Kana mumwe munhu achinyora 'precision machining padhuze neni' mubhawa yekutsvaga, ndinowanzo shamisika kuti chii chaizvo chavari kutsvagira. Ingori geography here, kana kuti kudiwa kwakadzama kwechitoro chavanogona kutyaira, kutarisa foromani mumaziso, uye kukurukura nezveburr pane titanium actuator imba? Mutsara wacho pachawo wakapfava zvinonyengera. Iyo inounganidza yakakwira-tarisiro maitiro neiyo yakakosha locator, uye ndipo panowanzo rara kusanzwisisa kwekutanga. Kuva pedyo hakuvimbisi kugona. Ndakaona vatengi vachipiswa vachisarudza chitoro chiri pedyo, vongoona kuti havagone kubata basa rechokwadi re5-axis panguva imwe chete kana kushaya metrology yekushivirira kwatiri kutaura nezvayo-funga ± 0.0005 pane yakaoma contour, kwete kungochera mamwe maburi mundiro.
Beyond the Zip Code: Kutsanangura Precision muMatemu Chaiyo
Ngatiparadze 'precision machining' kubva mukati. Harisi izwi rekutengesa ratinokanda kose. Munyika yedu Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), inotanga nestock. Iwe haugone kudhiza machina kuita yekukanda kwakashata. Ndosaka makore edu matatu emugoko uye kuisa mari pakudyara asiri bhizinesi rakasiyana; ndivo danho rekutanga. Kana iyo yepedyo-neti-chimiro kubva kune yakawanikwa iine shrinkage yemukati kana isingaenderane madziro ukobvu, chirongwa cheCNC chiri kurwisa hondo yekurasikirwa kubva pakubata chishandiso chekutanga. Saka kana mutengi achitiunzira kudhindwa kwepombi yemugungwa mune duplex tsvina, pfungwa yangu yekutanga hausi muchina. Iko kana maitiro edu ekukanda anogona kuendesa isina chinhu inopa iyo machining side mukana wakanaka wekurova iwo anoyerera chiteshi chepamusoro chinopera.
Rondedzero yezvinyorwa inotaura nyaya. Kanda simbi, simbi, isina tsvina-chokwadi. Asi kana iyo spec inoda cobalt-based kana nickel-based alloys, mutambo unoshanduka. Pedyo neni inoita kunge isingaite kana shopu isinganzwisise kuomarara kwekushanda, isina zvigayo zveceramic yekupedzisira, kana isingakwanise kubata kupisa. Ndinorangarira basa re turbine seal component muInconel 718. Mumwe mukwikwidzi weko akazvitora zvichienderana nenzvimbo. Vakapisa nemidziyo, vakaunza kushushikana kwakasara, uye zvikamu zvakamonyoroka mushure mekugadzira. Mutengi akapedzisira atumira mabheji anogona kuponeswa kwatiri zvakadaro. Chinhambwe chakavadyira batch yezvinhu zvinodhura uye mavhiki ekunonoka.
Saka zano rangu? Shandisa padyo neni kutsvaga vangango shanda navo, asi vavheneke nechidimbu chebvunzo. Bvunza nezve maitiro avo ekutonga kwechinhu chakareruka asi chinotaurira: gomba rakadzika, diki-dhayamita mu304 isina tsvina. Vanogona here kubata kutwasuka uye kupedza pamusoro pehupamhi 10x dhayamita? Mhinduro yavo-uye muenzaniso-inokuudza zvakawanda kupfuura pini yenzvimbo yavo pamepu.
Iyo Yekubatanidza Edge: Kana Kukandira uye CNC iri pasi pedenga rimwechete
Apa ndipo pane iyo modhi yemugadziri akanyatsobatanidzwa akafanana QSY inoshandura calculus. Mukana wakakura hausi wekungoita zvinhu chete, kunyangwe kuve newakavakirwa uye muchina chitoro mazana mashoma emamita akaparadzana kunocheka nguva yekutungamira zvakanyanya. Zviri pamusoro pemhinduro uye kuzvidavirira. Iyo machinist inosangana nenzvimbo yakaoma mukukanda inogona kufamba kuenda kune foundry maneja uye inonongedza. The foundry timu inogona kugadzirisa gating kana kutonhora maitiro einotevera batch zvichibva pane chaiyo machining data, kwete chete theoretical specs.
Isu takanga tine purojekiti yeakatevedzana miviri yevharuvhu muCF8M isina tsvina. Mutengi aida ASME B16.34 kuteedzera, izvo zvaireva kuomarara NDE pane yekukanda uye kushivirira kwakasimba pazviso zveflange uye kubereka. Nekuti ese ari maviri maitirwo aive mumba, taigona muchina chinyorwa chekutanga, kuita bvunzo yekumanikidza, kutsvaga micro-porosity nyaya pakona-inoshushikana, tozogadzirisa dhizaini yekukanda mhepo. Kudzokororwa kwacho kwakatora mazuva, kwete mavhiki. Mutengi ari kutsvaga precision machining pedyo neni inogona kusatanga kufunga nezve yekutanga link, asi kune yakaoma zvikamu, kazhinji mutsauko pakati peiyo prototype inoshanda uye inongori inodhura modhi.
Zvakaipa? Zvinoda bhenji rakadzika remainjiniya akadzidziswa. Vedu machining programmers vanofanirwa kunzwisisa kusimba shrinkage. Inyanzvi yehunyanzvi isingabvi kuchitoro chebasa padhuze neni inongogadzira machining kubva kutengwa-mubar stock.
