Iimbonakalo:
Ukuchaneka okuphezulu: emva konyango oluchanekileyo lokusila, i-bore diameter kunye ne-surface roughness kulawulwa ngokungqongqo ukuqinisekisa imilinganiselo echanekileyo kunye neempawu zejometri.
I-Smooth surface: emva kokusila unyango, umphezulu webhorethi ulula, unciphisa ukukhuhlana kunye nokugqoka, okunenzuzo ekuhanjisweni kwamanzi kunye nokusebenza kwenkqubo.
IiPropati eziPhakamileyo zoomatshini: Iityhubhu zentsimbi ezibhodloze umhlaba zihlala zineempawu ezingcono zoomatshini kunye nobomi bokudinwa ngenxa yokukhululeka koxinzelelo ngexesha lenkqubo yokusila.
Ukulungiswa kakhulu: iinketho ezilungiselelwe ziyafumaneka kwizinto ezahlukeneyo, ubungakanani, ukuchaneka kwedayamitha kunye noburhabaxa bomphezulu ngokweemfuno zabathengi.
