Xa abantu abaninzi besiva 'indawo yokwenza izinto zentsimbi estainless steel', baba nomfanekiso wento emenyezelayo, eqinileyo, kwaye ethe ngqo ukuyenza. Leyo yimbono yokuqala ephosakeleyo. Inyaniso kukuba, insimbi engenasici yintsapho, akukho nto enye, kunye ne-machining 304 lihlabathi ngaphandle kokujongana ne-316L okanye, unkulunkulu makangavumeli, i-17-4 PH. Inxalenye 'engenasici' ikukhohlisela ekubeni ucinge ukuba yonke into imalunga nokuxhathisa umhlwa, kodwa kumgangatho wevenkile, imalunga nokwenza lukhuni, ulawulo lwetshiphu, kunye nokulawula ubushushu. Ndibone imizobo emininzi ingena 'ingenasici' echaziweyo, kulapho iintloko ziqala khona. Kuya kufuneka ubuze, okanye ulungiselela imfumba ye-scrap.
IMaze yeMpandla: Ayinasiphelo nje
Makhe sicacise. Amanqaku e-Austenitic afana ne-304 kunye ne-316 zizinto eziqhelekileyo. Bayintsini. Abaqhekezi iitshiphusi kakuhle; benza iiribhoni ezinde, ezineentambo ezinokuthi zijikelezise, zonakalise umphetho, kwaye ziyingozi yokhuseleko. Ukutya kwakho kunye nezantya kufuneka zilungile-zicotha kakhulu, kwaye usebenza-nzima phezulu, wenze i-pass elandelayo ibe nenkohlakalo kwisixhobo; ngokukhawuleza kakhulu, kwaye usenokuyikrazula inyongo okanye uyitshise into efakwe kuyo. Ukukhetha okupholileyo kunye noxinzelelo lwesicelo kuba yinto ebalulekileyo. Ndikhumbula ibhetshi yemizimba yevalvu ukusuka ku-316 apho siye satsiba into yokupholisa yoxinzelelo oluphezulu ngesixhobo, sicinga ukuba isipholileyo sesikhukula sanele. Isiphumo? Umphetho owakhelwe phezulu kuyo yonke into efakiweyo, ukugqiba umhlaba owoyikekayo, kwaye iveki ilahlekelwe kukuphinda kusetyenzwe yonke into. Yayisisifundo sokuhlonela ubuntu bezinto eziphathekayo.
Emva koko unamabakala okuqina kwemvula afana ne-17-4 PH. Ukuyilungisa kwimeko yonyango (Imeko A) ilungile, kodwa ukuba inxalenye ifuna umatshini emva kokuguga ukuya kwi-H900 okanye i-H1150, usika intwasahlobo. Uxinzelelo lutshixiwe ngaphakathi, kwaye inxalenye inokuhamba ngokukhawuleza emva kokusikwa. Yento entsonkothileyo metal stainless machining inxalenye ngonyamezelo oluqinileyo, njengendlu yesivamvo se-aerospace, oku kuthetha ukuba kufuneka uphuhlise ulandelelwano: rhabaxa, ubudala, emva koko ugqibezele umatshini. Ngamanye amaxesha kuya kufuneka ushiye isitokhwe esongezelelweyo ukuze ufumane ipasi elicocekileyo lokucoca emva kokuguga ukuze ubethe ezo fowuni zokucaba okanye ukugxila. Asikokwenza iitshiphusi kuphela; ilawula yonke inkqubo metallurgical.
Apha kulapho ukusebenzisana ne-Foundry kunye nevenkile yomatshini efumana umjikelo opheleleyo wobomi ihlawula. Inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kunye namashumi amathathu eminyaka yabo kokubini ukuphosa kunye nokwenza, oku kubhakiwe kwinkqubo yabo. Abathathi nje ibhloko yesitokhwe sebha; basenokuba bephosa icandelo elikufutshane-netha-imilo kwi-cobalt alloy baze bayigqibe kwi-5-axis mill. Oko kudityaniswa kunyanzelisa ukuqonda kokuziphatha kwezinto ukusuka kwisinyithi esinyibilikisiweyo ukuya kwindawo yokugqibela, exabiseke kakhulu.
