What are two types of precision machining and manufacturing processes for parts?

Precision machining is a type of mechanical processing that involves the processing of workpieces that meet the line tolerances required by the drawing. When the workpiece is in this process, its performance characteristics and shape structure will undergo a certain degree of change.

With mechanical processing, there will naturally be corresponding parts. Mechanical component design, as a discipline in the mechanical field, is one of the popular majors chosen by science students and one of the strongest courses in engineering. At present, this major requires not only good knowledge in science and engineering, but also good drawing skills and spatial imagination. Due to the development of domestic industry and changes in demand, the demand for personnel in the mechanical processing industry is also increasing, and the employment rate of the mechanical profession can reach 95%.

With the development and progress of domestic industry, mechanical processing has undergone significant changes, with the emergence of precision machining technology. Many industries, such as home appliances, automobiles, hardware, and medical manufacturing products, use precision components to a greater or lesser extent. It may only be a component of a mechanical device, or it may be a core component. In summary, it is important and plays an irreplaceable role.

There are two processes for precision machining and manufacturing of parts, one is hot working, and the other is cold processing. hot working is to make parts change chemically or physically at very high temperature to meet the requirements of appearance change. Cold working, on the other hand, requires no chemical or physical changes at room temperature to meet the requirements of shape changes, and generally adopts cutting technology. In the future, while meeting the requirements of processing and environmental protection, precision mechanical processing will be combined with science and technology to become an important and sustainable science.

Hardware mechanical parts processing is a processing method with a processing accuracy of 1 micrometer. Precision mechanical processing is achieved using precision machine tools, precision measuring tools, and instruments under strictly controlled environmental conditions. Ultra precision machining is a machining method that achieves or exceeds a machining accuracy of 0.1 micrometers.

In the aviation and space industry, hardware mechanical parts processing is mainly used to process precision mechanical parts in aircraft control equipment, such as precision parts in hydraulic and pneumatic servo mechanisms, gyroscope frames and shells, air and liquid floating bearing components and floats. Precision aircraft parts have complex structures, low stiffness, high accuracy, and a large proportion of difficult to machine materials.
