Solutions for cost-effective and high-quality machining of aerospace wings
The main challenges for machining these types of structural components are hole making, edging and surface machining.
Tooling solutions for aerospace wings
Composite solutions – product offer for composite machining
Machining solutions dedicated to specific composite materials as well as operations and demands are becoming an increasingly important competitive factor.

Ball-end scanning vs Sturtz
32 mm (1.260 inch) diameter tools used with the same cutting data.
| 32 mm ball | 32 mm Sturtz | |
| Surface speed, m/min (ft/min) | 2,011 (6598) | 2,011 (6598) |
| RPM | 20,000 | 20,000 |
| Feed/tooth, mm/min (in/tooth) | 0.12 (0.005) | 0.12 (0.005) |
| Table feed, mm/min (in/min) | 12,000 (472.441) | 12,000 (472.441) |
| No. of flutes | 5 | 5 |
| Step over, mm (in) | 3.52 (0.139) | 11 (0.433) |
| Pass/sq meter | 284 | 91 |
| Time for 1 sq meter | 23.7 | 7.6 |
| Over 3 times faster generation of surface |
Smaller ball-end tools are typically used, resulting in even greater productivity when switching to Sturtz techniques.
