Problem Statement
A global OEM specializing in diversified industrial equipment encountered three core issues: (1) Component Inconsistency: CNC turned parts and machining parts for aerospace and terminal power equipment failed to meet ±0.005mm tolerance requirements, leading to 12% rework rates; (2) Lead Time Delays: Optical-electrical equipment’s custom connector components required 35-day lead times, delaying final assembly by 18 days on average; (3) Cross-Line Compatibility: Terminal power equipment’s terminal blocks did not align with CNC equipment’s wiring interfaces, causing 8% of assembly defects.
Solution Design
- Standardized CNC Machining Framework
- Implemented 5-axis CNC equipment for high-precision turned parts, with G-code templates aligned across aerospace and terminal power lines;
- Deployed SPC (Statistical Process Control) tools to monitor 12 key dimensional parameters in real time;
- Integrated Quality Control (QC) System
- Added optical measurement equipment (CMM + laser profilometer) for 100% inspection of critical aerospace components;
- Established a closed-loop feedback system between CNC machining centers and QC stations to auto-adjust machining offsets;
- Supply Chain Synchronization
- Collaborated with 3 key suppliers to adopt the standardized CNC machining templates for optical-electrical connector components;
- Created a shared MRP (Material Requirements Planning) platform to align component delivery with assembly schedules;
Implementation & Results
h>Before Implementation h>After 6 Months h>Improvement
| Metric | |||
|---|---|---|---|
| Rework Rate (Critical Components) | 12% | 1.8% | -85% |
| Lead Time (Optical-Electrical Connectors) | 35 days | 14 days | -60% |
| Assembly Defect Rate (Cross-Line Compatibility) | 8% | 0.5% | -94% |
| On-Time Delivery (Final Equipment) | 78% | 96% | +18% |
Key Takeaways
The solution’s success relied on cross-equipment standardization (unifying CNC machining protocols across 5 equipment lines) and data-driven feedback loops (integrating QC and machining systems). This case demonstrates that aligning precision component manufacturing with end-equipment requirements can reduce costs, improve quality, and accelerate time-to-market for diversified industrial OEMs.
