1. Ubulukhuni obuphezulu
Inzuzo eyinhloko yeamasondo okugaya afakwe ngogesiubulukhuni bazo obuphezulu. Lokhu kungenxa yokuthi isibopho sensimbi esifakwe ngogesi esisetshenziswa ukwenza leli sondo ngokuvamile senziwe nge-nickel noma i-nickel-cobalt alloy. Lesi sibophezeli sinesakhiwo esiqinile esithuthukisa isibopho kanye nobunzima obuphelele. Amasondo okugaya afakwe ngogesi ahlinzeka ngobulukhuni obuphezulu kakhulu kune-bronze ne-resin abrasives. Ukwakhiwa okuhlangene kwamasondo okugaya afakwe ngogesi kunikeza izinzuzo ezingaphezu kobulukhuni. Uma esetshenziselwa ukugaya, lawa masondo anikeza ukuzinza okungcono ngoba izinhlamvu zawo ezithambile zinamathele ngokuqinile ku-substrate yensimbi. Lokhu kuqinisekisa ukuthi isondo lokugaya likhiqiza imiphumela efanayo ngisho nangaphansi kokucindezeleka okuphezulu. Ngaphezu kwalokho, lesi sici sisiza ukwandisa impilo yesondo lokugaya.
2. I-porosity ephansi kakhulu
Esinye isici esenza amasondo okugaya afakwe ngogesi ahluke kwamanye asekilasini lawo ukuthi anezimbobo eziphansi kakhulu kunanoma yiliphi ithuluzi elikhuhlayo.
Ukugoba kuyisilinganiso sokuthi zingaki izikhala ezikhona ngaphakathi kwento ethile. Ukugoba kwesondo lokugaya kungaba nomthelela omkhulu ekusebenzeni kahle nasekuqineni kwethuluzi. Isibonelo, amasondo okugaya avamile aqoshwe nge-sinter angaba nokugoba okuphezulu okufika kumaphesenti ayishumi, okunciphisa ukusebenza kwawo kahle. I-resin noma i-bronze-bond abrasives nayo inezimbobo eziphakeme kunemikhiqizo efakwe i-plated.
Ngakolunye uhlangothi, ukuvuleka kwamasondo okugaya afakwe ngogesi cishe ku-zero. Lokhu kuwenza abe amathuluzi aqinile nathembekile kakhulu embonini. Ukuvuleka okuphansi kwamasondo okugaya afakwe ngogesi nakho kuyazuzisa uma ucabangela ukuqina kwawo. Amathuluzi okugaya anamandla aphezulu kanye nokuqina abalulekile lapho ugaya izinto ezahlukahlukene. Amasondo okugaya afakwe ngogesi cishe awanama-porosity futhi anikeza amandla aphezulu kanye nokuqina, okwenza afaneleke kakhulu ekusetshenzisweni kokugaya okudinga ukunemba nokunemba. Ngokungafani namasondo acwebezelayo, anezimbobo ezivulekile, amasondo afakwe ngogesi ahlanganiswe ngokuphelele ngensimbi. Lokhu kusho ukuthi izinhlayiya ezihlanganisiwe ezihlanganisiwe ziboshwe ngqo ku-substrate yensimbi. Lokhu kuphumela ekusabalalisweni okulinganayo kwezinhlayiya eziqhekekayo kulo lonke isondo, okwenza likwazi ukukhiqiza imiphumela ehambisanayo ngokusetshenziswa ngakunye. Ukuvuleka okuphansi kwamasondo afakwe ngogesi nakho kusiza ekuqedeni izinkinga zokuvaleka. Ukuvaleleka kwenzeka lapho isondo line-porosity eningi kakhulu, okuholela ekuqongeleleni kwemfucumfucu eqhekekayo ebizwa ngokuthi i-swarf. Lokhu kungathinta kakhulu ukusebenza kwethuluzi. Amasondo okugaya afakwe ngogesi aklanyelwe ukuvimbela ukuvaleka ngokunikeza isibopho esiqinile, esifanayo, ukuqinisekisa ukuthi ama-chips asuswa ebusweni bokugaya.
