For aerospace manufacturers, technical requirements trigger business challenges, including productivity, quality and cost reduction. To increase performance and ensure safety, machine tools must support the entire machining process from cutting parameters to part approval. As a spindle manufacturer, we meet the technical challenges of our customers with dedicated solutions based on our understanding of their needs and desires.

Material challenges

Aerospace manufacturers rely on a range of materials to make parts with varying functions and importance. For example, they use tough Ni/Ti alloys for critical motorization components and lightweight Al alloys for structural purposes, as well as more-exotic, rapidly evolving options such as composites for other applications.

To meet these requirements, we create spindles to provide dedicated solutions: high cutting speeds and continuous high power for aluminum, high power and low rpm for nickel-based alloys and titanium, and our Twin Air Sealing system for composites.
