Indlela enonyameko, ukucinga kwangoku, ukusetha kwangaphambili okungaxhunyiwe kwi-intanethi kunye nokugxila kwizinto ezipholileyo kunye neetshiphusi zivula amandla oqeqesho lwamva nje olunokutshintshwa lwe-CNC ye-hole machining.
Iingcebiso zoqheliso ezitshintshayo zibonelela ngokuguquguquka kunye nokonga kweendleko xa usebenza ngeedayamitha ezinkulu xa kuthelekiswa noqheliso oluqinileyo.Apha, umatshini wokulingwa we-TA ovela kwi-Allied Machine & Engineering wenza i-P20 cast steel automotive mold.Umngxuma uya kuvaleka kwaye uzaliswe ngamanzi ukuqinisekisa ukupholisa okufanelekileyo.
Iindlwane zeentaka zinokuba sesinye seziphumo zokungabi ndlongondlongo ngokwaneleyo kwi-bit feed, njengoko kubonwa nge-1018 yentsimbi emnene.
CNC umatshini wokomba ocwangcisiweyo ngobuchule obuphezulu.
Ukuba i-drill isebenza ngokuchanekileyo, iitshiphusi zifutshane kunye necandelo, zigcina umbala wazo wokuqala.
Inqanaba eliphezulu le-Allied drilling system kunye nokufakwa kwe-TA kubandakanya i-self-driving drill kunye nokufakwa kwe-carbide kunye nomzimba ukuqinisekisa ukuzinza kwesixhobo.Le modeli, ebizwa ngokuba yi-Stealth Drill, ikwaneendawo zokupholisa ezongezelelweyo kunye nephini eliguquguqukayo elihambisa into efakwayo ngeradially ukunciphisa ukunyamezelana ukugqithelana okuqhelekileyo kuzo zonke iingcebiso ezitshintshayo zoqheliso.
Ukufakela izikhombisi kwizixhobo zoomatshini ukulinganisa ubude besuntswana kunye nokubaleka kunokuba yinkcitho, kuqheleke ukwenza iimpazamo, kwaye kunokuba yingozi.Abaseta bedijithali banokuphelisa ezi ngxaki.
Ukusetwa kwangaphambili kwedijithali ngokuqhelekileyo kunika ukuchaneka okukhulu kunezikhombisi, kunye nesofthiwe ekhokela umsebenzisi ngenkqubo yokulinganisa.
CNC umatshini wokomba ocwangcisiweyo ngomgangatho omhle.
Ukuqinisekisa ukhuseleko kunye nokuchaneka kokutshintshwa kwe-TA drills, i-Allied incoma ukugrumba umngxuma wokulinga ubuncinci obuyi-2xD ubunzulu.Esi senzo sibonelela ngokuzibandakanya okwaneleyo ukugcina i-drill igxile kwaye ithintele ekubeni ibe yi-cannonball xa iqhekeza.Iidrill ezinde kufuneka zondliwe ngokungekho ngaphezulu kwe-50 rpm kunye ne-12 intshi ngomzuzu (300 mm/min) njengoko kubonisiwe de incam ibe ngaphakathi kwe-1/16 intshi (1.5 mm) yemingxuma engezantsi.Ukusuka kweli nqanaba, umsebenzisi kufuneka agcine i-50% yesantya esicetyiswayo kunye ne-25% yesondlo esicetyiswayo de i-drill ifike kubunzulu obulingana nobubanzi bayo.Isantya kufuneka sincitshiswe ukuya kwi-50 rpm ngaphambi kokuba uphume emngxunyeni.
“Ngelixa abathengi bethu befuna ukuba i-drill ibe sisixhobo sokugqiba, isesisixhobo esirhabaxa,“ utshilo uSalvatore DeLuca, umphathi wemveliso yeAllied Machine and Engineering."Kuya kuhlala kuncinci."
Sekunjalo, uthi, kulula ukuqonda iimfuno eziphezulu ezibekwe kwiingcebiso ezitshintshisayo, ezifana nezo zenziwe yi-Allied, ingcali yesixhobo sokukrazula imingxunya.Xa isetyenziswe ngokuchanekileyo, iimveliso zamva nje zinokwenza imingxuma iqonde kwaye igudileyo ngokwaneleyo ukuba izixhobo ezikhethekileyo zokugqiba azifunwa.
