The lubrication of spindle bearings Machine tool main spindles running at higher speeds enable ever greater machining rates and shorter machining times per workpiece. These high speeds result in demanding operating conditions for rolling bearings. Spindle bearings are required to operate at high speed factors (n × dm) and run with reduced friction to keep bearing temperature low. The bearings have to carry both radial and axial loads. Naturally, premature bearing failure must be prevented. How to select the right lubricating grease If you wish to determine the free bearing space with full accuracy,...

The lubrication of work holding systems It is important to make sure that the correct lubricant is chosen for lubrication of the work holding chuck. After all, the principal task is to generate a constant defined clamping force for a high number of clamping cycles. If the clamping force decreases, tools or workpieces may come loose. This applies to all types of chuck designs – scroll, cam or spiral chucks. Lubricating pastes have proven very useful in these applications as they adhere well to the friction points and provide sufficient lubricity even when applied as a very thin film. Most pastes...

The lubrication of drive and guide systems Speed-viscosity ratio In most modern machine tools, workpieces and tools are positioned by means of antifriction guideways or slideways. They are normally moved by ball screws. 15 m/min to 60 m/min vibration < 1 m/s2 The correct advanced speciality lubricants support your components in meeting these requirements. Speciality lubricants made by Klüber Lubrication protect against wear also when subject to micro-movements, and due to reduced friction they facilitate machine start-up. They provide high-performance corrosion protection, a good demulsifying...
