What are the tools for measuring numerical parts?
The cutting precision of the machine tool, also called dynamic accuracy, is a comprehensive precision, it not only reflects the geometric precision and the orientation precision of the machine tool, but also includes the error caused by the specimen material, environment temperature, CNC machine tool performance and cutting conditions and other factors and measurement error. Cutting accuracy testing can be divided into single machining accuracy test and processing, a standard comprehensive test piece, accuracy test of two kinds. In addition to the special requirements, all the materials used in the cutting process are made of first grade cast iron, and carbide cutting tools are cut according to the standard cutting amount.
CNC machine tool positioning accuracy, CNC machine tools refers to the coordinates of machine tools under the control of numerical control device movement can achieve position accuracy.Measurement of linear motion detection tools are: standard gauge, micrometer and group scale, optical reading microscope and dual frequency laser interferometer. Rotary motion detection tool: table 360 courses of accuracy or indexing of the standard angle polyhedron high-precision circular grating and parallel light tube etc..
The geometric accuracy test of CNC machine tools is also called static accuracy test. The radial drilling machine is a comprehensive reflection of the geometric error of the key components of the machine tool after assembly.At present, the commonly used detection tools to detect the geometric precision of machine tool with precision level precision, square box, square, flat foot, light pipe, dial gauge, micrometer, high precision and good rigidity test rod rod gauge. The accuracy of the inspection tool must be higher than the measured geometric accuracy, otherwise the measurement result will not be credible.
