"The appearance of products made by CNC machining and powder metallurgy is similar, but insiders know that CNC machining is more expensive than powder metallurgy, so why choose CNC machining to manufacture products?"? The following information is the difference between them:

Powder metallurgy is a process technology that prepares metal powders after forming and sintering or uses metal powders as raw materials to manufacture metal materials, composite materials, and various types of products.

CNC machining refers to the processing method of machining parts on CNC machine tools. Because digital information is used to control the displacement of parts and tools during the entire machining process, this method can solve the problems of a wide variety of parts, small batches, complex shapes, high accuracy, and efficient and automated processing,

Powder metallurgy has unique chemical composition, mechanical and physical properties that cannot be obtained by traditional melting and casting methods. Therefore, using powder metallurgy technology can directly produce porous, semi dense, or completely dense materials and products.

The object of CNC machining is a part with complex contours. It is characterized by the use of perforated tape or belt controlled machine tools for automatic processing to meet its high requirements for part size and accuracy.
