Abstract
The application relates to a process for working a workpiece, in which process an abrasive liquid is sprayed onto the workpiece, via a nozzle, at relatively low pressures which are sufficient to shape and/or polish the surface of the workpiece. The workpiece can be both shaped and polished in a single working step. Abrasive particles or polishing particles may be contained in the abrasive liquid. The pressure of the abrasive liquid lies below 50 bar, preferably below 20 bar. By arranging two nozzles in such a manner that the liquid jets intersect one another at a point, it is possible to set an accurate working depth.
Claims17
Process for working a workpiece, wherein an abrasive liquid is sprayed onto a workpiece, via at least two nozzles, each of which is disposed at an angle with respect to the workpiece and liquid jets from which intersect one another on or below the workpiece surface, wherein the abrasive liquid is sprayed onto the workpiece at a pressure of less than 50 bar.
Device for working materials, comprising at least two nozzles which are positioned in such a manner with respect to one another that the liquid jets from the nozzles intersect one another at a point, a feed line which is connected to the nozzle and contains a pump for feeding an abrasive liquid to the nozzle, wherein the pressure of the feed pump is less than 100 bar.
