Ukukhetha isixhobo sokusika

Ukukhethaumsiki wokugayaAsingomsebenzi ulula. Zininzi izinto eziguquguqukayo, izimvo kunye neengcamango ekufuneka ziqwalaselwe, kodwa ngokuyintloko ingcali yemishini izama ukukhetha isixhobo esiya kunciphisa izinto ngokweemfuno ezifunekayo ngexabiso eliphantsi. Ixabiso lomsebenzi lidibaniso lexabiso lesixhobo, ixesha elithathwa yiumatshini wokugaya,kunye nexesha elithathwa yingcali yoomatshini. Rhoqo, kwimisebenzi enamalungu amaninzi, kunye neentsuku zexesha loomatshini, ixabiso lesixhobo liphantsi kakhulu kwiindleko ezintathu.

• Izixhobo:Izicucu zentsimbi ekhawulezayo (HSS) zezona zicucu ezingabizi kakhulu kwaye zihlala ixesha elifutshane. Iintsimbi ezikhawulezayo ezineCobalt zihlala zisebenza nge-10% ngokukhawuleza kunentsimbi eqhelekileyo ekhawulezayo. Izixhobo ze-carbide ezenziwe ngesamente zibiza kakhulu kunentsimbi, kodwa zihlala ixesha elide, kwaye zinokusebenza ngokukhawuleza kakhulu, ngoko ke zibonakalise zingabizi kakhulu ekuhambeni kwexesha.Izixhobo ze-HSSzanele ngokupheleleyo kwiindlela ezininzi zokusetyenziswa. Ukuqhubela phambili ukusuka kwi-HSS eqhelekileyo ukuya kwi-cobalt HSS ukuya kwi-carbide kunokubonwa njengento elungileyo kakhulu, engcono nangakumbi, kwaye yeyona ilungileyo. Ukusebenzisa ii-spindles ezinesantya esiphezulu kunokuthintela ukusetyenziswa kwe-HSS ngokupheleleyo.
• Ububanzi:Izixhobo ezinkulu zinokususa izinto ngokukhawuleza kunezincinci, ngoko ke kukhethwa isixhobo esikhulu esiza kufaneleka emsebenzini. Xa kugaywa i-contour yangaphakathi, okanye i-concave yangaphandle, ububanzi bunqunyelwe bubungakanani bee-curves zangaphakathi. I-radius yeumsikikufuneka ibe ngaphantsi okanye ilingane nerediyasi ye-arc encinci.
• Iiflute:Iiflute ezininzi zivumela izinga eliphezulu lokutya, kuba akukho zinto zininzi ezisuswayo kwiflute nganye. Kodwa ngenxa yokuba ububanzi be-core buyanda, akukho ndawo ingako yokufunxa, ngoko ke kufuneka kukhethwe ibhalansi.
• Ukwaleka:Iingubo ezifana ne-titanium nitride nazo zonyusa iindleko zokuqala kodwa zinciphisa ukuguguleka kwaye zonyusa ubomi besixhobo.Ukwaleka kweTiAlNkunciphisa ukunamathela kwe-aluminium kwisixhobo, kunciphisa kwaye ngamanye amaxesha kuphelisa imfuneko yokuthambisa.
• I-engile ye-Helix:Ii-angles eziphezulu ze-helix zihlala zilungele iintsimbi ezithambileyo, kunye nee-angles eziphantsi ze-helix kwiintsimbi eziqinileyo okanye ezinzima.
