Mu malo ovuta kwambiri a uinjiniya wamakono wolondola, kulondola kwa zida zanu zoyezera kungapangitse kapena kusokoneza kutsatira kwa chinthucho. Ngakhale kuti malo osalala amawoneka osavuta, makampani otsimikizira khalidwe amadalira zida zovomerezeka, zopangidwa mwaluso, zomwe sizofunika kwambiri kuposa mbale ya granite pamwamba. Kwa akatswiri omwe amafuna zabwino kwambiri, kumvetsetsa kusiyana kwa kulondola, udindo wa opanga ovomerezeka monga mbale ya granite ya ZHHIMG, komanso kufunikira kwa chithandizo choyenera si njira yabwino yokha - ndikofunika kwambiri pazachuma.
Kupitirira Kusalala: Kuzindikira Magiredi Olondola a Granite Plate
Pofufuza maziko oyezera, mainjiniya ayenera kuyang'ana kwambiri zinthuzo ndikuyang'ana kwambiri kulekerera komwe kumachitika panthawi yolumikizirana mozama. Kulekerera kumeneku kumatanthauza giredi, chitsimikizo cha momwe mbaleyo imamatirira bwino kwambiri ku dongosolo langwiro komanso lachiphunzitso. Makampaniwa amagwiritsa ntchito njira yomveka bwino, pomwe kulekerera kolimba kumafanana ndi giredi inayake, nthawi zambiri kutsatira miyezo monga Federal Specification GGG-P-463c kapena DIN 876. Kulondola kwakukulu kumayimiridwa ndi giredi AA granite surface plate (nthawi zina imatchedwa Giredi 00). Ma plate awa amapereka kusiyana kochepa kwambiri kovomerezeka kwa kusalala pamwamba ponseponse. Ndiwo muyezo, womwe umagwiritsidwa ntchito makamaka m'ma laboratories akuluakulu olamulidwa ndi chilengedwe kuti azitha kuwerengera zida zolondola kwambiri. Ngati ntchito yanu ikuphatikiza kutsimikizira miyezo yowunikira kapena kukankhira malire a muyeso wa miyeso, Giredi AA ndiyo chisankho chokhacho chovomerezeka.
Potsika pang'ono, koma tikukhalabe mkati mwa malo olondola kwambiri, timapeza mbale ya granite ya giredi 0 (kapena Giredi A). Giredi iyi ndiye maziko a zipinda zabwino kwambiri zowunikira komanso madipatimenti owongolera khalidwe. Imapereka kusalala kwapadera kofunikira pakulinganiza zida zapamwamba, kuchita ntchito zofunika kwambiri zokhazikitsa, ndikuyang'ana ziwalo ndi zolekerera zolimba kwambiri. Kusiyana kwa kulekerera konse kwa kusalala pakati pa Giredi AA ndi Giredi 0 ndikoyezeka, koma pa ntchito zambiri zowunikira zachiwiri ndi zapamwamba, Giredi 0 imapereka magwiridwe antchito abwino komanso ogwira ntchito. Ngakhale miyezo imagwiritsidwa ntchito padziko lonse lapansi, kukhazikika kwa kukwaniritsa magiredi awa kumadalira ukatswiri wa wopanga, zida, ndi kupeza zinthu. Makampani monga ZHHIMG amadzisiyanitsa okha potsatira kwambiri miyezo yapadziko lonse lapansi, kuonetsetsa kuti mukagula mbale ya Giredi AA kapena Giredi 0, kusatsimikizika komwe kwalembedwako ndikodalirika komanso kolondola. Kwa ogula omwe amazolowera mitundu yodziwika bwino, khalidweli liyenera kupikisana kapena kupitirira magwiridwe antchito omwe amayembekezeredwa kuchokera ku chipangizo chapamwamba kwambiri, monga mbale ya granite ya grizzly, mwa kusunga ulamuliro wokhwima pa njira yonse yopangira ndi kumaliza.
Ngwazi Yosaimbidwa: Choyimilira cha Granite Surface Plate
Cholakwika chofala kwambiri pakupanga metrology ndikuyang'ana kwambiri pa kalasi ya plate pomwe kunyalanyaza chithandizo chake. Mbale ya Giredi AA yomwe imayikidwa pa maziko osakwanira kapena osapangidwa bwino, mwa magwiridwe antchito, siili bwino kuposa mbale yotsika kwambiri. Kapangidwe kothandizira kulemera kwa granite kuyenera kuletsa kupatuka, kupatula kugwedezeka, ndikulola plateyo kuti itenge ngati yopangidwa bwino. Apa ndi pomwe choyimilira cha granite pamwamba pa plate chimakhala chinthu chofunikira kwambiri.
