MMP Technology maps a surface as a collection of different frequencies of roughness. It then removes only the targeted frequency ranges, moving from the highest frequencies to lower ones. As a result of this extremely precise approach, MMP Technology achieves mirror-like surfaces with far less material removal than traditional cutting action polishing processes
However, since MMP Technology is an isotropic (homogeneous) treatment, if obtaining a mirror-like surface requires removal of form errors (i.e. low frequency), MMP Technology may not be a good solution. Defects in the form of the part will require localized removal of material, and probably a lot of material relative to the amounts MMP Technology typically removes. In general, if a part requires non-homogeneous removal of material (i.e. changes to the actual shape of the part), MMP Technology is not likely to be the best choice.
In conclusion, depending on the applications and markets, the mirror-like surface produced by MMP Technology is often the best choice due to low material removal, the ability to preserve the initial shapes and designs, an improvement of technical properties of the surface, reproducibility and homogeneity, accessibility to complex shapes, and superior lead times and overall cost.
