grinding machines limitations

Jan 26, 2021 · Precision CNC production grinding shines when parts require tight geometric tolerances and quality surface finishes. Typically, surface finishes in the range of 32 microinches Ra to as low as 4.0 microinches Ra and better are the numbers needed to be achieved. Comparatively, a traditional milling or turning operation might achieve a finish of about 125 microinches to 32 microinches Ra
