INDUSTRY REQUIREMENTS WORKPIECES WITH THE HIGHEST DEMANDS Only demanding workpieces and components are known in the aerospace industry. Whether geometry and dimensions, materials or dimensional tolerances – the requirements are more stringent than anywhere else. This also has an effect on component machining. In many cases, the only way to achieve the desired result is with customized clamping solutions. The following pages show selected examples. LIGHTER THAN USUAL MORE PRECISE THAN USUAL CHALLENGING MATERIALS Aircraft and spacecraft are lightweight The fact that aerospace technology Special...

INDIVIDUAL SOLUTIONS TURBINE SHELL TASK: Low-deformation clamping for turning and milling SOLUTION: Power-operated diaphragm chuck FEATURES: very low clamping force (approx. 10 kN) central workpiece stop twelve hydraulically actuated support elements additional minimization of workpiece deformation by means of centrifugal force counterweights workpiece dampening to minimize vibration repeat clamping accuracy of less than 0.005 mm adjustable concentricity (concentricity inaccuracy of less than 0.03 mm) TURBINE BLADES TASK: COOLING PLATES IN THE TURBINE AREA Clamping of different workpieces in...

CHALLENGE: ENGINE COMPONENTS 3 Workpieces for engine components pose a particular challenge. They are demanding not only because of their special geometries, but also because of the materials. In the high temperature section of the engine in particular, the workpieces are made of special alloys. Machining is difficult and dangerous internal stresses can build up in the workpiece – risking fracture or failure! Mitigating such risks is one of the challenges of aerospace clamping technology. REDUCTION GEAR The turbofan at the engine intake is It is located behind the fan rotor and The asymmetrically...
