use of a device for the abrasive machining of surfaces of elements and, in particular, of optical elements. workpieces

摘要

A device for abrasive machining of surfaces of components, comprising a tool ( 1 ) having an inlet ( 11 ) and an outlet ( 12 ); a supply unit for conveying to the inlet ( 11 ) a liquid in which abrasive agents are dissolved and which emerges from the outlet ( 12 ); and a positioning means which guides the tool across a surface to be machined and simultaneously positions the tool in such manner that the outlet faces the surface to be machined, an area of an annular gap ( 3 ) defined by boundary walls ( 13 ) of the outlet ( 12 ) and the surface ( 2 ) to be machined being smaller than a cross-sectional area of the inlet ( 11 ).
