Abstract (en)

[origin: WO02074489A1] The invention relates to a device for the abrasive machining of surfaces of elements. Said device comprises a tool (1) with an inlet (11) and an outlet (12), a supply unit that supplies a liquid to the inlet (11), said liquid containing dissolved abrasive agents and emerging from the outlet (12) and a positioning device, which guides the tool over the surface to be machined, positioning said tool in such a way that the outlet lies opposite the surface to be machined. According to the invention, the surface area of the annular gap (3) that is formed by the limiting walls (13) of the outlet (12) and the surface (2) to be machined is smaller than the cross-sectional surface of the inlet (11).
