Using FEM calculations, the company has monitored performance under working conditions to ensure that its newly developed CFRP clamping device is ideally loaded and balanced.
As a result, Hainbuch now relies on carbon fibre reinforced plastic (CFRP) as the basis for its new lightweight generation of clamping devices. The manufacturing process sees CFRP embedded in a plastic matrix in multiple layers. The result is a high strength composite material in which strength and rigidity in the fibre direction are much greater than it is transverse to the fibres. The clamping devices have a static radial clamping force of up to 170 kN.
The Hainbuch strategy of utilising CFRP reduces the weight of the clamping device by upward of 70% and results in 30% faster spindle acceleration.
