Kana vanhu vazhinji vakanzwa 'precision screw machining', vanobva vangoona maSwiss-type lathes achiburitsa zvidimbu zvidiki, zvakaomarara. Izvo hazvina kukanganisa, asi maonero epamusoro-soro. Dambudziko chairo, iro chikamu chinopatsanura zvitoro, harisi rekubata kushivirira kwakasimba - ndezvekutonga hupenyu hwese hwechikamu, kubva pahunhu hwenyama kusvika kune post-machining zvinonetsa, kunyanya kana uchinge uchitarisana nezvinhu zvakaomarara senge nickel-based alloys. Ndakaona dhizaini yakawandisa ichiuya inotaura kushivirira kwakasimba kupfuura zvakafanira, kukwidza mutengo pasina bhenefiti. Iyo chaiyo iri mukuronga, kwete kungocheka chete.
Nyaya ndiyo Yekutanga Blueprint
Iwe haugone kutaura nezve chaiyo basa usina kutanga nestock. Apa ndipo panokundikana fungidziro dzakawanda. Kambani yakadai Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nemakumi matatu emakore ekugadzira uye kugadzira, vanowana izvi nemasikirwo. Havangogamuchire mabheti chete; kazhinji vanotanga nekukandira kwavo vamene. Iyo homogeneity, iyo yemukati yekushushikana mamiriro kubva kune goko mold kana investimendi yekukanda maitiro-iyo inoisa nhanho yezvese zvinouya mushure. Kana iyo base zvinhu iine kusawirirana, yako machining maitiro ari kungozvinyora, kwete kugadzira chaiyo.
Kushanda neakakosha alloys, taura kune yakakwirira-tembiricha aerospace fastener, inoshandura mutambo zvachose. Cobalt-based alloys inoshanda-yakaoma nekukurumidza. Nzira yako yekushandisa, chikafu, uye kumhanya inova nhaurirano nezvinhu, kwete murairo. Chirongwa chechokwadi chisingaverengere izvi chinoburitsa chikamu chine mativi akanaka chizere nediki-diki kana chine basa-rakaomeswa pamusoro pedhiri rinotadza kushanda. Kushivirira pane zvakadhindwa kunogona kunge kuri ± 0.0005, asi iyo chaiyo fungidziro ndeyekutendeseka kwechimiro chezviyo.
Ndinoyeuka purojekiti yehunde yevharuvhu yekudzora mvura. Kudhinda kwakadaidzira 316 isina tsvina, asi iyo application yaisanganisira cyclic stress. Isu takakurudzira shanduko kune vacuum-yakanyunguduka musiyano ine zvidzoreso zvakasimba pane zvinosanganisirwa. Mutengo wega wega usina chinhu wakakwira, asi kudzikiswa kwekupfeka kwezvishandiso uye kubviswa kwekutadza kweashoma panguva yekuedzwa kwehumbowo kwakachengetedza hukuru. The precision screw machining yakanga yakafanana pabepa, asi mhedzisiro yacho yakanga yakasiyana nekuti zvinhu zvacho zvaibatwa sechinhu chinoshanduka, kwete chinogara chiripo.
Iko Kukandira Kunosangana neMachining: Iyo Yakakosha Handoff
Iyi ndiyo yakavanzika sosi ye vertical integrated mashandiro. Panzvimbo inoita zvese zviri zviviri, seQSY, timu yekugadzira haisi kushanda kupokana nekukandwa kusingazivikanwe. Vane nhoroondo nazvo. Ivo vanoziva shrinkage mvumo inoshandiswa, yakajairika gedhi nzvimbo, mukana wezvishoma porosity nzvimbo mune mamwe majeometri. Izvi hazvina kunyorwa kune chero mufambi; ruzivo rwedzinza.
Kune yakaomesesa yekudyara-yakakandwa imba inoda chaiyo tambo madoko, machinist anoziva kuti ndeapi madhamu anovimbika zvakanyanya kubva mukukanda. Vanogona kusiya imwe hafu yemamirimita pamadziro chaiwo, kwete nekuti kudhindwa kunoda, asi nekuti vanoziva kuti madziro mune iyo alloy anowanzo kanganisa zvishoma panguva yekupisa, uye vanozorova yekupedzisira mushure meiyo nhanho. Izvi ndizvo precision screw machining kufunga mumativi mana, kuwedzera nguva uye kutevedzana kwemaitiro muchikamu chekushivirira.
