In the world of precision engineering, accuracy is not just a goal; it's the foundation upon which quality and reliability are built. At DONGGUAN CITY HANDING OPTICAL INSTRUMENT CO., LTD., we understand that a Video Measuring Machine (VMM) is more than just a camera and a stage. It's a sophisticated synergy of optics, mechanics, electronics, and software. As a leading Video Measuring Machine Manufacturer in China, we want to take you beyond the surface-level specifications and explore the core technologies that define a truly superior Vision Measuring System.

1. The Soul of the Machine:

The Optical System The journey of measurement begins with light. The quality of a Video Measuring Instrument is fundamentally tied to its optical capabilities.

Telecentric Lenses: We equip our VMM and OMM (Optical Measuring Machine) units with high-resolution telecentric zoom lenses. Unlike conventional lenses, telecentric lenses eliminate perspective errors, meaning the magnification doesn't change with the distance from the object. This is critical for accurate 2D and 3D Video Measuring Machine applications, ensuring that the edge of a feature is measured correctly regardless of its height.

Intelligent Illumination: Simply seeing a part isn't enough; you must illuminate it correctly. Our Automatic Video Measuring Machines feature multi-zone, programmable LED ring lights, coaxial lights, and contour lights. This allows the system to create optimal contrast for any feature, from a shiny metallic surface to a transparent plastic edge, overcoming challenges like glare and shadows.

2. The Backbone of Precision: Encoders and Motion Control

If optics are the soul, the motion control system is the backbone. The precision of the stage movement directly translates to measurement accuracy.

The Power of Optical Linear Encoders: At the heart of our motion systems are our very own high-precision optical linear encoders. Unlike some manufacturers who source third-party components, we design and produce our own linear scales and encoders. These incremental encoders provide exceptional resolution and thermal stability. Our exposed linear encoders are engineered for durability and resistance to workshop contaminants, ensuring that our Bridge-type Video Measuring Machines and Manual Video Measuring Machines maintain their repeatability and accuracy over years of use. This core competency in optical encoders sets us apart.

Granite Structure & Precision Mechanics: We build our machines on a foundation of high-grade granite. Its low thermal expansion coefficient and excellent vibration damping properties provide a supremely stable platform for the X-Y-Z axes, which are driven by precision ball screws and servo motors for smooth, fast, and precise positioning.

3. The Brains of the Operation: Measurement Software

Powerful hardware is only unlocked by intelligent software. Our software transforms raw data into actionable insights. It's the brain that makes our non-contact measuring machine a smart inspection solution. The software for our 2D Video Measuring Machine and 3D Video Measuring Machine is designed for intuitive operation, featuring powerful edge detection algorithms, automatic feature recognition, and robust reporting capabilities that can be easily integrated into your quality control workflow.
