Abstract (en)
[origin: WO2011070267A1] The invention relates to an optical-grade surfacing tool (101) provided with a resilient return means (115) comprising 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). Said distal portion is curved along a round loop such that the end (145) of each said strip (118) is rotated toward the rigid mounting (104).
