Sinowon Composite Flash Measuring Machine | Full Inspection Solution for Wind Power Fasteners – One-Click Precision Measurement of Thread Major Diameter, Minor Diameter, Pitch & Flank Angle

Wind power fasteners are produced in large batches with extremely high precision requirements. Traditional manual inspection methods are inefficient and prone to human error. Sinowon introduces a composite flash measuring solution for 100% inspection of wind power fasteners, integrating Vision Measuring Machine (OMM) with high-speed flash technology. This system meets all needs for Geometric Dimension Measurement, Video Measuring System capabilities, and optical inspection, completely solving the challenge of measuring critical thread parameters.

1. Challenges in Wind Power Fastener Measurement

Wind power fasteners (e.g., high-strength bolts, nuts, studs) require strict control of:

• Thread major diameter, minor diameter, pitch, flank angle
• Shaft straightness, end surface flatness
• Length, step dimensions, and other geometric dimensions

Limitations of traditional manual inspection:

• Go/no-go gauges provide no quantitative deviation data
• Profile projectors rely on manual targeting – slow operation and high human error
• 100% batch inspection is nearly impossible; only sampling is feasible

Consequence: High risk of defective parts entering assembly, compromising the safety of wind turbine connections.

2. Solution: Sinowon Composite Flash Measuring Machine

Sinowon combines high-precision flash technology with a traditional Video Measuring System (OMM) to create a composite flash measuring machine, specifically designed for high-volume fastener full inspection.

Core Technical Features

• One-click flash measurement: Automatically identifies parts and measures all specified parameters simultaneously
• High-precision optical measurement: Repeatability down to micron level, meeting wind power fastener tolerances
• Dedicated thread algorithm: Automatically fits major diameter, minor diameter, pitch, and flank angle

3. What Can Be Measured (Complete Geometric Dimension Measurement List)

3.1 Key Thread Parameters

3.2 Geometric Dimension Measurement

• Length, outer diameter, inner diameter, step height
• Coaxiality, perpendicularity, position tolerance

3.3 Flatness & Other Form Tolerances

• End surface flatness measurement (flash combined with laser or shadow method)
• Parallelism, roundness

3.4 High-Volume Full Inspection

• Simultaneously measures dozens of small fasteners in a single field of view
• Supports batch measurement with real-time SPC data output

4. Problems Solved

Typical Case:
A wind power fastener manufacturer with daily output of 30,000 parts. After adopting the Sinowon composite flash measuring machine, thread measurement time dropped from 35 seconds to 5 seconds per part. Full inspection became feasible, and defect rate decreased by 62%.
