   Kukho uhlobo lwesixhobo sokusika esinamandla kakhulu, nokuba sisithwala emanzini okanye ijethi yokulwa esibhakabhakeni, okanye iWebb Space Telescope esandula kusungulwa exabisa i-10 yeebhiliyoni zeerandi, zonke kufuneka ziqwalaselwe yiyo. Yintsimbi yokusila i-tungsten. Insimbi ye-Tungsten inzima kakhulu kwaye luhlobo olunzima lwentsimbi eveliswa yi-manual mass production. Iyakwazi ukucubungula phantse zonke iintsimbi ngaphandle kwekhabhoni. Intsimbi engeyiyo, ekwabizwa ngokuba yi-hard alloy, ikakhulu yenziwe zii-carbides kunye ne-cobalt sintered. I-tungsten carbide powder inyibilikiswa kwi-tungsten ore. I-China lelona lizwe linemigodi ye-tungsten likhulu ehlabathini, lithatha i-58% yogcino lwe-tungsten oluqinisekisiweyo.

    Indlela yokuvelisa i-tungsten steel milling cutters? Namhlanje, itekhnoloji ye-powder metallurgy isetyenziswa ngokuqhelekileyo. Okokuqala, i-ore ye-tungsten yenziwa ibe ngumgubo we-tungsten, kwaye umgubo ucinezelwe kwi-mold eyilwe ngumatshini. Umatshini wokusila onobunzima obumalunga neetoni ezili-1000 usetyenziselwa ukucinezela. I-tungsten powder idla ngokuyilwa yindlela yokubumba elinganayo yokuntywiliselwa. Ukungqubuzana phakathi komgubo kunye nodonga lokubumba luncinci, kwaye i-billet ixhomekeke kumandla afanayo kunye nokusabalalisa kobuninzi. Ukusebenza kwemveliso kuphuculwe kakhulu.

  I-tungsten steel milling cutter yi-cylindrical, ngoko ke intsimbi ye-tungsten ecinezelweyo yi-cylinder. Ngeli xesha, intsimbi ye-tungsten yibhloko nje engumgubo edityaniswe kunye neplastikhi, kwaye ke kufuneka itshiswe.

  Esi sisithando somlilo esikhulu esihlawulisa i-tungsten powder rods kwaye izityhalele kunye ukuze zifudumale ukuya kwindawo yokunyibilika yamacandelo aphambili, ukuguqula i-aggregates yamasuntswana omgubo ekuqhekekeni kweenkozo.

  Ukucacisa ngakumbi, okokuqala, emva kokudubula okuphantsi kobushushu obuphantsi, i-ejenti yokubumba iyasuswa kwaye i-crystallization igxothwe kwiqondo lokushisa eliphakathi ukugqiba inkqubo ye-sintering kwiqondo lokushisa eliphezulu. Ubuninzi bomzimba we-sintered buyanda, kwaye ngexesha lokupholisa, amandla aqokelelwa ukufumana izinto ezifunekayo zomzimba kunye nomatshini wezinto eziphathekayo. I-Sintering yeyona nkqubo ibalulekileyo kwi-powder metallurgy.

Susa i-alloy yensimbi ye-tungsten epholileyo kwiqondo lokushisa lokushisa kwaye uqhubekele kwinqanaba elilandelayo lokugaya okungenaziko. Ukugaya okungenantliziyo yinkqubo yokupolisha, apho umphezulu wensimbi ye-tungsten unzima kakhulu kwaye unzima. Ke ngoko, idayimani enokucolwa kukusila ngokuqhubekayo komphezulu wezinto eziphathekayo ngamavili amabini ebrashi yedayimani. Le nkqubo ivelisa umthamo omkhulu wobushushu kwaye ifuna unyango oluqhubekayo lomphezulu wesipholisi. Emva kokugqitywa, yimveliso egqityiweyo yentonga yensimbi ye-tungsten. Ukuveliswa kwezinto zentonga kunokubonakala kulula, kodwa ngokwenene, kunomxholo ophezulu wezobugcisa ukusuka ekulungiseleleni kokuqala kwe-tungsten powder ukuya ekubunjweni kweenkozo eziphezulu eziphezulu ngokusebenzisa i-sintering elawulwayo.

