Optical quality surfacing tool

An optical quality surfacing tool comprising:

• a base including a flexible collar subdivided into petals, and a rigid support surrounded by the collar, the rigid support having a transverse end surface;
• an elastically compressible interface connected to the base, the interface including a central part located in line with the end surface of the rigid support and a peripheral part located transversely beyond the end surface of the rigid support, the elastically compressible interface being applied against and covering an end surface of the collar situated on the same side as the end surface of the rigid support;
• a flexible buffer configured to be applied against a surface to work, the flexible buffer being connected to the interface on the opposite side to the rigid support, the flexible buffer including a central part located in line with the end surface of the rigid support, and a peripheral part located transversely beyond the end surface of the rigid support;
• and
• elastic return means disposed between the rigid support and the peripheral part of the interface, the combination of the peripheral part of the buffer, the peripheral part of the interface and the elastic return means forming a means for stabilizing the tool during the surfacing, the tool being configured to perform surfacing substantially at the central part of the buffer, the elastic return means including a plurality of elastically flexible strips which project transversely from the rigid support, each strip having a distal portion in direct bearing cooperation with one of the petals, the distal portion being curved in a rounded curl such that an end of each strip is turned towards the rigid support.
