Indlela yokucophelela, ukucabanga kwesimanjemanje, ukusetha ngaphambilini ungaxhunyiwe ku-inthanethi kanye nokugxila kokupholisa kanye nama-chips kuvula amandla wakamuva ashintshekayo wamathiphu omshini we-CNC deep hole machining.
Izindlela zokuprakthiza zamathiphu ashintshekayo zinikeza ukuguquguquka nokonga kwezindleko uma usebenza ngamadayimitha amakhulu uma kuqhathaniswa nokubhola okuqinile.Lapha, umshini wokushayela we-TA ovela ku-Allied Machine & Engineering wenza isikhunta sezimoto esisansimbi se-P20.Imbobo izovaleka futhi igcwaliswe ngamanzi ukuqinisekisa ukupholisa okufanele.
Izidleke zezinyoni zingaba omunye wemiphumela yokungabi nolaka ngokwanele ekuphakeleni okuncane, njengoba kubonakala ngensimbi engu-1018 emnene.
CNC umshini wokumba weplani ngekhono eliphezulu.
Uma i-drill isebenza kahle, ama-chips ayafinyeza futhi ahlukanise, agcine umbala wawo wangempela.
Isiteji esiphezulu sesistimu yokubhoboza ye-Allied enokufakwa kwe-TA sihlanganisa umshini ozishayelayo ofakwe i-carbide eduze komzimba ukuze kuqinisekiswe ukuzinza kwethuluzi.Le modeli, ebizwa ngokuthi i-Stealth Drill, iphinde ibe nezindawo zokupholisa ezengeziwe kanye nephinikhodi eguquguqukayo enyakazisa okufakiwe ukuze kuncishiswe ukugqagqana kokubekezelelana okuvamile kuwo wonke amathiphu wokuprakthiza.
Ukufaka izinkomba kumathuluzi omshini ukuze kukale ubude bebhithi nokuphuma kwayo kungase kube ukumosha, kube namaphutha, futhi kube yingozi.Izisetha zedijithali zingaqeda lezi zinkinga.
Ukusetha ngaphambilini kwedijithali ngokuvamile kunikeza ukunemba okukhulu kunezinkomba, kanye nesofthiwe eqondisa umsebenzisi ngenqubo yokulinganisa.
CNC umshini wokumba weplani ngekhwalithi enhle.
Ukuqinisekisa ukuphepha nokunemba kokusebenza kwe-TA esikhundleni, i-Allied incoma ukubhoboza imbobo yokuhlola okungenani ukujula okungu-2xD.Lo mkhuba uhlinzeka ngokuzibandakanya okwanele ukugcina i-drill igxile futhi ivimbele ekubeni inganono uma iphuka.Ama-drill amade kufanele anikezwe ngokudla okungadluli ku-50 rpm kanye nama-intshi angu-12 ngomzuzu (300 mm/min) njengoba kubonisiwe kuze kube yilapho ichopho lingaphakathi kwe-1/16 intshi (1.5 mm) yezimbobo ezingezansi.Kusukela kuleli phuzu kuqhubeke, umsebenzisi kufanele agcine u-50% wejubane elinconyiwe kanye no-25% wokuphakelayo okunconyiwe kuze kube yilapho umshini wokubhola ufinyelela ukujula okulingana nobubanzi bakho.Ijubane kumele lehliswe libe ngu-50 rpm ngaphambi kokuphuma emgodini.
“Nakuba amakhasimende ethu efuna ukuthi i-drill ibe ithuluzi lokuqeda, kuseyithuluzi elinzima,“ kusho uSalvatore DeLuca, umphathi womkhiqizo we-Allied Machine and Engineering."Kuzohlala kuncane kakhulu."
Noma kunjalo, uthi, kulula ukuqonda izimfuno eziphakeme ezibekwe ekuzilolongeni kwamathiphu ashintshashintshayo, njengalezo ezenziwe yi-Allied, uchwepheshe wamathuluzi okubhoboza.Uma isetshenziswe kahle, imikhiqizo yakamuva ingenza izimbobo ziqonde futhi zibushelelezi ngokwanele ukuthi amathuluzi okuqeda akhethekile awadingeki.
