The machinery required for machining consists of digital display milling machine, digital display forming grinder, digital display CNC lathe, EDM machine, all-round grinder, CNC machining center, laser welding, middle wire, fast wire, slow wire, grinding machine, internal and external grinding machine, high Precision CNC lathes, etc., can realize the production and processing of high-precision parts such as turning, milling, planing, grinding, etc. This type of machinery is good at turning, milling, planing, grinding and other production and processing of high-precision parts, and can produce various irregular parts. , the machining accuracy can reach 2μm.
The production and processing precision of a machining plant includes three levels: on the one hand, the specification precision, which limits the specification error between the production and processing surfaces to each other within a certain range; on the other hand, the geometric pattern precision limits the production and processing surface The macroeconomic policy geometry shape error, such as concentricity, coaxiality, flatness and parallelism. On the other hand, it is the mutual positional precision, which limits the mutual positional error between the production and processing surfaces of the machining plant, such as parallelism, flatness and flatness. The production and processing precision is the level of conformity between the main parameters of the actual specifications, appearance and position of the surface of the parts and components after production and processing and the main parameters of the ideal geometric figures required by the construction drawings.
The offset value of the main parameters of the actual geometric figure and the main parameters of the ideal geometric figure is called the production and processing error. Production and machining precision and production and machining error are both professional terms for evaluating the main parameters of the production and machining surface geometry. The production and processing precision is considered by the tolerance level. The smaller the level value, the higher the precision; the production and processing error is expressed by the standard value, and the larger the standard value is.
