The performance of precision hardware parts processing

1. Casting performance
refers to whether the metal or alloy is suitable for some process properties of casting, mainly including flow performance and full casting ability; shrinkage, the ability of the casting to shrink volumetrically when solidifying; Segregation refers to the inhomogeneity of chemical composition.
2. Welding performance
refers to the characteristics of metal materials that weld two or more metal materials together through heating or heating and pressure welding methods, and the interface can meet the purpose of use.
3. Top gas section performance
refers to the performance of metal materials that can be forged without breaking.
4. Cold bending performance
refers to the metal material can withstand bending without cracking performance at room temperature, and the degree of bending is generally expressed by the ratio of bending angle or bending diameter d to material thickness a, the larger a or smaller d/a, the better the cold bending performance of the material.
5. Stamping performance The
ability of metal materials to withstand stamping deformation processing without breaking, stamping at room temperature is called cold stamping; The test method is tested by cupping test.
6. Forging performance
Metal materials can withstand plastic deformation without breaking ability in forging processing.

Precision machining

1. Processing mechanism
In addition to the precision of traditional processing methods, flying traditional processing has developed rapidly; At present, the traditional processing methods mainly include diamond tool precision hard hardening, disc diamond micronized grinding wheel precision grinding, precision high-speed cutting and precision grinding wheel grinding; Non-traditional processing methods mainly include electron beam, ion beam, laser beam and other high-energy beam processing, EDM, electrochemical processing, lithography, etc.; And there are composite processing methods such as spot grinding, electromagnetic grinding, magnetic fluid polishing, ultrasonic honing and so on with composite processing mechanism; The study of processing mechanism is the theoretical basis of precision and ultra-precision machining and the growth point of new technology.
2. Processed materials
The processed materials of precision machining have strict requirements in chemical composition, physical and mechanical properties, chemical properties and processing performance, and should have uniform texture, stable performance, and no macro and micro defects inside and outside; Only the processed material that meets the performance requirements can obtain the expected effect of precision machining.
3. Processing equipment and process equipment
Precision machining should have high-precision, high-rigidity, high-stability and automated machine tools, corresponding diamond tools, cubic boron nitride tools, diamond grinding wheels, cubic boron nitride grinding wheels; And the corresponding high-precision, high-rigidity fixture and other process assembly to ensure the processing quality.
4. Testing
Precision machining must have corresponding detection technology to form an integration of processing and testing; Offline inspection refers to sending the workpiece to the inspection room for inspection after the processing is completed; In-place detection means that the workpiece is not unloaded after the processing is completed on the machine tool, and it is detected on the spot, and if any problems are found, it is convenient to re-process; Inline inspection is carried out during processing so that dynamic error compensation can be actively controlled and implemented.
5. Working environment
Precision machining requires working in a certain environment to achieve technical parameters in precision and surface quality; The conditions of the working environment mainly have convenient requirements such as temperature, humidity, purification, and vibration prevention, and special requirements for fashion and noise, light, static electricity, electromagnetism, radiation, etc.
