Abakhiqizi kumele banciphise umthelela wabo kwezemvelo ngenkathi bethuthukisa ukusetshenziswa kwamandla ngokuhambisana nezinjongo zentuthuko ezimeme zomhlaba eziyi-17 ezibekwe yiNhlangano Yezizwe Ezihlangene (UN).Ngaphandle kokubaluleka kwe-CSR enkampanini, u-Sandvik Coromant ulinganisela ukuthi abakhiqizi bamosha phakathi kuka-10 no-30% wezinto ezibonakalayo ezinqubweni zabo zomshini, ngokusebenza kahle kwemishini okujwayelekile okungaphansi kuka-50%, okuhlanganisa ukuklama, ukuhlela kanye nezigaba zokusika.
Ngakho-ke yini abakhiqizi abangayenza?Imigomo ye-UN incoma izindlela ezimbili eziyinhloko, kucatshangelwa izici ezifana nokukhula kwenani labantu, izinsiza ezilinganiselwe kanye nomnotho oqondile.Okokuqala, sebenzisa ubuchwepheshe ukuxazulula lezi zinkinga.Imiqondo ye-Industrial 4.0 efana nezinhlelo ze-cyber-physical, idatha enkulu noma i-inthanethi Yezinto (IoT) ivamise ukushiwo njengendlela eya phambili yabakhiqizi abafuna ukunciphisa imfucuza.Kodwa-ke, lokhu akunaki iqiniso lokuthi abakhiqizi abaningi abakawasebenzisi amathuluzi emishini yesimanje ngamakhono edijithali ekusebenzeni kwawo kwensimbi.
Abakhiqizi abaningi bayakubona ukubaluleka kokukhethwa kwebanga ukuze kuthuthukiswe ukusebenza kahle kanye nokukhiqiza kokuphenduka kwensimbi, nokuthi lokhu kuthinta kanjani ukukhiqiza kanye nokuphila kwamathuluzi.Kodwa-ke, abantu abaningi bayaphuthelwa iqhinga ngokungawucabangeli wonke umqondo wethuluzi, kusukela kuma-blade athuthukile nezibambo kuya ezixazululweni zedijithali ezisebenziseka kalula.Ngayinye yalezi zici ingasiza ukwenza insimbi ibe luhlaza ngokunciphisa ukusetshenziswa kwamandla nokunciphisa ukumosha.
Abakhiqizi babhekana nezinselelo eziningi lapho bephendula insimbi.Lokhu kufaka phakathi ukuthola imiphetho eningi kusuka ku-blade eyodwa, ukukhulisa amazinga okukhishwa kwensimbi, ukunciphisa izikhathi zomjikelezo, ukukhulisa amazinga we-inventory kanye, vele, nokunciphisa udoti wezinto ezibonakalayo.Kodwa kuthiwani uma bekukhona indlela yokuxazulula zonke lezi zinkinga, kodwa ngokuvamile kuzuzwe ukusimama okukhulu?Enye indlela yokunciphisa ukusetshenziswa kwamandla ukunciphisa isivinini sokusika.Abakhiqizi bangagcina ukukhiqiza ngokukhulisa ngokulinganayo amanani okuphakela kanye nokujula kokusika.Ngokungeziwe ekongeni amandla, lokhu kwandisa impilo yamathuluzi.Ekushintshanisweni kwensimbi, u-Sandvik Coromant uthole ukwenyuka okungama-25% kwesilinganiso sempilo yamathuluzi, okuthe, kuhlangene nokusebenza okuthembekile nokubikezelwayo, okunciphise ukulahleka kwempahla kucezu lokusebenza nokufaka.
Ukukhetha uhlobo olufanele lweblade kungasiza ukufeza lo mgomo ngezinga elithile.Yingakho u-Sandvik Coromant engeze ipheya entsha yamabanga e-carbide ye-P-turning ebizwa ngokuthi i-GC4415 ne-GC4425 ebangeni layo.I-GC4425 inikeza ukumelana nokugqokwa okuthuthukisiwe, ukumelana nokushisa kanye nokuqina, kuyilapho ibanga le-GC4415 liklanyelwe ukuhambisana ne-GC4425 lapho ukusebenza okuthuthukisiwe kanye nokumelana nezinga lokushisa okuphezulu kuyadingeka.Kubalulekile ukuqaphela ukuthi womabili amabanga angasetshenziswa ezintweni eziqinile ezifana ne-Inconel ne-ISO-P yensimbi engagqwali engahlanganisiwe, enzima kakhulu futhi imelana nengcindezi yemishini.Ibanga elifanele lisiza umshini izingxenye eziningi ngevolumu ephezulu kanye/noma ukukhiqizwa ngobuningi.
