Clamping solutions for aerospace industry

With hundreds of thousands of components in an aircraft, Hainbuch gives examples of how interior equipment, frame structures and airfoils, power plant and turbines, as well as the undercarriage can all be precisely and safely clamped.

The new brochure highlights how complex components such as hydraulic valve housings can be internally clamped with Hainbuch’s double independent ID clamping system. Using a mandrel with two independent hydraulic positions and a pull-back effect, the double ID solution incorporates vulcanised segmented bushing to dampen vibration whilst a rigid clamping configuration and optimised chuck body help improve cutting tool access and machining performance. 

For the internal clamping of aerospace parts such as shaft fans that require external milling operations, Hainbuch introduces its segmented bushing chuck. Conducting ID clamping with a dead-length effect for definite radial clamping, the segmented bush chuck can be mounted upon a workpiece carrier for simplified production handling. With full cylindrical surface contact and a large opening stroke between this huge workpiece and the segmented bushing, secure and precise clamping is guaranteed. 

The external clamping product lines from Hainbuch include the segmented mandrel T213 for clamping components such as aerospace turbine gear wheels. The manual hydraulic mandrel has a vulcanised bush and optimised design that maximises the pull-back effect for superior clamping rigidity and precision. Automated loading is made possible by the large clamp and load strokes whilst its quick changeover interface for changing the clamping device in as little as 2 minutes. 

For the external clamping of complex parts such as aerospace bearing journals that require turning operations on the outside features, the Hainbuch TOPlus pull-back chuck offers a solution. The TOPlus technology provides full surface contact between the hexagonal clamping head and the chuck body. The TOPlus provides an inner workpiece end-stop with coolant flush and a chip evacuation channel that ensures prolonged machining.
