for extending CMM life. These include:

  • Stable temperature: Keep your lab around 68 degrees and avoid wide fluctuations, which distort measurement accuracy.
  • Clean, dry air supply: Eliminate moisture, oil, or dirt that can damage air bearings.
  • Humidity control: Prevent corrosion and premature wear.
  • Proper vibration isolation: Reduce disruptions from CNC machines and heavy equipment nearby.

“Temperature is the big one,” Henrikson stresses. “But vibration can also affect measurement accuracy. We sell isolation pads and advanced vibration systems for facilities with heavy equipment activity nearby.”

Real-World Example: The Midwest Plant

Henrikson recalls a customer in the Midwest who faced chronic vibration problems. Their CMMs sat next to CNC machines, and the vibrations traveled through the concrete floor, affecting accuracy across the entire facility.

The solution started small with basic isolation pads, but for certain areas, the customer invested in advanced vibration isolation systems costing thousands. While the expense seemed steep, it was far less than the cost of inaccurate inspections or machine failure.

CMM Longevity Tips That Pay Off

A CMM that lasts decades provides an enormous return on investment. Compare this with companies that neglect maintenance and end up with “money pit” machines that fail early. Henrikson is passionate about steering customers away from that trap:

“You can adopt basic practices to avoid turning it into a money pit? With proper care, you could have decades of reliable performance instead.”

Another overlooked tip? Don’t pay for more accuracy than you need. Many companies overspend on ultra-precise systems when their parts don’t require it. The smarter move is to buy a measurement device with the right level of accuracy and then maintain it properly.

CMM Longevity Tips: The Bottom Line

Your CMM is one of the most important tools in your quality arsenal. Treating it as an investment rather than an expense pays off in accuracy, reliability, and decades of service. By following these CMM longevity tips, controlling temperature, air, humidity, and vibration—you ensure your machine isn’t just surviving, but thriving.

At Made to Measure, the goal is simple: to keep your CMM running perfectly for decades, delivering the peace of mind and precision your business needs.
