In mechanics, even small parts have many classifications and great functions. Although the parts are small, they play a great role. In modern society, the production of products cannot be separated from the application of mechanical equipment. There are many types of mechanical equipment. Generally, machines are composed of parts and components, while different types of equipment are composed of different parts. Pine Technology is positioned to provide customers with high-quality manufacturing services, focusing on the R&D and production of core parts of various equipment; To provide research, development and production services of non-standard mechanical parts for medical devices, engineering machinery and other fields. In order to improve the performance characteristics of parts in all aspects, high-precision machining is often involved, and there are many precautions in the process of precision parts processing. The staff shall operate strictly according to the requirements, so as to avoid failure during processing, which will affect the precision of precision parts.
