Nayi funso lomwe ndimakonda kufunsa oyang'anira shopu yolondola: ndi liti nthawi yomaliza yomwe mudakhulupiriradi malo anu osungira zinthu?
Osati “ikuwoneka ngati yathyathyathya.” Osati “yadutsa muyeso wobwera.” Ndikutanthauza wodalirika — mtundu wa chidaliro kumene mumayika gawo latsopano pa iyo, kuyeza miyeso yanu, ndikudziwa kuti manambala omwe mukuwerenga ndi okhudza gawolo, osati za mbale yomwe ikuyandama pansi pake.
Anthu ambiri amakayikira. Ena amasintha nkhani. Ena amavomereza kuti sakudziwa chifukwa sanafufuzepo.
Ndi poyambira pa zokambirana zonsezi.
Chifukwa Chake Mapepala Okhala Pamwamba Akadali Ofunika Kwambiri Kuposa Zimene Ogula Ambiri Amaganiza
Tikukhala mu nthawi ya ma laser interferometers, machitidwe owonera, ndi ma touch probe omwe amatha kuyeza zinthu zazing'ono m'masekondi ochepa. N'zosavuta kuwona pamwamba pa mbale ngati chinthu chotsalira - mwala wolemera wathyathyathya (kapena chidutswa cholemera cha chitsulo chopangidwa ndi chitsulo) chomwe chili pakona ya chipinda chowunikira chomwe sichichita chilichonse.
Kupatula kuti imachita pafupifupi chilichonse.
Chidebe cha pamwamba ndi malo ofotokozera omwe miyeso yambiri yamanja ndi theka lamanja imagwiritsidwira ntchito. Kuwerenga kulikonse kwa ma micrometer komwe mumatenga ndi geji yoyezera kutalika, kukhazikitsidwa kulikonse kwa chizindikiro choyesera, kufananiza kulikonse pakati pa chidutswa chopangidwa ndi makina ndi muyezo wofotokozera - zonse zimadutsa pamwamba pomwe gawolo lili. Ngati pamwambapo sipakhazikika komanso kutentha kumadziwikiratu, muyeso uliwonse womwe uli pansi pa mtsinje uli ndi cholakwika chosawerengeka.
Chowonadi chosasangalatsa ndichakuti masitolo ambiri akugwiritsa ntchito njira zowongolera khalidwe pa maziko omwe sanakayikirepo kwa zaka zambiri. Nthawi zina kwa zaka zambiri.
Chitsulo Choponyedwa ndi Granite: Kuyerekeza Kwenikweni Palibe Amene Amachita Bwino
Pitani ku malo khumi opangira zinthu zolondola ndipo mupeza kugawanika kwa 50/50 pakati pa chitsulo chopangidwa ndi granite ndi miyala yachitsulo. Funsani ogula chifukwa chake adasankha zomwe adasankha, ndipo ambiri adzakupatsani yankho lomwe likumveka bwino koma silikupitirira kufufuzidwa.
"Ndinasankha chitsulo chopangidwa ndi pulasitiki chifukwa ndi chachikhalidwe."
"Ndinasankha granite chifukwa ndi yokhazikika."
Mayankho onse awiriwa ndi osakwanira. Umu ndi momwe dongosolo lenileni la zisankho limaonekera:
Mapepala achitsulo opangidwa pamwambaZakhala zikudziwika bwino m'mafakitale kwa zaka zoposa zana, ndipo pazifukwa zomveka. Zili ndi makhalidwe abwino kwambiri ochepetsera chinyezi - zimayamwa kugwedezeka bwino kuposa granite, zomwe ndizofunikira kwambiri m'malo olemera opangira makina. Zimakhalanso zosavuta kuzibwezeretsanso zikagwiritsidwa ntchito. Katswiri wamakina waluso amatha kukanda mbale yachitsulo yosweka kuti ibwerere ku zomwe zafotokozedwa mwachangu, zomwe zimapangitsa kuti kukonza kukhale kosavuta.
Kusinthaku ndi kutentha kwambiri. Chitsulo chopangidwa ndi chitsulo chimakula ndikuchepa kwambiri ndi kusintha kwa kutentha. Mbale yachitsulo chopangidwa ndi chitsulo m'sitolo yosatenthedwa m'nyengo yozizira imachita zinthu mosiyana ndi mbale yomweyi m'chilimwe. Pa ntchito yomwe imafuna kulondola kwa micron pamiyeso yayikulu, kusinthaku kwa kutentha sikophweka.
