Uhlanganyele imiphumela yocwaningo olunemininingwane eqhutshwa yinkampani eqhathanisa imigoqo eqinile engu-625 ene-Sanicro 60
Ibanga lokuncintisana ibanga eli-625 (UNSU NUM N06625) liyi-superalloy esuselwa ku-nickel (Superalloy yokushisa) esetshenzisiwe kwizimboni zasolwandle, zenuzi kanye nezinye izimboni kusukela ekuthuthukisweni kwayo okuphezulu ngenxa yezakhiwo zayo eziphakeme kanye nokumelana namazinga okushisa aphezulu. amazinga okushisa. Ukwandise ukuvikelwa ngokugqwala kanye ne-oxidation.
I-Challenger New entsha iyinto ehlukahlukene ehlukile kweSanicro 60 (eyaziwa nangokuthi Alloy 625). I-Sandvik entsha ye-Hole Core yenzelwe ukuhlinzeka ukusebenza okungcono ezindaweni ezithile ezihlaselwe yi-Incontel 625, eyenziwe ngamandla aphezulu ama-nickel-chromium alloy angamelana nezindawo eziphakeme kakhulu ezinamazinga aqukethe ama-chlorine. Ukumelana nokugqwala kokuhlangana kanye nokugqwala kwengcindezelo, kunokumelana nokuphikiswa okukhohlisayo (pre) kukhulu kune-48.
Inhloso yocwaningo kwakuwukuhlola ngokuphelele futhi uqhathanise umsebenzi we-sanicro 60 (ububanzi = 72 mm) nge-inconel 625 (ububanzi = 77 mm). Izindlela zokuhlola ziyimpilo yamathuluzi, ikhwalithi engaphezulu nokulawulwa kwe-chip. Yini ezovezwa: iresiphi entsha yebha yebha noma ibha yonke ephelele?
Uhlelo lokuhlola eSandvik Coromant e-Milan, i-Italy liqukethe izingxenye ezintathu: ukuguquka, ukumba nokushaya.
I-MCM evundlile machinach maching Center (HMC) isetshenziselwa ukumba kokushaya nokushaya. Ukuguqula imisebenzi kuzokwenziwa ku-Mazak Internet Mach 2 Kusetshenziswa abanikazi be-Capto nge-coolant yangaphakathi.
I-Tool Life Ithuluzi Lahlolwa Ukuhlola Ithuluzi Ukugqokwa kwesivinini esisuka ku-60 kuye ku-125 m / min usebenzisa i-S05f Alloy grade efanelekile ekuqedeni nasekuqedisweni. Ukukala ukusebenza kokuhlolwa ngakunye, ukususwa kwezinto ezibonakalayo ngesivinini ngasinye sokusika kukalwa ngezindlela ezintathu eziphambili:
Njengesinye isilinganiso somshini, ukwakheka kwe-chip kuhlolisiswa futhi kubhekwe. Abahloli bahlole ukukhiqizwa kwe-Chip ukufakwa kwama-geometries ahlukahlukene (ama-mazak integrafy 2 esetshenzisiwe nge-PCLNL Holder kanye ne-CNMG1204122SM S05F ukuguquka kwejubane le-65 m / min.
Ikhwalithi yobuso yahlulelwa ngokwezimiso eziqinile: ubulukhuni bendawo yokwenziwa kwalesi sivivinyo akufanele ludlule i-RA = 3.2 μm, rz = 20 μm. Kufanele futhi zikhululeke ekudlidliza, ukugqokwa, noma imiphetho eyakhelwe (i-bue - ukwakha okubonakalayo kumathuluzi wokusika).
Ukuhlolwa kokushayela kwenziwa ngokusika ama-disc ambalwa kusuka ku-60 mm rod efanayo eyayisetshenziselwa izivivinyo zokuguqula. Umgodi omishini wawushaywa ngokufana ne-eksisi yenduku imizuzu engu-5 futhi ukugqokwa komhlane wangemuva kwethuluzi kwaqoshwa ngezikhathi ezithile.