Iyo handoff yekutadza modhi yandakaona ndeye kana machining ari siloed. Vanowana casting, voisunga, votanga kucheka. Kana iyo yekukanda iine uta hudiki kubva kune yakasara kunetseka, ivo vanoigadzira yakatwasuka ... chete kuti iite kuti idzoke shure mushure mekunge ma clamps aburitswa. Icho chikamu chave chirahwe, asi chakayera zvakakwana paCMM ichigadziriswa. Kubatanidzwa kunodzivirira izvi. Iyo machining chirongwa chikamu chekukanda dhizaini ongororo.
Tooling Philosophy: Kwete Nezve Turusi
Taura kune chero machinist, uye ivo vanozobuda pane zvishandiso geometries uye machira. Izvo zvakakosha. Asi huzivi kuseri kwetooling zano ndiko kunotsanangura kugona kwechitoro. Yepamusoro-chaiyo, diki-batch basa pane alloys, ndezvekufungidzira, kwete kungoita peak performance.
Isu takamira pane chaiyo mhando yemicro-grain carbide inoisa yekupedzisa ops pasimbi alloys. Kwete nekuti ivo vaive vakaomesesa zvakanyanya, asi nekuti yavo yekupfeka curve yaive mutsara uye inofanotaurwa. Tinogona kumhanyisa zvikamu zana, kuyera maturusi ezvishandiso, uye nekufanotaura zvakavimbika nguva yekuchinja inoisa pamberi pekushivirira kudonha. Izvi zvinofinha, zvisingaite. Iyo haina kuhwina kumhanya mibairo, asi inobvisa zvimedu zvimedu. Iwe unogona kuwana iyi pragmatic nzira yakatsanangurwa mune tekinoroji zviwanikwa pane saiti senge tsngtaocnc.com, uko kutariswa kuri pakuvimbika kwemaitiro ezvikamu zvakakosha.
Inotonhorera haisi mafuta chete; igadziriro yekutarisira kupisa. Paunenge wakabata chegumi pane screwless screw, kupisa kwekucheka kunoda kukweverwa kure nguva dzose. A 5-degree Celsius swing mune imwe tembiricha inogona kuridza kushivirira kwako. Taive nebasa apo zvikamu zvakayerwa mu-spec pamushini asi zvakatadza QA yekupedzisira. Nyaya yacho? Imba yeCMM yaitonhorera madhigirii gumi. Maparts akanga abatana. Iyo chaiyo yakarasika kune basic fizikisi. Ikozvino, kuenzana kwemafuta chikamu chechekutanga-chinyorwa chekutarisa.
The Fixturing Fallacy
Wese munhu anoziva zvakakosha kugadzirisa zvakanaka. The fallacy iri kufunga zvakaoma, tsika zvigadziriso ndiyo nguva dzose mhinduro. Chokwadi precision screw machining, kunyanya pane legacy multi-spindle automatics kana Swiss lathes, dzimwe nguva yakanyanya kunaka mhinduro ndeye yakagadziridzwa yakajairwa collet kana yakanyatsoiswa mhenyu centre.
Ndakadzidza izvi nenzira yakaoma. Yakagadzirwa yakanaka, yakatsaurirwa gadziriso yemhuri yendarira yekubatanidza zvikamu. Yaibata matanhatu panguva, yakagadzira zvese maficha mune imwe op. Muchirevo, zvakakwana. Mukuita, chero chidiki diki chakamisikidzwa mumuviri wekugadzirisa chaizorereka chikamu zvishoma, chichikwenya batch rese. Takapedza nguva yakawanda tichichenesa uye tichiona gadziriso pane kumhanya zvikamu. Ndakadzokera kune yakapfava, imwechete-chikamu collet workholding. Nguva yekutenderera pachikamu chaive chakareba, asi kubuditsa kwese uye goho zvakakwira. Precision kazhinji ndeye kudzikisa zvinoshanduka, kwete kuwedzera kuoma.
