Thanks to the fully automatic tool changer with up to 20 different tools and inclusive, independent data management, the machine operator no longer needs to manually fit and remove the tools for profile grinding (including the associated cooling and rinsing nozzles) during the retooling process.
The machine concept comes equipped with a 3D scanning measuring process that determines corrections without the need for an external measuring machine and optimizes the machining parameters in a single work step. The end result is a stable, enclosed in itself process that leads to significantly better grinding results with current profile shape accuracies of +/- 3 μm in practice.
Furthermore, the machine can execute a range of simulations in advance, for example the dressing path and the corresponding diamond wheel geometry as well as the effect of changes to the grinding wheel profile on the workpiece.
Other rotor grinding machines measure the profile and gradient progression of an already-ground workpiece after the workpiece arrives at a measuring machine. The corrections determined on the basis of the measurement protocol are then read in, so that the workpiece can be ground again. This process repeats until the desired result is achieved – a quite costly and time-consuming process which the JUNKER machine eliminates.
