Why do some measuring machines maintain sub-micron accuracy for years while others drift after just a few months? The answer lies in the feedback system. At Dongguan City Handing Optical Instrument Co., Ltd., we believe that the soul of any Video Measuring Machine (VMM) is its displacement sensing technology. Today, we are diving deep into the technical specifications of our optical linear encoders and why they are the preferred choice for high-end Vision Measuring Systems.

In every 2d Video Measuring Machine and 3d Video Measuring Machine we manufacture, the accuracy of the XYZ axes depends entirely on the linear scales. We utilize premium exposed linear encoders that provide real-time position feedback to the controller. Unlike enclosed scales, our exposed linear encoders offer minimal friction and high thermal stability, which is crucial when operating in non-climate-controlled factory environments.

The precision of our incremental encoders and absolute encoders is achieved through high-quality glass scales with chromium gratings. When the reading heads (optical scanners) move along these scales, they generate sinusoidal signals that are interpolated into high-resolution digital data. For our Bridge-type Video Measuring Machine, we use specialized angle encoders and rotary encoders to ensure that even the slightest tilt or rotation is compensated for in the final measurement calculation.

Key technical advantages of our encoder systems include:

1. High Resolution: Our optical encoders can reach resolutions down to 0.1μm, ensuring that your Video Measuring Instrument captures the finest details.

2. High Signal Quality: Our encoders utilize advanced optoelectronic components to ensure high signal-to-noise ratios, preventing data loss during high-speed movements of an Automatic Video Measuring Machine.

3. Durability: Despite being exposed, our linear encoders are treated with specialized coatings to resist oil and dust, ensuring a long service life in industrial settings.

As a leading Video Measuring Machine Manufacturer, we don't just assemble parts; we engineer the core components. By manufacturing our own high-precision linear encoders, we ensure that every Vision Measuring Machine leaving our facility meets the most stringent international standards. Whether you are using a Semi-automatic Video Measuring Machine or a high-speed Optical Measuring Machine, the reliability of Handing's encoder technology ensures your data is always accurate and repeatable.

Understanding these technical nuances helps our clients make informed decisions. When you choose our VMS solutions, you are investing in a system where every component—from the Metallographic tool microscope lens to the optical linear encoders—is optimized for peak performance.
