Ultra-precision finishing automation
A major Korean power-equipment maker · Gas-turbine blade surface finishing (polishing) process

A blade finishing process that ran at one piece per person per day had to scale to 12 pieces a day through automation—without giving up micrometer-level quality. We unified and learned every quality-affecting variable—finishing RPM, force, and speed, robot motion, coating thickness, ambient temperature and humidity—to build an operating brain that derives the optimal settings for each model.
- Manual process capped at 1 piece/day
- Finishing quality depended on operator skill
- No process data, so root causes couldn’t be traced
- Five heterogeneous systems turned into nodes with Canal Builder
- AI Agent recommends optimal settings per model
- Analysis and reporting fully completed within the air-gapped network
- 12× productivity gain (1 → 12 per day)
- Operator-independent, consistent finishing quality
- Data turned into assets, supporting manager decisions
