In the realm of metrology, accuracy is not a goal; it is a requirement. At DONGGUAN CITY HANDING OPTICAL INSTRUMENT CO., LTD., we believe that the foundation of any high-quality Video Measuring Machine (VMM) lies in its displacement feedback system. Today, we want to share a deep dive into the technology that drives our precision: optical linear encoders and exposed linear encoders.
When we design a Video Measuring Instrument, the integration of linear scales is the most critical step. Why? Because the software’s coordinate calculations are only as good as the physical data provided by the linear encoders. Our range of optical encoders, including both incremental encoders and absolute encoders, is engineered to provide sub-micron resolution, ensuring that every movement of the Automatic Video Measuring Machine is tracked with surgical precision.
For high-end applications like semiconductor inspection or aerospace component grading, we often utilize exposed linear encoders. Unlike enclosed scales, exposed systems offer higher dynamic performance and eliminate the friction associated with seal lips. This allows our Bridge-type Video Measuring Machine to achieve faster acceleration without compromising on micron-level repeatability.
Our optical linear encoders and angle encoders are not just components; they are the result of years of R&D. By manufacturing our own encoders and rotary encoders, we ensure that the thermal expansion coefficients of the scales match the machine structure. This synergy is what makes a Handing OMM or 3d Video Measuring Machine stand out in the global market.
Beyond the scales, the quality of the optical measuring system is amplified by our high-resolution optics. When combined with our exposed linear encoders, the Video Measuring Systems can perform complex tasks like 3D profile scanning and non-linear error compensation in real-time. Whether you are using a Manual Video Measuring Machine for laboratory work or a Semi-automatic Video Measuring Machine for the shop floor, the reliability of the linear encoders remains consistent.
As a leading Video Measuring Machine Manufacturer in China, we are committed to pushing the boundaries of what is possible in non-contact measuring machine technology. Our commitment to using superior optical linear encoders ensures that every Vision Measuring System we ship meets international standards.