  Ngeli xesha, abasebenzi baya kuhlola imivalo yensimbi ye-tungsten ukuze babone ukuba kukho naziphi na iikona ezilahlekileyo okanye umonakalo, kwaye ukuba kukho ukuphambuka ubude okanye amabala ngaphambi kokupakishwa nokuzithengisa. Ubuninzi bentsimbi ye-tungsten buphezulu kakhulu, kwaye ibhokisi enjengale inobunzima bomntu omdala. Inokulayishwa kwilori kwaye ithuthelwe kwisixhobo sokulungisa isixhobo ukuze iqhubekisele phambili inkqubo yeentsimbi ze-tungsten zibe ngabasiki bokungqusha.

  Xa i-factory yesixhobo ifumana i-tungsten intonga yensimbi, ithatha i-Zhuzhou Watt yam njengomzekelo, isinyathelo sokuqala kukuveza intsimbi ye-tungsten kwaye ukhangele nayiphi na imveliso ephosakeleyo. Zonke iimveliso ezineziphene ziya kupheliswa kwaye zibuyiselwe kumenzi. Kukho iintlobo ezininzi ze-tungsten steel milling cutters, ezihambelana neendawo ezahlukeneyo zokucwangcisa, ngoko ke i-factory yesixhobo nayo inoxanduva lophando lwesixhobo kunye nophuhliso.

  Ngokusekelwe kwiimeko zokucwangcisa kunye nezinto ezibonelelwa ngumthengi, injineli iya kuyila imo yesixhobo esihambelanayo ukuhlangabezana neemfuno zomthengi. Ukuze kube lula ukubamba i-cutter yokugaya, siya kugubungela umsila wezinto eziphathekayo, kwaye kunokubonwa ngokucacileyo ukuba umsila we-chamfered ubonisa i-trapezoidal shape. Umnini wesixhobo yibhuloho edibanisa isixhobo somatshini we-CNC, esinokufakwa lula kumphathi wesixhobo. Emva kwe-chamfering, siya kunqumla kwaye sifake izinto zebar, ezibizwa ngokuba ngumahluko wenqanaba kuphela kwicala elithe nkqo leenqwelomoya eziphakamileyo neziphantsi.

  Apha, ulwandlalo olurhabaxa lwezinto zebar lutshintshwa kusetyenziswa indlela efana nokujika, kwaye inkqubo yokusika ifuna ukupholisa okuqhubekayo kunye ne-coolant.

  Ukusika umgca yinkqubo ephambili kwimveliso ye-milling cutters, kwaye umatshini wokusika umatshini wokugaya, eyona zixhobo eziphambili kwiifektri zokucubungula izixhobo. Igrinder ye-CNC evela kumazwe angaphandle ibiza kakhulu, idla ngokuxabisa izigidi kumatshini ngamnye. Inani labagayi limisela imveliso yezixhobo zokusika, kwaye ukusebenza kwegrinder kuchaphazela umgangatho wezixhobo zokusika.

  Ngokomzekelo, ukuba ukuqina kwe-grinder kunamandla, ukungcangcazela ngexesha lokucubungula kuncinci, kwaye i-milling cutter eveliswayo inokuchaneka okuphezulu, ngoko ke ukuchaneka kubaluleke kakhulu kwi-grinder. Oomatshini bokugaya banemisebenzi emininzi, enokuphucula kakhulu ukusebenza kakuhle. Banoluhlu olupheleleyo lwezixhobo zoomatshini, banokuhlengahlengisa ngokuzenzekelayo uxinzelelo lwe-cableway, ukulayisha kunye nokukhulula izinto eziphathekayo, kwaye kwenza ukuba umntu omnye alawule izixhobo ezininzi zoomatshini, nangaphandle kokubeka iliso.

