Ho hlahisa boqapi ba morao-rao ba sehlahisoa sa merafo le ho cheka - Diamond Composite Gear (DEC)! Sehlahisoa sa rona sa DEC se kopanya lisebelisoa tse ntle ka ho fetisisa tsa daemane le tse kopantsoeng ho u fa lisebelisoa tse phahameng tsa ho cheka tse fetang tebello ea hau.
Meno a rona a DC1924 a sephara a daemane a sephara a chesitsoe ka mocheso o phahameng haholo le likhatello ho theha meno a thata le a tšoarellang a ka mamellang mathata a ho rafa le ho cheka. Mekhoa ea tlhahiso e tšoana le ea lipoleiti tse kopantsoeng tsa taemane, e netefatsang botsitso le ts'epahalo ho meno 'ohle a rona a motsoako oa litaemane.
Meno a kopantsoeng a hanyetsana le tšusumetso e matla 'me a loketse ho sebelisoa libopong tsa PDC (polycrystalline diamond compact) le libopo tse theohileng tlase. Meno a rona a kopantsoeng a entsoe ho nka sebaka sa lihlahisoa tsa carbide, tse tsebahalang ka ho hlaka le bophelo bo fokolang ba ts'ebeletso. Ka lebaka leo, lihlahisoa tsa rona tsa DEC li tšoarella nako e telele, li u bolokela nako le chelete ha nako e ntse e ea.
