Munyika yeinjiniya yekunyatsogadzirisa zvinhu—kungave uri kuvaka michina midiki yemidziyo yekurapa, kugadzirisa zvikamu zveoptical, kana kusimbisa fittings dzemuchadenga dzinoshivirira zvakanyanya—muganhu wekukanganisa mudiki chose. Asi nyanzvi zhinji dzinofuratira chinhu chiri nyore asi chakakosha chinogona kukanganisa chinyararire kunyangwe mashandiro epamusoro-soro: nzvimbo yekutarisa yavanoshandisa zuva nezuva. Hazvisi nguva dzose nezvekunaka kwemidziyo yenyu; dzimwe nguva, ndezvekugadzikana kuri pasi payo. Uye kana nzvimbo iri shoma kana mabasa ari madiki, mini surface plate yakakodzera inogona kuita mutsauko wese.
Kunyange zvazvo matafura makuru ekuongorora granite ari pamusoro pemarabhoritari emetrology, zvitoro zvidiki, madhipatimendi eR&D, uye mapoka ebasa remumunda anowedzera kuvimba nemapuratifomu egranite akamanikana, epamusoro-soro kuti ave nechokwadi chekuti nzvimbo yebhenji iri diki uye kutakura kwacho kunokosha. Izvi hazvisi zvishandiso "zvishoma" - mhinduro dzakagadzirirwa kupa hunhu hwakafanana uye kushanda kwakaenzana nehwevamwe vavo, dzakangogadzirwa kuti dzishande zvakanaka. Dzakabatanidzwa nedzakavimbika.maturusi ekuyera granite— zvakaita semageji ekukwirira, zviratidzo zvekudhirowa, magage blocks, uye mapoinzi ekugadzirisa zvinhu—ndiro diki inova sero remetrology rinotakurika, zvichiita kuti kuyerwa kuonekwe kubva pasi pekugadzira kusvika pabhenji remukamuri rekuchenesa.
Asi heino mhinduro: saizi haikuregi iwe uchibvisa mutoro wekugadzirisa. Kungofanana nemasisitimu makuru, aya mareferensi madiki anoda kuyera tafura yepamusoro penguva nenguva kuti irambe yakavimbika. Kutsauka kwema microns mashanu chete paplate ye 200 x 300 mm kunogona kuita sekusina basa - kusvika wave kuyera kutsungirira kwe 0.01 mm pamuromo we injector fuel kana kugadzirisa semiconductor wafer handler. Pachiyero ichocho, kunyangwe microscopic warpage kana kupfeka kwenzvimbo kunogona kupinda mukuverenga kwenhema, kugadzirisa patsva, kana kusaenderana kusingaonekwe. Ndosaka vagadziri vanotungamira vachibata granite yega yega reference - pasinei nehukuru - sechinhu chakagadziriswa, kwete dombo chete.
Sainzi iri shure kwekuvimbika uku iri muhunhu hwegranite nhema yegiredhi remetrology pachayo. Kusiyana nesimbi yakakandwa kana simbi, iyo inowedzera nekuchinja kwetembiricha uye inoora nekufamba kwenguva, granite inopa kugadzikana kwakanyanya. Kuwanda kwayo kwakaderera kwekuwedzera kwekupisa (kazhinji 6–8 µm/m·°C), kuwanda kwakanyanya (~2.97 g/cm³), uye hunhu hwechisikigo hwekudedera-kunyorovesa zvinoita kuti ive yakakodzera kushanda nemazvo. Kana yakabatana zvakanaka kusvika kuGrade 0 kana Grade 00 flatness zvichienderana neISO 8512-2 kana ASME B89.3.7 standards, mini surface plate inopa geometric plane chaiyo inoramba yakafanana mumamiriro ese eworkshop.
Kuenderana uku ndiko kunoita kuti zvive zvechokwaditafura yegranitemaitiro ekuyera. Ungave uchikwinya magage blocks kuti uise master yekukwirira, uchitarisa squareness ne precision angle plate, kana kushandisa lever-type dial indicator kuti uone kumhanya, cheni yese yekuyera inofunga kuti base surface yakakwana. Kana isiriyo, kuverenga kwese kunogara nhaka chikanganiso ichocho - chinyararire uye chisingaonekwe. Ndosaka masisitimu emhando yepamusoro asingangove ne granite surfaces chete; anonyora nhoroondo yavo ye calibration, anotonga nharaunda yavo, uye anovarega chete kana recalibration ichiratidza kuti yafamba kupfuura miganhu inogamuchirika.
