For the mechanical post-processing of fiber composite components with large CNC machines, individual clamping devices are required. This is particularly challenging in the aviation industry, as the fixture has to be replaced after each processing due to the batch size of 1 production. This often leads to long downtimes of the CNC machine, as cleaning, fixture changes and component clamping take a lot of time.
A new clamping concept for two similar components can significantly reduce this problem. As can be seen in the picture, the clamping surface consists of contour-milled aluminum blocks that support around 90% of the component surface. After machining, all plates can be turned 180° simultaneously by simply turning a handwheel. On the back, the blocks are milled to match the geometry of the second component, so that this can also be clamped without any problems.
This system significantly reduces the changeover times of the device, which leads to a considerable increase in productivity.
