Is the standard value of ceramic parts bigger, its deviation bigger

Ceramic parts processing factories emphasize that machining should meet certain precision, which refers to the level that the main parameters of the actual geometry of the ceramics after machining are consistent with the idealized values required by the parts drawings.The discordant levels among them are called production bias.


The production and processing precision of ceramic parts processing factory includes three levels: on the one hand, specification precision, which limits the standard deviation between the surface of production and processing to within the necessary scope;On the other hand, the geometric shape precision limits the appearance deviation of the macroeconomic geometric shape of the surface layer, such as roundness, cylindricity, parallelism and straightness.
On the other hand, it is the precision of the mutual parts, which limits the deviation of the mutual parts between the standard of the surface of the ceramic parts processing, such as coaxiality, flatness and parallelism.The precision of production and processing is that the actual specifications, appearance and main parameters of several geometrical figures of the surface of ceramic parts after production and processing accord with the main parameters of idealized geometrical figures stipulated in engineering drawings.
The main parameters of the idealized geometrical figure, in terms of specifications, are the mean specifications;In terms of surface geometry, it refers to circles, cylinders, plane graphs, spheres and parallel lines.For the mutual parts in the middle of the surface, it refers to the parallel plane, vertical, coaxial output, symmetry, etc.
The deviation of the main parameters of the actual geometry of ceramic parts from the main parameters of the idealized geometry is called the production and processing deviation.The precision of production and processing and the deviation of production and processing are the technical terms to comment on the main parameters of surface geometry of production and processing.The precision of production and processing is considered by the tolerance grade. The smaller the grade value is, the higher the precision is.The deviation of production and processing is expressed by the scale value. The larger the scale value is, the greater the deviation is.
