Abstract

A one-part tool consisting of an effective tool range with a spindle and mounted hydrostatically in a plain bearing, by virtue of the regions, namely effective tool range/spindle bearing points, obtainable in chucking fixture, without the use of ball bearings, possesses an extremely high degree of true running and thereby guarantees the highest possible cutting performances and lifetimes, whilst ensuring the best surface qualities. <IMAGE>
