Abstract (en)
[origin: EP0816018A1] A polishing disc support, designed to receive a layer of a fine abrasive paper or cloth used e.g. for finishing electronic components used in printed circuits, comprises a disc-shaped body (1) e.g. of aluminium with a centering hole (4) and an eccentric drive hole (5) in one face. The opposite face of the disc is coated with a layer (6) of material which is softer than that of the disc, to which the abrasive layer is applied. The softer layer (6) has a thickness of 5 mcm to 4 mm, a Shore D hardness of more than 12 and is made from PTFE, which can be applied by spraying or in the form of a layer attached by adhesive.
