I-Tungsten Carbide Milling Cutter

   Kukhona uhlobo lwethuluzi lokusika elinamandla kakhulu, kungakhathaliseki ukuthi indiza ethwala emanzini noma indiza yokulwa esibhakabhakeni, noma iWebb Space Telescope esanda kwethulwa ebiza amaRandi ayizigidi eziyizinkulungwane ezingu-10, konke kudingeka kucutshungulwe yiyo. Kuyi-tungsten steel milling cutter. Insimbi ye-Tungsten ilukhuni kakhulu futhi iwuhlobo lwensimbi olunzima kunazo zonke olukhiqizwa ukukhiqizwa kobuningi okwenziwa ngesandla. Ingakwazi ukucubungula cishe zonke izinsimbi ngaphandle kwekhabhoni. I-Non steel, eyaziwa nangokuthi i-hard alloy, yakhiwa ikakhulukazi ama-carbides ne-cobalt sintered. I-tungsten carbide powder incibilikiswa ku-tungsten ore. I-China iyizwe elikhulu kunawo wonke emhlabeni elinezimayini ze-tungsten, ibalwa ku-58% weziqiwi eziqinisekisiwe ze-tungsten.

    Indlela yokukhiqiza ama-tungsten steel milling cutters? Namuhla, ubuchwepheshe be-powder metallurgy busetshenziswa kakhulu. Okokuqala, insimbi ye-tungsten yenziwa ibe yimpuphu ye-tungsten, bese impushana icindezelwa esikhunjini esiklanywe umshini. Umshini wokugaya onesisindo esingamathani ayi-1000 usetshenziselwa ukucindezela. I-Tungsten powder ivame ukwakhiwa ngendlela esezingeni eliphezulu yokucwiliswa okulinganayo. Ukungqubuzana phakathi kwempushana nodonga lwesikhunta kuncane, futhi i-billet ingaphansi kwamandla afanayo kanye nokusatshalaliswa kokuqina. Ukusebenza komkhiqizo kuthuthukiswa kakhulu.

  I-tungsten steel milling cutter iyisilinda, ngakho-ke insimbi ye-tungsten ecindezelwe iyisilinda. Ngalesi sikhathi, insimbi ye-tungsten iyi-powder block ehlanganiswe ndawonye ngamapulasitiki, bese idinga ukucwiliswa.

  Lesi isithando somlilo esikhulu somlilo esishaja izinti zempushana ye-tungsten ecindezelwe futhi iwasunduze ukuze ashisise aze ancibilike ezingxenyeni eziyinhloko, aguqule amaqoqo ezinhlayiya zempushana zibe ukuhlakazeka kwezinhlamvu.

  Ukucacisa kakhudlwana, okokuqala, ngemuva kokudubula kwangaphambi kokushisa okuphansi, i-ejenti yokubumba iyasuswa futhi i-crystallization ixoshwa ekushiseni okuphakathi ukuze kuqedelwe inqubo ye-sintering ekushiseni okuphezulu. Ubuningi bomzimba we-sintered buyanda, futhi ngesikhathi sokupholisa, amandla aqoqwa ukuze kutholwe izakhiwo ezidingekayo zomzimba nemishini yezinto. I-Sintering iyinqubo ebaluleke kakhulu ku-powder metallurgy.

Susa ingxubevange yensimbi ye-tungsten epholile ekamelweni lokushisa futhi uqhubekele esinyathelweni esilandelayo sokugaya okungenaziko. Ukugaya okungenanhliziyo kuyinqubo yokupholisha, lapho ingaphezulu lensimbi ye-tungsten lukhuni kakhulu futhi liqinile. Ngakho-ke, idayimane elingagaywa liwukugaya okuqhubekayo kwendawo ebonakalayo ngamasondo amabili ebhulashi ledayimane. Le nqubo ikhiqiza inani elikhulu lokushisa futhi idinga ukwelashwa okungaphezulu okuqhubekayo kwesipholile. Ngemuva kokuqedwa, kungumkhiqizo oqediwe wezinto zensimbi ye-tungsten. Ukukhiqizwa kwezinto zenduku kungase kubonakale kulula, kodwa empeleni, kunokuqukethwe okuphezulu kwezobuchwepheshe kusukela ekulungiseleleni kokuqala kwe-tungsten powder ekubunjweni kwezinhlamvu ezisezingeni eliphezulu ngokusebenzisa i-sintering elawulwayo.

  Ngalesi sikhathi, izisebenzi zizohlola izinsimbi zensimbi ze-tungsten ukuze zibone ukuthi awekho yini amakhona alahlekile noma umonakalo, futhi uma kukhona ukuchezuka ngobude noma amabala ngaphambi kokupakisha nokuzithengisa. Ukuminyana kwensimbi ye-tungsten kuphakeme kakhulu, futhi ibhokisi elinjengaleli linesisindo somuntu omdala. Ingalayishwa elolini futhi ithuthelwe endaweni yokucubungula amathuluzi ukuze kuqhutshekwe nokucubungula izinsimbi zensimbi ze-tungsten zibe izisiki zokugaya.

