Device for testing the accuracy of measuring heads used in coordinate measuring machines and CNC machine tools

摘要

the apparatus is equipped with a measuring pin mounted in the measuring head (1), a pattern (3) with the reference, which meets the measuring mandrel, fixed to the movable part of the triaxial assembly (4) of the movement, and the control system and data processing (5), characterized by that,that pattern (3) has the shape of a cylinder with wgu0142u0119bieniem from the frontal surface of the reference, the reference area is shaped pu00f3u0142sfery concave focus diameter greater than diameter of the mandrel (2) measurement.
