Abstract
A machining device has a stationary member and a rotating member. A plurality of bearings on one of the members engages a surface of the other. At least one of the bearings is radially fixed, while the remainder of the bearings are radially adjustable. In another aspect of the invention, the bearings are rotatable on a first cylindrical portion of a mounting shaft that has a second cylindrical portion attachable to the machine. A radial undercut is provided around a flange between the first cylindrical portion and the second cylindrical portion.