Nangona kunjalo, ukugrumba okuchanekileyo kunye nokusebenzayo kubaluleke kakhulu kunesixhobo ngokwaso, ngakumbi kwimingxuma enobunzulu ukuya kwi-diameter ratios ye-9: 1 nangaphezulu.Kwinqaku eliphambili lamva nje, uMnu. DeLuca ubeke iingcebiso ezintlanu zokomba ngokunzulu kunye neNkqubo ye-TA yenkampani, uluhlu olubanzi lweebhithi ezitshintshileyo ezilungiselelwe ukugrumba kwiintsimbi ezininzi, intsimbi ekhandiweyo, iialloyi zobushushu obuphezulu kunye nealloys zealuminium.
CNC umatshini wokomba ocwangcisiweyo ilungele umzi-mveliso wakho.
Okukhona unzulu umngxuma, kokukhona i-drill inde.Xa i-drill ithatha ixesha elide (umgama omkhulu phakathi kwesixhobo kunye nempumlo yokuphotha), ukukhutshwa okungaphezulu kuya kuchaphazela iziphumo.Kwezinye usetyenziso lwemingxuma enzulu, ukungcangcazela okuncinci kunokubangela ukunxitywa kwesixhobo kwangaphambi kwexesha kwaye kuchaphazele ukuthi tye kunye nokugqitywa komphezulu.
Nangona kunjalo, imfuno yokulungiswa ngononophelo ayisosizathu sokuchitha ixesha elininzi uchonga kwaye ulungisa ukuphuma rhoqo xa utshintsha izixhobo okanye iiblade.Ngokukodwa, kwindawo yoshishino lwanamhlanje akukho ndawo yokunyuka kwindawo yokusebenza ukuseta isalathisi, okanye ubeke isiqwenga sephepha ukuze uqalise isixhobo.Ukudibanisa izixhobo ngaphandle kwe-intanethi kunye ne-pre-setter kunokonga ixesha elininzi kuwo nawuphi na umsebenzi onzulu wokomba.
Kwimeko yokuvelisa yanamhlanje, akukho ndawo yokufikelela kwindawo yokusebenza ukuseta isalathisi, okanye ukubamba isiqwenga sephepha kwindawo yokuqalisa isixhobo.
Ukongeza ekongeni ixesha, ukwenza kube lula ukufumana nokulinganisa izibonelelo zokomba kuthintela iimpazamo ezibiza kakhulu.“Ngokombono wam, ukukhululeka kokufakela kuphela kuwufanele utyalo-mali,“ watsho uMnumzana De Luca.“Xa ubona ukuthotywa kweendleko zokuseta kunye nexesha lokuncipha kwezixhobo ngenxa yemilinganiselo yokuseta engachanekanga, kunzima ukucinga ukuba awunaso isixhobo somoya.”
Kwisiza somxumi omnye, iidrili ezintathu zoomatshini boManyeneyo otshintshisanayo (ezithiywe ngomsebenzi wazo ozolileyo) zifakelwe kwigumbi lesixhobo ekuqaleni kweshifti nganye.Le nkqubo ithatha ngaphantsi kwemizuzu eyi-10.Ngokwahlukileyo, ukuseta izixhobo ezithathu kumgca wemveliso kunokuthatha imizuzu engama-30, elingana nemizuzu engama-90 yokuchitha ixesha elichithwe kathathu.Ngemveliso ye-24/7, oku kufikelela phantse kwiiyure ezingama-2,200 ngonyaka (eli nani alibandakanyi ixesha lokunciphisa umatshini xa utshintsha izixhobo).“Inkqubo ye-pre-conditioning ingenza i-5% yaloo lahleko yexesha,“ watsho uMnumzana DeLuca.
Kule meko, iStealth Drill ngokwayo yonyusa ugcino lwexesha olunikezelwa ngokuseta ngaphandle kweintanethi.I-drill ixhotyiswe ngezikhonkwane eziguquguqukayo ezihambisa i-blade radially ukunciphisa ukunyamezela ukunyamezela okuqhelekileyo kunye nazo zonke ii-tip drills ezitshintshayo.Ke ngoko, ukuphelisa ukubaleka akusafuni kuqhawuka kunye nokucoca izixhobo zesixhobo, uhlengahlengiso olulungelelanisiweyo, ukongeza i-shims kwi-turrets, okanye ukuba noomatshini abanamava bazame izisombululo zesiko.
