isiphelo sokusila

Ziziphi izixhobo eziqhelekileyo zokugaya izixhobo?

Izixhobo eziqhelekileyo zesixhobo kwisixhobo sokusila ziquka isinyithi esinesantya esiphezulu, i-metallurgy ye-powder high-speed steel, i-alloy eqinile, i-PCD, i-CBN, i-cermet kunye nezinye izinto ezinzima kakhulu. Izixhobo zentsimbi zesantya esiphezulu zibukhali kwaye zinobulukhuni obuhle, ngelixa izixhobo ze-carbide zinobulukhuni obuphezulu kodwa zinzima. Ubuninzi besixhobo se-carbide NC ngokucacileyo buphezulu kuneso sixhobo sensimbi esinesantya esiphezulu. Ezi zixhobo zimbini zezona zinto ziphambili kwi-drills, i-reamers, i-milling inserts kunye neetephu. Ukusebenza komgubo wesinyithi esinesantya esiphezulu kuphakathi kwezi zinto zimbini zingasentla, ezisetyenziswa ikakhulu ukwenza umsiki wokusila kunye nempompo.

Izixhobo zentsimbi ezikhawulezayo azikhathaleli ukungqubana ngenxa yokuqina kwazo okuhle. Nangona kunjalo, i-carbide NC blade iphezulu ngobulukhuni kunye ne-brittle, i-ecative kakhulu ekungqubekeni, kwaye umgca kulula ukutsiba. Ngoko ke, kwinkqubo yokugaya, ukusebenza kunye nokubekwa kwezixhobo ze-carbide eziqiniweyo kufuneka ziqaphele kakhulu ukukhusela ukungqubana phakathi kwezixhobo okanye ukuwa kwezixhobo.

Ngenxa yokuba ukuchaneka kwezixhobo zensimbi ezinesantya esiphezulu kuncinci, iimfuno zabo zokusila azikho phezulu, kwaye amaxabiso azo akaphezulu, abaninzi abavelisi bamisela izixhobo zabo zokusebenzela zokuzisila. Nangona kunjalo, izixhobo ze-carbide zesamente zihlala zifuna ukuthunyelwa kwiziko lokugaya elichwephesha lokugaya. Ngokwezibalo zamaziko athile okugaya izixhobo zasekhaya, ngaphezu kwe-80% yezixhobo ezithunyelwe ukulungiswa zizixhobo ze-carbide ezifakwe ngesamente.
