CNC machining technology has the characteristics of high automation in application. Compared with traditional machining technology, it has better accuracy and precision in product processing and manufacturing. The technology uses a digital information system, which can precisely cut and manufacture products and avoid human errors. In the application of CNC machining technology, the quality and production efficiency of processed products are greatly improved, the time for processing products is shortened, and the production cycle of products is accelerated. High-speed CNC machines allow us to manufacture high-precision copper molds, mold cavities, mold bases, lifters and other mold components in a very short time. Additionally, using a 5-axis mill, we can mill deep pocket features in hours, whereas EDM used to take days.
