Nokho, izinsimbi ze-austenitic zaziwa kakhulu ngokuqina ngesikhathi kucutshungulwa, okusho ukuthi ithuluzi lokusika kumele lihlangane nezinto ngamandla angaguquki ukuze ligweme ukonakala kwendawo nokuguga kwethuluzi ngaphambi kwesikhathi. Abakhiqizi abasebenza ngobuchuleukucutshungulwa kwe-CNC okunembayose bathuthukise izinhlanganisela ezithile zezinga lokudla (feed rate) nesivinini ukuze kulwisane nalokhu kuthambekela kuyilapho kugcinwa ukunemba kobukhulu. Ukukhetha kwe-chip breaker geometry efanele nakho kubalulekile, ngoba ama-chips amade, anemicu angazibhijela ithuluzi futhi abangele ukwakheka kokushisa okulimaza kokubili ucezu lomsebenzi kanye nokugunda. Ngendlela efanele, insimbi ye-austenitic stainless steel ikhiqiza izingxenye eziqinile, ezicocekile, nezibukeka kahle, okwenza zibe ukukhetha kokuqala kwemishini yokucubungula ukudla, imishini yemithi, kanye nezinsimbi zokwakha.

Izinsimbi ze-stainless ze-Ferritic ziqukethe i-chromium kodwa i-nickel encane noma ingekho, okwenza zibe namandla kazibuthe futhi ngokuvamile zibe shibhile kunezigaba ze-austenitic ngenkathi zisalokhu zinikeza ukumelana nokugqwala okuhle ezindaweni ezinobumnene. Lezi zinto kulula ukuzisebenzisa ngemishini kunezinsimbi ze-austenitic ngoba azisebenzi kanzima ngendlela enolaka, nakuba zingathambekela ekwakhekeni kwama-burr emaphethelweni uma imingcele yokusika ingalungiswanga kahle. Izigaba ze-Martensitic, ngokuphambene, ziyakwazi ukuqina ngokwelashwa ngokushisa futhi zivame ukusetshenziselwa izingxenye ezidinga amandla aphezulu nokumelana nokugqokwa, njengezinti zamaphampu, ama-turbine blade, nezinsimbi zokuhlinza. Ukusebenza ngemishini kwe-martensitic stainless steel kufanele kwenziwe esimweni se-annealed, kulandelwe ukuqinisa nokuthambisa, ukuze kugwenywe ukuqhekeka nokuhlanekezela kobukhulu. Izinsimbi ze-Duplex stainless, eziqukethe ukwakheka okuxubile kwe-austenite ne-ferrite, zinikeza amandla e-yield acishe aphindwe kabili kunalawo ezigaba ezijwayelekile ze-austenitic ngenkathi zigcina ukumelana nokugqwala okuhle kakhulu. Ukucubungula izigaba ze-duplex kudinga amathuluzi aqinile nokumiswa kwemishini okuqinile ngoba amandla azo aphezulu akhiqiza amandla okusika abalulekile angaholela ekudlidlizeni nasekupheleni kobuso obubi uma engaphathwa kahle. Ngayinye yalezi zinhlobo zezinto idlala indima ethile ekukhiqizeni kwezimboni, futhi abahlinzeki bezinsizakalo abanokuhlangenwe nakho abanjengoI-Windason Technology qonda ukuthi ungayifanisa kanjani insimbi efanele nezidingo zokusebenza.

Ukusebenza kwemishini yokulawula ngekhompyutha (CNC) kuguqule indlela izingxenye zensimbi engagqwali (stainless steel) ezikhiqizwa ngayo, kuletha amazinga angakaze abonwe obuchule, ukuphindaphindeka, nokusebenza kahle endaweni yokukhiqiza. Ukuqina kwemishini yesimanje ye-CNC machining centers kuvumela abakhiqizi ukuthi bathathe ukusika okunamandla ensimbi engagqwali ngenkathi begcina amazinga aqinile okulinganisa obekungeke kwenzeke ngemishini yezandla esizukulwaneni esisodwa esedlule. Imishini enama-axis amaningi ingenza ukugaya (milling), ukubhoboza (drilling), ukuphendula (turning), nokugoqa (tapping) endaweni eyodwa, inciphisa izikhathi zomjikelezo futhi iqede amaphutha ezikhundleni aqongelelana lapho ucezu lomsebenzi luhanjiswa phakathi kwemishini ehlukene. Leli khono libaluleke kakhulu ezakhiweni eziyinkimbinkimbi ezifana nezihlanganisi ezinemicu (threaded fittings), imizimba yamavalvu (valve bodies), nezingxenye zezokwelapha ezifakelwayo ezidinga ubudlelwano obunembile bama-engeli nokushintsha okubushelelezi phakathi kwezindawo. Iqhaza le-CNC enkathini yezimboni alinakulinganiswa, ngoba linike amandla ukwenziwa ngendlela eningi (mass customization) nezindlela zokukhiqiza zokulungisa ngesikhathi (just-in-time) ezigcina izindleko zempahla ziphansi ngenkathi ziphendula ngokushesha ezidingweni ezishintshayo zamakhasimende. Ekuqhubekeni kwezingxenye zensimbi engagqwali, inhlanganisela yezilawuli zemishini ezithuthukile nesofthiwe ye-CAM enobuhlakani ivumela abahleli ukuthi balingise izindlela zamathuluzi, babikezele amandla okusika, futhi balungise imingcele ngaphambi kokuba ucezu olulodwa lusikwe, kususwa ngokuphumelelayo izindlela ezibizayo zokuzama nokwenza iphutha. Ngenxa yalokho, abakhiqizi bangaletha imiphumela yekhwalithi ephezulu yokucubungula insimbi engagqwali ehlangabezana nezimfuno eziqinile ze-aerospace, ezokwelapha, nezimoto ngokuthembeka okungaguquki kwenqubo.