Ibanga GC4425 lihlinzeka ngezinga eliphezulu lokuphepha kwenqubo ngenxa yekhono layo lokugcina umugqa wonqenqema unjalo.Ngenxa yokuthi okokufaka kungakwazi umshini izingxenye eziningi emphethweni ngamunye, i-carbide encane isetshenziselwa umshini inombolo efanayo yezingxenye.Ngaphezu kwalokho, okufakwayo okunokusebenza okungaguquki nokubikezelwa kuvimbela ukulimala kwengcezu yokusebenza ngokunciphisa udoti wempahla yokusebenza.Zombili lezi zinzuzo zinciphisa inani lemfucuza ekhiqizwayo.
Ngaphezu kwalokho, ku-GC4425 kanye ne-GC4415, i-core material kanye nokufakwa kwe-coating kuklanyelwe ukumelana okungcono kakhulu kwezinga lokushisa.Lokhu kunciphisa imiphumela yokugqoka ngokweqile, ngakho-ke impahla iyakwazi ukugcina umkhawulo wayo emazingeni okushisa aphezulu.
Kodwa-ke, abakhiqizi kufanele futhi bacabangele ukusebenzisa i-coolant kuma-blade abo.Uma usebenzisa amathuluzi ane-subcoolant ne-subcoolant, kungase kusize kweminye imisebenzi ukuvala ukunikezwa kwe-supercoolant.Umsebenzi oyinhloko woketshezi lokusika ukukhipha ama-chips, ukupholisa nokugcoba phakathi kwethuluzi nezinto zokusebenza.Uma isetshenziswe ngendlela efanele, ikhulisa ukukhiqiza, ithuthukisa ukuphepha kwenqubo, futhi ithuthukise ukukhiqiza kwamathuluzi nengxenye yekhwalithi.Ukusebenzisa isimeli esinesipholisi sangaphakathi nakho kwandisa impilo yamathuluzi.
Kokubili i-GC4425 ne-GC4415 zifaka ungqimba lwesizukulwane sesibili se-Inveio®, i-CVD alumina (Al2O3) eyenziwe ngomumo eyenzelwe ukucutshungulwa.Ukuhlolwa kwe-Inveio ezingeni le-microscopic kukhombisa ukuthi ingaphezulu lezinto ezibonakalayo libonakala ngokuma kwekristalu okungaqondile.Ngaphezu kwalokho, i-die orientation yesizukulwane sesibili se-Inveio coating ithuthukiswe kakhulu.Okubaluleke kakhulu kunangaphambili, i-crystal ngayinye embotsheni ye-alumina iqondaniswe ngendlela efanayo, idala umgoqo oqinile endaweni enqunyiwe.
I-Inveio inikezela ngezinto ezifakwayo ezinokumelana nokugqokwa okuphezulu nempilo yamathuluzi enwetshiwe.Ukuphila kwamathuluzi okude, yiqiniso, kunenzuzo ekwehliseni izindleko zeyunithi.Ngaphezu kwalokho, i-matrix ye-carbide enosimende iqukethe amaphesenti aphezulu e-carbide egaywe kabusha, okuyenza ibe ngelinye lamabanga ahambisana kakhulu nemvelo.Ukuhlola lezi zimangalo, amakhasimende akwa-Sandvik Coromant enze izivivinyo zangaphambi kokudayiswa ku-GC4425.Inkampani eyodwa ye-General Engineering yasebenzisa kokubili i-blade yesimbangi kanye ne-GC4425 ukuze yenze ama-press rolls.I-axial machining yangaphandle eqhubekayo kanye nokuqeda kancane kwesigaba se-ISO-P ngesivinini sokusika (vc) esingu-200 m/min, izinga lokuphakelayo elingu-0.4 mm/rev (fn) nokujula (ap) okungu-4 mm.
