There’s a particular kind of panic that happens when a critical piece of production equipment goes down unexpectedly. Your CMM stops mid-program, your production schedule starts backing up, and suddenly everyone is asking when measurement will be back online. Most of these emergency situations are entirely preventable.
A coordinate measuring machine is sophisticated precision equipment that needs regular attention to continue performing reliably. At Wenzel UK, we’ve spent decades helping manufacturers understand that service contracts aren’t an optional extra—they’re fundamental to protecting your measurement investment and keeping your production running smoothly.
The Real Cost of Deferred Maintenance
The immediate consequence of neglected metrology equipment is loss of accuracy. CMMs can have errors along 21 different measurement axes, and without regular calibration, those errors accumulate. Your machine might still produce measurements, but are they reliable? Can you prove they’re reliable when a customer or auditor asks?
The less obvious consequence is increased downtime. Components wear, bearings degrade, air filtration systems become contaminated, and electronics drift. With proper preventive maintenance, these issues are caught and addressed before they cause failures. Without maintenance, they progress until something breaks—often at the worst possible moment.
We recently worked with an aerospace supplier who had been deferring service on their LH series CMM to control costs. When a critical probe system failed during a first article inspection for a new contract, the cost of that single incident—expedited parts, emergency service call, delayed production, and damaged customer relationship—exceeded what they would have spent on three years of preventive maintenance.
Emergency callouts cost more than scheduled service. Replacement parts needed urgently cost more than parts ordered as planned maintenance. Lost production time and delayed deliveries cost far more than either.
What Proper CMM Service Actually Involves
When we talk about service contracts at Wenzel UK, we’re talking about comprehensive care that keeps your measurement systems performing to specification. Our service engineers follow detailed checklists covering mechanical components, electrical systems, pneumatic systems, and software.
They check all mechanical parts for wear, inspect electrical connections and wiring, verify machine functionality using calibrated artefacts, and examine drive and control systems. Granite surfaces are inspected and cleaned. The float of all three axes is examined. Compressed air systems are verified for proper filtration and drying, because contaminated air damages air bearings over time.
Calibration verifies your CMM against known standards using calibrated artefacts measured in various orientations, proving accurate measurement across the entire working volume. In the UK, proper calibration is typically verified to ISO 10360 standard and supported by UKAS certification, essential for maintaining compliance with quality management systems like ISO 9001, AS9100, or ISO 13485.
All work is documented comprehensively—calibration certificates, inspection reports, and records of adjustments. This documentation is evidence of measurement system capability when auditors, customers, or regulatory bodies ask for proof.
The Windows 10 Upgrade Situation
One of our busiest service activities through 2025 was helping manufacturers upgrade CMM control systems running Windows 10. Microsoft ended support on October 14, 2025, creating security vulnerabilities for CMMs connected to networks.
You can’t simply install Windows 11 on a CMM controller like an office computer. The measurement software needs compatibility verification, drivers need testing, and the entire system requires validation. We worked with dozens of manufacturers to upgrade their systems before the October deadline. Those who planned ahead had smooth transitions. Those who waited often encountered problems.
If you’re still running Windows 10 on your CMM in 2026, this needs addressing. This is exactly the kind of upgrade best handled as part of a service contract rather than as an emergency project.
Controller Modernisation: When and Why
The WENZEL WPC2030 controller has reached end of support, meaning manufacturers with older LH or R series CMMs running these controllers need to plan for upgrades.
A controller is the brain of your CMM. When controller technology is current, you benefit from faster processing, better connectivity, enhanced diagnostics, and compatibility with modern software features. When outdated, you’re limited in capability and increasingly at risk of failures that become difficult or impossible to repair as parts availability diminishes.
We help manufacturers modernize controllers as part of broader retrofit projects. Rather than replace an entire CMM when the granite structure and mechanical systems are still excellent, we update electronics and software to bring the system up to current capability—often the most cost-effective path to extended CMM life.
The key is planning these upgrades as part of your service schedule rather than waiting for failure.
Additional Service Benefits
Contract Measurement Services: At our Coalville facility, we operate contract measurement services with calibrated CMMs in temperature-controlled environments. When your internal measurement capacity is constrained—whether due to maintenance, repair, or capacity limitations—you have qualified backup that can provide UKAS-backed certified results.
Software Care Contracts: Modern CMM performance depends as much on software as hardware. Software care contracts ensure you receive updates and have access to technical support for programming, troubleshooting, or optimizing measurement strategies. Regular communication with our applications team means you’re not just getting updates—you’re getting guidance on how to use them effectively.
Used CMM Availability: We maintain inventory of fully refurbished and certified used CMMs, offering substantial cost savings (typically 40-60% of new equipment cost) while still providing systems backed by full warranty and eligible for service contracts.
Planning for 2026
The cost of a service contract is predictable and manageable. The cost of unplanned downtime, lost accuracy, failed audits, or emergency repairs is neither.
If your CMM is offline, can production continue? Can you ship parts? For most manufacturers, measurement is so fundamental that its absence stops everything else. That makes reliability absolutely critical, and reliability comes from proper maintenance.
Beyond avoiding downtime, service contracts deliver ongoing optimization of your measurement systems. Our engineers bring experience from hundreds of CMMs across different facilities and applications, often identifying opportunities for improved efficiency that wouldn’t be obvious to operators working with a single system daily.
At Wenzel UK, we offer flexible service contract options designed to match different requirements and budgets. Get in touch with our team to discuss service contracts for your metrology systems. Whether you need Windows upgrades, controller modernization, calibration services, software support, or comprehensive maintenance, we’re here to help you plan for reliable measurement through 2026 and beyond.
