Amathuluzi okusika anenkomba ayaqhubeka nokuguquguquka ukusuka ekuqineni kuya ekuqedeni futhi atholakala kumathuluzi amancane obubanzi.Inzuzo esobala kakhulu yokufaka okunenkomba yikhono lazo lokwandisa ngokuphawulekayo inani lemiphetho ephumelelayo ngaphandle komzamo owedlulele ovame ukudingeka kumathuluzi ayindilinga e-carbide aqinile.
Kodwa-ke, ukuze kuzuzwe ukulawula okuhle kwe-chip, ukufakwa okunenkomba kufanele kukhethwe ngokunaka okukhethekile ohlotsheni lwempahla yokusebenza kanye nosayizi wohlelo lokusebenza, umumo, ijometri kanye nebanga, i-coating ne-nose radius.Nansi indlela imikhiqizo evela kubahlinzeki abaphambili eklanyelwe ukuhlangabezana nezimfuneko zamakhasimende zokusika insimbi efanele kusetshenziswa amathuluzi okusika ashintshashintshayo.
I-Sandvik Coromant yethule indlela entsha yokujika ye-CoroTurn Y-axis, eklanyelwe umshini womumo oyinkimbinkimbi nezimbotshana ngethuluzi elilodwa.Izinzuzo zifaka izikhathi zomjikelezo ezincishisiwe, izingxenye ezithuthukisiwe kanye nomshini ongaguquki.Indlela entsha yokuguqula isekelwe kumathuluzi amabili okusika ashintshwayo: okuhlukile okusha kwe-CoroTurn Prime, okufanelekile ku-shafts, ama-flanges kanye nezingxenye ezingaphansi;Ithuluzi le-CoroPlex YT eliwele eline-CoroTurn TR kanye ne-CoroTurn 107 efaka iphrofayili enokuxhumana kukaloliwe.Ukufakwa okujikelezayo kokucubungula izingxenye.namaphakethe kanye nezimbotshana.
Ukuthuthukiswa kokujika kwe-Y-axis kulandela impumelelo ka-Sandvik Coromant ngobuchwepheshe bayo obusha be-PrimeTurning, ukuphenduka okungaguquki kanye nokushintshashintsha kwe-interpolation, okwakhiwe ngakho okufakiwe okunenkomba okubili: I-CoroTurn enama-engeli amathathu okusika angu-35°.Umsiki we-Prime A oklanyelwe ukukhanda nokuqeda ukukhanya.nokuqeda.Ukuhlaziya: I-CoroTurn Prime B inokufakwa okunegethivu ezinhlangothini ezimbili kanye nemiphetho yokusika emine yokuqeda nokulungisa.
"Lezi ntuthuko, kuhlanganiswe namandla athuthukile emishini yesimanje kanye nesoftware ye-CAM, kuvula indlela yezindlela ezintsha zokujika kwe-Y-axis," kusho u-Staffan Lundström, umphathi womkhiqizo kwa-Sandvik Coromant Turning.“Ngamathuluzi namasu akhona manje, sibheke ngabomvu ukuhlola amathuba le ndlela engawanikeza amakhasimende ethu.”
Ukujika kwe-CoroTurn YT Y-axis kuyindlela yokujika kanyekanye ye-axis emithathu ehlanganisa i-eksisi yokuphotha kokugaya.Ithuluzi elisha lingasetshenziswa futhi “kumodi emile” futhi lifaka i-spindle yokukhiya ukuze kuguqulwe i-axis engu-2 eguquguqukayo ngokufaka inkomba esheshayo.Le ndlela ifanele zonke izinto zokwakha futhi idinga umshini wemisebenzi eminingi enenketho evumela ukufakwa kwe-axis yokugaya i-spindle ngesikhathi sokujika.Yonke imisebenzi yenziwa ngethuluzi elilodwa, okuhlanganisa ukugoqa, ukuqeda, ukuphenduka kwe-longitudinal, ukusika kanye nokwenza iphrofayela.
Ukujika kwe-eksisi engu-Y, njengoba negama liphakamisa, kusebenzisa i-eksisi ka-Y.Zontathu izimbazo zisetshenziswa kanyekanye ngesikhathi somshini.Ithuluzi lizungeza phakathi nendawo yalo.Okufakiwe kufakwa endizeni ye-YZ futhi i-eksisi ye-spindle yokugaya iyahlanganiswa phakathi nenqubo yokujika.Lokhu kwenza kube nokwenzeka ukucubungula izimo eziyinkimbinkimbi ngethuluzi elilodwa.