Mapepala a pamwamba pa graniteKonzani vuto la kutentha bwino. Granite wakuda uli ndi mphamvu yochepa kwambiri yokulitsa kutentha komanso kukhazikika kwapadera pa kutentha kwabwinobwino. Granite plate sifunikira kulamulira nyengo kuti igwire bwino ntchito monga momwe chitsulo chopangidwa chimachitira. Sichiwononga, sichichita dzimbiri, ndipo sichifuna mafuta.
Kusinthana ndi kuthekera kokonza. Pamene pamwamba pa granite pawonongeka kapena kuwonongeka, simungathe kuikwapulanso momwe mungachitire ndi chitsulo chosungunuka. Mukuyang'ana kuyikanso (kokwera mtengo komanso kotenga nthawi) kapena kuisintha. Ichi ndichifukwa chake mtundu woyamba wa zinthu ndi kulondola kwa kupanga ndikofunikira kwambiri pa granite - mukupanga kudzipereka kwa nthawi yayitali pogula.
Chofunika kwambiri m'munda: pa ntchito zambiri zowunikira m'malo olamulidwa, kukhazikika kwa kutentha kwa granite kumapereka mwayi woyerekeza. Pa makina olemera komanso kusonkhanitsa kwakukulu komwe kumachepetsa kugwedezeka ndi kukonzanso ndikofunikira, chitsulo chopangidwa chimapezabe malo ake.
Kufotokozera kwa Dongosolo la Magiredi: Zimene Mukugula Kwenikweni
Zambiri zomwe zimafotokoza za pamwamba pa mbale zimagwiritsa ntchito miyezo monga DIN 876, ASME GGGP-463C, kapena ISO 8512. Miyezo imeneyi imafotokoza magiredi olondola — nthawi zambiri Giredi 00, Giredi 0, Giredi 1, ndi Giredi 2 — kutengera kulekerera kwa flatness.
Apa ndi zomwe magiredi amenewo amatanthauza pochita, pogwiritsa ntchito muyezo wa DIN 876 ngati chisonyezero:
Giredi 00 imalola pafupifupi ma microns 2.3 a flatness deviation over 1,000mm. Giredi 0 imalola pafupifupi ma microns 4.6. Giredi 1 imalola pafupifupi ma microns 9.2. Giredi 2 imalola pafupifupi ma microns 18.5.
Kachitidwe ka kuwirikiza kawiri sikofunikira — sitepe iliyonse yotsika mu giredi ikuyimira kuwirikiza kawiri kwa cholakwika chololedwa. Ndipo bajeti ya cholakwikacho iyenera kuphimba osati kulekerera kokha kwa kupanga, komanso kuwonongeka kwa mbaleyo pa nthawi yonse ya ntchito yake.
Ponena za nkhaniyi: ngati mukuyeza zinthu zopangidwa ndi makina kufika pa ±2 microns, mbale ya pamwamba ya Giredi 1 (9.2 microns ya kupotoka kovomerezeka kwa flatness) ikuyamba kale kugwiritsa ntchito pafupifupi 20% ya gulu lanu lonse la tolerance — musanaganizire za gwero lina lililonse losatsimikizika la kuyeza. Imeneyo ndi nambala yoyenera kuigwiritsa ntchito.
Ichi ndichifukwa chake ma lab ofunikira kwambiri a metrology ndi makina abwino a ndege nthawi zambiri amatchula Giredi 00. Mtengo wowonjezera wa mbale yapamwamba ndi wochepa poyerekeza ndi mtengo wa cholakwika chosazindikirika choyesa chomwe chimagwera m'magulu azinthu zosagwirizana.
Kodi N’chiyani Chinapha Mbale Yanu Yomaliza Yokhala Pamwamba (Ndi Zimene Zabwino Zimaletsa)
Ma plates a pamwamba salephera kwambiri. Amayandama. Amayamwa chinyezi. Amasonkhanitsa kuwonongeka kwa pansi pa nthaka kuchokera ku zonyamulira zogwirira ntchito zomwe zagwa. Amapanga mawonekedwe ovalika m'malo osiyanasiyana chifukwa chokhudzana mobwerezabwereza ndi malo omwewo.