  Lapho imboni yamathuluzi ithola impahla yensimbi yensimbi ye-tungsten, ithatha i-Zhuzhou Watt yami njengesibonelo, isinyathelo sokuqala ukuveza insimbi ye-tungsten futhi uhlole noma yimiphi imikhiqizo enesici. Yonke imikhiqizo enesici izoqedwa futhi ibuyiselwe kumkhiqizi. Kunezinhlobo eziningi ze-tungsten steel milling cutters, ezihambisana nezimo ezihlukene zokucubungula, ngakho-ke imboni yamathuluzi nayo inesibopho sokucwaninga nokuthuthukiswa kwamathuluzi.

  Ngokusekelwe ezimeni zokucubungula nezinto ezinikezwa yikhasimende, unjiniyela uzoklama umumo wethuluzi ohambisanayo ukuze ahlangabezane nezidingo zekhasimende. Ukuze kube lula ukucindezelwa komsiki wokugaya, sizokhipha umsila wento, futhi kungabonakala ngokucacile ukuthi umsila we-chamfered uveza umumo we-trapezoidal. Isiphathi samathuluzi ibhuloho elixhuma ithuluzi lomshini we-CNC, elingafakwa kalula kumphathi wamathuluzi. Ngemuva kwe-chamfering, sizosika futhi sifake izinto zebha, okubizwa ngokuthi umehluko wezinga kuphela ekuqondeni okuqondile kwezindiza eziphakeme neziphansi.

  Lapha, uhlaka oluqinile lwento yebha lusetshenziswa ngomshini kusetshenziswa indlela efana nokujika, futhi inqubo yokusika idinga ukupholisa okuqhubekayo ngokupholisa.

  Ukusika kuyinqubo eyinhloko ekukhiqizeni ama-milling cutters, futhi umshini wokusika uwumshini wokugaya, okuyimishini eyinhloko emafektri okucubungula amathuluzi. Igrinder ye-CNC ye-axis emihlanu engenisiwe ibiza kakhulu, ngokuvamile ibiza izigidi ngomshini ngamunye. Inani labagayi linquma ukuphuma kwamathuluzi okusika, futhi ukusebenza kwabagayi nakho kuthinta ikhwalithi yamathuluzi okusika.

  Isibonelo, uma ukuqina kwe-grinder kunamandla, ukudlidliza ngesikhathi sokucubungula kuncane, futhi i-milling cutter ekhiqizwayo inokunemba okuphezulu, ngakho ukunemba kubaluleke kakhulu kumshini wokugaya. Imishini yokugaya inemisebenzi eminingi, engathuthukisa kakhulu ukusebenza kahle komsebenzi. Zinohlu oluphelele lwamathuluzi okwenza imishini, zingalungisa ngokuzenzakalelayo ukucindezela komzila wekhebula, zilayishe futhi zilayishe izinto zokwakha, futhi zinike amandla umuntu oyedwa ukuthi agade amathuluzi emishini eminingi, ngisho nangaphandle kokugadwa.

  Ngesikhathi sokusetshenziswa, isinyathelo sokuqala ukuhlola ukugxuma kwenduku. Ngemva kokuphumelela ukuhlolwa kwe-jumping, isondo lebhulashi lisetshenziselwa ukugaya i-groove yokukhipha, umkhawulo wokusika, kanye nezingxenye ezihlukahlukene ze-milling cutter cutter emzimbeni wenduku, konke okucutshungulwa yi-grinder. Ngokufanayo, amasondo okugaya idayimane nawo asetshenziswa, ahambisana nenani elikhulu lokusika okupholisayo. I-tungsten steel milling cutter enobubanzi obungamamilimitha ama-4 ngokuvamile ithatha imizuzu emi-5-6 ukuqeda. Kodwa lokhu futhi kunqunywa umshini wokugaya. Eminye imishini yokugaya inezimbazo eziningi nokusebenza kahle okuphezulu, futhi ingacubungula abasiki bensimbi abaningi be-tungsten ngesikhathi esisodwa. Kungabonakala ukuthi ngemva kokucutshungulwa, induku yensimbi ye-tungsten ishintshile yaba i-milling cutter, futhi i-milling cutter isengumkhiqizo ophelile. Ngokomyalelo wekhasimende, amathuluzi okusika ane-palletized futhi athunyelwa ekamelweni lokuhlanza nge-ultrasonic. Ngemuva kokusika, amathuluzi okusika aqale ahlanzwe ukuze asuse uketshezi olunqunyiwe kanye nezinsalela zamafutha ku-blade ukuze kudlule kalula.