U-Sandvik Coromant uthi izinzuzo zokuphenduka kwe-Y-axis zihlanganisa ikhono lomshini izingxenye eziningi ngethuluzi elilodwa ngaphandle kokushintsha amathuluzi, izikhathi zokujikeleza ezincishisiwe kanye nokunciphisa ubungozi bokuhlanganisa amabala noma okungahambi kahle phakathi kwezindawo ezinomshini ezincikene.Ukufakwa kwe-Wiper kungenziwa ngendlela ebheke phezulu ukuze kudale umphumela we-Wiper ngisho nasezindaweni eziqinile.Amandla amakhulu okusika aqondiswe ku-spindle yomshini, okwandisa ukuzinza futhi anciphise ingozi yokudlidliza.I-engeli yokungena engaguquki ithuthukisa kakhulu ukulawulwa kwe-chip futhi igwema ukugxuma kwe-chip.
Uhlelo lwe-PrimeTurning lwendlela yamathuluzi lusekelwa ozakwethu be-CAM futhi lusetshenziselwa ukwakha ikhodi ye-NC elungiselelwe ukujika ngokushesha.I-PrimeTurning inconyelwe ukukhiqizwa kwevolumu ephezulu noma izingxenye ezidinga ukusethwa njalo kanye nezinguquko zamathuluzi emshinini, okuhlanganisa izikhungo zokujika, amalebula aqondile kanye nezikhungo zomshini.Ukuze uphendule izingxenye ze-cylindrical, ifaneleka kakhulu ukuguqula izingxenye ezimfushane, ezihlangene nezingxenye ezincane usebenzisa i-tailstock.Ukuphenduka kwangaphakathi, ububanzi obungaphezu kuka-40 mm kanye ne-overhang efika ku-8-10 XD kufaneleka kakhulu.Ukuhlanganisa ukujika kwe-Y-axis nokuphenduka okungaqondile, noma i-PrimeTurning, kungathuthukisa ukukhiqiza, kusho abahlinzeki.
I-Ingersoll Cutting Tools e-Rockford, e-Illinois, inikeza izixazululo ezenziwe ngokwezifiso, ezisindayo zokunemba zemishini ye-aerospace, ujantshi wesitimela, uwoyela negesi, kanye nezicelo zokuhambisa izimoto.Lokhu kuhlanganisa imikhiqizo eyenzelwe ukusetshenziswa nemishini yakamuva ye-CNC kanye nempahla yefa.
Ngokusho kwabahlinzeki, izinzuzo zokusebenzisa amathuluzi angashintshwa (uma kuqhathaniswa naqinile) zifaka:
Ukuvumelana nezimo ekukhetheni i-alloy kanye nejometri.Okufakwayo okushintshekayo kuyatholakala ngamasayizi amathiphu ahlukahlukene, amajiyometri nama-alloys ukuze afanele umgodi ofanayo.
Ukusebenza okuphezulu.Okufakiwe okunenkomba kufaka i-geometry esemaphethelweni ethuthukisiwe ukuze iqine kanye nomthwalo we-chip ophezulu.
Imishini ekhonjiswayo isetshenziswa ngokwesiko emisebenzini eminingi enzima.Kodwa-ke, ngokusho kuka-Ingersoll, ukuthuthukiswa kokunemba nezindlela zokukhiqiza nakho kuya ngokuya kuvula izinhlelo zokusebenza ekuqedeni izinhlelo zokusebenza.
Ngaphezu kwalokho, okufakwayo okungashintshwa kusiza ukusetshenziswa kokufakwa kwe-cubic boron nitride (CBN) kanye ne-polycrystalline diamond (PCD), okuqeda isidingo samathuluzi aqinile.
Amathrendi edizayini yokufaka okunenkomba ye-Ingersoll ahlanganisa amathuluzi amancane anenkomba: izigayo zomzimba owodwa ezincane njengo-0.250 in. (6.4 mm) nezigayo zokuphela ezishintshwayo kathathu ezinokufakwa okunenkomba okuncane njengo-0.375 in. (9.5 mm).Okuthuthukile kufaka phakathi amaphethelo aqinisiwe wokugwedla okunolaka, okokunamathela okungcono namajiyometri okuphakelayo okuphezulu emigqeni eminingi yokugaya nokuphenduka yomkhiqizo.Kuwo wonke uchungechunge lwe-deep hole, ibanga elisha le-IN2055 lizongena esikhundleni se-IN2005 yamanje.I-IN2055 kubikwa ukuthi inweba ukuphila kwamathuluzi kuze kufike izikhathi ezine lapho kwenziwa insimbi, insimbi engagqwali nama-alloys okushisa aphezulu.