Njira yofala kwambiri yolephera kwa mbale zachitsulo zoponyedwa m'malo onyowa ndi kusintha kwa mawonekedwe chifukwa cha chinyezi. Ngakhale mutapaka mafuta moyenera, chitsulo choponyedwa chimakhala ndi mabowo okwanira kuyamwa nthunzi ya madzi pakapita nthawi, makamaka m'malo opanda nyengo yowongolera. Zotsatira zake ndi kutayika pang'onopang'ono kwa kusalala komwe sikumawonekera pa satifiketi yoyezera koma kumaonekera nthawi iliyonse mukayesa kusunga kulekerera kwamphamvu.
Ma granite plates amalephera mosiyana. Vuto lofala kwambiri si vuto la granite - ndi vuto la kutentha kwambiri. Granite plate yomwe yakhala m'nyumba yosungiramo zinthu yozizira kenako nkuiyika m'chipinda chowunikira chofunda komanso chonyowa imatha kukhala ndi vuto la komweko lomwe limayambitsa ming'alu yaying'ono pansi pa nthaka. Izi sizichitika ndi kuzolowera bwino, koma m'dziko lenileni, zinthu zimasunthika mwachangu.
Njira ina yolephera pa zinthu zonse ziwiri ndi kuwonongeka kwa kugunda. Chogwirira ntchito chachitsulo chogwetsedwa, malo osasamalidwa bwino a chipika cholemera - izi zimapangitsa kuti pakhale mabala kapena zizindikiro za chip zomwe zimakhala zozungulira zomwe zimakhala zodzaza ndi kupsinjika maganizo komanso zolakwika za geometric reference. Ma plate abwino a pamwamba amabwera ndi zonyamulira zoteteza makamaka kuti apewe izi, ndipo ogwiritsa ntchito ambiri amanyalanyaza malangizowo mpaka atayambitsa kale vuto.
Zachilengedwe Zomwe Palibe Amene Amalankhulapo
Mbale ya pamwamba yomwe ili pamalo osalinganika bwino ndi mbale ya pamwamba yomwe yawonongeka. Choyimiliracho, njira yoyikira, ndi malo ozungulira zonse zimathandiza kuti mbaleyo igwire bwino ntchito.
Pa mbale zachitsulo zopangidwa ndi chitsulo, njira yachikhalidwe ndi malo oimikapo makabati okhala ndi mapazi osinthika olinganiza. Lingaliro ndikuyika mbale mkati mwa mphindi zochepa kuchokera pa mulingo, kenako lolani kulemera kwa mbaleyo kugawire kusalingana kulikonse kotsala. Izi zimagwira ntchito bwino, koma zimaganiza kuti pansi ndi wolimba bwino ndipo sipagwedezeka pamene pali katundu.
Pa mbale za granite, makamaka mbale zazikulu, kapangidwe kolimba, kochirikiza ka monolithic ndikofunikira kwambiri. Granite ndi yolimba koma yophwanyika — siisinthasintha kuti igwirizane ndi kusalingana pang'ono kwa maziko monga momwe chitsulo chopangidwa chimachitira. Mbale ya granite yomwe imathandizidwa pa maziko osafanana idzakhala ndi kupsinjika kosiyana komwe kumatha kuyambitsa ming'alu, makamaka ngati pali kutentha komwe kumachitika.
Zipangizo zofunika kwambiri: zonyamulira zoyenera zogwirira ntchito kuti zisawonongeke ndi kugundana, zophimba chivindikiro kuti zisawononge zinyalala ndi kuipitsidwa, ndi ziphaso zoyezera nthawi ndi nthawi kuchokera ku labu yovomerezeka. Mbale yopanda chiphaso choyezera chamakono ikulonjeza kuti singagwire ntchito.
Kupeza Zinthu Kuchokera kwa Wopanga Weniweni Mosiyana ndi Wogulitsa Katalogi
Izi ndizofunikira kwambiri kuposa momwe ogula ambiri amazindikira.
Mukagula mbale yopangira pamwamba kuchokera kwa ogulitsa omwe amachokera ku mafakitale osiyanasiyana, nthawi zambiri mumapeza chinthu chokhala ndi pepala lofotokozera koma chopanda mbiri yeniyeni yopangira. Simukudziwa amene adachipanga, zida zopangira zomwe zinagwiritsidwa ntchito, kapena ngati munthu amene anakanda pamwamba pake anali ndi zaka zitatu kapena makumi atatu zakuchitikira.