Ngaphandle kolunye uhlobo lombono we-X-ray, ukubunjwa kwetshiphu kuphela kwendlela yokuxela ukuba i-drill iqhuba njani ngelixa usika, kwaye usenalo ixesha lokwenza.Iimilo ezigobileyo (ezifana ne "sixes" kunye ne "nines") zifanelekile, ngelixa ixesha elide, ii-chips ezincinci zingasebenzi kakuhle ekususeni ukushisa kwindawo yokusika.Umbala nawo ubalulekile.Ii-chips ngokuthe ngcembe zijika zibe ngwevu, zimnyama kunye nebhlowu njengoko indawo yokusika igqithisa.Iitshiphusi ezigudileyo zinokubonisa imfuneko yokunciphisa ubushushu ngokunciphisa isantya sokusonta, ngelixa iitshiphusi ezincangathi zinokubonisa imfuneko yokunyusa izinga lokutya ukuya kwindawo apho i-workpiece iqhawuka khona kunokuba igqabhuke.
Eminye imiba inokungahoywa ngokulula.“Enye yezona zinto zijongelwa phantsi kuyo nayiphi na inkqubo yomatshini, nangaphandle kokugrumba, kukupholisa,“ watsho uMnumzana DeLuca.Xa kujongwa isiphumo esibalulekileyo sesisipholisi ekwenziweni kwetshiphu, ukulungelelanisa ukugxila kunye nokuhamba kwesisipholisi nako kunokunceda ekutshintsheni umbala kwendlwane yeentaka.
“Enye yezona zinto zijongelwa phantsi ezichaphazela nayiphi na inkqubo yomatshini, nangaphandle kokomba, kukupholisa.“
Ukuthengisa Okushushu kwe-CNC umatshini wokomba ocwangcisiweyo.
Izizipholisi ezinyibilikayo emanzini ziqheleke ukusetyenziswa kwinjongo jikelele kuba zikhupha ubushushu kakuhle.Nangona kunjalo, kwezinye iimeko i-semi-synthetic okanye i-oyile yonke inokuba lolona khetho lungcono lokuphucula ukuthambisa kunye neechips ezimfutshane, ezicandekileyo.Ngelixa izixhobo zinokunxiba ngokukhawuleza kwaye iisetingi kufuneka zingabi ndlongondlongo kunezipholisi ezisekwe emanzini, iileyiti ezinokumelana nobushushu zinokunceda ukulungisa oku.Konke kuxhomekeke kwisicelo.
Umba ongenakuphikiswa kukusetyenziswa kweedrili ezinesipholisi.Umatshini kufuneka kwakhona unike uxinzelelo olwaneleyo lokupholisa.Iidrill ezincinci zifuna uxinzelelo olungakumbi lwe-chip ukuze ziqhubeke nokususwa kwezinto kuba kufuneka zibaleke kwi-RPM ephezulu ukufezekisa isantya esifanayo somphezulu njengezixhobo ezinkulu.“Ukuphakama koxinzelelo, ngokukhawuleza iitshiphusi ziphuma emngxunyeni kwaye ngokukhawuleza unokujika kancinci,“ watsho uMnumzana De Luca.
I-Allied TA drills iyafumaneka kunye ne-187 eyahlukeneyo ye-geometries esemgangathweni yokufaka kunye nendibaniselwano yokugquma, kwaye le yibhokisi yezixhobo zomenzi omnye.Ngokhetho oluninzi oluthe ngqo olukhoyo olukhoyo, isicwangciso sobuchule sokufaka i-insert-drill esasifudula siyinkqubo eqhelekileyo sinokungasasebenzi.
Umzekelo kukugqogqa.Akukho mfuneko yokutshintsha ngamaxesha athile isalathiso sokutya kwesixhobo ngexesha lokusika ukuze kuqinisekiswe ukususwa kwee-chips emngxunyeni.“Ngoku xa ubona ukukrola, kudla ngokuba ngumntu osebenzise isixhobo kakubi okanye osebenzise isixhobo esingafanelekanga ngokupheleleyo,” utshilo uMnu. De Luca.
Ngoku xa ubona ukukrola, idla ngokuba ngumntu osebenzisa isixhobo ngendlela engafanelekanga, okanye osebenzisa isixhobo esingafanelekanga.”