U-Ingersoll uthi amamodeli wamathuluzi amasha anenkomba, njengabasiki besiphakeli esiphezulu nabasiki bemiphongolo, anganikeza ukukhiqiza okuphezulu kanye nekhwalithi ngoba imishini ingasebenza ngesivinini esiphezulu kanye nokuphakelayo kwetafula.Umkhiqizo ka-Ingersoll's SFeedUp uhlanganisa izici ezithuthukile ezigxile esivinini kanye nokuphakelayo okuphezulu."Imishini eminingi emisha inesivinini esiphezulu kanye ne-torque ephansi, ngakho-ke silindele ukuthambekela komshini wokuphakelayo okuphezulu nge-lighter Ap (ukujula kokusika) noma i-Ae (okuhola) ukuqhubeka," kusho uMike Dicken, umphathi womkhiqizo wokugaya.
Intuthuko ekuthuthukisweni kwamathuluzi ashintshashintshayo ithuthukise ukukhiqiza kanye nengxenye yekhwalithi.Amanye amajiyometri okufaka okuphakelayo okuphezulu angashintshaniswa namajiyometri afaka ajwayelekile kusibambi esifanayo.U-Dicken uthi i-engeli ye-helix encane ivumela amazinga aphezulu okuphakelayo ukuthi azuzwe ngokusebenzisa isimiso sokunciphisa i-chip.
Imishini ye-DeepTrio indexable gun drill yezikhungo zomshini, izintambo zokubhoboza izibhamu zithatha indawo yokubhoboza isibhamu esinesihloko se-carbide."Ama-DeepTrio indexable install gun drills ahlinzeka ngokuphindwe kasithupha kokukhiqiza futhi anciphise isikhathi sokuphumula esihambisana nezinguquko zamathuluzi," kusho uJohn Lundholm, umphathi womkhiqizo we-DeepTrio kanye nama-drills e-Ingersoll."Uma kufika isikhathi sokushintsha i-soldering gun drill bit, umshini uvala isikhathi eside.Okufakiwe kwe-DeepTrio kunemiphetho emithathu yokusika, ngakho ukukhomba kokufaka kuthatha imizuzwana embalwa esikhundleni sehora.Enye inzuzo ukuthi i-DeepTrio drill bits isebenzisa lezo Iziqondiso ezifanayo kanye nezihlahla zokusekela zisetshenziswa emishinini yokubhoboza eqinile, ngakho-ke asikho isidingo sokushintsha izingxenye zomshini,” uyaphawula.
Umshini wokufaka okunenkomba ophumelelayo uqala ngoxhumo oluqinile kwisibambi samathuluzi, kungakhathaliseki ukuthi kusemshinini omusha noma omdala ojikayo, wokugaya, wokubhola noma wokubuyisela kabusha.Kodwa imishini ethuthukisiwe ingaba nenzuzo, ngokusho kwe-Kennametal Inc. yaseLatrobe, ePennsylvania.Izikhungo ezintsha zesimanje zisebenzisa amathuluzi esistimu, njengesistimu ye-KM eyimodulayo, evumela amathuluzi ukuthi ashintshwe kalula futhi asethwe ngaphambili ngaphambi komshini ngesikhathi esincane.Imoto ayisebenzi.
Ngokuvamile, izimoto ezintsha ziyakwazi ukulawuleka futhi zinamandla ejubane eliphezulu.Amathuluzi esistimu, asebenza njengesixhumanisi phakathi komkhawulo wokusika nomshini, ayisihluthulelo sokukhiqiza okuphezulu nemiphumela.Isibonelo, i-Kennametal ithi ukuhlanganisa kwe-KM, okuklanyelwe ama-lathes aqondile, ama-lathes nezikhungo zomshini, kungenza ngokuphepha noma yimuphi umsebenzi ngaphandle kokudela umkhiqizo.
