High precision machining of mechanical components: is technology or process more critical
In the field of high-precision mechanical component processing, technology and craftsmanship are like the wings of a bird and the wheels of a car, jointly promoting the improvement of processing quality and efficiency. It is difficult to simply judge which one is more critical.
Advanced technology is the cornerstone for achieving high-precision machining. Taking ultra precision machining technology as an example, using machine tools with nanometer level precision, it is possible to accurately control the relative motion between the cutting tool and the workpiece, achieving sub micron or even nanometer level machining accuracy. In the aerospace field, high-precision blade manufacturing for engines requires the use of five axis linkage machining technology, which enables cutting tools to machine complex blade surfaces from multiple angles, ensuring the aerodynamic performance of the blades. This advanced technology endows processing equipment with powerful capabilities, breaking through the precision limitations of traditional processing and providing hardware support for manufacturing high-precision components.
However, exquisite craftsmanship is equally indispensable. Craftsmanship is the scientific planning and precise execution of the machining process. From blank selection and determination of machining allowance, to optimization of cutting parameters and arrangement of machining sequence, every step contains the wisdom of technology. In electronic chip manufacturing, photolithography process is the key to determining chip performance. By carefully designing the photolithography process and precisely controlling parameters such as exposure time and development conditions, complex and precise circuit patterns can be etched on the surface of tiny chips. Reasonable processes can fully utilize the performance of equipment, make up for some technical deficiencies, optimize component processing, and ensure the stability of product quality.
In the processing of complex components, technology and process work closely together. For example, the precision machining of automobile engine cylinder bodies requires high-precision CNC machine technology to ensure the dimensional accuracy of cylinder roundness, cylindricity, and other dimensions, as well as advanced boring and honing processes to ensure the roughness and sealing of the inner surface of the cylinder. Technology provides the means of implementation for processing, while craftsmanship combines these means in a reasonable manner and transforms them into actual high-quality products. Moreover, with the increasing demand for component processing efficiency in the market, advanced technology combined with optimized processes can significantly shorten the processing cycle. If high-speed cutting technology is used in conjunction with a reasonable tool path planning process, it can significantly improve cutting speed and reduce processing time while ensuring machining accuracy.
In the processing of high-precision mechanical components, technology and process are interdependent and mutually reinforcing. Only by continuously introducing advanced technology and focusing on process research and optimization can enterprises manufacture high-precision and high-quality mechanical components in the fiercely competitive market, meeting the growing demands of various industries .
