ABSTRACT:
A center clamp used with a machining tool having an annular edge has a C-shaped body having an inner end inside the edge and an outer end outside the edge and spaced from it along a clamp axis. A push rod extends along the axis through the outer body end. A rotary joint centered on the axis has an inner part on the inner body end and an outer part rotatable on the inner part about the axis. An axial actuator relatively axially shifts the body and the push rod and thereby clamps a workpiece between an end face of the rod and the outer part of the joint. An angular actuator pivots the push rod about the axis and thereby, when the workpiece is clamped between the rod and the joint, pivots the workpiece about the axis.
