APEC SK Series – 5-Axis High Speed Gantry Machining Centers
The APEC SK Series 5-Axis High Speed Gantry Machining Centers are engineered for high-speed, high-precision machining of aerospace aluminum alloy structures. Featuring APEC’s U-shape gantry structure, linear motor drives, and the industry’s lowest gravity center, the SK Series provides outstanding rigidity, vibration control, and stability in a compact, space-saving footprint. With its ability to achieve ultra-fine surface finishes on thin-walled parts, the SK Series is built to meet the accuracy and speed demands of today’s aerospace manufacturers.
Benefits for Aerospace Aluminum Machining
The SK Series helps Tier 1–3 aerospace suppliers produce complex aluminum components with superior accuracy, surface quality, and throughput. Its rigid U-shape gantry ensures stability during aggressive material removal, while linear motor drives deliver rapid positioning and smooth dynamics. Combined with advanced chip evacuation, the SK Series is designed for continuous high-volume aerospace production with minimal downtime.