Naphezu kwamandla emishini yesimanje ye-CNC, ukucutshungulwa kwensimbi engagqwali kuza nezinselele eziningi eziqhubekayo ezidinga izixazululo eziqaphile zobunjiniyela. Ubunzima obuyinhloko ukuphathwa kokushisa, ngoba insimbi engagqwali inokushisa okuphansi uma iqhathaniswa nensimbi yekhabhoni, okwenza ukushisa kugxile endaweni yokusika kunokuba kusabalale nge-chip. Lokhu kushisa okugxilile kusheshisa ukugqoka kwethuluzi, kukhuthaze ukwakheka kwe-built-up edge, futhi kungadala ukunwebeka ngenxa yokushisa okulimaza ukunemba kobukhulu. Ukulwa nalokhu, abakhiqizi basebenzisa izinhlelo zokumanzisa ezinomfutho ophezulu eziletha uketshezi ngqo endaweni yokusika, zikhiphe ukushisa nama-chips ngenkathi zithambisa unqenqema lokusika. Enye inkinga evamile ukuqina ngenxa yokusebenza (work hardening), ikakhulukazi ezinhlotsheni ze-austenitic, lapho ungqimba olungaphezulu luba lukhuni futhi lube namandla okugqoka njengoba liguqulwa ithuluzi lokusika. Abahleli bohlelo balwa nalokhu ngokugcina ubuncane bobukhulu be-chip futhi bagweme ama-dwell marks noma ukudlula okulula kokuphela okuhlikihla kunokuba kusike. Ukudlidliza (vibration) nokukhala (chatter) kuyinselele yesithathu, ikakhulukazi lapho kucutshungulwa izingxenye ezinodonga oluncane noma imigodi ejulile, okudinga ukusetshenziswa kwezibambi zamathuluzi ezilinganiselayo, ama-end mill anama-pitch aguquguqukayo, kanye namasu okucutshungula aguquguqukayo alungisa amazinga okuphakelayo ngesikhathi sangempela ngokusekelwe kumpendulo yamandla okusika. Izinkampani ezifana ne-Windason basebenzisa lezi zindlela ezithuthukisiwe ukuletha izingxenye zensimbi ezenziwe ngezifiso ezihlangabezana namazinga ekhwalithi anamandla ngenkathi kuthuthukiswa ukusebenza kahle kokukhiqiza.

Ukucutshungulwa kwe-CNC kuyingxenye ebalulekile yale nqubo ngoba kusebenzisa amathuluzi alawulwa ikhompyutha ukuze kutholakale ukunemba okuphezulu nokuphindaphindeka lapho kwakhiwa izakhiwo eziyinkimbinkimbi, izici ezinemicu, kanye nobuso obunobudedengu obuqinile okunzima noma okungenzeki ukukukhiqiza ngezindlela ezenziwa ngesandla.

Izigaba ezivame kakhulu ukwenziwa ngomshini yi-austenitic stainless steel ezifana ne-304 ne-316 ngoba zinikeza ukumelana nokugqwala okuhle kakhulu nokwenziwa ngomshini okuhle uma kusetshenziswa imingcele efanele yokusika. Nokho, igaba elingcono kakhulu lincike ezidingweni ezithile zokusetshenziswa—izigaba ze-martensitic zikhethwa ukumelana nokugqokwa, izigaba ze-duplex zamandla aphezulu, nezigaba ze-ferritic zezinhlelo ezibiza kancane ezindaweni ezinobumnene.

