CNC Machining of Non-Ferrous and Ferrous Metals

CNC machining refers to the machining process proceed by Computerized Numberical Control (CNC for short). It is aided by the CNC to reach a high and steady accuracy with less labor cost. Machining is any of various processes in which a piece of raw material is cut into a desired final shape and size by a controlled material-removal process.

The processes that have this common theme, controlled material removal, are today collectively known as subtractive manufacturing, in distinction from processes of controlled material addition, which are known as additive manufacturing. For some of the applications, just castings or forgings without machining could reach the desired tolerances and surface requirements. However, for most situation, the CNC machining are needed to match the customer's unique specifications and to make sure that the finished metal parts could work properly with other parts. Even for the investment casting parts, which have much better surface and tolerance grade than other metal forming process, still need additional processing.

Ferrous Metalss for CNC Machining

Cast Iron including gray iron, ductile iron and malleable cast iron

Carbon Steel from low carbon steel, medium carbon steel and high carbon steel.

Stainless Steel, Duplex Stainless Steel, Precipitation Hardening (PH) Stainless Steel