I-KM's modular tooling inikeza ukuguquguquka okukhulu, okuvumela amakhasimende ukwenza ngendlela oyifisayo umshini ukuze uvumelane nezidingo zabo.Isivinini esikhulu, ukuqina kanye nokuguquguquka kuyathandeka ezitolo zemisebenzi eminingi, okubavumela ukuthi bakhulise imbuyiselo yabo ekutshalweni kwezimali.Esinye isici esengeziwe sohlelo lwe-KM ukuhlanganisa kwe-KM4X100 noma i-KM4X63.Lokhu kuxhumana kuklanyelwe izinhlelo zokusebenza ezisindayo kusetshenziswa amathuluzi ashintshwayo futhi ahlala isikhathi eside.I-Kennametal ithi noma nini lapho izikhathi zokugoba eziphakeme noma amabanga amade kudingeka, i-KM4X100/63 iwukuxhumana okungcono kakhulu.
Intuthuko ekwakhiweni koshintsho lwamathuluzi ithuthukise ukusebenza kwamathuluzi omshini wendabuko nawesimanje.Kwethulwa amajiyometri amasha, ama-alloy, kanye nengxenye yesigaba somhwamuko ongokwenyama namakhemikhali (i-PVD ne-CVD) adinga ukulawulwa kwe-chip okuthuthukisiwe, amandla aphakeme onqenqema, nokwanda kokushisa nokumelana nokugqoka ukuze kuhlangatshezwane nezidingo zezicelo zezinto ezisetshenziswayo eziyinselele.Lokhu kufaka i-Mitral Valve (MV) ijiyomethri yomshini wensimbi, i-High-PIMS grade KCS10B ene-PVD enamathela ekushiseni okuphezulu kwama-alloys, ibanga le-KCK20B lokugaya kanye ne-KENGold KCP25C CVD yokuhlanganisa insimbi.Uphawu lokuhweba.Ngokusho kwe-Kennametal, konke lokhu kunciphisa ingozi yokuhluleka kwemishini, kwandisa ukukhiqiza futhi kunciphisa isikhathi sokunciphisa imishini, ngaleyo ndlela kwandise umkhiqizo jikelele.
Le nkampani ithe ngokuthuthuka kwe-digitalization kanye ne-Industrial 4.0, njengoba ubuchwepheshe buthuthuka, mkhulu umsebenzi osuwenziwe ekulawuleni umshini kusetshenziswa i-RFID, amathuluzi ahlakaniphile namarobhothi ukuthuthukisa amathuluzi nokwenza ngcono ukusebenza komshini..
U-Matt Hasto, Unjiniyela Wokusebenza kwa-Big Daishowa Inc. e-Hoffman Estates, e-Illinois, uthi amathuluzi okusika okufakwayo anenkomba anikeza izinzuzo ezibalulekile ngaphezu kwamathuluzi ajwayelekile ayindilinga e-carbide, kuye ngokuthi isetshenziswa kanjani.Ubalule amamaki amasha enkampani i-ACT 200 ne-ACT 300, kanye nezingubo ezintsha ze-PVD ze-chamfering, backturning, end Milling kanye nokugaya ubuso.
"Izingubo ze-PVD zihlukile ezimbotsheni ezijwayelekile," kusho u-Hasto."Kuyi-multi-layer nanoscale titanium aluminium nitride coating efakwe i-carbide ukuze kuthuthukiswe ukumelana nokugqokwa, ukwelula impilo yamathuluzi nokwandisa umkhiqizo."
Amathuluzi e-Big Daishowa chamfering ayatholakala ngezinhlobo ezimbalwa ezihlukene ukuze kuthuthukiswe ukusebenza kohlelo oluthile.Amathuluzi amancane anokufakwa okuningi avumela i-contour chamfering ngamanani okuphakelayo alungile.Abanye abasiki bane-chamfering inserts enkulu ekuvumela ukuthi ubambe ububanzi bangaphakathi bobubanzi obubanzi bembobo.
Ngokusho kwenkampani, amathuluzi e-centering ashintshwayo ahlinzeka ngokusebenza kwethuluzi okuthembekile ngokusebenza kahle kwezindleko zethuluzi elishintshwayo, elidinga kuphela ithiphu lokusika elizoshintshwa.Isibonelo, i-center cutter yohlobo lwe-C ingakwazi ukugaya ubuso, i-back chamfering ne-chamfering, iyenze ibe yithuluzi elihlukahlukene.
