What is CNC machining?
CNC machining refers to a machining method of controlling the displacement of parts and tools with digital information on a numerically controlled machine.
It is an effective way to solve the problems of various types of parts, small batch size, complex shape and high precision requirement, also helps to achieve high efficient and automated processing. We use CNC machining to not only manufacture parts and prototypes, but also to make mold tools that can be used in our forging and stamping services.
