Iyo wunvise 'high precision machining', ikintu cya mbere kigaragara mumitwe yabantu benshi numubare. Turashobora kwihanganira ± 0.001 santimetero cyangwa Imashini zacu zirashoboye sub-micron neza. Nicyo kiganiro cyiza cyane. Inkuru nyayo, iyingenzi mububiko, itangira umaze kugura miriyoni y'amadorari atanu-axis Imashini ya CNC Hagati. Nibwo wiga neza ntabwo ari urupapuro rwimashini gusa; ni urunigi. Urunigi rwo kugenzura ubushyuhe, kwambara ibikoresho, gukomera, imyitwarire yibintu, kandi, mvugishije ukuri, intuition. Amaduka menshi, cyane cyane asimbuka ava muri rusange akajya mubikorwa 'bihanitse cyane', arabura. Batekereza ko imashini ikora imirimo yose. Iyo ni inzira yihuse yo gusakara bihenze.
Urufatiro: Ntabwo ari CNC gusa
Nabibonye inshuro nyinshi. Amaduka abona ikigo gishya, cyohejuru-cyogukora imashini, akubita inshyi 304 kumeza kumeza, kandi yiteze ko indorerwamo zirangira na bores nziza. Noneho bahamagare kubyerekeye ibibazo byo kunyeganyega cyangwa gutwarwa nubushyuhe. Ikibazo cya mbere mbajije ubu ntabwo kijyanye nibiryo byabo n'umuvuduko wabo; bijyanye n'ishingiro ryabo. Mubisanzwe. Igorofa ni icyapa cya monolithic gitandukanijwe nizindi ngendo z’ibimera? Kurwego rwakazi dukora mukigo cyacu, nka geometrike igoye kubice bya valve biva mu mavuta adasanzwe, ndetse na forklift itwara metero 50 uvuye kure irashobora gutangiza umutingito ugaragara nkikimenyetso cya 0.0002. Ntushobora guteganya ibyo hanze.
Noneho hari ikirere. Kwiruka a gutunganya neza selile ni nko gukora laboratoire ya metero. Tugumana ibidukikije bigenzurwa, ± 2 ° F niba dushobora kubufasha. Aluminium nicyuma byaguka kandi bigasezerana kurenza uko wabitekereza kumunsi. Niba utangiye akazi mugitondo iyo ari 68 ° F ukarangiza urugero rukomeye saa sita iyo ari 74 ° F hafi yidirishya, wabuze neza. Kubushoramari bwa casting prototypes ikeneye gutunganywa bwa nyuma, ibi ntibishobora kuganirwaho. Igice kimaze kunyura mu gishashara, igikonoshwa, no gusuka inzira; kuyishakisha mu cyiciro cya nyuma cya CNC kubera ubushyuhe ni igifu.
N'ibikoresho. Aha niho ibyiyumvo byinjira. Urashobora kugira spindle nziza yakozwe nu Busuwisi, ariko niba ukoresha urusyo rusanzwe ruvuye mu binini byinshi, ibagirwe. Dutanga ibikoresho byihariye, bifunze ibikoresho bitandukanye. Gukora nikel ishingiye kuri nikel nka Inconel ninyamaswa zitandukanye ugereranije nicyuma cya karubone. Igikoresho cya geometrie, igifuniko (AlTiN na TiAlN), kubara imyironge - byose bifite akamaro ko gukwirakwiza ubushyuhe no kwimura chip. Igikoresho cyambarwa ntigitanga gusa kurangiza nabi; ikoresha ubushyuhe bwinshi nigitutu, ikarwanya igice microscopically. Urashobora gukomeza kwihanganira, ariko imihangayiko isigaye izakuruma nyuma mugihe cyo guterana. Twabyize inzira igoye kumurongo wubuvuzi bwa cobalt-chrome.
Kwibuka Ibikoresho n'imbyino zo Kumashini
Nibintu bitandukanya abakora igice naba injeniyeri basobanutse. Ibikoresho bifite kwibuka. Castings, umutsima n'amavuta muri Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), ni urugero rwiza. Igikonoshwa cyo gushushanya cyangwa gushora imari biza mu ishami rya CNC hamwe nibisanzwe, bifunze-biturutse ku gukonjesha. Niba uyihagaritse gusa hanyuma ugatangira guhisha ibintu bikabije, urekura iyo mihangayiko idahwanye. Igice kizimuka, rimwe na rimwe gitangaje, iburyo kumeza.
