Ways and methods of precision parts processing

For the machinery industry and the automotive industry, the substances they most often come into contact with are a series of parts and components. No matter which style or type, they will be more or less familiar with and know. Workers in related industries know which part is used in which structure or application position. However, no matter what kind of configuration, it needs to go through certain processing steps before it can be implemented in specific mechanical equipment. Therefore, professionals call this kind of step precision parts processing.

There are many ways to process precision parts, such as heat treatment. Parts refer to the single parts of machinery that cannot be separated. They are the basic components of the machine and the basic unit in the process of machine manufacturing. The manufacturing process generally does not require an assembly process. Such as sleeves, bushes, nuts, crankshafts, blades, gears, cams, connecting rod bodies, connecting rod heads, etc.

1. Cutting and processing of precision parts. Mainly include precision turning, mirror grinding and grinding. Micro-turning is performed on a precision lathe with a finely ground single crystal diamond turning tool. The cutting thickness is only about 1 micron. It is often used for processing non-ferrous metal materials such as spherical, aspherical and flat mirrors with high precision and smooth appearance. . 2. Precision parts processing. When the machining accuracy of precision parts is in nanometers, and even atomic units (atomic lattice distance is 0.1～0.2 nanometers) as the target, the cutting method of ultra-precision parts can no longer be adapted. It is necessary to rely on special precision parts processing methods, that is, the application of chemical energy. , Electrochemical energy, thermal energy, or electrical energy, etc., so that these energy surpass the joint energy between atoms, thereby removing the adhesion, union or lattice deformation of some atoms on the surface of the workpiece to achieve the purpose of ultra-precision machining. This type of processing includes mechanochemical polishing, ion sputtering and ion implantation, electron beam exposure, laser beam processing, metal evaporation, and molecular beam epitaxy.
