SIG Vision Measuring Machine: Precision Measurement Solution for Aluminum Precision Plates

In high-end manufacturing sectors such as automotive, electronics, and machinery, aluminum precision plates are critical components due to their light weight, high strength, and corrosion resistance. Dimensional accuracy—including hole position, profile, flatness, and geometric tolerances—directly affects assembly performance and product lifespan. Traditional detection methods are no longer sufficient. The SIG Vision Measuring Machine leverages Optical Measurement and Geometric Dimension Measurement technologies to provide an efficient, accurate, and non-contact solution for the hardware industry.

1. Traditional Measurement Pain Points: Why is Measuring Aluminum Plates Difficult?

Manufacturers face several pain points when inspecting precision aluminum plates:

• Small holes and complex profiles are difficult to measure accurately with calipers or micrometers, leading to high human error.
• Flatness and position tolerances rely on operator experience, resulting in inconsistent inspections.
• Low measurement efficiency in mass production increases the risk of defects. Bad parts moving to the next process cause assembly failures and higher rework costs.

These challenges directly limit the industry’s move toward higher precision, better yield, and smart manufacturing.

2. What Can the SIG Vision Measuring Machine Measure?

The SIG Vision Measuring Machine (OMM) is based on optical measurement technology. Using a high-definition camera and telecentric optical system, it captures and magnifies the part image on a screen. The software automatically identifies and measures the following critical dimensions and tolerances:

2.1 Hole Position & Spacing Measurement

• Round hole diameter and slotted hole dimensions
• Edge-to-hole and hole-to-hole center distance
• Multi-hole position error

2. 2 Profile & Contour Measurement

• External contour length/width and irregular boundaries
• Arc radius and angles
• Small features (e.g., positioning slots, bosses)

2.3 Flatness & Coplanarity Measurement

• Flatness deviation of the aluminum plate surface
• Coplanarity judgment for multi-point support surfaces

2.4 Geometric Dimension Measurement (GD&T)

• Parallelism, perpendicularity, and position tolerance
• Symmetry and straightness

2.5 Other Complex Parameters

• Step height and thickness difference
• Chamfer and fillet dimensions

One single Video Measuring System covers all dimensional control needs, from incoming material inspection and in-process checks to final product testing.

5. Real-World Application Case

An automotive parts manufacturer producing aluminum controller housings required:

• Position tolerance of 12 mounting holes ≤ 0.02mm
• Mounting surface flatness ≤ 0.05mm
• Caliper measurement took 3 minutes/part with a high miss rate.

After introducing the SIG Vision Measuring Machine:

• Full dimension measurement per part: only 15 seconds
• Automatic Geometric Dimension Measurement report output
• Real-time flatness deviation mapping
• Batch defect rate reduced by 60%

6. Future Outlook

With the growth of Industry 4.0 and smart inspection demand, optical measurement devices will evolve from simple measurement tools to quality data nodes linked with automated production lines. SIG will continue to iterate, providing higher-precision measurement solutions for aluminum precision machining, stamping parts, and CNC parts.