Abakhiqizi bavamise ukukala impilo yamathuluzi ngenani lezingxenye ezenziwe ngomshini (izingcezu).Ibanga lomuntu oqhudelana naye lifake izingxenye ezingu-12 zokugqoka ngenxa yokuguqulwa kwepulasitiki, kuyilapho i-Sandvik Coromant ifake izingxenye ezingu-18 futhi yenza kanjalo ngo-50% isikhathi eside, ngokuguga okungaguquki nokubikezelwa.Lolu cwaningo lwesibonelo lubonisa izinzuzo ezingazuzwa ngokuhlanganisa izakhi zemishini ezifanele kanye nokuthi izincomo kumathuluzi akhethwayo kanye nokusika idatha evela kozakwethu othembekile njengo-Sandvik Coromant kungaba negalelo ekucubunguleni ukuphepha futhi kunciphise imizamo yokuthola amathuluzi.Isikhathi esilahlekile.Amathuluzi aku-inthanethi afana ne-CoroPlus® Tool Guide nawo abonakale edumile, esiza abakhiqizi ukuthi bahlole ukuguqulwa kwamagama namamaki afaneleka kangcono izimfuneko zabo.
Ukusiza ekuziqapheleni inqubo ngokwayo, i-Sandvik Coromant iphinde yasungula isofthiwe yokulawula inqubo ye-CoroPlus® eqapha ukucutshungulwa ngesikhathi sangempela futhi ethatha isinyathelo ngokuvumelana nezimiso ezihleliwe lapho kuvela izinkinga ezithile, njengokumisa umshini noma ukufaka izinsimbi ezigugile.Lokhu kusiletha esincomweni sesibili se-UN mayelana nezisetshenziswa ezizinzile: ukuya emnothweni oyindilinga, ukuphatha imfucuza njengento eluhlaza, nokungena kabusha emijikelezweni yokungathathi hlangothi kwezinsiza.Kuya ngokuya kucaca ukuthi umnotho oyindilinga awuhambisani nemvelo futhi unenzuzo kubakhiqizi.
Lokhu kuhlanganisa ukugaywa kabusha kwamathuluzi e-carbide aqinile - ekugcineni, sonke siyazuza uma amathuluzi agugile engagcini esezimpondweni nasezindaweni zokulahla imfucuza.Kokubili i-GC4415 ne-GC4425 iqukethe amanani abalulekile ama-carbides atholiwe.Ukukhiqizwa kwamathuluzi amasha avela ku-carbide egaywe kabusha kudinga amandla angaphansi kuka-70% kunokukhiqizwa kwamathuluzi amasha avela ezintweni ezisantombi nto, okuphinde kuphumele ekuncipheni ngo-40% kokukhishwa kwe-CO2.Ngaphezu kwalokho, uhlelo lukaSandvik Coromant lokugaywa kabusha kwe-carbide luyatholakala kuwo wonke amakhasimende ethu emhlabeni jikelele.Izinkampani zithenga ama-blade asetshenzisiwe nemibese eyindilinga kumakhasimende, kungakhathaliseki ukuthi imvelaphi yawo.Lokhu kuyadingeka ngempela uma kubhekwa ukuthi izinto zokusetshenziswa zizoba yindlala futhi zilinganiselwe kanjani ngokuhamba kwesikhathi.Ngokwesibonelo, izinqolobane ezilinganiselwe ze-tungsten zingamathani ayizigidi ezingu-7, okuzosigcina iminyaka eyi-100.Uhlelo lokubuyisela emuva luvumele u-Sandvik Coromant ukuthi asebenzise kabusha amaphesenti angama-80 emikhiqizo yawo ngohlelo lokuthenga kabusha i-carbide.
Ngaphandle kokungaqiniseki kwemakethe yamanje, abakhiqizi abakwazi ukukhohlwa ezinye izibopho zabo, kuhlanganise ne-CSR.Ngenhlanhla, ngokwamukela izindlela ezintsha zokwenza imishini kanye nokufakwa kwe-carbide okulungile, abakhiqizi bangathuthukisa ukusimama ngaphandle kokudela ukuphepha kwenqubo futhi babhekane ngokuphumelelayo nezinselelo ezilethwe yi-COVID-19 emakethe.
U-Rolf uyiMenenja Yomkhiqizo kwa-Sandvik Coromant.Unolwazi oluningi ekuthuthukisweni komkhiqizo kanye nokuphathwa kokukhiqizwa kwezinto zamathuluzi.Uhola amaphrojekthi wokuthuthukisa ama-alloys amasha ezinhlobo ezahlukahlukene zamaklayenti njenge-aerospace, ubunjiniyela bezimoto kanye nobunjiniyela obujwayelekile.
