Abstract
In a self-centering steady rest (1) with three holding members (12,13,14) acting upon a workpiece (2) to be chucked, an adjusting member (15) interacting with the two outer holding members (13,14) is adjustable in the longitudinal direction (A) of the central holding member (12) by an adjustable distance corresponding to the sum of respective deformations of the outer holding members. This makes it possible to compensate not only the elastic deformations of the two outer holding members (13,14), but all back rest components involved in the transmission of forces. Consequently, reproducible centered chucking of the workpiece (2) can be accomplished at all times with great chucking accuracy.
