Traditional CNC machining, recently, automation and numerical control have been used to improve the processing ability, and great progress has been made in efficiency and accuracy. 

However, the basic steps are still inseparable from the gradual processing of parts such as turning, planer, milling, grinding, drilling and throwing. 

The accuracy and complexity of the machining method are far superior to those of other methods. 

However, due to low effective utilization of material and the limitation of equipment and tools, some parts cannot be machined. 

On the contrary, MIM can effectively utilize materials, and the product shape is not limited. For the manufacture of small, complex and difficult shape precision parts, MIM process has lower cost, higher efficiency and competitiveness than CNC machining.