Kodwa-ke, ukubhola okunembile nokusebenza kahle kubaluleke kakhulu kunethuluzi ngokwalo, ikakhulukazi emigodini enezilinganiso zokujula nobubanzi obungu-9:1 nangaphezulu.Enkulumweni eyisihluthulelo yakamuva, uMnu. DeLuca ubeke izincomo ezinhlanu zokubhoboza okujulile ngohlelo lwe-TA lwenkampani, izinhlobonhlobo zezinsimbi ezishintshayo eziklanyelwe ukubhoboza izinsimbi eziningi, insimbi yokusansimbi, ama-alloys okushisa aphezulu nama-alloys e-aluminium.
CNC umshini wokumba weplani ilungele imboni yakho.
Lapho imbobo ijula, i-drill iba yinde.Uma i-drill iba yinde (ibanga elikhulu phakathi kwephuzu lethuluzi nekhala lokuphotha), ukuphuma okuningi kuzothinta imiphumela.Kwezinye izinhlelo zokusebenza zomshini wembobo ejulile, ukudlidliza okuncane kungabangela ukuguga kwamathuluzi ngaphambi kwesikhathi futhi kuthinte ubuqotho nokuqedwa kwendawo.
Kodwa-ke, isidingo sokushuna ngokucophelela akusona isizathu sokuchitha isikhathi esiningi ukhomba futhi ulungisa ukuphela njalo lapho ushintsha amathuluzi noma izindwani.Ikakhulukazi, endaweni yezimboni zanamuhla ayikho indawo yokukhuphuka endaweni yokusebenza ukuze umise inkomba, noma ubeke ucezu lwephepha ukuze uqalise ithuluzi.Ukuhlanganisa amathuluzi ungaxhunyiwe ku-inthanethi ngesethi yangaphambili kungonga isikhathi esiningi kunoma yimuphi umsebenzi wokumba ojulile.
Endaweni yokukhiqiza yanamuhla, ayikho indawo yokufinyelela endaweni yokusebenza ukuze umise inkomba, noma ubambe ipheshana endaweni ukuze uqalise ithuluzi.
Ngaphezu kokulondoloza isikhathi, ukwenza kube lula ukuthola nokulinganisa izibonelelo zokumba kuvimbela amaphutha abizayo.“Ngokubona kwami, ukufakwa kalula nje kuwufanele ukutshalwa kwezimali,“ kusho uMnu uDe Luca.“Uma ubona ukwehliswa kwezindleko zokusetha kanye nesikhathi sokuncipha kwemishini ngenxa yezilinganiso zokusetha ezingalungile, kunzima ukucabanga ukuthi awunaso isifudumezi-moya.”
Endaweni yeklayenti elilodwa, imishini emithathu eshintshashintshayo yethiphu yomshini Ohlangene (eqanjwe ngokusebenza kwayo ngokuthula) ifakwa egumbini lamathuluzi ekuqaleni kweshifu ngayinye.Le nqubo ithatha imizuzu engaphansi kweyi-10.Ngokuphambene, ukusetha amathuluzi amathathu emugqeni wokukhiqiza kungathatha imizuzu engama-30, okulingana nemizuzu engama-90 yesikhathi esichithiwe ngamashifu amathathu.Ngokukhiqizwa okungu-24/7, lokhu kubalelwa kumahora acishe abe ngu-2,200 ngonyaka (lesi sibalo asibandakanyi isikhathi sokuphumula somshini lapho ushintsha amathuluzi).“Isistimu ye-pre-conditioning ingabalela u-5% waleso sikhathi esilahlekile,“ kusho uMnu DeLuca.
Kulokhu, i-Stealth Drill ngokwayo inyusa ukonga isikhathi okunikezwa ukusetha okungaxhunyiwe ku-inthanethi.I-drill ifakwe izikhonkwane eziguquguqukayo ezinyakazisa i-blade ukuze kuncishiswe ukunqwabelana kokubekezelelana okuvamile kuwo wonke ama-tip drill ashintshashintshayo.Ngakho-ke, ukususa ukuphelelwa amandla akusadingi ukuqaqa nokuhlanza izingxenye zamathuluzi, ukulungisa ama-offset, ukungeza ama-shim kuma-turrets, noma ukuthi omakhenikha abanolwazi bazame izixazululo zangokwezifiso.
