cnc machining service - Runsom Precision

CNC turning is a process of machining parts with cylindrical features from metal or plastic rod stock. Compared with CNC milling, the turning process allows us to make any circular parts effectively such as shafts, worms and spheres, and it can apply to creation of the parts with complex external and internal geometries and various threads.

A Study of Surface Roughness in the Micro-End-Milling …

of parts created by a micro-end-milling process as compared to parts created by a traditional end-milling process (Lee, et al 2001). It appears that run-out also has a more significant effect on the surface quality of micro-end milled parts. The surface roughness traces reveal large peak to valley variations with a period of twice the chip load.
