In the world of precision machine tools, few topics receive more attention than high-speed machining. Cutting metal at higher speeds increases productivity. But to run faster without losing quality or reliability, the spindle, motor, and bearing system must provide the torque, rigidity, and accuracy for cutting while minimizing rotational friction for the tool and workpiece.

As such, the bearing design must ensure high precision and address factors that limit high-speed capabilities. For instance, any loss in bearing dynamic stability can lead to vibrations, tool chatter, wear, and costly scrap. Higher speeds generate more heat because the lubricant shear rate increases. They also boost centrifugal force of the bearing rolling elements. Both factors can alter the bearing's design preload which, in turn, can generate even more friction and heat.

Optimizing the bearing system lets machine-tool builders raise speeds and achieve “first part correct” running accuracy on a consistent basis. The latest designs improve dynamic stability for chatter-free metal removal while maintaining lower operating temperatures. They also contribute to longer machine service life.
