Precision components play a crucial role in modern industry and technology. From aerospace to medical equipment, and then to electronic products, the high precision and reliability of these components provide guarantees for the performance and quality of products. So, how is the manufacturing process of precision components from design to production? Bigan Precision will delve deeper into this process, taking you to understand the key links and technical details involved.
1、 Design phase
The manufacturing process of precision components for preliminary design begins in the design phase. Engineers first need to conduct preliminary design based on product requirements, determining the functions, dimensions, tolerances, material selection, and manufacturing processes of components. This stage requires close communication with the client to ensure that the design meets the application requirements and performance standards of the product.
2. Computer aided design (CAD)
After the preliminary design is determined, engineers will use computer-aided design (CAD) software for detailed design and modeling. CAD software can draw three-dimensional models of components, display the shape, size, and connection relationships of each part, and conduct simulation analysis to evaluate the feasibility and potential issues of the design.
2、 Preparation stage for processing
After the design is completed, process planning is required to determine the manufacturing process flow of the components. This includes selecting appropriate processing methods, developing process routes, determining processing parameters, and establishing quality control standards. The purpose of process planning is to ensure the stability of the production process.
2. Material preparation: It is crucial to select suitable raw materials according to the requirements of design and process planning. The quality of raw materials directly affects the final performance of components. High strength, corrosion-resistant, and wear-resistant materials are usually used, such as stainless steel, titanium alloys, and high-temperature alloys. The selection of materials also needs to consider their processability and cost.
3、 Production stage
1. Numerical control machining: Numerical control machine tools (CNC) are the core equipment for manufacturing precision components. Numerical control machining controls the movement of machine tools through programming, achieving high-precision machining operations. Common CNC machining processes include turning, milling, drilling, and grinding. These processes can remove materials at the micrometer level to meet the tolerance requirements of precision components.
2. Electric discharge machining (EDM)
For some complex shapes or difficult to machine materials, electrical discharge machining (EDM) is an effective manufacturing method. EDM uses electric discharge pulses to perform small material removal on workpieces, thereby achieving precision machining. It is particularly suitable for manufacturing high hardness and high brittleness components, such as molds and cutting tools.
3. Able to quickly produce complex shaped components while reducing material waste. It is widely used in model making, prototype testing, and small-scale production.
4 Quality control is a key link in the manufacturing process to ensure that precision components meet design requirements. Common quality control methods include:
1 . Measurement and testing use high-precision measuring equipment such as coordinate measuring machines (CMM) and laser interferometers to detect dimensional and positional tolerances of components. Through these devices, measurement data can be obtained to determine whether the components meet the design tolerances.
2 . Non destructive testing techniques, such as ultrasonic testing, X-ray testing, and magnetic particle testing, can detect defects inside and on the surface of components, ensuring their structural integrity and reliability. These detection techniques can be carried out during the processing to avoid major quality issues.
5、 After assembly and testing manufacturing are completed, precision components need to be assembled and functionally tested. The assembly process requires high precision to ensure the correct fit between each component. Functional testing includes performance testing, fatigue testing, and environmental adaptability testing to verify the reliability and stability of components in actual use.
6、 Continuous improvement in the manufacturing of precision components is a continuous process of improvement. Through feedback and data analysis, continuously optimize design and process flow to improve product quality and production efficiency. Meanwhile, with the development of new materials, technologies, and equipment, the manufacturing process is constantly evolving, pursuing higher precision and performance.
