Do you know what precision machining is?

Latest company news about Do you know what precision machining is?

What is fine machining? What kind of processing is fine machinery mainly used for? What are the requirements for information? The machining accuracy is more accurate than that of ordinary machines. Machines that reach or exceed 0.1 μ m are fine machines. Generally, fine machining is completed under strictly controlled environmental conditions by using fine machine tools, fine measuring tools and meters. It can be used for fine fittings in hydraulic and pneumatic servo mechanisms of aerospace industry, frames and shells of gyroscopes, air and liquid floating bearing components and floats. The data on fine machining can be divided into two categories: metal data and nonmetal data.

Do you have any request for information on fine machining? Not all materials are suitable for processing with fine parts. As for metal materials, the hardness is in the order of stainless steel, cast iron, copper and aluminum. The processing of ceramics and plastics belongs to the processing of non-metallic materials. It is limited to the hardness request of processing parts. In some places, the higher the hardness value, the better. However, the processing data cannot be too hard, or the processing cannot be stopped. Therefore, it is necessary to select reasonable materials for the parts according to the role of the processed devices. In ordinary places, it is better to compare the soft and hard materials.

Before stopping fine machining, you must pay attention to the density (hardness) of the selected materials. If the hardness has exceeded the hardness of the machine parts (lathe tools), not only the parts cannot be machined, but also the parts may be damaged or risk may be formed. For example, in the past, there have been incidents of turning tools flying in and injuring people. Therefore, for mechanical processing, the material must be lower than the hardness of the machine tool, so that it can be processed.

Fine machining mainly includes fine turning, fine boring, fine milling, fine grinding and grinding. Effect: the boundary line or feature dimension tolerance of the part is below micrometer; Geometric shape and mutual position accuracy reach micron or angular second level; The surface micro unevenness is less than 0.1 μ m; Mutual fittings can meet the requirements of combination force and accurate mechanical or other physical characteristics.