Xa kungekho xesha lokuthenga izixhobo ezitsha okanye ukwenza olunye utshintsho lwenkqubo, ukucofa isenokuba yeyona ndlela ikhethwayo.Nangona kunjalo, ukugrumba kuhlala kucotha ngenxa yoko.Kwakhona, ukuhoxisa isixhobo ngelixa ukusika kunokushiya i-chip edibeneyo, engahluliweyo emngxunyeni.I-Carbide iyakwazi ukumelana nokunxitywa kodwa i-brittle ngokwentelekiso, kwaye le propati inokwenza ukuba ukufakwa kuthande ukuba ngaphambi kwexesha kunye nokusilela okuyintlekele xa iphantsi kokuvezwa okuphindaphindiweyo kulo mhlaba ujijekileyo, ongalinganiyo.Nokuba i-blade ilungile, i-workpiece inokonakala.Njengoko sele kukhankanyiwe ngasentla, uninzi lwezixhobo zokomba zinobukhulu obugqithileyo.“Mhlawumbi ngamawaka ambalwa kuphela (1″ u = 0.001 intshi), kodwa kweminye imisebenzi kusekho umngcipheko wokushiya amanxeba ngaphakathi emngxunyeni okanye ukusika umngxuma ube mkhulu kakhulu,“ uyachaza.
Olunye uqheliselo oluphelelwe lixesha kukusebenzisa iidridi zamabala ezinobukhulu obungama-90 njengemingxuma yokulinga.Oku kwenza ingqiqo kwaye, njengoko kukrolwa, kuhlala kungumgaqo oluncedo wosetyenziso lwesixhobo.Emva kwayo yonke loo nto, imingxuma emincinci ephuma kancinci embindini kulula ukuyilungisa kunemingxuma emikhulu, kwaye iikona ezibukhali zinceda i-drill ingene kwaye ibambe inxalenye ngokukhawuleza nangokulula.Nangona kunjalo, ukuchaneka kokumiswa koomatshini abaninzi be-CNC kwanele ukuqinisekisa ukuba i-pilot drill inobubanzi obufanayo kunye ne-drill engundoqo.Zikwanamandla ngokwaneleyo ukuba aqhube amanqaku abuthuntu kwizinto zokuqala zokusebenza.
Ngapha koko, uninzi lwamasuntswana e-drill anesalathiso esine-self-centering bits ene-point angle engaphantsi kwe-90 degrees.Ngoko ke, ukufakwa kuchaphazela ububanzi bomngxuma omkhulu phambi kwendawo yokuzimela.“Ukuba ubunokusebenzisa esinye sezixhobo zethu zokomba ezisemgangathweni, intwana yethu iya kuhamba kancinci, ibangele ukunxitywa kwangaphambi kwexesha kunye nokuhla kwesixhobo esinokwenzeka,“ UMnu. DeLuca wacacisa.“Ukusebenzisa i-blade blade diameter kunye ne-engile yencam kuqinisekisa ukuba i-drill emide ingena ngokugqibeleleyo apho kumisa khona ukomba.“
Xa ukugrumba okunzulu, ngokukhawuleza ukukhawulezisa kwisantya esipheleleyo kunye nokutya kudala ingozi yokhuseleko kwaye kunokuchaphazela ukusebenza.Ke ngoko uninzi lweengcebiso ezisemgangathweni ze-Allied zenjongo ngokubanzi zoqheliso oluphawulweyo zinokushwankathelwa kwisivakalisi esinye: sondela kumngxuma wokulinga ngononophelo.Bona iifoto kwigalari engentla ngeenkcukacha ezithe vetshe.
“Ukusondela ngononophelo kumngxunya osele ukhona kunokunceda ukuphepha amanxeba okanye umonakalo,“ UMnu De Luca uthe ngeengcebiso."Oku kuvumela umda we-drill ukuba uqhagamshelane nezinto ngaphambi kokuba uthathe isantya.Umngxuma usebenza njengomkhono, ugxile kwindawo yokusebenzela kunye nokugcina iindawo kunye nabantu bekhuselekile. "
Ukudala imingxuma enemisonto kwi-titanium alloys, iindlela ezifanelekileyo ziyafuneka ngokusekelwe ekuqondeni iimpawu zezi zinto kunye neempawu zenkqubo yokudibanisa.
Ukufudukela ekujikeni okunzima, kufuneka utshintshe kwi-carbide ukuya kwi-CBN inserts, kodwa kulula (kwaye ifikeleleke ngakumbi) kunokuba ucinga.Itshintshela kwizantya eziphezulu zomphezulu, ezinokukubeka kude.akukho mfuneko.kunjalo ngoba.
Enye yezona ndlela zixhaphakileyo zokuthunga ezisetyenziswa koomatshini be-CNC namhlanje "yi-trigid threading" okanye "intambo edibeneyo".Imijikelo engqongqo yokucofa ingqamanisa ukujikeleziswa komatshini wokusonta kunye nokutya ngokwenowuthi ethile.Kuba ukutya kumngxunya kuhambelana, kuyenzeka ngokwethiyori ukuba kusetyenziswe into yokubamba eqinileyo ngaphandle koxinzelelo loxinzelelo.
