Abstract
A chuck grips the housing of a hub assembly to hold it fast and further engages a hub spindle that is within the housing and rotates the spindle on a bearing that is between it and the housing so that a flange on the hub may be machined with precision. The chuck includes a fixed base that carries jaws which clamp down on the housing to firmly hold the housing. It also includes a rotatable base and an arbor carried by the rotatable base and engaged with the spindle of the hub to impart the rotation of the hub. The arbor can shift radially with respect to the rotating base to accommodate misalignment between the axes of rotation for the hub and the rotating base. A bearing lies between the arbor and rotating base to resist an axially directed force applied to the arbor to expand it in the hub spindle.
