Emehlweni angakaqeqeshwa, i-rotary burr ingase ibukeke njengengcezu yensimbi elula. Kodwa-ke, ukusebenza kwayo kuwumphumela oqondile wesayensi yezinto eziyinkimbinkimbi. Igama elithi "tungsten carbide" ngokwalo libhekisela ezintweni ezihlanganisiwe, i-cermet, lapho izinhlayiya ze-tungsten carbide eziqinile kakhulu zihlanganiswa khona nge-ductile metal binder, ngokuvamile i-cobalt. Ibanga elithile, njenge-YG8, liyindlela eyimfihlo elawula ukusebenza kwethuluzi.
I-YG8 isho ukwakheka kwe-tungsten carbide engu-92% kanye ne-cobalt engu-8% ngesisindo. Lesi silinganiso asinqunyelwe. I-tungsten carbide inikeza ubulukhuni obukhulu—ngokuvamile obulinganisa cishe ama-HRA angu-90 esikalini se-Rockwell—okubalulekile ekugubungeni nasekusikeni ezinye izinto eziqinile. Lobu bulukhuni yibo obuvumelai-carbide burr rotary file bitukugaya kalula insimbi engagqwali kanye nensimbi ephonswe ngaphandle kokubuthuntuza ngokushesha.
Kodwa-ke, ubulukhuni bodwa abwanele. Izinto eziqinile kakhulu zingaba buthakathaka futhi zithambekele ekuqhekekeni noma ekuhlulekeni okukhulu ngaphansi kwengcindezi eseceleni yokugaya. Yilapho i-cobalt binder ingena khona. I-Cobalt yengeza ukuqina nokumelana nokushaqeka, okuvumela ikhanda lokugaya ukuthi limunce imiphumela nokudlidliza kwenqubo yokugaya ngaphandle kokuqhekeka. Okuqukethwe kwe-cobalt okungu-8% ku-YG8 kuyindlela esezingeni eliphezulu eyenzelwe ibhalansi ephelele; inikeza ukumelana nokuguguleka okuphezulu (nakuba kungaphansi kancane kwebanga le-cobalt eliphansi njenge-YG6) ngenkathi inikeza amandla athuthukisiwe kakhulu nokumelana nomthelela, okwenza kube yinto enhle kakhulu.
Le phrofayili yempahla elinganiselayo yingakho insimbi ye-YG8 tungstenikhanda lokugayaKungathi kunokuguquguquka okukhulu kangaka. Kunzima ngokwanele ukubhekana nokusika okuvamile kanye nokushaqeka okungenzeka kokusebenza ezintweni ezifakwe ensimbini noma ezindaweni ezingalingani. Ngesikhathi esifanayo, kunzima ngokwanele ukugcina umkhawulo wokusika obukhali ngokuxhumana isikhathi eside nezinto ezihudulayo njengensimbi engagqwali, ezisebenza kanzima ngesikhathi somshini.
Ukuqonda le sayensi kusiza abasebenzisi ukuthi bakhethe ithuluzi elifanele lomsebenzi. Ukuze kunqunywe njalo ezintweni ezifanayo lapho ukumelana nokuguguleka okuphezulu kubalulekile, kungase kukhethwe izinga eliphansi le-cobalt. Kodwa ngobuningi bezicelo ezijwayelekile, okuhlanganisa ukucutshungulwa kwensimbi, insimbi, ithusi, ne-aluminium, i-YG8 imelela izinga legolide lokusebenza nokuqina. Yilokhu kusungula izinto ezintsha okuguqula ithuluzi elilula libe ithuluzi elinembile elikwazi ukuphatha yonke into kusukela ekusebenzeni kwensimbi yezimboni kuya ekuqopheni okubucayi kwetshe nethambo.
Ukukhanya Komkhiqizo: Thola ibhalansi ephelele yokuqina nokuqina ngama-rotary burrs ethu, enziwe ngensimbi ye-YG8 tungsten. Leli fayela elijikelezayo liyakwazi ukucubungula insimbi, insimbi ehlanganisiwe, insimbi ethwala, insimbi enekhabhoni ephezulu, insimbi ye-alloy, insimbi engagqwali, ithusi, i-aluminium, kanye nezinsimbi ezingezona ezensimbi njengemabula, i-jade, nethambo.
