Ensuring the performance and reliability of measurement instruments, whether portable or stationary, is critical in maintaining accuracy and avoiding costly downtime. Proactive maintenance strategies, such as addressing wear and tear, routine inspections, and timely calibration, ensure that your instruments remain in optimal condition. This blog highlights essential maintenance tips to help prolong the life of your devices and maintain their accuracy over time.
The importance of preventive care
Measurement instruments are sophisticated tools, and even minor issues can affect their performance. While many portable and shop-floor systems are specifically designed to operate reliably in challenging environments, factors like temperature fluctuations, dust, and contaminants can still influence long-term accuracy and stability. Regular, proactive maintenance helps mitigate these effects, reduces the likelihood of unexpected failures, and can lower repair costs. Depending on the product type and operating conditions, maintenance strategies can be tailored to ensure optimal performance and extend the life of the equipment.
Portable devices
Portable devices are built for versatility and mobility—designed to perform reliably in a variety of environments. However, regular use and exposure to different conditions can lead to wear over time. To ensure consistent performance and extend the life of your equipment, Hexagon recommends the following best practices:
1. Clean sensors regularly
Sensors are vital to the accuracy and functionality of many portable instruments. Gently clean the sensors with recommended tools to avoid debris buildup, which can affect readings.
2. Follow storage guidelines
When not in use, always store your device and its computer in protective cases and avoid areas with:
- Excessive heat or freezing temperatures
- High moisture or humidity
- Electromagnetic interference or heavy vibration
3. Frequently inspect cable connections
Loose or damaged cables can lead to incorrect measurements or system malfunctions. Check connections frequently and replace worn cables as needed.
4. Validate performance daily
Perform a quick validation routine at the beginning of each shift using sphere or bar artifacts. This simple 5-minute check helps catch issues early and ensures your device remains within spec. If a validation fails, contact Hexagon service for support.
5. Keep RDS software up to date
Use the Hexagon Universal Updater to ensure your RDS software and related applications (like PC-DMIS, Inspire, or BendingStudio) are always current. You’ll receive a notification in the system tray when updates are available—just click to apply them.
6. Calibration for accuracy
Routine calibration against standardised benchmarks ensures your device delivers reliable results. Use manufacturer-recommended procedures or authorised service providers for calibration services.
Stationary devices
Stationary measurement systems—such as coordinate measuring machines (CMMs)—are engineered for precision, whether installed in metrology labs or on the shop floor. While routine service by Hexagon professionals is essential, there are also daily and periodic checks customers can perform to maintain performance and prevent disruptions:
1. Maintain a clean operating environment
Even in shop-floor settings, minimising airborne dust and contaminants helps support long-term measurement stability. Use protective covers when the device is not in use, and ensure nearby work processes do not generate excessive debris or vibration.
2. Check rail movement
Run the machine through basic movements and ensure the rails move smoothly and consistently. Unusual friction or noise could indicate the need for Hexagon service attention.
3. Clean the device regularly
Wipe down exposed surfaces, especially around moving parts and guideways, to prevent buildup of particles that can interfere with mechanical motion or sensor function.
4. Check the air supply system
For machines using air bearings, inspect the air unit for signs of oil, debris, or damage. Keeping air lines and filters clean helps maintain smooth, precise movement.
5. Inspect probe tips
Examine probe tips regularly for signs of wear, residue, or damage. A compromised tip can affect contact accuracy, leading to faulty measurements.
6. Perform safety checks
Periodically test the emergency stop functions, probe-changing systems, and any interlocks to ensure operator safety and system protection.
7. Keep software up to date
Hexagon’s PC-DMIS software offers multiple updates each year, adding new capabilities and improving system performance. Staying current can boost productivity and measurement reliability.
Keep your equipment at its peak
Staying ahead of maintenance issues means staying ahead of downtime, delays, and rework. Whether you’re working with handheld scanners or shop-floor CMMs, proactive care extends tool life, improves performance, and keeps your operations running smoothly.
Taking care of your tools today means fewer disruptions tomorrow. Start implementing these strategies to keep your instruments in top-notch condition!
