Machined parts are parts manufactured from raw materials by machining methods (such as turning, milling, grinding, drilling, etc.), which have the following characteristics:
1. high accuracy: machining can achieve high dimensional accuracy and shape accuracy. Modern excellent processing equipment and technology, such as CNC machining center, can control the dimensional error at the micron level, and can meet the requirements of various high-precision equipment and products, such as aircraft engines, precision instruments and other fields with high requirements for the accuracy of parts.
2. good surface quality: through different processing technologies and surface treatment methods, machined parts can obtain different degrees of surface finish, from ordinary processing surface to mirror like smooth surface, to meet different use requirements. For example, some moving parts that need to reduce friction, such as the inner wall of the hydraulic cylinder, will be processed to obtain a low roughness surface to reduce the friction coefficient and improve the sealing performance.
3. machining complex shapes: with the help of various machining methods and multi axis linkage processing technology, parts with complex shapes can be manufactured. Whether it is the impeller and mold with complex surface, or the box with various cavities and channels inside, the machining can achieve the correct processing and meet the design requirements.
4. strong adaptability of materials: machining can process various metal materials (such as steel, iron, aluminum, copper, etc.) and some non-metallic materials (such as plastics, ceramics, etc.). Different materials have different physical and chemical properties. By selecting appropriate processing technology and cutting tools, various materials can be processed into parts that meet specific performance requirements.
5. batch production capacity: machining is suitable for batch production. Through the use of automated production lines, special fixtures and tools, efficient and stable batch processing can be achieved to ensure the consistency of product quality. For example, the cylinder block, transmission housing and other parts of the automobiles engine are mass produced through large-scale machining production lines.
6. high strength and reliability: in the machining process, the material is cut, shaped and deformed, and the internal structure is optimized, which improves the strength and toughness of the parts. At the same time, high-precision processing ensures the fitting accuracy and assembly quality of components, so that the reliability of the whole mechanical system is improved.
7. good repairability and refitability: some worn or damaged machined parts can be repaired by reprocessing and repairing the worn parts to extend their service life. In addition, the machined parts are also convenient for refitting and upgrading to adapt to different working conditions and technical requirements.
