OPTICAL-GRADE SURFACING TOOL

摘要

An optical-grade surfacing tool (101) is provided with a resilient return element (115) including a plurality of resiliently flexible strips (118) that transversely project from a rigid central mounting (104), each strip (118) having a distal portion (144) that engages by bearing directly upon a petal (134) of a flexible flange (131) that surrounds the rigid mounting (104). The distal portion is curved along a round loop such that the end (145) of each the strip (118) is rotated toward the rigid mounting (104).
