Ukucutshungulwa kwensimbi engagqwali kwezimboni kuveza "udonga lokusebenza" olukhulu kakhulu kubasebenzi bensimbi abaningi kanye nochwepheshe bokuthenga. Ngenkathi insimbi engagqwali inikeza ukumelana nokugqwala okumangalisayo kanye nokukhanga kobuhle, izakhiwo zayo zemishini ezingokwemvelo zenza kube nzima kakhulu ukuyisebenzisa. Amazinga aphezulu okuqina komsebenzi kanye nokushisa okuphansi kuvame ukuholela ekugugeni okusheshayo kwamathuluzi noma ukwehluleka okukhulu lapho kusetshenziswa imishini ejwayelekile. Le nselele ivame ukuvusa impikiswano ebalulekile emakethe yamathuluzi yomhlaba wonke: Ingabe i-cobalt iyimfuneko ngempela yokubhoboza insimbi engagqwali ngempumelelo? Njengomuntu oqashelwayoUmthumeli we-China Top Metal Cobalt Drill Bit, I-Jiacheng Tools iphendula lo mbuzo ngokuhlaziya ukuhlangana kwensimbi yamathuluzi nezinto zokusebenza eziqinile. Ukuqonda ukuhambisana kwezinto akuyona nje imininingwane yobuchwepheshe; kuyimfuneko yamasu kubasabalalisi abafuna ukunikeza izixazululo ezinokwethenjelwa embonini yezindiza, yezimoto, kanye neyokucubungula ukudla.
Ukukhetha ithuluzi elifanele kudinga ukujula ngokujulile endleleni ama-alloy ahlukene aziphatha ngayo ngaphansi kokushisa okukhulu kanye nengcindezi yendawo yokusika. Lo mhlahlandlela uhlola isidingo sokusebenza kwe-cobalt ngelensi yochwepheshe, unikeza ukucaca kokuthi nini futhi kungani kudingeka ama-alloy akhethekile ukuze kulondolozwe ukusebenza kahle kokukhiqiza.
Umbuzo 1: Kungani ama-drill bits ajwayelekile e-HSS evame ukwehluleka uma ehlangana nensimbi engagqwali?
Ukuze uqonde ukuthi kungani i-standard High-Speed Steel (HSS) "ishaya" noma yehluleka ngesikhathi sokusetshenziswa kwensimbi engagqwali, umuntu kufanele ahlole i-physics yokusikwa. Insimbi engagqwali iyisiqhubi esibi sokushisa. Ngokungafani nensimbi yekhabhoni, evumela ukushisa ukuthi kuhlakazeke endaweni yokusebenza kanye nama-chips, insimbi engagqwali ibamba amandla okushisa lapho ithintana khona phakathi komphetho wethuluzi nensimbi. Lokhu kwakheka kokushisa kwendawo kungafinyelela amazinga okushisa angaphezu kwama-degree Celsius angu-600 ngemizuzwana.
Amathuluzi ajwayelekile e-HSS, ngokuvamile enziwe ngensimbi yebanga le-M2, anomkhawulo othize "wobulukhuni obubomvu". Uma izinga lokushisa selidlule lo mkhawulo, umkhawulo ophambili uyathamba, into eyaziwa ngokuthi ukuguqulwa kwepulasitiki. I-Cobalt ishintsha ngokuphelele lesi sibalo samakhemikhali. Ngokusebenza njenge-matrix yokuzinza, i-cobalt iphakamisa izinga lokushisa lapho insimbi iqala ukuthamba khona.Amathuluzi e-Jiacheng Igxile kuma-grade e-HSS M35 kanye ne-M42, lapho ukungezwa kwe-cobalt kuqinisekisa ukuthi i-drill bit igcina ubuqotho besakhiwo sayo kanye nomkhawulo obukhali ngisho noma indawo yokusika ikhanya ngokubomvu. Ngaphandle kwe-cobalt, ukungqubuzana okubangelwa uhlobo oluqinile, "oluthambile" lwensimbi engagqwali kuzothuntubeza i-bit ejwayelekile cishe ngokushesha, okuholela ezidingweni zokucindezela okukhulu kanye nokuphuka okungenzeka.
