Purchasing a high-quality Video Measuring Instrument is a significant investment for any quality department. To ensure that your Video Measuring Machine (VMM) or Vision Measuring Machine continues to deliver micron-level accuracy over years of service, a structured maintenance regime is essential. At DONGGUAN CITY HANDING OPTICAL INSTRUMENT CO., LTD., we believe that "prevention is better than recalibration."

Protecting the "Heart" of the Machine: Optical Linear Encoders The accuracy of any Video Measuring System (VMS) relies heavily on its displacement sensors—the optical linear encoders. These components, including the linear scales and exposed linear encoders, are sensitive to dust, oil, and vibration.

1. Cleaning: For exposed linear encoders, ensure the scale surface is cleaned with specialized lint-free cloths and high-purity alcohol. Any smudge on the optical encoders can lead to signal loss or "counting errors."

2. Alignment: Periodically check the gap between the readhead (reading head) and the scale. Our incremental encoders and angle encoders are designed for durability, but mechanical shifts can impact performance.

Maintaining the Optical Path

The "Vision" in Vision Measuring Instrument comes from its lens and camera. For a Manual Video Measuring Machine or a Semi-automatic Video Measuring Machine, the zoom lens should be operated smoothly. Avoid touching the lens surface. If you are using our Horizontal Instant vision Measuring Machine, ensure the glass stage is free from scratches, as the software uses this surface as the datum for many measurements.

Structural Care for Large-Scale VMMs

For customers using our Bridge-type Video Measuring Machine, the stability of the granite base is paramount. Ensure the machine is installed in a temperature-controlled environment. Drastic temperature fluctuations can cause the granite to expand or contract, affecting the geometry of the Optical Measuring Machine.

Software and Calibration

Accuracy isn't just about hardware. Regularly update your OMM (Optical Measuring Machine) software to leverage the latest compensation algorithms. We recommend a professional calibration once a year using a certified glass master scale to ensure your Video Measuring Machine Manufacturer specifications are still being met.

Summary of Best Practices

Whether you are operating a Desktop instant vision measuring machine or a complex Vertical and horizontal integrated instant vision measuring machine, keeping the environment clean and the linear encoders protected will extend the machine's life significantly.

We provide a full range of spare parts, including rotary encoders, absolute encoders, and replacement linear scales. For technical support or to schedule a maintenance check, please contact our service team.
