Sei marabhoritari epamusoro epasi achisarudza magadzirirwo egranite? Kuenzaniswa neiyo cast iron reference surface, iyo chaiyo kugadzikana yakagadziridzwa ne300%.

Mumarabhoritari epamusoro epasi rose, kungave kuri kucherechedzwa kwezvinhu zvenanoscale, kukwenenzverwa kwezvikamu zvemaziso chaiwo, kana kuyerwa kwe microstructure yema semiconductor machipisi, pane zvinenge zvakaomesesa zvinodiwa pakurongeka uye kugadzikana kwezviyero zvinongedzo. Granite straightedge, nekuita kwayo kwakatanhamara, yave sarudzo yekutanga kune akawanda marabhoritari. Kuenzaniswa neyechinyakare cast iron referensi nzvimbo, iko kugadzikana kwayo kunogona kuvandudzwa nekusvika 300%, iyo yakavakirwa pahumbowo hwakadzama hwesainzi uye humbowo hunoshanda. .
1. Zvinhu zvezvinhu zvinosarudza hwaro hwekururama
Cast iron, sechinyakare chinongedzo chepamusoro zvinhu, kunyangwe iine kumwe kuoma, ine hurema hwekuzvarwa. Iyo coefficient yekuwedzera kwekupisa inosvika 12 × 10⁻⁶/℃. Pasi peyakajairwa tembiricha yekuchinja kwemamiriro ekunze murabhoritari (senge 5 ℃ mutsauko wetembiricha unokonzerwa nekutanga uye kumira kwemaairconditioner), 1-mita-yakareba simbi yakakandwa referensi referensi inogona kuita shanduko ye60μm. Mukuwedzera, kune flake graphite zvimiro mukati mesimbi yakakandwa. Kushandiswa kwenguva refu kunowanzokonzera kushushikana kwepfungwa, zvichikonzera kuderera zvishoma nezvishoma mukupfava kwendege yereferensi. Rudzi urwu rwekupisa kwekupisa uye shanduko yezvimiro zvinokonzeresa kutsauka kwakarongeka mukuyera data, zvichikanganisa zvakanyanya kurongeka kwemhedzisiro yekuedza. .
Kusiyana neizvi, iyo coefficient yekuwedzera kwekushisa kwegranite straightedge ndeye (4-8) × 10⁻⁶/℃, iyo iri pasi pechetatu chesimbi yakakandwa. Pasi pemusiyano wakafanana wetembiricha we5 ℃, saizi shanduko ye1-mita-yakareba granite yakatwasuka ingori 20-40 μm. Granite inoumbwa nekristalllization yemaminerari akadai sequartz uye feldspar. Iine dense uye yunifomu chimiro uye hapana dambudziko remukati kushushikana kushushikana. Mushure memabhiriyoni emakore ema geological process, granite yave yakwegura uye haizokanganisika sesimbi yakakandwa nekufamba kwenguva, ichivimbisa kugadzikana kwenguva refu kweiyo ndege yereferensi kubva pachinhu chechinhu. .

Chechipiri, tekinoroji yekugadzira inowana yekupedzisira-yakanyanya kurongeka
Munguva yekugadziriswa kwesimbi yakakandwa referensi nzvimbo, nekuda kwekugumira kwezvinhu zvivakwa, iyo flatness kurongeka kazhinji inogona kungosvika ± 5-10 μm. Uyezve, pamusoro pesimbi yakakandwa inowanzoita oxidation uye ngura, inoda kugara ichigadziriswa uye kukuya. Kugaya kwega kwega kuchakanganisa kurongeka kwepakutanga kwereferensi. .
