DONGHA Selects TIMI After Comprehensive Validation
The Optimal Driveshaft Solution for Full On-Line Inspection
DONGHA, a well-known driveshaft manufacturer in South Korea, previously purchased a high-end metrology system from a major European brand for laboratory inspection. As the company expanded production and sought to implement full on-line inspection on the shop floor, they conducted multiple rounds of testing and technical validation. After thorough comparison, DONGHA selected USDV’s TIMI automated rotational imaging metrology system.
TIMI delivers high speed, high accuracy, shop-floor deployability, and fast service response—advantages that ultimately earned recognition from Hyundai Motor Group following site evaluation and demonstration.
Challenges
Before adopting the TIMI system, DONGHA faced the following issues:
- Laboratory-type systems could not be deployed on the shop floor for full on-line inspection:The existing system was built for lab use and lacks the durability needed for near-line inspection under oil mist, vibration, and production floor conditions.
- Long maintenance cycles from international suppliers:Repairing European brand equipment often took weeks or even months, disrupting production and driving up costs due to delayed support.
- Difficulty integrating measurement data into digital systems:Existing platforms lack native support for Industry 4.0 workflows—such as automated loading, robotic integration, measurement databasing, and ERP/MES connectivity.
Solution
After multiple rounds of TIMI trial measurement, cross-validation, and performance comparison, DONGHA officially purchased the TIMI6090P system, deploying it directly on the shop floor for full driveshaft inspection.
TIMI provided three core advantages:
1. High-speed metrology system designed for shop-floor deployment
- Completes full-dimension measurement—including runout, concentricity, cylindricity, diameter, and segment height—in 30–40 seconds, supporting shafts up to 900 mm in length.
- Built with anti-vibration and anti-oil-mist design for true production-line use.
- Achieves repeatability better than 0.5 μm through telecentric optical imaging.
Significantly increased inspection efficiency—enabling 100% in-line inspection
- No need to send parts to the laboratory.
- Real-time feedback of process variation to upstream machining.
- Supports rapid changeover and flexible measurement scripting for multiple product types.
Fast support and maintenance response
- Remote support for troubleshooting, measurement consultation, and operator guidance.
- Localized service eliminates long wait times associated with overseas repairs.
Results
Within the first year of deployment, DONGHA achieved the following outcomes:
- Excellent system stability with minimal maintenance effort:TIMI maintained stable performance under continuous shop-floor usage.
- Full on-line inspection for driveshaft production—improving consistency and traceability
- Recognition from Hyundai Motor Group:After seeing one year of successful operation, DONGHA invited Hyundai Motor Group’s affiliated machining plant to visit and evaluate the system.