Izinselele ezinkulu zihlanganisa ukushisa okwengeziwe ngenxa yokushisa okuphansi, ukuqina kwendawo yezinto, nokudlidliza noma ukuxokozela ngesikhathi sokusika. Lokhu kunqotshwa ngokusebenzisa amasistimu okukhipha ukushisa anomfutho ophezulu, amathuluzi ane-positive rake geometries anezinto ezikhethekile, ukugcina ubuncane be-chip thickness ukuze kugwenywe ukuhlikihla, nokusebenzisa izinhlaka eziqinile zamashini namabhalansi amathuluzi.

Yebo, izingxenye zensimbi engagqwali zingashiselwa ngemva kokucubungula, kodwa kudingeka ukunakekela ukukhetha i-filler metal efanele nokulawula ukushisa ukuze kugwenywe i-sensitization nokuncipha kwe-carbide endaweni ethintekile. Ngemva kokushisela, kuvame ukudingeka ukuthi kwenziwe i-passivation noma i-pickling ukuze kubuyiselwe ukumelana nokugqwala, futhi izindawo ezicubunguliwe zingadinga ukuvikelwa ekuhlanganiseni kwe-weld spatter ngesikhathi sokwenza.

Ukuqeda ubuso kusukela kokucutshungulwa nje (ngokuvamile 1.6 kuya ku-3.2 µm Ra) kuya ekupholishweni okucwengekile ngaphansi kuka-0.2 µm Ra okutholakala ngokugaya nokukhuhla okulandelanayo. I-Electropolishing nayo ivame ukusetshenziselwa ukususa ama-burr amancane angabonakali nokuthuthukisa ukumelana nokugqwala, kuyilapho i-bead blasting inikeza ukubukeka okufanayo okungacwebezelanga ezinhlelweni zobuhle.

I-Windason Technology isebenzisa imishini yokulinganisa izixhumanisi, izindlela zokuhlola ezingonakalisi, kanye nokulawula izinqubo zezibalo ukuze iqaphe ubukhulu nobuhle bomhlaba phakathi nokukhiqiza. Inkampani futhi igcina ukulandeleka kwezinto ngokuqinile futhi ilandela izindinganiso zekhwalithi eziqondene nomkhakha ezifana ne-AS9100 yezindiza kanye nemihlahlandlela ye-FDA yezingxenye zezokwelapha nokucubungula ukudla.

Izimboni zezindiza, ukukhiqiza imishini yezokwelapha, imishini yokucubungula ukudla, uwoyela negesi, izimoto, kanye nezimboni zokucubungula amakhemikhali yizona ezizuzayo kakhulu. Umkhakha ngamunye udinga izinhlobo ezithile zezinto, amazinga okubekezelela, kanye nokuphela komhlaba okutholakala kubanikezeli be-CNC abanokuhlangenwe nakho ngamathuluzi akhethekile nobuchule bezinqubo.

I-Coolant idlala indima ebalulekile ekuphathweni kokushisa, ukugcoba indawo yokusika, nokukhipha ama-chips endaweni yokusebenza. Ama-emulsion ancibilikayo emanzini anama-additive ezimo eziphithiphithi ayisincomo esivame kakhulu ngoba ahlinzeka ngokupholisa nokugcoba okusebenzayo kuyilapho ehambisana nezinto eziningi zokusika ze-carbide nezinhlelo zemishini.

Ukucubungula izingxenye zensimbi engagqwali ngokuvamile kubiza kakhulu kunokwenziwa kwe-carbon steel noma i-aluminium machining ngenxa yezindleko eziphakeme zezinto zokusebenza, ukugqoka kwamathuluzi okwandayo, kanye nesivinini esincishisiwe sokusika. Nokho, ukumelana nokugqwala okuphezulu, amandla, nokuphila isikhathi eside kwensimbi engagqwali kuvame ukuholela ezindlekweni eziphansi zomjikelezo wempilo wonke ezicelweni lapho ukuqina nokuhlanzeka kubalulekile.

Ikusasa lokwenziwa kwe-CNC ekucubunguleni insimbi engagqwali libandakanya ukusebenza ngokuzenzakalelayo okukhulu, ukuhlanganiswa kwe-AI ukuze kulungiswe inqubo ngesikhathi sangempela, kanye nezindlela ezihlanganisayo ezihlanganisa ukukhiqiza okungeziwe nokuqeda okunciphayo. Le ntuthuko izovumela ukukhiqizwa okusheshayo, ukubekezelela okuqinile, kanye nezakhiwo eziyinkimbinkimbi kakhulu ngenkathi kunciphisa imfucuza nokusetshenziswa kwamandla kuyo yonke imboni.