Ukuhlolwa kwe-Threating kuhlola ukufaneleka kwe-sanictro engama-60 ne-625 eqinile yale nqubo ebalulekile. Zonke izimbobo ezidalwe ekuhlolweni kokumba kwangaphambilini zazisetshenziswa futhi zisikwe nge-coromant M6x1 Thread Thread. Abayisithupha balayishwe esikhungweni semishini ye-MCM evundlile ukuze bahlole izinketho zokuhlobisa okuhlukile futhi baqinisekise ukuthi bahlala beqinile umjikelezo wokuhlwitha. Ngemuva kokufaka intambo, ukukala ububanzi bomgodi ophumayo nge-caliper.
Imiphumela yokuhlola ibingathandeki: Ama-Sanicro 60 Bar aze avele ngaphandle kwe-SOOLCEENCEEN CONTEL 625 ngempilo ende kanye nokuqedwa komhlaba okungcono. Iphinde ifanise nemigoqo eqinile ku-chip ekwakhiweni, ukumba, ngokuthepha nokuthepha futhi yenziwe kahle kulezi zivivinyo.
Impilo yenkonzo yamabha alugobe ngesivinini esiphakeme kakhulu yinde emide kakhulu kunebha eliqinile futhi ngaphezulu kwamahlandla amathathu ubude kunemigoqo eqinile endaweni yokusika ye-140 m / min. Ngalesi sivinini esiphakeme, ibha eqinile yathatha imizuzu emi-5 kuphela, kuyilapho ibha engeyona inempilo yamathuluzi yemizuzu engu-16.
I-Sanicro 60 Ithuluzi Life lihlala lizinzile njengoba isivinini sokusika sanda, futhi njengoba ijubane lenyuka lisuka ezikhathini ezingama-70 liye ku-140 m / imizuzu, impilo yamathuluzi yehle nge-39% kuphela. Lokhu kuyithuluzi elifushane lama-86% lokuphila kunokuxoxisana ngo-625 ngoshintsho olufanayo ngejubane.
Ingaphezulu le-Sanicro 60 Hollow Rod Blank Shewula kakhulu kunaleso senduku eqinile eyi-625 Rod engenalutho. Lokhu kuyinjongo (ubulukhuni obungaphezulu aludluli i-RA = 3.2 μm, rz = 20 μm), futhi kulinganiswe ngonqenqemeni olubonakalayo, ukuhanjiswa komoya ngenxa yokwakhiwa kwama-chip.
I-Sanicro 60 Hollold Shank yenziwa okufanayo ne-Infoldel Informel Shank eqinile ekuhlolweni kwentambo futhi ikhombise imiphumela efanayo ngokwemibandela ye-Flank Wear kanye ne-Chip ephansi ngemuva kokumba.
Ukutholwa kusekela ngokuqinile ukuthi izinduku eziyize ziyindlela ethuthukisiwe yokunye izinduku eziqinile. I-TOOL Ithuluzi Life buhlale kathathu kunomncintiswano ngesivinini esikhulu sokusika. ISanicro 60 ayihlalanga isikhathi eside, futhi isebenza kahle, isebenza kanzima futhi ishesha ngenkathi kugcinwa ukuthembeka.
Ngokuqala kwemakethe yomhlaba wonke yokuncintisana ecindezela abasebenza ngomshini ukuthatha umbono wesikhathi eside ngokutshalwa kwezimali kwabo, ama-Sanicro 60 ukunciphisa ukugqoka kumathuluzi wemishini kumele abheke ama-margins namanani entengo ekhuthazayo. Kusho lukhulu.
Akukhona kuphela umshini isikhathi eside futhi ama-empovers ancishiswe, kepha ukusebenzisa umgogodla ongenalutho kungadlula yonke inqubo yemishini, kuqede isidingo somgodi wesikhungo, okonga isikhathi esiningi nemali.
