How to give wings to machine tool applications

A manufacturer of high-speed cutting and milling machine applications needed to provide specially designed machines to produce gigantic aircraft frames. With the implementation of SKF super-precision bearings, they increased the spindle service life and enhanced their machine tool performance. They are now able to ensure excellent surface quality while providing fast spindle acceleration in different axes.

The challenge: Efficiency and excellent surface quality

Outstanding projects such as the construction of new aeroplanes demand exceptional technology. Huge customised machines are necessary to produce the gigantic frames that later carry the aircraft skin of aluminum. Machine tools must be able to produce excellent surface quality while at the same time creating structural aircraft components with extreme accuracy.

The solution: High-end technology for high-end products

The machine tool manufacturer relied on SKF products and the long-standing experience of our engineers to make the spindles in their machine tools run with the highest speed possible and extremely high accuracy. With SKF customised solutions, such as the super-precision angular contact ball bearings with special (reduced or displaced) tolerances on boundary dimensions, they were able to increase the spindle speed and ensure micrometer-precise customised production.