Umbuzo 2: Phakathi kuka-5% Cobalt (M35) no-8% Cobalt (M42), ochwepheshe kufanele bakhethe kanjani ngokusekelwe ezidingweni ezithile?
Ukukhethwa kwezinto ezibonakalayo akuvamile ukuthi kube "okunye kungcono ngaso sonke isikhathi." Kunalokho, kuyibhalansi phakathi kobulukhuni nokuqina. Abathumeli abangochwepheshe bahlukanisa amathuluzi e-cobalt abe ngama-grade amabili ayisisekelo ukuze bahlangabezane nezidingo zezimboni ezahlukene. I-Jiacheng Tools inikeza uhlaka lokukhetha olunembile kubalingani bayo bamazwe ngamazwe ukuqinisekisa ukuthi ithuluzi lihambisana ne-alloy ethile ebholwa.
Ngezinsimbi ezijwayelekile ze-austenitic stainless steels, njenge-Grade 304, i-HSS M35 (equkethe i-cobalt engu-5%) ngokuvamile iyisinqumo esingabizi kakhulu nesisebenza kahle. I-M35 inikeza ukwanda okukhulu kokumelana nokushisa ngaphezu kwe-M2 ngenkathi igcina ukuqina okwanele ukumelana nokudlidliza kokubhoboza ngesandla noma okuzenzakalelayo. Kodwa-ke, lapho ukusetshenziswa kuhilela izinto ezidinga kakhulu njenge-Grade 316, i-Grade 317, noma i-Super Duplex stainless steel, ukushintshela ku-HSS M42 (equkethe i-cobalt engu-8%) kuyadingeka. I-M42 ifinyelela ubunzima be-Rockwell obuphezulu (HRC), obubalulekile ekungeneni kwezinsimbi ezibonisa ukuqina okukhulu kokusebenza. Ukushintshana ukuthi i-M42 ibuthakathaka kancane kune-M35. Ngakho-ke, i-M42 ilungele izindawo ze-CNC eziqinile, ezinembe kakhulu lapho ukuzinza komshini kunciphisa khona ingozi yokuqhekeka eceleni. Leli zinga lokuhlukanisa ngobungcweti livumela abasabalalisi ukuthi banikeze izeluleko ezifanelekile kumakhasimende abo, bathuthukise kokubili impilo yamathuluzi kanye nesabelomali sephrojekthi.
Umbuzo 3: Ngale kokwakheka kwezinto, ukwakheka kwejometri kudala kanjani umphumela "wokusika okubandayo"?
Nakuba ingxubevange inikeza isisekelo, ukwakheka kwejometri kwaleli thuluzi kusebenza njengenjini yokusebenza. Amabhithi okubhoboza e-Cobalt ahloselwe ukusebenza ngensimbi okunzima avame ukuba nokuguqulwa okuhlukile okuhlukile kumabhithi enhloso ejwayelekile. Isibonelo esiyinhloko ukusetshenziswa kwephuzu lokuhlukaniswa kwamadigri ayi-135. Amabhithi ajwayelekile avame ukuba nephuzu lamadigri ayi-118, elifanele izinsimbi ezithambile kodwa elivame "ukuhamba" ebusweni obuqinile bensimbi engagqwali.
I-engeli engama-degree angu-135 inikeza iphrofayili eyisicaba ethinta indawo engaphezulu ngokushesha, okwenza ithuluzi likwazi ukuzibamba. Lo mklamo, kanye nokwakhiwa "kwewebhu ebanzi", kwandisa ukuqina kwe-drill iyonke. I-Jiacheng Tools isebenzisa futhi ukugaya okunembile okukhethekile ukuze kufezwe "indawo yokuhlukana" enciphisa ubude bomphetho we-chisel. Lokhu kuguqulwa kunciphisa kakhulu ukucindezelwa kwe-axial okudingekayo ukuze kungene izinto. Ngokunciphisa amandla adingekayo ukusika, ithuluzi lidala ukungqubuzana okuncane, futhi ngenxa yalokho, ukushisa okuncane. Lokhu kubambisana phakathi kwe-metallurgy ye-M35/M42 kanye ne-geometry ethuthukisiwe kudala lokho onjiniyela abakubiza ngokuthi umphumela "wokusika okubandayo", lapho ithuluzi lihlala lizinzile futhi umsebenzi uhlala ungalinyazwa ukucindezeleka kokushisa.
