Precision CNC Machining is a type of CNC machining, which is used in industrial production to classify machining levels based on precision. In mechanical manufacturing, the specification of tolerance levels is based on the principle of ensuring both the accuracy of the machine and the interchangeability of components, as well as the economy of manufacturing the machine. That is to say, as long as low precision can ensure the functionality and accuracy of the machine, non-standard mechanical parts should not be required to have high precision, as it will increase manufacturing costs.

Therefore, in the processing of precision CNC parts, the higher the precision required, the higher the quotation for the parts. This is the basic requirement for reducing the errors generated during the processing of precision CNC parts. However, to some extent, the reduction of errors will become more difficult in the later stages.

In some high-tech products or medical equipment, the precision requirements for these components will be higher, so the fees will also be more expensive. The CNC machining industry is constantly deepening technological reforms in production and manufacturing, so there are now many new technologies, materials, and processes added. On the one hand, it improves the manufacturing level of non-standard precision CNC machining parts, and on the other hand, it greatly improves production efficiency. In the process of non-standard precision CNC parts processing, some fixtures and jigs are used at night to assist, which improves production efficiency and the accuracy of processed workpieces, while also reducing the scrap rate of operators and so on.

The production equipment required in the precision CNC component processing and production process includes lathes, milling machines, grinders, internal/external cylindrical grinders, fast/slow wire feeding, spark machines, fine hole discharge motors, CNC machining centers, and other precision machines. These production equipment require some wear and tear fees, and the higher the precision of the equipment, the higher the product quality and price it can bring. The personnel allocation, processing materials, special auxiliary tools and cutting tools, and reasonable profits required by the enterprise are all included in the quotation.
