Machine builders and operators know how easy it is to damage a machining spindle. Tool collision or wrong programming/ settings can often lead to spindle repairs or replacements in a tenth of a second, causing significant downtime and costs. We can now offer a solution with our newly developed aerostatic hybrid bearing technology. In the case of a spindle overload or collision, the shaft does indeed and still touch down on the bearing face, but due to the enormous contact area and a hard-lubricating of the material pair, the shaft, and the bearing faces are not damaged, saving you time and money. Of course, you are going to need a new tool.

Overload and crash trials

In intensive tests, we deliberately overloaded the bearings and the motor of the same spindle (ASD060H25A) several times, causing tool breakage and even collisions with the workpiece.

The results were beyond our expectations: The spindle bearing remained undamaged. We simply had to replace the tool and could continue working with the same spindle. This demonstrates the robustness and reliability of our new aerostatic hybrid bearing system.
