Ukugqitywa komatshini ogudileyo kuvelisa umphezulu one-arithmetic mean roughness, eyaziwa ngokuba yi-Ra, ye-1.6 μm (63 μin).Njengokugqitywa komatshini, ukugqiba komatshini okugudileyo kukwabonelela ngokususwa komphetho obukhali kunye nokuchithwa kwenxalenye.Ekubeni umphezulu ugudileyo kunomgangatho wokugqiba umgangatho, amanqaku kunye nokungafezeki akubonakali kangako.Ukugqitywa okugudileyo okwenziwe ngomatshini akufumaneki ngokugqitywa kwe-cosmetic.

Ezinye iindawo zifuna ukugqitywa komphezulu ogudileyo kunalowo unikezelwa ngokugqitywa okusemgangathweni.Kwiimeko ezinjalo, umsebenzi owongezelelweyo womatshini wenziwa ukunciphisa uburhabaxa bomhlaba kwixabiso elamkelekileyo.Kwiindawo ezenziwe ngoomatshini be-CNC, imisebenzi enjalo inokongezwa kwinkqubo yokuvelisa ukugcina ixesha.Kwiindawo eziveliswe ngoomatshini abangeyiyo i-CNC okanye oomatshini abaninzi, umatshini we-CNC usetyenziselwa umatshini ogudileyo emva kokuphela kwemveliso kwaye inxalenye ilungile.
