1. Differences in machining principles
The machining principles of precision machining and ultra-precision machining are roughly the same. They are both processed using advanced equipment and processed on parts by rotation, cutting, stretching, etc. The main method of precision machining is CNC machine tool machining, which uses grinding and cutting tools to process workpieces; ultra-precision machining mainly uses non-traditional precision machining methods such as laser machining, electrolytic machining, and EDM machining.
2. Differences in process technology
There are also differences in process technology between precision machining and ultra-precision machining. In precision machining, CNC machining technology is mainly used, which is a machine tool technology that can perform rough machining and finishing machining efficiently and accurately. Ultra-precision machining uses more advanced process technologies, such as laser machining, EDM machining, etc., which can better ensure the accuracy and surface quality of the workpiece after machining.
3. Differences in machining accuracy
The main difference between precision machining and ultra-precision machining lies in the difference in required machining accuracy. The machining accuracy of precision machining is required to be within 0.1mm, while the machining accuracy of ultra-precision machining is required to be 0.01mm or even smaller. Therefore, ultra-precision machining pays more attention to the surface finish and dimensional accuracy of the workpiece after machining, and can meet the needs of higher precision machining.
4. Differences in application fields
The application fields of precision machining and ultra-precision machining are also different. Precision machining is widely used in the fields of mechanical manufacturing, automotive parts processing, etc., while ultra-precision machining is widely used in high-end fields such as microelectronics, optical instruments, and aviation manufacturing.