Ngaphandle kolunye uhlobo lombono we-X-ray, ukwakheka kwe-chip kuwukuphela kwendlela yokusho ukuthi umshini wokubhoboza usebenza kanjani ngenkathi usika, futhi usenesikhathi sokuthatha isinyathelo.Ama-curly shapes (njengama-“six” kanye “nama-nines”) alungile, kuyilapho amade, ama-chips azacile angasebenzi kahle ekususeni ukushisa endaweni yokusika.Umbala nawo ubalulekile.Ama-chips kancane kancane aphenduka abe mpunga, amnyama futhi aluhlaza okwesibhakabhaka njengoba indawo yokusika ishisa kakhulu.Ama-chips ashintshe umbala angase abonise isidingo sokunciphisa ukushisa ngokwehlisa isivinini sokuphotha, kuyilapho ama-chips anamathelayo angase abonise isidingo sokwandisa izinga lokuphakelayo kuze kufike lapho kuphuka khona okokusebenza kunokuba kugqabhuke.
Ezinye izindaba zinganakwa kalula.“Enye yezinto ezibukelwa phansi kakhulu kunoma iyiphi inqubo yokwenza imishini, ngisho nangaphandle kokumba, ipholile,“ kusho uMnu DeLuca.Uma kubhekwa umthelela obalulekile wokupholisa ekwakhekeni kwe-chip, ukulungisa ukugxilisa nokugeleza kwesipholile nakho kungasiza ekushintsheni umbala kwesidleke senyoni.
“Enye yezinto ezibukelwa phansi kakhulu ezithinta noma iyiphi inqubo yokwenza imishini, ngisho nangaphandle kokumba, ipholile.“
I-Hot Selling CNC umshini wokumba weplani.
Izinto ezipholile ezincibilikayo emanzini zisetshenziswa kakhulu ezintweni ezijwayelekile ngoba ziqeda ukushisa kahle.Kodwa-ke, kwezinye izimo ukwakheka kwe-semi-synthetic noma uwoyela wonke kungase kube ukukhetha okungcono kakhulu kokugcotshwa okuthuthukisiwe nama-chips amafushane, ahlukene.Nakuba amathuluzi angase agqoke ngokushesha futhi izilungiselelo kudingeka zingabi nolaka kunezipholile ezisekelwe emanzini, ama-blade ukumelana nokushisa angasiza ukulungisa lokhu.Konke kuncike kuhlelo lokusebenza.
Isici esingenakuphikwa ukusetshenziswa kwama-drill ane-coolant.Umshini kufanele futhi unikeze ingcindezi eyanele yokupholisa.Ama-drill amancane adinga ingcindezi ye-chip eyengeziwe ukuze ahambisane nokukhishwa kwezinto ezibonakalayo ngoba kufanele agijime nge-RPM ephezulu ukuze afinyelele isivinini esifana nesendawo njengamathuluzi amakhulu.“Lapho umfutho uphezulu, kulapho ama-chips aphuma ngokushesha embobeni futhi lapho ungakwazi ukujika kancane kancane,“ kusho uMnu De Luca.
Ama-Allied TA drill ayatholakala ngamajiyometri ajwayelekile okufaka ajwayelekile angu-187 nezinhlanganisela zokumboza, futhi leli yibhokisi lamathuluzi lomkhiqizi oyedwa nje.Njengoba kunezinketho eziningi kangaka eziqondene nohlelo lokusebenza ezitholakalayo, isu lokufaka-ibhola elake laba yinqubo evamile lingase lingasasebenzi.
Isibonelo ukukhotha.Asikho isidingo sokushintsha ngezikhathi ezithile isiqondiso sokuphakelayo kwethuluzi ngesikhathi sokusika ukuze uqinisekise ukukhishwa kwama-chips emgodini.“Manje uma ubona ukucofa, kuvame ukuba umuntu osebenzise kabi ithuluzi noma osebenzise ithuluzi elingalungile ngokuphelele,” kusho uMnu. De Luca.
“Manje uma ubona ukucofa, ngokuvamile kuba othile osebenzisa ithuluzi ngendlela engafanele, noma osebenzisa ithuluzi elingafanele.”
