SIG Large-Format Vision Measuring Machine: Precision Measurement Solution for Aluminum Flanges & Adapter Plates

SIG Large-Format Vision Measuring Machine: Precision Measurement Solution for Aluminum Flanges & Adapter Plates

In high-end manufacturing sectors such as aerospace, new energy vehicles, semiconductors, and automation equipment, aluminum flanges and adapter plates have become the core choice for critical structural components due to their outstanding combination of “lightweight + high precision + corrosion resistance”. Their typical application scenarios include:

• Aerospace – Pipeline/equipment connection flanges that reduce aircraft weight while meeting high-pressure and high-reliability requirements.
• New Energy Vehicles – Connection components for battery pack cooling lines and electric drive systems, balancing lightweight design with heat dissipation.
• Semiconductor & Precision Instruments – Mounting adapter plates for equipment platforms and optical systems, demanding extremely tight hole position accuracy and flatness.
• Automation & Robotics – Connection flanges for robotic arm joints and rotary platforms, reducing moving inertia and improving control precision.
• Chemical & Marine – Certain aluminum alloys (e.g., 5083) resist seawater corrosion and are used for lightweight upgrades of piping systems.

These diverse and demanding applications impose strict geometric dimensional control requirements on flanges and connection plates. SIG’s large-format Vision Measuring Machine, based on Vision Measuring Machine technology and optical dimension measurement principles, is specifically designed for dimension inspection of large-size, high-precision aluminum flanges/adapter plates, providing comprehensive and reliable quality assurance solutions for users across industries.

Technology Explained: Core Advantages of Non-Contact Optical Dimension Measurement

A Vision Measuring Machine (also known as an optical measuring machine) is a high-precision dimensional inspection device based on optical imaging principles. Its core workflow includes: a high-resolution industrial camera captures digital images of the workpiece; specialized measurement software performs image processing and geometric calculations to automatically extract points, lines, circles, arcs and other geometric elements, then calculates dimensions, positions and geometric tolerances.

Compared with traditional contact measurement tools (such as vernier calipers or CMMs), optical Geometric Dimension Measurement offers three major advantages:

• Non-contact, zero damage – Eliminates the risk of scratches or deformation that contact measurement may cause to precision workpiece surfaces, especially suitable for finished or coated flanges.
• High efficiency, fully automatic – Supports CNC programming for one-click measurement; dozens of dimensional data points can be acquired in a single operation.
• Micron-level accuracy, traceable – Measurement data is automatically archived and SPC statistical reports are generated, providing reliable support for process improvement.

What Can the SIG Large-Format Vision Measuring Machine Measure on Aluminum Flanges/Adapter Plates?

Targeting the typical structural features of aluminum flanges and adapter plates, SIG’s large-format Vision Measuring Machine comprehensively covers the following key measurement items:

• Hole Position & Spacing Measurement – Automatically identifies and measures circle diameter, slot dimensions, edge-to-hole distance, center-to-center distance, and multi-hole position error (out-of-tolerance mounting holes directly lead to assembly interference or connection failure).
• Profile & Dimension Measurement – Measures flange outer diameter, inner diameter, thickness, irregular boundary contours, as well as fine features like arc radius, chamfer, and corner radius, ensuring blank dimensions conform to drawings.
• Flatness & Coplanarity Measurement – Through full-field Z-axis height scanning, automatically collects planar feature point data to evaluate flatness deviation of the flange mounting surface, avoiding sealing failure caused by excessive flatness error.
• Concentricity & Position Measurement – Efficiently measures the concentricity of the flange’s center, ensuring the inner and outer circles of the adapter plate are coaxial, guaranteeing smooth rotational assembly.
• Step Height & Level Difference Measurement – With optional laser or probe module, accurately measures step height, thickness uniformity, and counterbore depth of the flange.
• Geometric Dimensioning & Tolerancing (GD&T) – Supports comprehensive geometric measurement including parallelism, perpendicularity, symmetry, straightness, and more.

What Industry Pain Points Does SIG’s Large-Format Vision Measuring Machine Solve?

Pain Point 1: Incomplete Measurement with Traditional Tools – Insufficient Coverage for Large Flanges

Large aluminum flanges or adapter plates exceed the travel range of traditional tools like calipers and feeler gauges, making full-size coverage difficult. Operators often rely on “segment measurement” or manual sampling, leading to high risk of missed defects. SIG’s large-format Vision Measuring Machine uses a moving-bridge or high-rigidity granite gantry structure, with travel up to several thousand millimeters, enabling full-field scanning measurement of entire plates or large flanges in one pass.

Pain Point 2: Inaccurate Measurement with Contact Methods – Thin-Walled Parts Deform Under Force

Aluminum alloy is relatively soft; contact measurement can cause slight deformation under force, making the measured data deviate from the true value. SIG’s large-format Vision Measuring Machine adopts non-contact optical dimension measurement technology – the workpiece is not stressed during measurement, faithfully reflecting its original dimensional state.

Pain Point 3: Low Efficiency in Batch Inspection – Sampling Cannot Guarantee Quality of Entire Batches

Under manual sampling, it is impossible to cover every product in mass production. The risk of defective parts flowing into the next process remains. SIG’s large-format Vision Measuring Machine supports fully automatic CNC programming and “one-click measurement”, enabling 100% full inspection of batch flanges/adapter plates with significantly improved efficiency. Each measurement is automatically archived and supports SPC process capability analysis, providing a complete traceability chain for quality management.

Pain Point 4: Impossible to Measure Complex Structures – Precision Features Exceed Traditional Tool Capabilities

Aluminum flanges/adapter plates often contain complex features such as multiple holes, irregular contours, and small chamfers that traditional measuring tools cannot handle. SIG’s large-format Vision Measuring Machine is equipped with a high-resolution color camera and a programmable 5-ring 8-zone LED multi-angle illumination system, clearly imaging fine workpiece edges, while the intelligent measurement software automatically completes accurate measurement of complex features.
