ABSTRACT:
A workholding apparatus includes a body, and a workholding sleeve composed of metal and carried by the body. A fluid chamber receives a fluid between the body and the workholding sleeve. Under fluid pressure, the sleeve is radially displaceable and recoverable to a high degree. For example, the sleeve is radially displaceable to at least one percent in diameter with runout within about 0.03% of its diameter, and after release of fluid pressure repeatably recovers to within about 0.01% of its original relaxed diameter. In another example, when displaced under fluid pressure, the sleeve experiences substantially complete and repeatable strain recovery of at least about 2% of its overall cross-sectional area. Preferably, the sleeve is composed of Nitinol.
