Project Background: Precision Restoration Challenge for High-Load Production Lines
The engine production lines of SAIC-GM-Wuling have been operating under long-term high-load conditions. Multiple horizontal machining centers have suffered mechanical wear, accuracy degradation and reduced processing stability, directly affecting the machining quality and production efficiency of core components such as engine cylinder blocks and cylinder heads.To restore equipment precision and ensure stable line operation, the customer urgently required a professional team to carry out systematic overhaul and precision recovery of the horizontal machining centers.
Our Achievements: Remolding Core Equipment Performance Through Professional Overhaul
As the general contractor for equipment overhaul, we adopted a full disassembly inspection strategy, worn component replacement and geometric precision restoration solutions to complete the systematic overhaul of multiple horizontal machining centers, achieving three key breakthroughs:
Full Precision RecoveryAfter complete disassembly and professional repair, the machine tool geometric accuracy and repeat positioning accuracy are restored to factory original standards, with processing stability greatly improved.
One-Time Qualified Quality ComplianceMore than 12 unqualified inspection items under Q-DAS standard were fully optimized to 100% compliance, meeting the stringent quality requirements of mainstream automakers.
Zero Production DowntimeWe adopted a phased alongside-line overhaul mode to implement repairs while maintaining production, maximizing the protection of the customer's overall production capacity.
