DMG MORI COMPONENTS Kenji Oishi Executive Managing Director, DMG MORI Co. Ltd. Alfred Geißler Managing Director of DECKEL MAHO Pfronten GmbH this innovative steel exhibits extremely high load carrying capacity, resistance to wear and thermal stability. New benchmarks in damage statistics That is why Alfred Geißler is convinced that the current failure rate of 1 % can be even further reduced with the new generation “MASTER” spindles. “Currently there are very few spindle failures and these are caused by wear, insufficient lubrication and contami- nation of the bearing. We will achieve new benchmarks with the Vacrodur bearings by improving all these issues.” « New material for spindle bearings The combination of a generously dimensioned bearing design with the high-performance roller bearing material Vacrodur is what makes these so special. Vacrodur has sig- nificant benefits compared to the traditional material 100Cr6, Alfred Geißler tells us. Its high hardness values of up to and even more than 65 HRC are especially outstanding.
