Mukugadzira nemazvo, kugadzira zvinhu zvemuchadenga, uye zvitoro zvematurusi nemidziyo yepamusoro muEurope neNorth America, pane chokwadi chakanyarara asi chakakosha chinoraramirwa nenyanzvi dzemetro: zvisinei nekuti zvishandiso zvako zvakakwirira sei, zviyero zvako zvinongovimbika sepamusoro pazvinorehwa. Uye kana zvasvika pakurongeka kwehwaro, hapana chinhu—ingava simbi yakaumbwa, ingava simbi, kana chinhu chakasanganiswa—chinoenderana nekugadzikana kusingaperi kweplate yekuongorora yegranite. Asi pasinei nebasa rayo guru, chinhu ichi chakakosha chinowanzoonekwa sebhenji rebasa risingashande pane chiyero chemetrology chazviri chaizvo.
Mhedzisiro yekusashanda zvakanaka kwechinhu ichocho inogona kunge iri nyore asi inodhura. Nyanzvi yemakanika inogadzirisa chinhu chakaomarara ichishandisa mageji ekukwirira paplate yakasakara kana isina chitupa. Muongorori anoongorora kuti nzvimbo yekuvharira yakatsetseka sei nechiratidzo che dial chakaiswa pachigadziko chakakombama. Mainjiniya wemhando yepamusoro anobvumidza batch yakavakirwa padata reCMM risati rambosimbiswa zvichienderana nepurani inozivikanwa. Muchiitiko chimwe nechimwe, maturusi anogona kunge achishanda zvakanaka—asi hwaro huri pasi pawo hwakakanganisika. Ndosaka kunzwisisa kugona, miganhu, uye kushandiswa kwakakodzera kweplate yako yekuongorora granite, kunyanya pakushanda nehurongwa hukuru hweplate yegranite, hakusi kungori tsika yakanaka chete—chinodiwa kuchengetedza hunhu hunoteverwa uye hunodzivirirwa.
Granite ndiyo yainyanya kusarudzwa pakugadzira zvinhunzvimbo dzekutarisa zvakaruramakubvira pakati pezana remakore rechi20, uye nekuda kwezvikonzero zvesainzi zvinonzwisisika. Maumbirwo ayo akakora, akapfava, anopa kuomarara kwakanyanya, kuwedzera kushoma kwekupisa (kazhinji 6–8 µm/m·°C), uye kuderedza kusimba kwechisikigo—zvose zvakakosha pakuyera kunodzokororwa. Kusiyana nemaplate esimbi, ayo anoora, anochengetedza kushushikana, uye anokura zvinooneka nekuchinja kwekushisa kwemhepo, granite inoramba yakagadzikana mativi ayo pasi pemamiriro ezvinhu akajairwa eworkshop. Ndosaka mitemo yakaita seASME B89.3.7 neISO 8512-2 ichitsanangura granite—kwete sechinodiwa, asi sechinodiwa chekutanga—kumaplate epamusoro eGiredhi 00 kusvika Giredhi 1 anoshandiswa mukuyera nekuongorora.
Asi kukura kunounza matambudziko matsva.ndiro yepamusoro yegranite—ngatitii, 2000 x 1000 mm kana kupfuura—haisi kungori shanduro yakakwidziridzwa yeplate yebenchtop. Huremu hwayo (hunowanzo pfuura 800 kg) hunoda hunyanzvi hwayo hwekutsigira kudzivirira kudzika. Kupisa kwemafuta mukati mehukuru hwayo kunogona kugadzira ma "micro-curvatures" kana isina kuenderana nemazvo. Uye nekuti kushivirira kwekutsetseka kunokura nehukuru (semuenzaniso, ±13 µm yeplate ye2000 x 1000 mm Grade 0 paISO 8512-2), kunyangwe kutsauka kudiki kunova kwakakosha padaro refu. Apa ndipo panosangana hunyanzvi neinjiniya: maplate echokwadi egranite makuru haangochekwa nekuporishwa chete—anorerutswa kushushikana kwemwedzi yakawanda, anonamirwa nemaoko kwemavhiki, uye anosimbiswa uchishandisa laser interferometers kana mazinga emagetsi pamazana enzvimbo pamusoro.