Umdaniso weZixhobo: Ngakumbi kunokuthenga nje olona Fakelo lugqwesileyo
Wonke umntu ufuna ukuthetha malunga ne-carbide egqunywe yamva nje okanye i-ceramic inserts. Ngokuqinisekileyo, zibalulekile. Kodwa ngenxa yomgangatho ophezulu metal stainless machining inxalenye, isixhobo sejometri sisiqingatha sedabi. Udinga i-engile ebukhali, efanelekileyo yehariki ukusika imathiriyeli kunokuba uyityhale, ukunciphisa amandla okusika kunye nobushushu. Kodwa elo cala libukhali libuthathaka. Lurhwebo oluqhubekayo. Ukugqiba, sinokusebenzisa i-wiper geometry efakwe ukufumana i-Ra 0.8 yesipili-njengesiphelo kwipasi enye, kodwa ukuseta kufuna ubungqongqo obupheleleyo kulungiselelo-nayiphi na incoko kwaye iyonakaliswa.
Ukugrumba imingxuma enzulu? Leyo yenye iphupha elibi. Ii-standard twist drills zinokupakisha kunye nezo chips ezinentambo kwaye zibethe ngokubetha kwentliziyo. Phantse usoloko udinga iparabolic flute drills okanye ngcono, isylid carbide coolant-through drills. Ixabiso ngesixhobo ngasinye liphezulu, kodwa ixabiso ngenxalenye elungileyo liyehla. Ndiyifunde le nto kabuhlungu xa kuqhutywa iibhloko ezininzi zehydraulic. Sizamile ukonga kwisixhobo sokusebenza nge-HSS-Co eqhelekileyo. Siye sadlula amacandelo amathathu phambi kokuba i-drill breakage yonakalise i-$500 engenanto. Ukutshintshela kwi-carbide drill efanelekileyo kunye ne-spindle coolant, kwaye siye saqhuba iindawo eziseleyo ze-50 ngaphandle komcimbi omnye. Ixabiso lesixhobo lithethelelwe kwiyure yokuqala.
Kwaye akuzona nje izixhobo zokusika isinyithi. Ukusebenza kubalulekile. I-stainless inokuba buthathaka kwimigangatho egqityiweyo. Ukusebenzisa i-serrated yentsimbi yemihlathi ngokuthe ngqo kwi-flange eyenziwe ngokuchanekileyo iya kushiya amanqaku. Utshintshela kwimihlathi ethambileyo ye-aluminiyam, uyimatshini kwindawo ukuze ubambe iprofayile yenxalenye, okanye usebenzise imihlathi yeplastiki engonakaliyo. Yongeza ixesha lokuseta, kodwa ayixoxiswana ngezinto zokuthambisa okanye zokutywina. Le ngqalelo kwiinkcukacha yahlula inxalenye esebenza kwinxalenye esebenza ngokugqibeleleyo kwaye ekhangeleka ngobuchule.
I-Precision Paradox: Ukunyamezelana vs. Inyani
Ukunyamezelana okuqinileyo kushicilelo sisithembiso, kodwa umatshini, isixhobo, imathiriyeli, kunye nobushushu obukhoyo buyinyani. Ukubamba i-±0.01mm kwifreyimu eyenziwe ngentsimbi eyi-500mm ende ayithethi malunga nokucwangcisa i-CNC ngokuchanekileyo. I-stainless ine-coefficient ebalulekileyo yokwandiswa kwe-thermal. Ukuba uqhuba umsebenzi onomthamo ophezulu kwaye ivenkile ifudumeza ngamaqondo ambalwa ukusuka kusasa ukuya emva kwemini, okanye ukuba iqondo lobushushu lokupholisa alilawulwa, imilinganiselo yakho iya kukhukuliseka. Kufuneka ubuyekeze, mhlawumbi ngolawulo lwenkqubo (ivenkile elawulwa yimozulu) okanye ngolandelelwano oluchuliweyo ukuvumela ubushushu buphele phakathi kwemisebenzi.