Granite straightedge inotora tekinoroji yekukuya-yakanyanya uye inosanganiswa neyepamusoro nhamba yekudzora kugadzirisa tekinoroji. Iyo flatness inogona kudzorwa mukati me ± 1-3 μm, uye zvimwe zvigadzirwa zvepamusoro zvinogona kutosvika ± 0.5μm. Kuoma kwayo kwepamusoro kunosvika 6 kusvika ku7 pachiyero cheMohs, uye kusagadzika kwayo ndeye 3 kusvika ku5 nguva yesimbi yakakandwa. Haikurumidzi kukwenywa kana kusakara. Kunyangwe mushure mekushandiswa kwenguva refu, iko kurongeka kwepamusoro kwegranite kutwasanuka kunogona kuramba kwakagadzikana, kubvisa kudiwa kwekugarogadzirisa uye kugadzirisa, zvichideredza zvakanyanya mutengo wekushandiswa kwerabhoritari uye mutengo wenguva. .
Iii. Kugadziriswa kwezvakatipoteredza kunovimbisa kuyerwa kwakagadzikana
Nzvimbo yerabhoritari yakaoma uye inoshanduka. Zvinhu zvakadai sehumidity, vibration uye electromagnetic interference zvinogona kukanganisa kuyera kwechiyero. Iyo cast iron reference surface inogara kuita ngura munzvimbo ine hunyoro, zvichikonzera kuwedzera kwekukasharara kwepamusoro uye kukanganisa kurongeka kweiyo yekuyeresa probe. Zvichakadaro, iyo magineti yesimbi yakakandwa inogona kukanganisa kushanda kweiyo chaiyo yemagetsi yekuyera michina. .
Granite straightedge isiri-metallic material, isiri-magnetic uye isina-conductive, uye haizokanganise zvigadzirwa zvemagetsi. Mvura yaro yekutora mvura iri pasi pe0.1%, uye inogona kuchengetedza kushanda kwakadzikama munzvimbo yakakwirira-yakanyorova. Uye zvakare, iyo yakasarudzika yekunyorovesa zvimiro zvegranite inogona kunyatso tora kudengenyeka kwezvakatipoteredza uye kuderedza kukanganiswa kwekunze. Semuyenzaniso, murabhoritari iri padhuze nemidziyo mikuru-zvikuru uye midziyo, girenati yakatwasuka inokwanisa kudzikisira pamusoro pe90% yesimba rekuzunguza mukati mesekondi imwe chete, nepo simbi yakakandwa inoreva nzvimbo inoda masekonzi matatu kusvika mashanu. Izvi zvinogonesa iyo granite kutwasanuka kuti ipe chirevo chakatsiga chekuyera kunyangwe munzvimbo dzakaoma. .
Four. Data chaiyo inosimbisa mabhenefiti ekuita
Iyo inozivikanwa pasi rose semiconductor marabhoritari yakamboita bvunzo yenguva refu yekuenzanisa pamusoro pesimbi yakakandwa uye granite referefeta nzvimbo: Panguva yekuyerwa kwakatora mazuva makumi matatu uye yakatora maawa masere zuva rega rega, iyo cumulative kuyerwa kukanganisa kwemidziyo uchishandisa iyo cast iron reference surface yakasvika ± 45μm. Midziyo inoshandisa granite straightedge ine chikanganiso chekuwedzera che ± 15μm chete, uye kuvandudzwa kwekugadzikana kwechokwadi kwakakwira se300%. Mimwe mibairo yekuedza yakafanana yakasimbiswa kakawanda mumarabhoritari epamusoro mundima dzakawanda senge zvinhu zvesainzi uye optical engineering, zvichiratidza kusadzoreredzwa kwegranite kutwasanuka mukuyera kwepamusoro. .
Mukupedzisa, iyo granite yakatwasuka yakapfuura zvakanyanyisa iyo yakakandwa simbi inonongedza pamusoro nekuda kweayo matatu mabhenefiti ezvivakwa zvezvinhu, kugadzira tekinoroji uye kuchinjika kwezvakatipoteredza. Yayo 300% kuvandudzwa mukugadzikana kwechokwadi haingopi yakavimbika kuyerwa bhenji kumarabhoritari asi zvakare inoisa hwaro hwakasimba hwekuvandudza kwekucheka-kumucheto kwesainzi tsvakiridzo uye chaiyo kugadzira tekinoroji. Ichi ndicho chaicho chikonzero chikuru chakaita kuti marabhoritari epamusoro epasi asarudze nzira dzakatwasuka dzegranite.
