[Aviation industry] Machining solution to aluminum alloy frame

Industrial Machining Introduction

The integrated structure dominates the main load bearing structure of modern airplanes, which features complex structure, large material removal, accurate and surface quality requirement and long machining cycle. Cutting of these parts has urgent demands for realizing high efficient and correct machining. Main workpiece of the integrated structure is mainly made of aluminum alloy. Xiamen GESAC has mature machining plans for cavity milling, face milling and fine web machining of aluminum alloy structural parts.
