Application:

Two inside diameters of a fuel injection valve body are to be bored while locating the workpiece OD.  The valve body is machined at 3.500 r.p.m., and it is crucial that the chuck provides sufficient clamping force to machine the part, while not distorting it during chucking. One ID diameter has a 7,5 micron roundness tolerance, and distortion during chucking will prevent this tolerance from being held consistently.

Required accuracy: 0,007 mm TIR
