What is Single & Double Side Fine Grinding?

Fine Grinding (flat parts – single or double-side) is the abrasive machining process for removing material using a bonded Superabrasive wheel at low speed with a liquid to keep the part cool. The fixed grain of a geometrically indefinable cutting shape acts like a plow (fig. 3) and material is removed by micro-grooving /-cutting (fig. 4).

Fine Grinding - an overview | ScienceDirect Topics

Abrasive flow machining (AFM) is a fine grinding process with rather low material removal rates. AFM is mainly used for polishing, deburring, and defined edge rounding and, due to the fact that a viscous carrier for the abrasive media is used, can be used to machine difficult-to-access cavities, inner contours, and undercuts in a reproducible ...
