EMAG Automation says its heat-shrink technology provides an assembly process for the manufacture of precision components – in particular composite camshafts. The company says the process is characterised by its reaction force-free processing sequence. The component is brought up to the necessary temperature with great precision, using an inductive or contact heating process..
After that, the warmed up workpiece is joined with the shaft without any application of force. As the workpiece cools, it clamps down firmly on the shaft. A combination of robots, NC axes and gripper technology guarantees a process with a joining clearance of less than 15 micron, claims EMAG. The whole process for camshafts – from pick-up of the relevant components to completion of the force fit action – takes approximately 7 seconds.