Kwenguva refu, yakatetepa screws - funga lead screws kana actuator shafts - gadziriso ndiyo maitiro ese. Uri kurwisa kutsauka. The trick haisi nguva dzose kuzorora kwakadzikama. Dzimwe nguva kutevedzana kwemaitiro: tendeuka, kushushikana kudzikamisa, wozopedzisa kutendeuka. Iwe unochina chikamu kaviri kuti chiite kuti chiwane chimiro chayo pakati. Nguva yemuchina inopetwa kaviri, asi chikamu chinoshanda. Ndiyo ongororo yemutengo-bhenefiti yausingazoiwana mubhuku.
Kuyera inhanho, kwete nhanho
Kuongorora kwekupedzisira hakusi kutonga kwemhando; iongororo. Hunhu chaihwo hunovakwa mukuita. Zvemascrew machining, izvi zvinoreva mu-kuita gauging, SPC yekuunganidza data pane dzakakomba zviyero, uye-zvikuru-kunzwisisa zvauri kuyera.
Chinhu chakaiswa shinda yekurapa chinogona kunge chine dhayamita yakakura uye kukwirira. Asi kana midzi yeshinda ine microscopic radius kubva kune yakasakara chishandiso, inova inokonzeresa kunetseka. A standard thread plug gauge inoipfuudza. A optical comparator kana profilometer inogona kuibata. Tsananguro yechokwadi yechikamu ichocho inosanganisira yekupedzisa kwepamusoro mumudzi. Unofanira kuyera chinhu chakanaka.
Isu takabatanidza iri nyore laser micrometer pane yekudyisa stock yeyakakwira-vhoriyamu pini basa. Yakanga isiri yekuronga; yaive yekutarisisa. Kuona dhayamita yeinouya bhaa stock drift nemamicrons akatibvumira kuti tigadzirise maturusi maturusi maturusi asati abuda kunze. Aya ndiwo mafungiro: kuyerwa seyemhinduro loop yemuchina, kwete kungopfuura / kutadza gedhi kumagumo. Inofambirana neyakadzama nzira yaunoona kubva kune vakamisikidzwa vatengesi vanobata yakazara cheni, kubva pakusarudza alloy kusvika yekupedzisira metrology.
Kuchidzosa Zvese kuFloor
Saka izvi zvinotisiya kupi? Precision screw machining harisi dhipatimendi; itsika. Ndiye munhu wenyama ari kutaura neboka rekukanda, anotaura nemugadziri wepurogiramu, anoteerera kune machinist ari kuita basa, anodyisa data kumusana weinjiniya. Ndezvekuita sarudzo uine hurongwa hwese.
Paunotarisa kugona kwekambani, seyakatsanangurwa QSY, kiyi haisi iyo rondedzero yemichina. Inyaya yekuti vanga vachikandira uye kugadzira pasi pedenga rimwechete kwemakore anopfuura makumi matatu. Hupenyu hurefu ihwohwo hunoratidza kuti vakagadzirisa matambudziko aya ekubatanidza. Ivo vanogona kunge vakadzidza, kuburikidza nekuyedza uye kukanganisa, maitiro emuchina wekukanda pasina kuvhundutsa, maitiro ekusarudza alloy inozogadzira yakachena uye kuita mumunda, uye kana ± 0.001 kushivirira kwakanaka zvakakwana.
Muedzo wekupedzisira unogara uri chikamu chekushandisa. Ndakaona ma screws akagadzirwa zvakanaka achitadza nekuti iko chaiko kwaingodzika ganda. Uye ndakaona zvikamu zvine nzvimbo shoma dzakakasharara panzvimbo dzisiri dzakakosha dzichiita zvisina mhosva kwemakumi emakore nekuti iwo akakosha maficha akaitwa nekunzwisisa kwakadzama kwezvinhu, maitiro, uye basa. Ndicho chinangwa chaicho. Izvo zvakashata, zvinodzokorora, uye zvizere nekufona kwekutonga. Uye ndizvo zvinoita kuti ive hunyanzvi chaihwo, kwete mutsara papepa rekugona.