  Uma ingahlanzwa, izoba nomthelela ezinqubweni ezilandelayo. Okulandelayo, sidinga ukwenza ukwelashwa kwe-passivation kuso. I-passivation, ngokwezwi nezwi ehunyushwa ngokuthi i-passivation, ihlose ukususa ama-burrs onqenqemeni lokusika. Ama-Burrs onqenqemeni angabangela ukuguga kwamathuluzi futhi abe mahhadlahhaza ebusweni bomsebenzi ocutshunguliwe. I-sandblasting passivation efana nalokhu kusebenzisa umoya ocindezelwe njengamandla kanye nezinto zejethi ezinesivinini esikhulu ukufafaza phezu kwethuluzi. Ngemuva kokwelashwa kwe-passivation, unqenqema lokusika luba bushelelezi kakhulu, lunciphisa kakhulu ubungozi bokuqhekeka. Ubushelelezi obuphezulu be-workpiece buzophinde buthuthukiswe, ikakhulukazi kumathuluzi ahlanganisiwe, okumele abhekane nokwelashwa kwe-passivation onqenqemeni lokusika ngaphambi kokumboza ukwenza ukunamathela kunamathele ngokuqinile endaweni yamathuluzi. 

  Ngemuva kwe-passivation, nayo idinga ukuhlanzwa futhi, Ngalesi sikhathi, inhloso ukuhlanza izinhlayiya ezisele emzimbeni wethuluzi. Ngemva kwale nqubo ephindaphindiwe, ukuthambisa, ukuqina, nokuphila kwesevisi yethuluzi kuye kwathuthukiswa. Ezinye izimboni zamathuluzi azinayo le nqubo. Okulandelayo, ithuluzi lizothunyelwa embotsheni. Ukwemboza nakho kuyisixhumanisi esibaluleke kakhulu. Okokuqala, faka ithuluzi ku-pendant futhi uveze unqenqema oluzogcotshwa. Sisebenzisa i-PVD yokubeka umhwamuko obonakalayo, ehwashisa izinto ezimboziwe ngezindlela ezibonakalayo, bese iwafaka endaweni yamathuluzi. Ngokuqondile, qala ngokucofa, ubhake futhi ushise isisiki sokugaya sibe ezingeni lokushisa elidingekayo, qhumisa i-voltage engu-200V ukuya ku-1000V ngama-ion, bese ushiya umshini une-voltage ephezulu engalungile imizuzu emihlanu kuya kwengama-30. Bese ulungisa okwamanje ukuze wenze okokucwenga kuhlangane ukuze inani elikhulu lama-athomu nama-molecule angahwamuka futhi ashiye okokusebenza okuwuketshezi noma okuqinile okucwebezelayo noma kufakwe ngaphansi bese ekugcineni kufakwe endaweni yomzimba. Lungisa ukuhwamuka kwamanje njengoba kudingekile kuze kube sekupheleni kwesikhathi sokubeka, linda ukupholisa bese uphuma esithandweni. I-coating efanele ingakhuphula impilo yamathuluzi izikhathi eziningana futhi ithuthukise izinga eliphezulu le-workpiece ezocutshungulwa.

  Ngemva kokuphothulwa kokufakwa kwamathuluzi, ngokuyisisekelo zonke izinqubo eziyinhloko seziqediwe. Ngalesi sikhathi, i-tungsten steel milling cutter ingafakwa ethuluzini lomshini. Sidonsa i-milling cutter esanda kugcotshwa ekamelweni lokupakisha, futhi igumbi lokupakisha lizohlola ngokucophelela i-milling cutter futhi. Ngesibonakhulu se-anime, hlola ukuthi unqenqema lokusika luphukile yini nokuthi ukunemba kuyahlangabezana yini nezidingo, bese uyithumela ukuze umake, sebenzisa i-laser ukuze uqophe ukucaciswa kwethuluzi esibambo, bese ufaka ibhokisi le-tungsten steel milling cutter. Ukuthunyelwa kwethu komsiki wokugaya ngokuvamile kuba izinkulungwane, ngezinye izikhathi amashumi ezinkulungwane zamathani, ngakho-ke umshini wokupakisha othomathikhi awuvunyelwe Inani elincane lingasindisa izinsiza eziningi zabasebenzi kanye nezezimali. Ifekthri ehlakaniphile engenamuntu iwumkhuba wesikhathi esizayo. 

  Kubandakanya izinqubo eziningi zokuvimbela i-tungsten steel milling cutter ekukhuleni kusukela ekuqaleni, Eminyakeni yamuva, ngokuthuthuka okusheshayo kwemboni yamathuluzi, izinkampani eziningi zamathuluzi seziqale ucwaningo oluzimele nokuthuthukiswa kwamaphuzu ezobuchwepheshe ezingakalawulwa ngokugcwele ekhaya, ezifana njengobuchwepheshe bokunamathela kanye nemishini yokugaya eyi-axis emihlanu, futhi kancane kancane ibonise umkhuba wokushintsha izinto eziphuma kwamanye amazwe.