Kushandisa, Kugadzirisa, uye Maawa Asingaoneki
Chero ani zvake anogona kutenga yechimanjemanje CNC muchina. Hunyanzvi chaihwo-uye mutengo wakavanzika-uri mukubata uye nzira yekushandisa nzira. Kune batch yedzimba dzepombi, tinogona kupedza maawa makumi mana tichigadzira uye tichivaka tsika yakawanda-yezviteshi zviteshi zvinotibvumira kuchina makumi masere muzana ezvimiro mune imwe setup. Ndiyo maawa makumi mana enguva isiri-machining chirungiso chisati chatombotendeuka. Chitoro chinokwikwidza pamutengo wemunharaunda uye wakaderera chinogona kusvetuka izvi, uchishandisa vise uye nhanho zvidhinha, kuunza akawanda setups uye kukanganisa kukanganisa. Chikamu chinogona kuitwa, asi hachizove chakanyatsojeka.
Zvadaro pane software. High-speed machining nzira dzealloys, trochoidal milling kuderedza turusi mutoro-apa ndipo panobhadhara ruzivo rwemugadziri. Haimo mubhuku rekushandisa. Takadzidza izvi kuburikidza nematurusi akatyoka uye zvidimbu zvakaraswa kare kare. Ikozvino, kune chinhu chitsva senge proprietary nickel alloy, isu ticharamba tichiita chibayiro bvunzo kumhanya, kufona mumafeed uye nekumhanyisa neruoko pakutonga, kutarisa chip ruvara uye kuteerera kune yakatemwa. Ndiwo maitiro ausingakwanise kupa kunze kana kuwana nekutsvaga kwenzvimbo kuri nyore.
Iyo Metrology Reality Check
Precision inotsanangurwa nechiyero, kwete chinangwa. Chitoro chinogona kutora ± 0.001 kugona, asi vari kuyera nei? A handheld micrometer yakanaka kune shaft dhayamita, asi haina basa kune yechokwadi chinzvimbo chegumi nemaviri maburi maburi paPCD kana chimiro cheakakomberedzwa akawanda. Yedu CMM kamuri yakakosha seyedu DMG Mori 5-axis. Uye kunyange zvakadaro, kutonga kwezvakatipoteredza kunokosha. Isu tinoyera zvakakosha zvikamu zvendege mangwanani, mushure mekunge lab yave tembiricha-yakagadzikana husiku. Kana wako wepanzvimbo chaiyo machining shamwari achiyera zvikamu pauriri hwechitoro padyo nemusuwo wakavhurika muzhizha, data iri kufungidzira.
Ndinoyeuka kukundikana kwakandirwadza. Isu takagadzira seti yekuisa jekiseni mold kubva kuH13 chishandiso simbi. Vakayera zvakakwana paCMM pa20°C. Mutengi akaaisa mumold base yaimhanya pa90°C. Kusiyana kwekuwedzera kwekushisa kwakakonzera kukanganisa. Isu takanga tisina kufunga nezve tembiricha yekushandisa mune yedu yekushivirira stack-up. Ikozvino, kune chero chishandiso kana chakakwira-temp chikamu, iyo hurukuro chikamu chewongororo yekutanga. Icho chidzidzo chaicho, chinorwadza chakagadzirisa rondedzero yedu yeDFM.
Kuita Pedyo Neni Kukushandire
Saka, kana iwe uchitsvaga precision machining masevhisi, shandisa geographic filter, asi wozochera zvakadzika. Tarisa humbowo hwekugadzira yakabatanidzwa kana chikamu chako chikatanga sechikandira kana kuforoma. Ongorora nhoroondo yavo yezvinyorwa-kumbira zvidzidzo zvenyaya pane chaiyo alloy yaunoda. Kumbira kushanyirwa. Chitoro chakachena, chakarongeka chine michina yechizvino-zvino, inochengetedzwa zvakanaka uye yakazvipira mhando lab chiratidzo chakanaka. Bvunza nezve CMM yavo yakakura, kurongeka kwayo kwevhoriyamu, uye kuti kangani yakagadziriswa.
Kune kambani yakaita seyedu, QSY, nhoroondo yemakore makumi matatu haisi nhamba chete. Zvinoreva kuti takagadzira zviuru zvezvikamu zvakasiyana, kubva kumabhuranzi akareruka kusvika kune zvinobatika zvinhu, uye isu takavaka ruzivo rwemasangano rwezvinogona kukanganisa. Chiitiko ichocho chinobikwa muhurongwa hwekuronga. Izvo zviri padyo neni zvevatengi vedu zvinowanzo shandura kune kushandira pamwe kuri nyore-vanogona kushanya, kuona zvikamu zvavo mukuita, uye kutarisana nekutarisana kweinjiniya. Hukoshi ihwohwo husingabatike kazhinji hunokurira musiyano wemutengo mudiki pachikamu kubva kune ari kure, asingazivikanwe mutengesi.
Pakupedzisira, chaiyo chaiyo machining mubatanidzwa, kwete kutengeserana. Kutsvaga kunofanira kunge kuri kwemudiwa anokwanisa anogara achienderana nenzvimbo, kwete neimwe nzira. Chitoro chekurudyi chinobvunza mibvunzo yakawanda sezvaunoita, nekuti ivo vanoziva kuti mukurumbira wavo unogadzirwa muchikamu chese chavanotumira.
