Kwinyanga ephelileyo, umthengi wasifumana ngelixa efuna indlela yokucheba umphetho we-zinc alloy. Impendulo yethu yayiyeyokwenene, kodwa ngenxa yesimo kunye nomahluko ngamnye ekubunjweni kweemveliso, isiphumo sokucheba kuya kufuneka sivavanywe ngaphambi kokuba siboniswe kumthengi.
Emva kokufumana umbhobho wokudibanisa we-zinc alloy, sakhawuleza savavanya ii-burrs ezikwi-joint saza safumanisa ukuba umbhobho wawudityaniswe kwi-joint kwaye wawungenakwahlulwa. Ke ngoko, zombini kwafuneka zifakwe kumatshini wokusika obandayo ukuze kuncitshiswe umphetho. Ubukhulu bee-burrs babuphakathi kwe-0.21 ukuya kwi-1.97mm njengoko kubonwe phantsi kwe-electron microscope, kwaye ii-burrs nazo zazibonakala ngokucacileyo emehlweni.
Ngenxa yeempawu zezinto ze-zinc alloy, sisebenzisa umatshini okhusela ukuqhuma we-MG ukukhupha umbane. Le modeli iphuculwe ngokusekelwe kwimodeli esisiseko ngolu hlobo lulandelayo:
1. Izinto ezijikeleze izixhobo zinyangwa ukuba zingaqhumi, kwaye kukho umoya wokhuseleko wokunciphisa uxinzelelo phezulu.
2. Ucango lwegumbi lezixhobo luxhotyiswe ngentonga ekhethekileyo yokumelana noxinzelelo lokuqhuma.
Umbhobho odibeneyo we-zinc alloy, emva kokuba ulungiswe ngomatshini wokukhupha umbane obizwa ngokuba yi-cryogenic deflashing, wawususwe ii-burrs ezinkulu ezibonakalayo, kwaye xa zikhuliswa izihlandlo ezingama-30 phantsi kwe-electron microscope, ii-burrs ezincinci eziseleyo zaziphantsi njenge-0.06mm, ngaphakathi koluhlu olufunekayo kumthengi. Iziphumo zovavanyo bezilungile, kwaye imveliso ngoku ithunyelwe kumthengi ukuze kuvavanywe ukusebenza ngakumbi.
