Process for precision grinding two cooperating truncated-cone surfaces, apparatus for carrying out this process, use of this apparatus and precision ground article resulting upon the application of this process

摘要

in order to obtain a highly precise surface grinding of a tronconiques, internal and external, the other (11, 20).and in order to obtain a precise value of the particular diameter (da) of an edge (19), formed by the junction of two surfaces tronconiques.the device and the method include the installation of two grinding wheels and grinding spindle is (5.17) on a table.with an angular displacement of the table to correct the one hand and, on the other hand, said surfaces to provide adequately for the two wheels to the dressing tool (13, 13a) 21.21 (a).the position of training tools is the active surfaces of grinding wheels so that the correction is then automatically with the desired precision in the diameter of the edgejunction of the conical surfaces.;this method and this device are positioned on the front surface of a correction fuel injection nozzle for an engine.