Kwinkampani efana ne-QSY, umsebenzi wayo usuka kwiiblayidi ze-injini yotyalo-mali ukuya kwii-welds ezinkulu zoomatshini, esi sisonka semihla ngemihla. Kuya kufuneka bathathele ingqalelo ukukhululeka koxinzelelo kwinkqubo yokuphosa ngaphambi kokuba baqale umatshini. Inxalenye inokubanjwa iye kwisiqingatha se-millimeter kwimeko yayo yokugqibela, kodwa ukuba ukujula okukrwada kunoxinzelelo lwangaphakathi, i-roughing cut yokuqala iya kuyikhulula kwaye inxalenye iya kujika njengetshiphu yetapile. Ngamanye amaxesha elona nyathelo libalulekileyo lomatshini linyathelo lokuqala lokuphelisa uxinzelelo. Linyathelo elingasusiyo nayiphi na imathiriyeli kodwa lenza onke amanyathelo alandelayo enzeke.
I-callouts yokugqiba umphezulu yenye indawo apho ithiyori idibana nokusebenza. Ungayicwangcisa i-stepover egqibeleleyo kunye nesantya sokutya, kodwa ukuba iibheringi zakho zokuphotha zinowona mdlalo uncinci, okanye ukuba isibambi sakho sesixhobo asilungelelaniswanga, uya kufumana ukungcangcazela okushiya iipateni ezibonakalayo. Ukufezekisa ukugqiba kwesipili esiyinyani, esingaguquguqukiyo kwipaneli enkulu yentsimbi etyiwayo kudla ngokufuna inyathelo lokugqibela lokupholisha ngesandla emva kokugaya i-CNC, obu bubugcisa ngokwayo. Kunqabile ukuba kube yinkqubo ezenzekelayo ngokupheleleyo ukusuka kwibhillet ukuya kwibhokisi.
Xa Izinto Zingahambi kakuhle: Izifundo zemfumba ye-Scrap
Ukungaphumeleli ngoyena titshala ubalaseleyo, ukuba nje uhoye. Kwangoko, ndandisenza uthotho lweeflange ezingama-304 ezingenasici. Ushicilelo lubize i-1/4 NPT yezibuko elinemisonto. Ndayicofa kwi-CNC, yabonakala ilungile. Emva kweveki, ingxelo yendibano igalelwe inkala kwaye ithinjwe. Kweneke ntoni? I-stainless, ngakumbi i-304, inomkhuba wokuba nenyongo xa iintsimbi ezifanayo zidityaniswe kunye phantsi koxinzelelo. Isisombululo ibingengomjikelo wokucofa ngcono; ibichaza isithambisi somsonto esahlukileyo sokudityaniswa okanye ukutshintshela kwisixhobo esifanelekileyo esahlukileyo njengobhedu lwendawo yokukhwelana. I-machining yayigqibelele, kodwa uyilo lokwenziwa kunye nokudibanisa kwakungaphelelanga.
Enye iklasikhi yi-corrosion. Wenza inxalenye enhle ukusuka kwi-316 engenasici, iphumelele uvavanyo lokutshiza ityuwa, kodwa umthengi ufowuna kwiinyanga ezintandathu kamva kunye namabala erusi. Ngokufuthi, kukungcoliseka kwentsimbi. Ukuba ubuchwetheza indawo engenanto kwilathe ebifudula isetyenziselwa intsimbi yekhabhoni, kwaye imihlathi yechuck okanye isixhobo asicocwanga ngobunono, amasuntswana amancinane entsimbi engenanto anokuthi afakwe kumphezulu ongenanto. La masuntswana anomhlwa, nto leyo ebangela ukuba inxalenye engenabala ibonakale ngathi iyasilela. Ukulungiswa kuyinkqubo: izixhobo ezizinikeleyo okanye iiprothokholi zokucoca ngokungqongqo zemisebenzi engenastainless. Ivakala ilula, kodwa kumgangatho wevenkile oxakekileyo, ayihoywa lula de ibize umxumi.