Izithuthukisi zakamuva ze-Big Daishowa's Ultra High Feed Chamfer Cutter manje zifaka okune okufakiwe kwe-C-Cutter Mini (esikhundleni sokubili) kanye nobubanzi obuncane kakhulu, okuvumela isivinini esiphezulu sokuphotha.U-Hasto uthi ukwandisa isibalo semikhawulo encishisiwe kungakhuphula kakhulu amanani okuphakelayo, okuholela ezikhathini zokusika ezimfishane nokongiwa kwezindleko.
"I-C-Cutter Mini isetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza, ngokuyinhloko i-chamfering kanye nokugaya ubuso, ngokusebenza kahle okuphezulu nokunemba," kusho u-Hasto."Ukushaya i-back chamfering kungenziwa kalula nge-blade eyodwa ngokungena embobeni enentambo nokushaya noma ukucwilisa imbobo engemuva kwendawo yokusebenza."
I-C-Cutter Mini inomphetho obukhali onciphisa ukudonsa kwe-blade futhi inikeza umzila oshelelayo.I-coating ayikwazi ukugqokwa, okwandisa inani lezikhathi ipuleti elingaqhutshwa ngalo amabhayisikili ngaphambi kokuthi lifakwe onqenqemeni olusha, ngokusho komphakeli.
I-Big Daishowa iphinde ibe nohlobo olulodwa lokufaka olungasuswa, lwehliselwe embobeni, futhi lugxiliswe ekudaleni izici, ithuluzi elifinyeleleka kalula lama-rake chamfers amancane, kanye nethuluzi lendawo yonke elingashintsha ama-engeli ukusuka ku-5° ukuya ku-85° kuye ngokuthi isicelo.
Noma ngabe uqeda ukugaya, ukubhola komshayeli, ukugaya nge-helical noma ukugaya ihlombe eliyisikwele, i-Big Daishowa inikeza izigayo zokuphela ezinembayo zokugaya okubushelelezi, okuthulile.Abasiki abashintshanayo banikeza imiphetho ebukhali yokusika kuzo zombili izikhombisi-ndlela ze-radial ne-axial, okusiza ukuqinisekisa ukugaya okubushelelezi, okuthulile kokuphela.Idizayini ye-BIG-PLUS yokuxhumana okukabili ihlinzeka ngokunemba okukhulu nokuba lukhuni ezinhlelweni zokusebenza ezinembayo.Wonke amamodeli aphinde abe nedizayini eyimojula enokufakwa ngokuzithandela okuhlanganisa nokuxhunywa kwe-CKB kuzinhlelo zokusebenza ezikude noma ezisindayo.
"Ama-R-Cutters ajwayelekile asebenzisa okufakwayo okunikeza umphetho obukhali wokusika futhi asuse unqenqema lwengxenye, okuholela ekuqedeni okuphezulu kwendawo yokusebenza," kusho u-Hasto.“Leli thuluzi lakha i-radial chamfer endaweni yokusebenza futhi lisetshenziselwa ukusika emuva nangaphambili.Ama-Finishing cutters aklanyelwe ukwenziwa kwevolumu ephezulu futhi avumela imiphetho emine yokusika ngokufaka ngakunye.Lokhu kusho ukuthi ukusetshenziswa kungahlehliswa. ”ngaphambi kokudinga ukushintshwa.Ukufakwa kwezindawo ezine zokuqedela okuhle kakhulu, konga isikhathi esibalulekile nemali uma kuqhathaniswa namathuluzi angashintshi.
”I-BF yethu (i-back countersink) ivamise ukusetshenziswa ezintweni zokusebenza ezidinga isithukuthezi ukuze kwakhiwe usinki ngaphandle kokuthi u-opharetha achithe isikhathi ephendula ucezu lokusebenza noma into.Ithuluzi le-BF liyakwazi ukususwa lapho lidlula embobeni, ligxilise phakathi futhi lidale usinki, bese livala futhi ukuze liphume emgodini.I-BF-Cutter yakhelwe ukubuyisela emuva izimbobo ezivaliwe ze-M6 - M30 noma 1/4 - 1 1/8 inch (6.35 - 28.6 mm) izimbobo zebholithi futhi ilungele zonke izinhlobo zensimbi.( Ilungele ukusetshenziswa ensimbi engagqwali, insimbi eyinsimbi kanye ne-aluminium, phakathi kokunye, amamaki e-blade akamuva avumela ukukhethwa ngokucophelela okusekelwe ezintweni kanye nezimo zekhwalithi ephezulu kanye nempilo yesevisi,” kusho u-Hasto.
