Northfield Precision Instrument Corp. introduces its Model 870 sliding-jaw air chuck (.0001 TIR). This air-actuated chuck has two moving jaws for gripping square or rectangular parts.
In this custom application, the company's customer requested Vee-block type jaws to accommodate a range of drill sizes with each set of Insert Pads. The drill tip (not shown) stops on the axial locator (mounted to the face of the chuck), and the Insert Pads (mounted in their subjaws) clamp down on the OD of each drill while they grind its shank.
The insert pad and subjaw arrangement allow for quick changeover from size to size.
