Optical lens surface smoothing device - includes abrasive elements in form of diamond pellets integral with supple metal netting support applied by pressure against driving tool

摘要

The device includes abrasive elements (3) integral with one face of a supple support structure (1) presenting a honeycombed or porous texture are applied by pressure against a driving tool (2). The supple support is formed from a metal netting with a fine mesh. The abrasive elements (3) are in the form of diamond powder pellets on one face of and inside the support structure (1) in a disposition such that, during tool rotation, their fields of action overlap. The pellets are located in two perpendicular directions, with the distance from the support centre different for each pellet. The abrasive elements can be located in a spiral on the support. USE - Eliminates the need for diamond powder pads.
