	Workholders - Hydra-Grip Arbors and Chucks

	MULTIPLE PART CHUCKING Considerable economy may be effected by machining several parts simultaneously using Davis hydraulic chucking devices.
Chucking diameters may vary within the established part print tolerances. All pieces will be positively gripped for whatever machining or inspection operation is required.

	INTERRUPTED-BORE CHUCKING Chucking parts with an interrupted bore having short bearing areas, can best be accomplished using A.G. Davis/AA Gage hydraulic arbors. The hydraulic system assures uniform concentric expansion under equalized pressure at both chucking surfaces.
Variation of bore diameters, within part tolerances, will not affect accurate positioning of the part on the true centerline of the interrupted bore.

TWO DIAMETER CHUCKING
Chucking parts locating in two different bore diameters is often necessary. Length of either bore may be too limited to locate the part accurately for machining from a single bore. Both chucking diameters are expanded concentrically to position the part on the common centerline of both bores.
