Kwa munthu wosaphunzitsidwa bwino, rotary burr ingawoneke ngati chitsulo chosavuta. Komabe, magwiridwe ake ndi chifukwa cha sayansi ya zinthu zamakono. Mawu akuti "tungsten carbide" amatanthauza chinthu chophatikizika, cermet, komwe tinthu ta tungsten carbide tolimba kwambiri timalumikizidwa pamodzi ndi chomangira chachitsulo chosungunuka, chomwe nthawi zambiri chimakhala cobalt. Mtundu wake, monga YG8, ndiye njira yachinsinsi yomwe imalamulira magwiridwe antchito a chidacho.
YG8 imatanthauza kapangidwe ka 92% ya tungsten carbide ndi 8% ya cobalt polemera. Chiŵerengero ichi sichinthu chokhazikika. Tungsten carbide imapereka kuuma kwakukulu - nthawi zambiri kumayesa pafupifupi 90 HRA pa sikelo ya Rockwell - komwe ndikofunikira pakukumba ndi kudula zinthu zina zolimba. Kuuma kumeneku ndiko komwe kumalolachozungulira cha fayilo ya carbide burrkupukusa mosavuta chitsulo chosapanga dzimbiri ndi chitsulo chopangidwa popanda kuuma msanga.
Komabe, kuuma kokha sikokwanira. Chipangizo cholimba kwambiri chingakhale chophwanyika komanso chosavuta kusweka kapena kulephera kwakukulu chifukwa cha kupsinjika kwa mbali ya kugaya. Apa ndi pomwe cobalt binder imabwera. Cobalt imawonjezera kulimba ndi kukana kugwedezeka, kulola mutu wopera kuyamwa kugunda ndi kugwedezeka kwa njira yopangira popanda kusweka. 8% ya cobalt mu YG8 ndi njira yapamwamba kwambiri yopangidwira kulinganiza bwino; imapereka kukana kwabwino kwambiri (ngakhale kocheperako pang'ono kuposa cobalt yotsika ngati YG6) pomwe imapereka mphamvu komanso kukana kugwedezeka bwino kwambiri, zomwe zimapangitsa kuti ikhale yabwino kwambiri.
Mbiri yabwinoyi ya nyumba ndiye chifukwa chake chitsulo cha YG8 tungstenmutu woperaanganene kuti ndi osinthasintha kwambiri. Ndikokwanira kuthana ndi kudula kosalekeza komanso kugwedezeka komwe kungachitike chifukwa chogwira ntchito pa zinthu zosakanikirana ndi chitsulo chopangidwa ndi chitsulo kapena malo osafanana. Nthawi yomweyo, zimakhala zovuta kusunga m'mphepete mwa kukhudza zinthu zokwawa monga chitsulo chosapanga dzimbiri, zomwe zimagwira ntchito molimbika panthawi yopangira.
Kumvetsetsa sayansi iyi kumathandiza ogwiritsa ntchito kusankha chida choyenera pantchitoyo. Pofuna kudula mosalekeza zinthu zofanana komwe kukana kuwonongeka kwambiri ndikofunikira, mtundu wotsika wa cobalt ungasankhidwe. Koma pazinthu zambiri zomwe zimagwiritsidwa ntchito, kuphatikizapo kukonza chitsulo, chitsulo, mkuwa, ndi aluminiyamu, YG8 ikuyimira muyezo wagolide wa magwiridwe antchito ndi kulimba. Ndi luso lazinthu izi lomwe limasintha chida chosavuta kukhala chida cholondola chomwe chingathe kugwira chilichonse kuyambira ntchito zachitsulo zamafakitale mpaka chosema mwala ndi fupa.
Kuwunikira Zamalonda: Dziwani bwino kuuma ndi kulimba ndi ma rotary burrs athu, opangidwa kuchokera ku YG8 tungsten steel. Fayilo yozungulira iyi imatha kukonza chitsulo, chitsulo chopangidwa ndi chitsulo, chitsulo chonyamula, chitsulo cha carbon yambiri, chitsulo chosakanikirana, chitsulo chosapanga dzimbiri, mkuwa, aluminiyamu, komanso zinthu zina zopanda zitsulo monga marble, jade, ndi fupa.
