As manufacturing accuracy standards continue to rise, traditional manual measurements and 2D projectors are no longer sufficient for the fast and stable inspection of complex or high-precision components. The Automatic Vision Measuring Machine (VMM), combining non-contact measurement, high-resolution imaging, auto edge detection, and intelligent software, has become a core inspection platform in modern quality control systems.
This article introduces our latest CNC-type automatic vision measuring machine in detail—from structure and motion control to optical configuration, software, and optional expansions—helping users fully understand its technical value and application potential.
1. Overview: A High-Precision Smart Measurement Platform
This CNC automatic vision measuring machine is independently developed and designed by our company, targeting mid- to high-end manufacturing industries with needs for high-precision, automated, and batch inspection. It is applicable to PCB boards, die-cut molds, smartphone frames, glass, metal parts, plastic components, and more.
2. Core Advantages & Technical Highlights
1. Dual Closed-Loop Motion Control: Accuracy & Stability
The machine adopts a dual closed-loop servo control system for X, Y, and Z axes, integrating high-resolution linear scales and encoders. This ensures precise positioning and smooth motion even during high-speed operation.
Key Benefits:
No missed steps or vibrations during high-speed travel
Repetitive positioning accuracy: ±3μm
Maintains trajectory precision even in complex paths
Example:
When measuring curved contours of die-cut molds, any deviation in movement affects shape accuracy. The dual closed-loop system guarantees pinpoint positioning.
2. Embedded Module Control: Faster Response & Simplified Interface
Our self-developed embedded module integrates motor drive, signal processing, and communication protocols. Only a USB and S-terminal cable are required for PC connection—greatly reducing wiring complexity and failure rate—while supporting remote control and data transmission.
3. Granite Base Structure: Anti-Vibration & Thermal Stability
The base is made of high-density natural granite with excellent damping, low thermal expansion, and high structural stability. This ensures consistent accuracy even during long-term operation or environmental temperature changes.
Structure Advantages:
Surface flatness within grade 0 precision
Corrosion-resistant, wear-resistant
Ideal for micro-parts and ultra-thin materials
4. Infrared Laser Crosshair Positioning: Fast & User-Friendly
To improve usability, the system includes a high-brightness infrared laser positioning crosshair, allowing users to quickly align workpieces—especially helpful when switching parts frequently.
5. Multi-Zone Adjustable Lighting: Adaptable to Any Material
The machine integrates a 48-zone constant-current LED ring light above the stage. Each zone can be adjusted for intensity and angle, depending on material, surface texture, and color.
Lighting Benefits:
Supports contour, oblique, and back lighting
Eliminates glare, shadows, and material-related noise
Improves edge detection and image contrast
6. QuickMeasuring Software Platform: Efficient & Intelligent
Our proprietary QuickMeasuring software supports advanced image processing, automated measurements, batch programming, and statistical reporting.
Main Features:
Auto-detects lines, arcs, holes, grooves, angles, etc.
Supports CAD import for contour comparison
Fast batch execution of programs
One-click SPC report generation
Example:
In PCB inspection, engineers can pre-set dozens of test points for solder pads. The system handles auto edge finding and judgment without human monitoring.
7. 3D Measurement Capability (Optional Probe)
To meet height, depth, and flatness requirements, the machine supports optional RENISHAW contact probes from the UK, with Ø1mm and Ø2mm tip sizes. Used with the QuickMeasuring software, the system can switch between 2D/3D without reconfiguration.
3D Capabilities Include:
Sloped/step height measurements
Automated flatness evaluation
Groove and hole depth detection
3. Application Industries & Typical Scenarios
Industry Applications
PCB Board Pad position, spacing, via diameter
LCD Modules Contour, hole, and offset analysis
Die-Cut Molds Curve tracing, symmetry inspection
Glass/Plastic Edge defect detection, dimensional verification
Metal Stampings Slot size, angle, corner radius measurement
4. Conclusion: A Reliable Tool for Quality Improvement
As digital quality control and factory automation advance, traditional tools can no longer meet the needs for speed, precision, and consistency. Automatic vision measuring machines, with their non-contact, high-speed, and high-accuracy features, are becoming essential tools—replacing projectors, calipers, and microscopes.
Our independently developed CNC-type VMM offers an optimized structure, cutting-edge features, and powerful software, bringing true ease of operation, intelligent measurement, and maximum productivity to your factory floor.
