As a leading CNC machining service provider, AOOM Technology specializes in precision CNC shell machining processes for industries ranging from aerospace to consumer electronics. This article will explore the technical nuances of shell machining and how our expertise delivers unmatched quality.

What Is CNC Shell Machining?

CNC shell machining refers to the subtractive manufacturing process for creating hollow, enclosure-type components with complex geometries. Unlike solid block machining, shell structures require specialized toolpath strategies to maintain structural integrity while achieving thin walls (typically .5-3mm thickness).

Key Process Considerations

1. Material Selection: Aluminum alloys (6061-T6, 7075) and stainless steel (304, 316L) are most common for shell components due to their strength-to-weight ratio.
2. Tooling Strategy: Our 5-axis CNC centers utilize tapered end mills and dynamic milling techniques to prevent vibration-induced defects.
3. Fixture Design: Custom vacuum chucks or expandable mandrels ensure zero deformation during machining.
