Why is there no flaw in precision machining?

Precision machining refers to a variety of machining processes whose machining accuracy and surface finish are higher than those of other machining methods. Precision machining includes: precision cutting, high-brightness and high-precision grinding. The precision of precision machining is usually controlled within 10μm-0.1μm, the tolerance level is above IT5, and the surface roughness Ra is within the range of 0.1μm.
Take the submarine as an example. When we dive for a period of time, a verification location will appear, but if the gyroscope support is extremely accurate, the submarine does not need to come out. Such a high-precision support can only be processed by an ultra-precision machine tool. This can be seen , How important is precision machining?
Today we are going to discuss the high-tech slow-moving wire processing technology. Precision processing represents the high level of current machine tools. The parts processed by it have high precision, which can be guaranteed to be within the range of ±0.22mm.
Similar to precision machining, the machining accuracy can be guaranteed within the range of ±0.22mm, the extremely high machining efficiency can be as high as 400mm²/min to 500mm²/min, and the surface roughness of the parts can reach Ra0.05μm, so the object can have Perfect processing surface quality, there is basically no deterioration layer on the surface, and the electrode wire with a diameter of 0.02mm can be used for micro-finishing. For the main machine of the precision machining machine tool, most of them have a heat balance system, and some of the machine tools are used for cutting in oil. This machine tool has a very complete function and a high degree of automation. It can directly complete the precision machining of the mold. The mold life has reached the level of mechanical grinding.
For entry-level precision machining, most of the manufacturing methods of cutting one trimming and cutting one trimming can be used to stably achieve the surface finish in the range of Ra0.8μm, and the processing accuracy is ±0.00mm, but in many cases, only 0.15mm can be used. In the cutting process of wire electrode or above, the surface microstructure and corners of precision machining have a certain gap with advanced machine tools.