Ma stand awa adapangidwa mwapadera kuti athandizire mbaleyo pa Airy Points kapena Bessel Points zomwe zimawerengedwa mwa masamu. Ma point awa ndi malo abwino kwambiri ochepetsera kupotoka kwa mbale yonse ndi kupotoka chifukwa cha kulemera kwake. Tebulo lodziwika bwino silingagawire kulemera kwakukulu kumeneku molondola, zomwe zimapangitsa kuti zolakwika zoyezeka ziwonekere mu reference plane. Kuphatikiza apo, ma stand apamwamba nthawi zambiri amakhala ndi zinthu zomangirira kugwedezeka kapena mapazi olinganiza, zomwe zimathandiza kupatula mbale yomvera ku kugwedezeka kwa pansi komwe kumachitika chifukwa cha makina apafupi, kuyenda kwa mapazi, kapena machitidwe a HVAC. Izi ndizofunikira kwambiri pama plate a Giredi AA ndi Giredi 0 komwe kugwedezeka pang'ono kumatha kuwononga miyeso yofunika. Pomaliza, granite surface plate stand yabwino imakhala ndi ma leveling jacks olimba omwe amalola wogwiritsa ntchito kulinganiza bwino mbaleyo. Ngakhale mphamvu yokoka imatsimikizira kuti pamwamba pake ndi "lathyathyathya" malinga ndi reference plane yake, kulinganiza ndikofunikira pakugwiritsa ntchito ma bubble levels, ma electronic levels, ndi zida zina zoyezera (monga column gauges) zomwe zimadalira reference yoyima kapena yopingasa ku gravitational plane. Kugula mbale ya Giredi 0 kuchokera kwa ogulitsa odziwika bwino monga ZHHIMG popanda reside yolondola ndi mwayi wosowa. Ndalama zomwe zimayikidwa mu kulondola kwa mbaleyo zimawonongeka ngati kapangidwe kothandizira kamayambitsa kupotoka komwe kumaposa kulekerera kwa mbaleyo.
Nkhani ya Granite Yakuda Yovomerezeka
Ngakhale mitundu yosiyanasiyana ya granite imagwiritsidwa ntchito, mbale zolondola kwambiri—makamaka zomwe zimafika pamlingo wa granite pamwamba pa mbale ya AA—nthawi zambiri zimapangidwa kuchokera ku granite wakuda (monga Diabase wakuda kapena Impala Black). Zipangizozi sizimasankhidwa chifukwa cha kukongola kwake kokha komanso chifukwa cha mawonekedwe ake apamwamba. Granite wakuda nthawi zambiri imakhala ndi porosity yotsika, zomwe zikutanthauza kuti imayamwa chinyezi chochepa, ndipo kukhazikika kwa gawoli ndikofunikira kwambiri pakusunga kulondola kwa grade pamlingo wosiyanasiyana wa chinyezi. Ndi wokhuthala komanso wokhuthala ndipo uli ndi Modulus of Elasticity yapamwamba kuposa granite wopepuka, zomwe zimathandiza mbale kuti isagwedezeke pansi pa kulemera kwa zida zoyezera ndi zida zina. Chofunika kwambiri, coefficient of thermal expansion (CTE) ndi yotsika kwambiri. Izi zikutanthauza kuti ngati kutentha kusinthasintha m'chipinda chowunikira, granite plate imasintha kukula kwake pang'ono kuposa china chilichonse, kusunga umphumphu wa reference plane. Mukasankha chinthu chapamwamba kwambiri monga granite plate ya ZHHIMG, mukugula phukusi lonse la sayansi ya zinthu, lomwe limaphatikizapo mawonekedwe apamwamba a granite yokha, kuphatikiza ndi akatswiri olumikizana.
Kusamalira ndi Moyo Wanu: Kusunga Ndalama Zanu
Kutalika kwa mbale ya granite ya kalasi 0 kapena chida chilichonse cholondola kwambiri kumadalira chisamaliro chake. Kunyalanyaza kungachepetse kulondola kwake mwachangu, kusandutsa Giredi 0 kukhala Giredi 1 kapena kuipiraipira, ndipo kungafunike kukonzanso kapena kubwerezanso ndalama zambiri. Kusamalira nthawi zonse kumafuna kuti munthu asagwiritse ntchito zotsukira zapakhomo kapena zipangizo zokwawa; zotsukira mbale zapadera zimapangidwa kuti zichotse mafuta, fumbi, ndi zodetsa zazing'ono popanda kuwononga pamwamba. Fumbi ndi grit, kwenikweni, ndiye chifukwa chachikulu cha kuwonongeka kwa malo. Kuphatikiza apo, njira yoyenera yolerera imafuna kuyika zinthu zogwirira ntchito mofatsa, osasuntha kapena kukoka zinthu zolemera kapena zokwawa pa granite, chifukwa kuwonongeka pang'ono komwe kumachitika chifukwa cha izi kumawonongeka pamwamba pakapita nthawi. Kutsatira ndondomeko yokhwima yowerengera (nthawi zambiri miyezi 6 mpaka 12 ya mbale zapamwamba zomwe zimagwiritsidwa ntchito kwambiri) sikungakambirane. Kuwongolera kumatsimikizira kuti kusalala kwa mbale kumakhalabe mkati mwa kulekerera kwake kovomerezeka ndipo kumapereka mbiri yovomerezeka ya kulondola kwake. Pomaliza pake, kuyika ndalama pa maziko abwino kwambiri—kaya ndi mbale ya granite yapamwamba ya AA ya labu kapena malo olimba okhala ndi mbale ya granite ya ZHHIMG pamwamba pa malo oimikapo granite—ndi umboni wa kudzipereka kwa kampani ku khalidwe labwino. Kusiyana pakati pa muyeso wolondola ndi gawo lolephera nthawi zambiri kumadalira pa umphumphu wa chipangizo chimodzi chokha, chopanda phokoso, komanso chofunikira ichi.