Inzira twateje imbere, nyuma yitsinda ryatsinzwe hakiri kare, ni imbyino ya pasiporo yumucyo hamwe nuburyo bukurikirana. Turashobora gufata casting, gukora op igoye kugirango tuyinjire muri 0.050, hanyuma tuyifungure, ihangayikishe mu ziko, hanyuma twongere tuyihuze kugirango irangize. Gusa nyuma yibyo tujya kumukino wanyuma, gutunganya neza pass. Yongera intambwe, yongeraho igihe, ariko niyo nzira yonyine yo kwemeza ituze. Ibi birakenewe cyane cyane kubice bikikijwe n'inkuta zisanzwe mubice byo mu kirere rimwe na rimwe dukora. Ikosa rya kera ni ukwirukana gutungana muburyo bumwe; rimwe na rimwe, ugomba kureka igice kigatangira ibikorwa.
Ibikoresho ni ibihangano byayo. Kubintu bigoye, asimmetrical ishoramari-igice, gushushanya urwego rutanga inkunga itajenjetse rutarinze kugoreka ibintu ni urujijo. Dukunze gukoresha sisitemu ya modular hamwe na jasse yoroshye ikozwe mumwanya-bivuze ko dukora imashini yumusaya kumashini imwe izakora igice, ikemeza guhuza neza. Nigihe cyo gushora imari imbere yishura umusaruro wose. Ndibuka umushinga wamazu ya pompe yo mumazi muri duplex ibyuma bidafite ibyuma aho igishushanyo mbonera cyambere cyateje umuheto 0.0015. Byagaragaye gusa kuri CMM nyuma yukuri. Twongeye gushushanya kugirango dushyigikire imbere mugihe cyo gutunganya, cyakemutse. Igishushanyo mbonera nticyigeze kibivuga; uburambe bwakoze.
Ibipimo bya Metrology
Ntushobora kugenzura ibyo udashobora gupima, ariko kandi ntushobora kureka ibipimo bikaguhagarika umutima. Intego ntabwo ari ugupima buri kintu cyose kuri buri gice - ibyo ntibiramba. Intego ni ugushiraho ibitekerezo byizewe hagati yimashini nigikoresho cyo gupima. Scaneri yacu ya CMM na laser ntabwo igenzurwa gusa; ni ibikoresho byiterambere.
Mugihe tubonye umuryango mushya, vuga urukurikirane rushya rwimibiri idafite ibyuma byumukiriya, tuzakora ingingo yambere yingingo zikoreshwa cyane. Imashini ibice bitanu. Nyuma ya buri gikorwa gikomeye, bapime. Ntabwo ari ibipimo bikomeye gusa, ahubwo ushakishe no gushushanya - ibice byose bigenda muri Z-axis kubwinshi? Haba hari icyuma muri bore cyerekana gutandukanya ibikoresho? Ayo makuru asubira inyuma kuri programu ya CNC. Turashobora guhindura igikoresho cyo guhagarika, guhindura gahunda y'ibikorwa, cyangwa kongeramo isoko. Uyu muzingo uhindura imashini kuva impumyi ikora sisitemu yo kwiga. Uwiteka Imashini ya CNC inzira iba ihamye kandi iteganijwe.
Ariko hano hari umutego: kwishingikiriza cyane kubisomwa bya digitale. Rimwe na rimwe, ibyiyumvo bifite akamaro. Umukanishi w'inararibonye ukora pass yo kurangiza kuri titanium alloy arashobora kumva itandukaniro riri hagati yo gukata neza nimwe itangiye kuganira. Arashobora kubona ibara rya chip. Ibyo bitekerezo byubusa birahita. Gutegereza raporo ya CMM nyuma yamasaha abiri biratinze. Turinganiza rero. Imashini ikora imashini ifite micrometero ya Calibrated na bore gage kuri sitasiyo ye kugirango igenzurwe mubikorwa byingenzi. Nibwo buvange bwibisobanuro bya digitale hamwe na analog intuition ituma ubuziranenge buba hejuru kandi bukava hasi.
