Auxiliary Spindle

Project description
In order to produce several bearing bores in a stator component, an auxiliary spindle should be developed for an existing portal milling machine. A special requirement for the construction was the highest possible flexural rigidity, which should guarantee consistent manufacturing accuracy with maximum workload.

Due to the special design, the manufacturing accuracy could be increased and the manufacturing time as well as the costs per workpiece could be reduced. The auxiliary spindle can be used in the existing tool change system of the milling machine. In this way, in connection with the high possible workload of the spindle, the processing time of customer orders could be reduced significantly and is more economical. The investment is refinanced at short notice.
