Case 1	Details
Typical Workpiece	5G Communication Base Station Cavity Filter Material: 6061 Aluminum Alloy Dimensions: Φ480 × 120 mm
Customer Challenge	1.Multi-turnover clamping with cumulative positioning error of ±0.05mm, failing to meet the requirement of sidewall perpendicularity ≤0.02mm to the base. 2.Poor chip evacuation in deep cavity machining caused tool chipping, with up to 8 tool changes per piece. 3.Surface roughness Ra3.2 on profiled curved surfaces required secondary polishing; cycle time ~65 min/piece.
Solution	ZH-500U 5-Axis Machining Center • Φ500mm trunnion rotary table enabling 5-axis simultaneous machining, completing all processes in one clamping. • 20000rpm BBT40 electric spindle + 20kW high-power motor balancing high speed and cutting rigidity. • ±3" A/C axis repeatability ensuring consistency in complex curved surface machining. • Dual high-pressure water pumps solving chip evacuation challenges in deep cavities.
Results	• Eliminated turnover clamping; cumulative positioning error controlled within ±0.012mm, sidewall perpendicularity compliant. • Tool change frequency reduced to 2 times/piece, lowering tool consumption cost by 60%. • Surface roughness improved to Ra0.8, eliminating secondary polishing. • Cycle Time: Reduced to 38 min (Efficiency increased by 42%). • Quality: Yield rate improved from 82% to 96%.

Case 2	Details
Typical Workpiece	Aerospace Engine Impeller Material: Titanium Alloy TC4 Dimensions: Φ350 × 150 mm
Customer Challenge	1.Easy deformation of thin-walled blades; insufficient dynamic response of existing equipment caused obvious chatter, with blade profile deviation exceeding 0.03mm. 2.Low 5-axis linkage accuracy led to poor consistency between adjacent blade profiles, with batch yield rate only 75%. 3.Frequent downtime for inspection required; cycle time ~120 min/piece.
Solution	·Lynuc 5-axis system with look-ahead preprocessing, paired with DDR direct-drive rotary table for high-precision 5-axis linkage. • ±6" A/C axis positioning accuracy ensuring blade profile consistency. • Yaskawa dual-drive Y-axis + Z-axis servo motor with brake enhancing dynamic response stability.
Results	• Chatter completely eliminated; blade profile deviation controlled within ±0.01mm, inter-blade consistency error ≤±0.005mm. • No frequent downtime for inspection; cycle time reduced to 78 min (Efficiency increased by 35%). • Yield rate improved to 94%, with per-piece processing cost reduced by 28%.