Kusiyana kumeneku kumawonekera mu kachitidwe ka m'mphepete, kusinthasintha kwa kapangidwe ka pamwamba, komanso kukhazikika kwa nthawi yayitali. Mbale ya pamwamba yochokera kwa wopanga wolondola yemwe wakhala ndi zaka zambiri akugwira ntchito yokanda ndi manja idzasunga mawonekedwe ake kwa nthawi yayitali chifukwa pamwamba pake padapangidwa mosamala kwambiri. Mbale yochokera kwa wogulitsa zinthu ikhoza kukwaniritsa zofunikira za kukhazikika panthawi yopereka - koma patatha miyezi isanu ndi umodzi, m'malo enieni a fakitale, kusiyana pakati pawo kumakhala koyezeka.
Funsani wogulitsa wanu mwachindunji: Ndani anapanga izi? Kuti? Kodi ndingathe kupita ku malo ogwirira ntchito? Kodi ogwira ntchito anu ali ndi zaka zingati zogwira ntchito yokanda? Kodi unyolo wanu wowerengera umapereka chidziwitso chotani?
Ogulitsa omwe amakana kuyankha mafunso amenewo akukuuzani zinazake.
Kupanga Chisankho Chabwino pa Ntchito Yanu
Chisankho si chitsulo chosungunuka poyerekeza ndi granite. Chimakhudza kufananiza zinthuzo ndi mtundu wake ndi zomwe mukufuna.
Ngati mukuyendetsa labu yowunikira yokhala ndi malamulo okhwima okhudza chilengedwe komanso zofunikira pakulekerera kwa micron: tchulani granite ya Giredi 00, yokhala ndi kutsata kwa kuwunikira ku bungwe la dziko lonse la metrology, komanso mulingo wolembedwa wa kutentha ndi chinyezi.
Ngati mukugwiritsa ntchito makina opangira zinthu okhala ndi zida zolemera komanso kugwedezeka kwakukulu pansi: mbale yachitsulo yothandizidwa bwino yokhala ndi kugwedezeka koyenera ingakhale yopambana granite, chifukwa kuyamwa kwa kugwedezeka ndikofunikira kwambiri kuposa kukhazikika kwa kutentha pamalo amenewo.
Ngati muli ku Southeast Asia komwe kuli nyengo yopanda mpweya woziziritsa: kukana chinyezi kwa granite sikofunikira. Ndi kusiyana pakati pa mbale yomwe imasunga mawonekedwe ake chaka chonse ndi yomwe imayendayenda nthawi iliyonse yamvula.
Ngati mukugula makina azachipatala kapena a ndege: funani zikalata zonse zolondola, satifiketi yovomerezeka yowunikira, ndi wopanga yemwe ali ndi luso lolemba m'magawo olamulidwawo. Zofunikira pakugula ndizofunikira kwambiri monga momwe zinthuzo zimakhudzira.
Chotsatira Pambuyo pa Mbale
Apa pali chinthu chomwe ogula ambiri a surface plate saganizirapo mpaka zitachedwa: surface plate ndi yodalirika ngati makina ozungulira.
Choyezera kutalika kwanu chiyenera kuyesedwa. Zizindikiro zanu zoyesera ziyenera kukhala bwino pamakina. Kulemba kutentha ndi chinyezi chanu kuyenera kukhala kwatsopano. Akatswiri anu ayenera kumvetsetsa momwe angaganizire kukula kwa kutentha poyesa zinthu zomwe zili pa kutentha kosiyana ndi mbale.
Mbale ya granite ya Giredi 00 siimakupatsani zotsatira zoyezera za Giredi 00 zokha. Imakupatsani malo odalirika oyezera. Unyolo wotsalawo uyeneranso kumangidwa bwino.
Ndikoyenera kukumbukira zimenezo nthawi ina munthu akakufunsani ngati mumakhulupirira mbale yanu ya pamwamba. Yankho lake mwina ndi lakuti “si kotheratu” — ndipo mwina kukonza kumayamba ndi kuyang'ana dongosolo lonse, osati mbale yokhayo.
Koma zimayamba ndi kugula mbale yoyenera poyamba.
