The start-up costs are lower compared to other manufacturing processes (e.g., die casting, MIM), so that smaller series and prototypes with tight tolerances can also be manufactured, but often with high economic costs.
Depending on the material and the component geometry, CNC machining can be economical even for high volumes. A high surface finish is achievable. Center-line roughness values in the range of Ra 0.8-3.2 are typical. Values lower than Ra 0.8 can also be achieved.
There are almost no limits to the choice of materials here. As a rule, CNC production has no negative influence on the mechanical properties of the processed materials. Furthermore, the machining of high-strength and hard (even hardened) materials is also possible Due to a high degree of automation and the fact that no tools have to be created, short delivery times are possible.