Iyo Precision ihuye n'inzira z'umurage
Amateka yisosiyete yacu, imyaka irenga 30 mugukina no gutunganya, itanga ikibazo cyihariye ninyungu. Ikibazo ni uguhuza ibigezweho gutunganya neza ibiteganijwe hamwe nuburyo bwo gushinga umurage. Gutera ishoramari birashobora kuba byiza, ariko isura ya datum ntishobora kuba ikwiranye neza na CNC vacuum chuck. Tugomba gukora inyuma rimwe na rimwe, tugafatanya nitsinda ryacu ryashinzwe kugirango duhindure igishushanyo cya casting gato - twongereho ibikoresho bito, gusibanganya ubuso buhagije kugirango bifatanye - kugirango bikorwe kwihanganira kijyambere. Nibiganiro byimbere hagati yubuhanzi bwo gukina na siyanse yo gutunganya.
Akarusho, ariko, ni ubumenyi bwimbitse. Iyo umukiriya atwoherereje igishushanyo cyigice muri Monel cyangwa Hastelloy, ntabwo tuba dusoma urupapuro rwihariye. Uruganda rwacu rumaze imyaka mirongo rusuka ayo mavuta adasanzwe. Twese tuzi uko bitwara mugihe cyo gukomera, aho ubwoba bushobora kwihisha, uko bitwara ubushyuhe. Ibi biramenyesha ingamba zacu zo gutunganya ako kanya. Turabizi Hastelloy akazi-gakomeye nkumusazi, nuko tuzateganya ibikoresho bikarishye, guhora dusezerana, kandi ntituzigera tureka igikoresho. Ubwo bushishozi ntabwo buri mubitabo bisanzwe byo gutunganya; ni kwibuka. Bitwemerera gusubiramo no gukora imirimo igoye iduka ryimashini rishobora kwanga.
Ubu busabane nicyo dukoresha kuri QSY. Umukiriya arashobora kuzana igitekerezo, kandi turashobora kukuyobora binyuze muguhitamo ibikoresho (kuva kumyuma kugeza kuri nikel ishingiye kuri nikel), muburyo bukwiye bwo guterana (shell mold for runini runini, ishoramari kumiterere igoye), hanyuma amaherezo tunyuze a Imashini ya CNC inzira yagenewe ibyo bikoresho byihariye na geometrie. Ibisobanuro ntabwo ari ibitekerezo; cyashizwe mumurongo wo gukora kuva mugitangira. Nibisobanuro nyabyo byo gutunganya neza murwego rwo guhuza ibikorwa. Ntabwo ari ishami; ni filozofiya itangirira kumurongo wambere kugeza deburring ya nyuma.
Igiciro Cyukuri Cyukuri
Hanyuma, ukuri kutabeshya. Ibisobanuro bihanitse bihenze, kandi bigomba kuba. Birahenze mumigabane (imashini, kugenzura ikirere, metrologiya), mubikoreshwa (ibikoresho byabigenewe, gukonjesha ubuziranenge), kandi cyane cyane, mugihe n'ubuhanga. Igihe cyizunguruka kubice byuzuye ni kirekire. Hano haribindi byinshi, kugenzura byinshi, kugaburira buhoro no kwihuta kugirango ubungabunge ubusugire nuburinganire buringaniye.
Twabonye anketi igihe cyose umuguzi ashaka kwihanganira urwego rwindege kubiciro byibicuruzwa. Ntabwo bihuye. Urubuga rwacu, tsingtaocnc.com, rugaragaza neza ubushobozi bwacu, ariko ikiganiro gikurikira kijyanye n'uburere. Turasobanura impamvu gufata umwanya wukuri 0.0002 kumurongo itatu uhuza ibice 17-4 PH bidafite ibyuma bisaba intambwe yihariye, bityo rero, ikiguzi cyihariye. Rimwe na rimwe, tunagira inama umukiriya kuruhura kwihanganira niba bidakomeye - birashobora kuzigama 30% kubiciro byigice. Kuba umufatanyabikorwa bisobanura rimwe na rimwe kubabwira ibyo badakeneye, byubaka ikizere kuruta gusezeranya ibidashoboka.
Mu kurangiza, gutunganya neza neza ni kwiyemeza. Nukwiyemeza kugenzura impinduka abandi bose birengagiza, gushora mubumenyi nko mubikoresho byuma, no kumva ko umubare wuzuye kuri ecran ari ibisubizo byibyemezo ijana bidatunganye, byabantu byafatiwe mububiko. Ni akajagari, itera, kandi iranyuze cyane iyo byose bishyize hamwe. Nibyo rwose urimo kwishyura.