Zvakakoshawo kuti mapurati aya anosangana sei nezvishandiso zvekuyera mapurati epamusoro. Mageji ekukwirira, zviratidzo zvekuyedza kudhirowa, mabharu esine, masikweya ekugadzirisa, magage blocks, uye ma optical comparator zvese zvinofungidzira kuti pasi pevhu rakakwana. Kana zvisiri, kuverenga kwese kunogara nhaka chikanganiso ichocho. Semuenzaniso, kana uchishandisa digital height gauge kuyera step heights pa engine block, 10-micron dip muplate inoshandura zvakananga kuita 10-micron error muhukuru hwako hwakataurwa—kunyangwe kana gauge yacho pachayo yakaongororwa zvakakwana. Ndosaka ma lab epamusoro asingangove ne granite plate chete; vanoibata senzira yekugara, kuronga kudzokororwa kwekugadzirisa nguva dzose, kudzora kusvibiswa kwezvakatipoteredza, uye kunyora mashandisirwo ese.
PaZHHIMG, takazvionera toga kuti kuchinja kuenda kuplate yekuongorora yegranite yakagadziriswa kunoshandura sei mhedzisiro yemhando yepamusoro. Mumwe mugadziri wemold wekuEurope akatsiva tafura yavo yesimbi yekare neplate yegranite yeGrade 0 ye1500 x 1000 mm uye akaona kusiyana kwekuyera kwevashandisi vepakati kuchiderera ne40%. Zvishandiso zvavo hazvina kuchinja—asi zvavakareva zvakachinja. Mumwe mutengi mubazi rezvekushandisa zvekurapa akapasa ongororo yakaoma yeFDA mushure mekupa zvitupa zvekugadzirisa zvizere zveplate yavo huru yegranite, zvichiratidza kuti zvinoenderana nemitemo yenyika. Izvi hazvisi zvibodzwa zvega; mhedzisiro inofungidzirwa kana ukasimbisa metrology yako muchokwadi chemuviri.
Zvakakoshawo kubvisa ngano yakajairika: kuti granite inopwanyika. Kunyange zvazvo inogona kutsemuka kana ikarohwa nesimbi yakaoma, inogara kwenguva refu kana ishandiswa zvakajairika. Haina ngura, haidi mafuta, uye haikanganisike nehunyoro kana kuchinja-chinja kwekupisa kuri pakati nepakati. Nekutarisirwa kwakakosha—kuchenesa nguva dzose neisopropyl alcohol, kudzivirira kuputika zvakananga, uye kutsigira kwakakodzera—yemhando yepamusorondiro yegraniteinogona kugara kwemakore makumi matatu kana kupfuura. Mapureti mazhinji akaiswa muma1970 achiri kushandiswa zuva nezuva nanhasi, kupfava kwawo kusina kuchinja.
Pakusarudza plate yekuongorora pamusoro pegranite, tarisa zvinopfuura runako. Simbisa giredhi (Giredhi 00 remarabhoritari ekugadzirisa, Giredhi 0 rekuongorora kwakanyatsojeka), simbisa kuti chitupa chinosanganisira mepu yekutsamira (kwete chitambi chekupasa/kukundikana chete), uye iva nechokwadi chekuti mutengesi anopa gwara rekugadzirisa, kubata, uye kugadzirisa nguva. Kune ma granite surface plate makuru, bvunza nezvema custom stands ane tsoka dzinogadziriswa uye vibration isolation - zvakakosha kuchengetedza kururama munzvimbo dzekugadzira.
Uye yeuka: zvishandiso zvako zvekuyera pamusoro peplate zvinongoenderana nepamusoro pazvo chete. Gaugeonawarpedtable ine hurefu hwe10,000haingori accuratethana100 iri paplate yegranite yakasimbiswa. Kunyatsoongorora hakusi kwechishandiso chinodhura zvakanyanya—asi kutaura nezvechinhu chakavimbika kupfuura zvese.
KuZHHIMG, tinoshanda pamwe chete nemaworkshop epamusoro anosanganisa matekiniki ekugadzira machira ekugadzira nekuongorora kwemetrology kwemazuva ano. Plate yega yega yatinopa inoedzwa yega yega, inorongwa seri, uye inoperekedzwa nechitupa chakazara cheNIST-traceable. Hatitendi mu "pedyo zvakakwana." Mumetrology, hapana chinhu chakadaro.
Saka zvibvunze kuti: kana chikamu chako chakakosha chikapasa ongororo yekupedzisira, unovimba nenhamba yacho here—kana kuti ubvunze pamusoro pechinhu chiri pasi payo? Mhinduro yacho inogona kusarudza kana ongororo yako inotevera ikabudirira kana kuti kudzokera shure. Nekuti munyika yekururama, kuvimbika kunotangira kubva pasi zvichienda mberi. Uye kuZHHIMG, takazvipira kuve nechokwadi chekuti pasi rakasimba, rakagadzikana, uye rakanaka nesainzi.