3. Inhlanganisela enamandla kakhulu
Inzuzo ebalulekile yamasondo okugaya idayimane afakwe ngogesi ukubopha okuqinile phakathi kwensimbi nezinto ezihudulayo. Isibopho sensimbi esendlaleloni yokusebenza sifakwe kakhulu enhlabathini, okudala isibopho esiqinile futhi esihlala isikhathi eside kunezinye izinhlobo zamasondo. Lokhu kuhlanganiswa kuqinisekisa ukuxhumana okwanele phakathi kwe-abrasive kanye ne-workpiece, okuholela enqubweni yokugaya esebenza kahle kakhulu. Ukuhlanganiswa kwesendlalelo sokusebenza esiboshwe ngensimbi nakho kunamandla, okusho amandla aphezulu okubamba. Lo msebenzi ubalulekile lapho kugaywa izinto ezinobunzima obuhlukene.
Amasondo edayimane afakwe ngogesi angaphatha amazinga aphezulu okushisa, okwenza abe afanelekele ukugaya izinsimbi eziqinile njenge-tungsten carbide. Ngamandla ayo aphezulu okugcina, izinto ezihudulayo ngeke ziwe ngaphambi kwesikhathi, okwenza zingalingani nokubunjwa kwempuphu.
4. Ukuhlushwa okuphezulu kakhulu
Kumasondo okugaya enziwe ngempuphu, ukuhlushwa okubukhali kusendlalelo sokusebenza ngokuvamile kungu-50% kuya ku-150%, kanti ivolumu yokuhlushwa ingu-10% kuya ku-30%. Ukuhlushwa okubukhali kwesondo lokugaya idayimane elifakwe ngogesi cishe kungu-200%, kanti ivolumu yokuhlushwa ingafinyelela ngaphezu kuka-65%. Lokhu kuhlushwa okuphezulu kwezinto ezihlushwayo kwandisa kakhulu impilo yesevisi futhi kuthuthukisa ukusebenza okuhlushwayo. Ukuhlushwa okuphezulu kwezinto ezihlushwayo kumasondo okugaya idayimane afakwe ngogesi kungenxa yenqubo yokukhiqiza ehlukile.
Uma kuqhathaniswa namasondo okugaya endabuko akhiwe ngokuxuba izinhlamvu ezihudulayo nge-binder bese ecindezelwa abe yisimo, amasondo okugaya edayimane afakwe ngogesi akhiqizwa ngokufaka ungqimba lwezinhlamvu zedayimane ku-substrate yensimbi. Le nqubo iqinisekisa ukuthi izinhlayiya zedayimane zisatshalaliswa ngokulinganayo futhi zinamathele ngokuqinile ku-substrate yensimbi, okudala isibopho esiqinile sokusebenza kahle okukhulu ngesikhathi sokugaya.
Ngaphezu kwalezi zinzuzo ezine, amasondo okugaya idayimane afakwe ngogesi anezinye izinzuzo eziningana.
Okokuqala, ziqinile kakhulu futhi zingamelana namazinga okushisa aphezulu kanye nezingcindezi ngaphandle kokulahlekelwa ubuqotho noma ukuma kwazo. Ziphinde zinikeze indawo yokugaya ehlanzekile nenembile, okwenza zibe amathuluzi afanele ukusetshenziswa komshini wokugaya ngokunemba. Enye inzuzo yamasondo okugaya edayimane afakwe ngogesi ukuthi asebenza ngezindlela eziningi. Angasetshenziswa ezintweni ezahlukahlukene, kufaka phakathi izinto eziqinile njenge-tungsten carbide kanye ne-ceramics. Lokhu kusebenza ngezindlela eziningi kuzenza zibe ukukhetha okuthandwayo ezimbonini eziningana kufaka phakathi izimoto, izindiza kanye ne-elekthronikhi.
