Abstract
A cross-blade flexure block is prepared by machining a first cross-blade flexure element and a second cross-blade flexure element. Machining is accomplished by a technique such as electrical discharge machining or water jet machining. Each cross-blade flexure element is a single integral piece, with no braze joints therein. The first cross-blade flexure element and the second cross-blade flexure element are assembled together to form a flexure block.