Kusukela Ekukhetheni Izinto Ezibalulekile Kuya Ekuthuthukiseni Uchungechunge Lokunikezela
Ukuxazulula "udonga lokusebenza" lwensimbi engagqwali kudinga okungaphezu nje kwethuluzi elilodwa lekhwalithi ephezulu; kudinga uhlelo lokukhiqiza oluqinisekisa ukuthi yonke inqwaba ihlangabezana nezindinganiso ezifanayo eziqinile. Kwabasabalalisi bomhlaba wonke, inselele ukuthola umlingani ongahlanganisa lobu buchwepheshe bobuchwepheshe nokuhlinzekwa okuzinzile, okukhulu.

Ubambiswano oluthembekile luvumela abasabalalisi ukuthi bagxile ekwandiseni imakethe kunokuxazulula izikhalazo zekhwalithi. I-Jiacheng inikezaizinsizakalo eziphelele ze-OEM kanye nezelebula ezizimele, okuvumela abanikazi bomkhiqizo ukuthi banikeze osayizi abakhelwe ngokwezifiso kanye nezingubo zokusebenza okuphezulu njenge-Amber noma i-TiN (Titanium Nitride) ezimakethe zabo zasendaweni. Lezi zingubo zithuthukisa kakhulu ukuthamba kanye nokumelana nokuguguleka kwesisekelo se-cobalt, zinikeza ungqimba olwengeziwe lokuvikela esimweni sokuguguleka kwensimbi engagqwali. Njengoba ineminyaka engu-15 yesipiliyoni sokuthumela ngaphandle, ifektri igcina ukuxhumana okucacile kanye nezinhlelo zokukhiqiza ezithembekile, iqinisekisa ukuthi abalingani bamazwe ngamazwe banokuhlinzekwa okuqhubekayo kwamathuluzi adingekayo kubunjiniyela besimanje bokunemba.
Ukubambisana Okuhlelekile Kokusebenza Kwemishini Okubaluleke Kakhulu
Ingabe i-cobalt iyadingeka ensimbi engagqwali? Kunoma yikuphi ukusetshenziswa lapho ukusebenza kahle, ukunemba, kanye nobude besikhathi samathuluzi kuyizinto eziza kuqala, impendulo inguyebo oqinisekile. Nakuba ama-HSS bits ajwayelekile angaphatha izimbobo ezimbalwa kumashidi amancane, awakwazi ukuncintisana nokuzinza kokushisa kanye nokugcinwa komngcele wama-alloy acebile nge-cobalt endaweni yezimboni. Ukukhetha ibanga le-cobalt elifanele kanye nokucushwa kwejiyometri kuyindlela ephumelela kakhulu yokunqoba izinselele zemishini zama-alloy aqinile.
I-Jiacheng Tools isazinikele ekuthuthukiseni ukusebenza kwe-HSS M35 kanye ne-M42 tooling. Ngokuhlanganisa isayensi yensimbi kanye nokukhiqizwa okunembile, inkampani inikeza umgogodla wezobuchwepheshe kochwepheshe bokusebenza ngensimbi emhlabeni wonke. Kwabasabalalisi kanye nezikhulu zokuthenga zezimboni, ukukhetha umlingani oqonda lokhu kuhambisana kwezinto kuyisinyathelo sokuqala sokufinyelela ubuhle bokusebenza. Njengoba isidingo somhlaba wonke sezingxenye zensimbi engagqwali siqhubeka nokukhula, indima yemishini yokubhola i-cobalt esebenza kahle kakhulu izoba yinto ebaluleke kakhulu.
