Kala-saarista

Xajmiga waxa loo kala saaraa ugu horrayn afar qaybood: xadhkaha rogroga, xadhkaha cad, xagasha xagasha, iyo is{0}is toosinta kubbadaha. Xirmooyinka duuban waxay isticmaalaan curiyeyaasha duuban (sida rollers iyo kubbadaha birta) si ay u yareeyaan is jiid jiid waxayna ku habboon yihiin -xawaaraha sare, sare{3}} codsiyada rarka. Tusaale ahaan, kubbadda jeexjeexa qoto dheer (oo leh xawaare ilaa 20,000 rpm) ayaa loo adeegsadaa matoorada baabuurta, halka rullaluistuyada duuban (oo leh 30% korodhka awoodda culeyska) ay ku habboon yihiin mashiinnada culus. Gawaarida bannaanka ah waxaa laga soo dhisey agab hoose{9}}(sida aluminium naxaas ah iyo polytetrafluoroethylene). Xadhkaha gacmaha ee graphite waa kulayl{11}} adkaysi u leh (heerkulka shaqaynta In ka yar ama la mid ah 500 digrii). Dareere -Xidhiyeyaasha saliidaysan waxay gaadhaan ultra{15}} khilaaf hoose (isku xidhka is jiid jiid <0.001) iyadoo la adeegsanayo filim saliid ah, taasoo ka dhigaysa inay ku habboon yihiin aaladaha saxda ah. Xadhkaha xidhiidhka xagaluhu waxay u adkeysan karaan labada xagood ee radiyaalka iyo axial (xalaha xidhiidhka ee 15 darajo -40 darajo) waxaana si weyn loogu isticmaalaa isbinaajyada qalabka mashiinka. Nafta{22}Isku toosinta xadhkaha kubbada waxay ka kooban tahay hawl is toosin ah (oo leh xagal magdhaw ah 2 darajo -3 darajo) waxayna ku habboon yihiin bay'adaha gariiraya sida mishiinada macdanta.
