Kwiliso elingaqeqeshwanga, i-rotary burr ingabonakala ngathi yintsimbi nje. Nangona kunjalo, ukusebenza kwayo kubangelwa yisayensi yezinto ezintsonkothileyo. Igama elithi "tungsten carbide" ngokwalo libhekisa kwizinto ezidityanisiweyo, i-cermet, apho amasuntswana e-tungsten carbide aqinileyo kakhulu adityaniswa yi-ductile metal binder, edla ngokuba yi-cobalt. Uhlobo oluthile, olufana ne-YG8, yindlela eyimfihlo yokulawula ukusebenza kwesixhobo.
I-YG8 imele ukwakheka kwe-92% ye-tungsten carbide kunye ne-8% ye-cobalt ngobunzima. Olu linganiselo aluxhomekekanga. I-tungsten carbide inika ubunzima obukhulu—okudla ngokuba nomlinganiselo omalunga ne-90 HRA kwisikali seRockwell—obubalulekileyo ekuqhekezeni nasekusikeni ezinye izinto eziqinileyo. Obu bunzima buvumelai-bit yefayile ye-carbide burr ejikelezayoukucola intsimbi engenasici kunye nentsimbi ephoswe ngaphandle kokukhawuleza ibuthuntu.
Nangona kunjalo, ubulukhuni bodwa alwanelanga. Izinto eziqinileyo kakhulu zinokuba buthathaka kwaye zikwazi ukuqhekeka okanye ukusilela okukhulu phantsi koxinzelelo olusecaleni lokusila. Kulapho i-cobalt binder ingena khona. I-Cobalt yongeza ubulukhuni kunye nokumelana nokutshaqeka, ivumela intloko yokusila ukuba ifunxe iimpembelelo kunye nokungcangcazela kwenkqubo yokugaya ngaphandle kokuqhekeka. Umxholo we-cobalt we-8% kwi-YG8 yifomyula yekhwalithi ephezulu eyenzelwe ukulinganisela okugqibeleleyo; inika ukumelana nokuguguleka okuphezulu (nangona ingaphantsi kancinci kune-cobalt esezantsi njenge-YG6) ngelixa inika amandla aphuculweyo kunye nokumelana nempembelelo, okwenza ukuba ibe yeyona igqwesileyo kuzo zonke izinto.
Le propati ilinganisiweyo yiyo kanye le nto ibangela ukuba intsimbi ye-YG8 tungsten ibe yintsimbi.intloko yokusilaunokuthi uyakwazi ukuguquguquka kakhulu. Kunzima ngokwaneleyo ukujongana nokusikwa okwethutyana kunye nokuphazamiseka okunokwenzeka kokusebenza kwizinto ezifakwe kwisinyithi okanye kwiindawo ezingalinganiyo. Kwangaxeshanye, kunzima ngokwaneleyo ukugcina umphetho obukhali wokusika ngokudibana ixesha elide nezinto ezirhabaxa ezifana nentsimbi engagqwaliyo, ezisebenza nzima ngexesha lokwenziwa.
Ukuqonda le sayensi kunceda abasebenzisi ukuba bakhethe isixhobo esifanelekileyo somsebenzi. Ukuze kuqhubeke ukusika izinto ezifanayo apho ukumelana nokuguguleka okuphezulu kubalulekile, kukhethwe umgangatho we-cobalt ophantsi. Kodwa uninzi lwezicelo ezisetyenziswa ngokubanzi, kubandakanya ukucutshungulwa kwesinyithi, isinyithi, ubhedu, kunye ne-aluminium, i-YG8 imele umgangatho wegolide wokusebenza kunye nokuqina. Yile nto intsha eguqula isixhobo esilula sibe sisixhobo esichanekileyo esikwaziyo ukuphatha yonke into ukusuka ekusebenzeni ngesinyithi kwimizi-mveliso ukuya ekuqoshweni okuthambileyo kwelitye kunye nethambo.
Ingqwalasela yeMveliso: Fumana ibhalansi egqibeleleyo yobunzima kunye nokuqina ngee-rotary burrs zethu, ezenziwe ngentsimbi ye-YG8 tungsten. Le fayile ye-rotary iyakwazi ukucubungula isinyithi, isinyithi esityhidiweyo, isinyithi esithwalayo, isinyithi esinekhabhoni ephezulu, isinyithi se-alloy, isinyithi esingenasici, ubhedu, i-aluminium, kunye nezinye izinto ezingezizo iimetali ezifana ne-marble, i-jade, kunye nethambo.