KuZHHIMG, takashanda nevatengi vakatanga varamba kudiwa kwemini surface plate ine certification, tichifunga kuti bhenji remuchina wavo kana chidimbu chegranite chakaraswa zvaizokwana. Mumwe mugadziri wezvemagetsi muGermany akawana kuti probe tip calibrations dzisingaenderane dzakateverwa kumashure kune aluminium base yakakombama yavagara vachishandisa kwemakore. Mushure mekuchinjira kune 300 x 450 mm Grade 0 mini surface plate ine full calibration certification, kudzokorora kwavo kwakavandudzika neanopfuura 60%. Zvishandiso zvavo hazvina kuchinja—asi foundation yavo yakanga yachinja.
Zvakakoshawo kuti maplate aya madiki anobatanidzwa sei nezvishandiso zvekuyera granite zvemazuva ano. Mageji ehurefu hwedhijitari, macomparators ekuona, uye kunyange maoko eCMM anotakurika anowanzoda referensi yakagadzikana, yakati sandara yekuisa kana yekusimbisa. Mini plate yemhando yepamusoro inoshanda sechibatiso ichocho, ichiva nechokwadi chekuti kurongeka hakukanganiswi nenzvimbo isina kuenzana kana isina kugadzikana pakupisa. Kune mainjiniya emumunda ari kugadzira kana kugadzirisa panzvimbo yacho, granite plate inotakurika inova chiyero chekufamba-famba—zvichiunza chivimbo chemhando yepamusoro munzvimbo dziri kure.
Uye zvinopesana nezvinotendwa nevakawanda, granite haiputsike kana ikashanda. Kunyange zvazvo ichigona kupwanyika kana ikarohwa zvakananga nesimbi yakaoma, haipindi mukushandiswa kwezuva nezuva. Haipedzi ngura, haidi mafuta, uye haipindi muhunyoro. Nekutarisirwa kwakakosha—kucheneswa nguva dzose neisopropyl alcohol, kudzivirira kukuvadzwa zvakanyanya, uye kuichengeta yakati sandara—inogona kupa makumi emakore ebasa rakavimbika. Mapuleti madiki mazhinji atakaona achishandiswa kubvira pakutanga kwema2000 achiri kusangana nemaitiro awo ekutanga ekuti akapfava, nekuda kwekubata zvakanaka uye kurongeka kwetafura yepamusoro.
Pakusarudza plate diki yepamusoro, tarisa zvinopfuura saizi. Simbisa giredhi rekuti rakatsetseka nekusimbisa chaiko—kwete zvirevo zvekushambadzira. Iva nechokwadi chekuti granite yakatsetseka, yakasununguka kushushikana, uye haina mitswe kana mitsipa ye quartz inogona kukanganisa kugadzikana. Vatengesi vane mukurumbira vanopa magwaro akazara, kusanganisira mepu yekuti rakatsetseka inoratidza kutsauka kubva pamusoro kuenda kumupata. Kune mashandisirwo akakosha, funga nezvemaplate ane nhamba dzeserial uye zvitupa zveNIST-traceable calibration kuti zvienderane nezvinodiwa neISO 9001 kana AS9100 audit.
KuZHHIMG, tinotenda kuti kunyatsorongeka hakufanirwe kuchengeterwa marabhoritari makuru ane nzvimbo isina muganho. Ndosaka tichipa mhando dzakasiyana dzemhinduro dzemapureti madiki akarongwa—imwe neimwe yakaedzwa yega yega, yakarongwa, uye yakabvumidzwa zvichienderana nezvinodiwa zvepasi rose. Tinoshanda pamwe chete nemaworkshop makuru anosanganisa matekiniki echinyakare ekubata nemaoko nekusimbisa kwemazuva ano kweinterferometric, tichiona kuti pureti yega yega inosangana negiredhi rayo rakatarwa. Uye nekuti tinonzwisisa kuti kuyera kuri kuenderera mberi, tinopa gwara pamusoro penguva dzekugadzirisa zvakare uye masevhisi ekutsigira kuchengetedza nzvimbo dzako dzekutarisa dzakavimbika kwemakore anotevera.
Nekuti pakupedzisira, metrology haisi yehukuru—inyaya yechokwadi. Ungave uchiyera banga re turbine kana micro-gear, data rako rakafanana nepamusoro paro. Usarega zviri nyore zvichikanganisa chivimbo. Mini surface plate yakachengetedzwa zvakanaka, inoshandiswa nezvishandiso zvekuyera granite zvakagadziriswa uye inotsigirwa ne surface table calibration yenguva dzose, haisi yeumbozha—ndiyo hwaro hwekuyera hunovimbika.
Saka zvibvunze kuti: kana ukanyatsoverenga zvakanyanya nhasi, unoziva here kuti pamusoro pako pakanyatsoti sandara—kana kuti uri kufungidzira? KuZHHIMG, tinokubatsira kutsiva kusava nechokwadi nekuva nechokwadi—micron imwe panguva.
