Better materials and sealing technologies meet the challenges of modern machine tools and coolants. Bigger, faster machine tools obviously put greater demands on spindle bearings. Most spindles use a ...

Bearinx-online is a detailed spindle design calculation tool from Schaeffler that helps optimise bearings for main spindles early in the design process. This provides design engineers with a virtual ...

Modern CNC machine tools work under increasingly diverse cutting conditions. They must handle workpieces of various sizes and materials, and produce good surface finishes while operating at ever ...

Bearings define speed, load-carrying capacity, precision, and stiffness, and they contribute to the spindle operating temperature, vibration, and noise during operation. It wasn’t so long ago that a ...

The challenge that machine tool builders face when designing spindles for milling machines and lathes is selecting bearings with the optimal balance of speed, load-carrying capacity, stiffness, and ...

At EMO 2017, Schaeffler presented a revolutionary system for maximising the OEE (overall equipment efficiency) of machine tools – a newly developed range of sensors for main spindle monitoring that ...

For the benefit of our readers, what is the principle of Aerostatic bearings, and how do they compare to roller-element or oil hydrostatic bearings? There are two types of aerostatic bearings, inlet ...