Ezi ayizongxaki zethiyori. Ziinkcukacha zegritty ezibonisa ukuba a metal stainless machining inxalenye uyaphumelela entsimini. Amava omthengisi adla ngokulinganiswa hayi ngoomatshini babo abatsha abengezelayo, kodwa ngoluhlu lwabo lweempazamo ezidlulileyo kunye neenkqubo abazakhileyo ukubathintela. Umsebenzi okudala umi njengalowo ungemva tsngtaocnc.com ngokungaphephekiyo unobu nzulu, emva kokuba ujikeleze yonke into ukusuka ekulahlekeni ukuya kwinxalenye yokugqibela ye-corrosion iminyaka engaphezu kwama-30.
Owona Mfanekiso Mkhulu: Ukusuka kwiNdawo ukuya kwiCandelo eliDityanisiweyo
Okokugqibela, kufanelekile ukukhumbula ukuba indawo yomatshini ayifane ibekho yodwa. Licandelo kwinkqubo. Apha kulapho ukuphoswa okudityanisiweyo kunye nesakhono somatshini siba yinzuzo enkulu. Thatha indlu yempompo. Ungayimatshini ngokupheleleyo ukusuka kwibhloko eqinileyo ye-316, kodwa uchitha i-70% yemathiriyeli njengeetshiphusi, kwaye ixesha lomatshini likhulu. Kungenjalo, ungenza ukuba utyalo-mali luphoswe yingcaphephe efana ne-QSY ukuya kwimilo ekufutshane nenetha, eneendawo zokutywina ezibalulekileyo, imingxuma yebholiti, kunye namazibuko afuna ukwenziwa ngomatshini. Ixesha elikhokelayo linokuba lide ngenxa yenkqubo yepateni yokuphosa, kodwa ukusetyenziswa kwezinto eziphathekayo kubhetele, inxalenye ihlala inokwakheka okuziinkozo okuphezulu, kwaye ixabiso lokugqibela lemiqulu ephakathi ukuya phezulu iphantsi.
Le ndlela ifuna intsebenziswano enzulu phakathi kwenjineli yoyilo kunye nomvelisi kwasekuqaleni. Ngaba i-engile eyidrafti inokudityaniswa ekusalweni ukuze kube lula ukukhululwa kokungunda? Ngaba singakwazi ukuyila inkqubo yedatha ekhoyo ekusalweni kwaye isetyenziswe kubo bonke oomatshini? Injongo kukuyila yonke inkqubo yokuvelisa, kungekhona nje ijometri yokugqibela. Ezona projekthi zonelisayo kuxa siziswe kwisigaba sokulinganisa, kwaye sinokuthi, Ukuba ulungisa olu didi lodonga kwaye wongeze iradiyasi apha, singayiphosa ngokuthembekileyo kwaye sinciphise ixesha lomatshini ngama-30%. Kulapho usuka ekubeni yivenkile yoomatshini uye ekubeni liqabane lemveliso.
Ngoko ke, xa ukhangela i metal stainless machining inxalenye, awuthengi nje ixesha kumatshini we-CNC. Uthenga ukuqonda kwe-metallurgy, izixhobo zokusebenza, iziphumo ze-thermal, kunye nokudibanisa inkqubo. Inxalenye efika kwi-dock yakho sisiphumo somzimba wekhulu lezigqibo ezincinci, izilungiso, kunye namaqhekeza amava aphumelele nzima. Ukukhanya linyathelo lokugqibela.