Uma singekho isikhathi sokuthenga amathuluzi amasha noma ukwenza ezinye izinguquko zenqubo, ukubhobhoza kungase kube ukuphela kwenketho.Nokho, ukubhola kuhlala kuhamba kancane ngenxa yalokho.Futhi, ukuhoxisa ithuluzi ngenkathi ukusika kungashiya i-chip eyakhelwe kancane, engahlukanisiwe emgodini.I-Carbide ayigugi kodwa ishwabene uma kuqhathaniswa, futhi lesi sakhiwo singenza ukufakwa kuthambekele ekuhlulekeni ngaphambi kwesikhathi ngisho nenhlekelele uma kubhekene nokuchayeka okuphindaphindiwe kule ndawo emagebhugebhu, engalingani.Ngisho noma i-blade iphelele, i-workpiece ingase yonakale.Njengoba kushiwo ngenhla, ama-drill bits amaningi kakhulu.“Mhlawumbe izinkulungwane ezimbalwa kuphela (1″ u = 0.001 amayintshi), kodwa kweminye imisebenzi kusengaba nengozi yokushiya izibazi ngaphakathi kwembobo noma ukusika imbobo ibe mkhulu kakhulu,“ uyachaza.
Omunye umkhuba ophelelwe yisikhathi ukusebenzisa izimbobo zamabala ezincane ezinobubanzi obungama-degree angama-90 njengezimbobo zokuhlola.Lokhu kwenza umqondo onembile futhi, njengokuchofa, kuhlala kuwumthetho owusizo wesithupha osetshenziswayo wamathuluzi.Phela, izimbobo ezincane ezisuka kancane phakathi nendawo kulula ukuzilungisa kunezimbobo ezinkulu, futhi amakhona acijile asiza ukubhoboza ukungena futhi kubambe ingxenye ngokushesha futhi kalula.Kodwa-ke, ukunemba kokuma kwemishini eminingi ye-CNC kwanele ukuqinisekisa ukuthi umshini wokubhoboza unobubanzi obufanayo ne-drill eyinhloko.Futhi anamandla ngokwanele ukushayela amaphuzu aluhlaza ku-workpiece yasekuqaleni.
Eqinisweni, amabhithi amaningi okubhoboza anenkomba ane-engeli yephoyinti engaphansi kuka-90 degrees.Ngakho-ke, ukufakwa kuthinta ububanzi bembobo enkulu phambi kwendawo yokuzenzela.“Uma ubungasebenzisa elinye lamathuluzi ethu ajwayelekile okumba amabala, intwana yethu ibizonyakaza kancane, ibangele ukuguga ngaphambi kwesikhathi kanye nokwehla kwamathuluzi okungenzeka,“ UMnu. DeLuca wachaza.“Ukusebenzisa i-blade diameter efanayo kanye ne-engeli yephoyinti kuqinisekisa ukuthi i-drill ende ilingana kahle lapho ukubhola kuma khona.“
Lapho ukubhola okujulile, ukusheshisa ngokushesha isivinini esigcwele kanye nokuphakelayo kudala ingozi yokuphepha futhi kungase kuphazamise ukusebenza.Ngakho-ke iningi lezincomo ezijwayelekile ze-Allied ngenjongo evamile yokuprakthiza okunezinkomba zingafingqwa ngomusho owodwa: sondela embobeni yokuhlola ngokucophelela.Bona izithombe kugalari ngenhla ukuze uthole imininingwane eyengeziwe.
“Ukusondela ngokucophelela embobeni ekhona ngaphambili kungasiza ukugwema isibazi noma ukulimala,“ UMnu. De Luca uthe ngezincomo.“Lokhu kuvumela unqenqema lwe-drill ukuthintana nezinto ngaphambi kokuthi unyuse isivinini.Imbobo isebenza njengomkhono, igxilisa i-drill futhi igcine izingxenye kanye nabantu bephephile. "
Ukudala izimbobo ezinezintambo kuma-alloys e-titanium, izindlela ezifanele ziyadingeka ngokusekelwe ekuqondeni izakhiwo zalezi zinto kanye nezici zenqubo yokuhlanganisa.
Ukuthuthela ekujikeni kanzima, udinga ukushintsha usuke ekufakeni i-carbide uye kokufakwa kwe-CBN, kodwa kulula (futhi kuyathengeka) kunalokho ucabanga.Ishintshela esivinini esiphezulu, okungase kukubeke eceleni.Asikho isidingo.Yingakho ke.
Enye yezindlela ezivame kakhulu zokulutha ezisetshenziswa emishinini ye-CNC namuhla “iwukucupha okuqinile” noma “ukucupha kanyekanye”.Imijikelezo yokuthepha eqinile ivumelanisa ukujikeleza kokuphotha komshini kanye nokuphakelayo ngokuya ngephimbo elithile.Njengoba okuphakelayo okungena emgodini kuvumelana, ngokombono kungenzeka ukusebenzisa i-gripper eqinile ngaphandle kokucindezelwa okuqinile.