  Ngexesha lokusetyenziswa, inyathelo lokuqala kukujonga ukutsiba kwentonga. Emva kokuphumelela uvavanyo lokutsiba, ivili lebrashi lisetyenziselwa ukugaya i-groove yokukhupha, ukusika, kunye neendawo ezahlukeneyo ze-milling cutter cutting edge kumzimba wentonga, zonke zicutshungulwa yi-grinder. Ngokufanayo, amavili okugaya idayimani nawo asetyenziswa, ehamba kunye nesixa esikhulu sokusika i-coolant. I-tungsten steel milling cutter enobubanzi beemilimitha ezi-4 ngokuqhelekileyo ithatha imizuzu emi-5-6 ukugqiba. Kodwa oku kukwamiselwa ngumatshini wokugaya. Abanye oomatshini bokusila baneezembe ezininzi kunye nokusebenza okuphezulu, kwaye banokucutha ii-tungsten ezininzi zokusika intsimbi ngaxeshanye. Ingabonwa ukuba emva kokucutshungulwa, intonga yensimbi ye-tungsten iguqule i-milling cutter, kwaye i-milling cutter iseyimveliso egqityiweyo. Ngokomyalelo womthengi, izixhobo zokusika zifakwe kwi-palletized kwaye zithunyelwa kwigumbi lokucoca i-ultrasonic. Emva kokusika, izixhobo zokusika zihlanjululwa kuqala ukuze zisuse i-cutting fluid kunye ne-oyile eseleyo kwi-blade ukuze kube lula ukuhamba.

  Ukuba ayicocwanga, iya kuba nefuthe kwiinkqubo ezilandelayo. Okulandelayo, kufuneka senze unyango lwe-passivation kuyo. I-Passivation, iguqulelwe ngokoqobo njenge-passivation, ijolise ukususa i-burrs kwi-cut cut edge. IiBurrs kumphetho wokusika zinokubangela ukunxitywa kwesixhobo kunye nokurhabaxa komphezulu womsebenzi owenziweyo. I-Sandblasting passivation efana nale isebenzisa umoya oxinanisiweyo njengamandla kunye nezixhobo zejethi ezinesantya esiphezulu ukutshiza kumphezulu wesixhobo. Emva kokunyangwa kwe-passivation, umda wokusika uba lula kakhulu, unciphisa kakhulu umngcipheko wokutshiza. Umphezulu ogudileyo we-workpiece uya kuphuculwa, ngakumbi izixhobo ezigqunywe, ekufuneka zingene kunyango lwe-passivation kumphetho wokusika ngaphambi kokugquma ukwenza i-coating incamathele ngakumbi kwindawo yesixhobo. 

  Emva kokudlula, kufuneka kwakhona ihlanjululwe kwakhona, Ngeli xesha, injongo kukucoca amaqhekeza ashiyekileyo kumzimba wesixhobo. Emva kwale nkqubo iphindaphindiweyo, ukuthambisa, ukuqina, kunye nobomi benkonzo yesixhobo buphuculwe. Ezinye iifektri zezixhobo azinayo le nkqubo. Emva koko, isixhobo siya kuthunyelwa kwisambatho. Ukwaleka kwakhona ikhonkco ebaluleke kakhulu. Okokuqala, faka isixhobo kwi-pendant kwaye uveze umphetho oza kugqunywa. Sisebenzisa i-PVD yokubeka umphunga womzimba, eyenza izinto ezigqunyiweyo zibe ngumphunga ngeendlela eziphathekayo, kwaye emva koko sizibeke kwindawo yesixhobo. Ngokukodwa, qala ucofe, ubhake kwaye ufudumeze isisiki sokusila ukuya kubushushu obufunekayo, bhobhoza amandla ombane angama-200V ukuya kwi-1000V ngee-ion, kwaye ushiye umatshini unevoltheji ephezulu engalunganga kangangemizuzu emihlanu ukuya kwengama-30. Emva koko ulungelelanise langoku ukwenza izinto zokucwenga zibe fusible ukuze inani elikhulu le-athomu kunye neeathom zibenomoya kwaye zishiye izinto zolwelo zokucoca okanye umphezulu wezinto eziqinileyo okanye i-sublimated kwaye ekugqibeleni ifakwe kumphezulu womzimba. Lungisa i-evaporation yangoku njengoko kufuneka kude kube sekupheleni kwexesha lokubeka, linda ukupholisa uze uphume kwisithando somlilo. Ukugquma okufanelekileyo kunokunyusa ubomi besixhobo ngamaxesha amaninzi kwaye kuphuculwe umgangatho womsebenzi oza kucutshungulwa.

  Emva kokuba i-coating yesixhobo igqityiwe, ngokusisiseko zonke iinkqubo eziphambili zigqityiwe. Ngeli xesha, i-tungsten steel milling cutter inokufakwa kwisixhobo somatshini.
