Nk’uko izina ribigaragaza, ibicuruzwa bya grafiti ni ubwoko bwose bw’ibikoresho bya grafiti n’ibicuruzwa bya grafiti bifite imiterere yihariye bitunganywa n’ibikoresho bya CNC bishingiye ku bikoresho fatizo bya grafiti, harimo grafiti crucible, graphite plate, grafiti rod, grafiti mold, graphite heater, graphite box, grafiti rotor n’ibindi bikoresho bya grafiti.
Muri iki gihe, ibikoresho bya grafiti bikoreshwa cyane mu nganda zikora rukuruzi zihoraho z’ubutaka. Ibikoresho by’ingenzi bya grafiti bikoreshwa muri uru rwego ni udusanduku twa grafiti two gusya, tuzwi kandi nka cartridge y’amabuye, ubwato bwa grafiti n’ibindi.
Mbere na mbere, reka tubanze tumenyeshe icyo ibikoresho bya rukuruzi ihoraho ya rare earth ari cyo, hamwe n'ikoreshwa n'imikoreshereze y'ibikomoka kuri grafiti byayo mu gukora uru rwego. Ibintu bya rukuruzi ihoraho ya rare earth ni ubwoko bw'ibikoresho bya rukuruzi, bikozwe mu cyuma cya samariyumu kigizwe na samarium, neodymium mixed rare earth metal n'icyuma gihinduka (nka cobalt, icyuma, nibindi), bicukurwa hakoreshejwe uburyo bwa powde metallurgy kandi bigakururwa na rukuruzi. Ibikoresho bya rukuruzi ihoraho ya rare earth bigabanyijemo SmCo permanent magnet na NdFeB permanent magnet. Muri byo, ingufu rukuruzi zikomoka kuri SmCo magnet ziri hagati ya 15-30 mgoe, naho iza NdFeB magnet ziri hagati ya 27-50 mgoe, ari byo byitwa "umwami wa rukuruzi ihoraho". Samarium cobalt permanent magnet, nubwo ifite ubushobozi bwiza bwa rukuruzi, irimo samarium na cobalt, ari byo bita cobalt idasanzwe kandi ihenze cyane. Kubwibyo, iterambere ryayo ryagabanijwe cyane. Nyuma y’imyaka myinshi y’ingamba z’abashakashatsi mu bya siyansi mu Bushinwa, leta yashoye amafaranga menshi mu nganda, kandi ibikoresho bishya bya magnetism bihindagurika mu buryo bw’ubutaka budasanzwe n’icyuma gisanzwe cya azote kirimo guterwa imbere, birashoboka kuba igisekuru gishya cya magnetism ihoraho ya shimi idasanzwe. Gukora ibikoresho bya magnetism bigomba gukoresha icyuma cya graphite kugira ngo gisukurwe ku bushyuhe bwinshi mu itanura rikoresha umwuka. Ibikoresho bya magnetism bihoraho bifatanye n’ubuso bw’imbere bw’icyuma cya graphite ku bushyuhe bumwe, kandi ibikoresho bya magnetism bihoraho bikenewe n’ibyuma bihoraho bya magnetism biratunganywa burundu.
Nk’uruganda rukora ibikoresho bya grafiti, agasanduku ka grafiti (grafiti ark, grafiti cartridge) gakorwa na Zhonghong ibikoresho bishya bikoreshwa cyane mu nganda zikora magneti zihoraho za rare earth, kandi abakiriya barashimwe kandi bashyiraho ubufatanye burambye!
