摘要： A chuck is provided employing a dish-shaped arbor with an elongated shoulder portion inclined rearwardly from a collar section to an outer periphery attached to an upstanding flange portion having a work-gripping face. Upon axial flexure of the arbor, the novel combination of the elongated shoulder and a tapered expander portion co-operate to impart parallel radial expansion of the work-gripping face to a workpiece bore thereby causing the bore to be gripped in substantially full-area abutment rather than in ''''line'''' contact as in prior art arbors. Also provided are air passages for supplying air under pressure to an annular groove in the surface of the work-gripping face to prevent possible entry of abrasive particles from entering between the work-gripping face and the workpiece bore.
