The way and way of precision parts processing

For the mechanical industry and automobile industry, the most frequently contacted materials are a series of parts and components. No matter which style or type, they will be familiar with and know more or less. The staff of relevant industries are knowledgeable about which structure or application location a part is used in. However, no matter which configuration, it needs to go through certain processing steps before it can be implemented in specific mechanical equipment. Therefore, professionals call this process precision parts processing.

There are many ways to process precision parts, such as heat treatment. Parts refer to the indivisible single parts in the machinery, which are the basic elements of the machine and the basic units in the mechanical manufacturing process. Its manufacturing process generally does not need assembly process. Such as bushing, bearing bush, nut, crankshaft, blade, gear, cam, connecting rod body, connecting rod head, etc.

Precision parts cutting. It mainly includes precision turning, mirror grinding and grinding. Micro turning is carried out on a precision lathe with a single crystal diamond turning tool which is finely ground. The cutting thickness is only about 1 μ m. It is commonly used to process high-precision and smooth parts such as spherical, aspheric and plane mirrors of non-ferrous materials.

Precision parts processing. When the machining precision of precision parts is in nanometer, or even in atomic unit (atomic lattice distance is 0.1-0.2nm), the machining method of ultra precision parts can’t be adapted. It is necessary to use the method of special precision parts machining, i.e. using chemical energy, electrochemical energy, thermal energy or electric energy, etc., to make these energy exceed the joint energy between atoms, so as to remove the part of the workpiece surface In order to achieve the purpose of ultra precision machining, atoms are attached, combined or lattice deformed. These processes include mechanical chemical polishing, ion sputtering and ion implantation, electron beam exposure, laser beam processing, metal evaporation and molecular beam epitaxy.
