Unoda Nanometer Kururama? Nei Gauge Mabhuraki ari Mambo weMetrology

Munzvimbo inoyerwa kureba mumamiriyoni emainji uye nemazvo ndiyo chete mwero — nharaunda inodiwa yakafanana inofambisa kugadzirwa kweZHHIMG® kune chishandiso chimwe chinotonga zvakanyanya: Gauge Block. Anozivikanwa pasi rose seJo Blocks (mushure memuvambi wavo), mageji anotsvedza, kana mabhuroko eHoke, aya akatsetseka uye akakwenenzverwa simbi kana zvimedu zveceramic ndiwo musimboti wezvese dimensional metrology. Hazvisi zvokushandisa chete; iwo ndiwo mufananidzo chaiwo wehurefu hwakati, hunoshanda seyekupedzisira referensi poindi yekuenzanisa zvese kubva kuma micrometer uye macalipers kusvika kune sine mabara uye dial zviratidzo mukati mese makuru maindasitiri.

Shanduko muChiyero: Nhoroondo yeJo Block

Gore ra1896 risati rasvika, mashopu emuchina aivimba nebespoke, maturusi ekuyeresa akasarudzika-mageji akajairwa-akajairwa uye macheki e "Go/No-Go". Ichiri kushanda, sisitimu iyi yakashaya chinhu chakakosha chekumisikidzwa kwepasirese.

Mafungiro ekuchinja mutambo akaunzwa nemuchina wekuSwedish akangwara Carl Edvard Johansson muna 1896. Pfungwa yechimurenga yaJohansson yaive yekugadzira zviyero zvehurefu zvemunhu mumwe nemumwe, izvo zvaigona kurongedzerwa pamwechete zvisina musono. Utsva uhwu hwaireva kuti tumabhuroko twakagadzirwa zvine hungwaru twaigona kubatanidzwa kuti riwane zviuru zvehurefu hwakasiyana, hwakarurama zvikuru—kushanduka kwaisati kwambonzwika. Mabhuroko egeji aJohansson akamisa kureba kwereferensi yenyika yemaindasitiri.

Mashiripiti ekunamatira: Kunzwisisa "Wringing"

Chinhu chinonyanya kushamisa chegeji block kugona kwayo kunamatira zvakasimba kune imwe bhuroka ine kushoma dimensional kukanganisa. Chiitiko ichi chinonzi wringing. Inowanikwa nekutsvedza mabhuroko maviri pamwechete, zvichiita kuti nzvimbo dzawo dzisingaoneki dzibatane kuti dzibatane zvakachengeteka, zvichibvisa chero gaka remhepo uye kuderedza mupiro wejoinhi mukukanganisa kwese.

Ichi chakasarudzika chivakwa ndicho chinopa geji inovhara yavo inoshamisa yekushandisa. Semuenzaniso, nekushandisa mabhuroki matatu chete kubva pane yakajairwa seti, munhu anogona kuwana churu chakasiyana kureba-ti, kubva 3.000 mm kusvika 3.999 mm mu 0.001 mm increments. Iyo yakadzama engineering trick inoita kuti ive yakakosha.

Matanho mana eKunyatso Wringing

Kuwana iyi chaiyo chisungo inyanzvi, nhanho ina hunyanzvi:

1. Kuchenesa Kwekutanga: Tanga nekupukuta zvinyoro zvidhinha padhidhi ine mafuta.
2. Kubvisa Oiri: Tevere, pukuta zvivharo padhi yakaoma kuti ubvise chero mafuta akawandisa, uchisiya chete firimu remicroscopic.
3. Muchinjikwa Maumbirwo: Isa bhuroko rimwechete perpendicularly mhiri kwerimwe uye shandisa zvine mwero kudzvanya uchizvitsvedza pamwe chete kusvika vagadzira muchinjikwa.
4. Kurongeka: Pakupedzisira, tenderedza zvidhinha kusvika zvanyatsoenderana, uchiavharira mudura rakasimba, repamusoro-soro.

Iyi nzira yekungwarira inosimbisa kukosha kwehutsanana, kudzorwa kudzvanywa, uye kurongeka chaiko kuti uwane kuchengetedzeka uye kwakaringana kubatana kunodiwa pabasa remetroloji. Kubudirira kwekunamatira uku kunotsanangurwa zviri pamutemo se "wringability," iyo inoda kupera kwepamusoro kwe 1 microinch 0.025 μm m) AA kana zvirinani, uye kutsetseka kweinenge 5 μin (0.13 μm).

Maitiro Akanakisisa: Kuchengetedza Hurefu Hwako Maitiro

Nekuda kwekunyanya kurongeka, magauge mabhuroko anoda kungwarira mukubata nekuchengetedza. Nyanzvi dzinonzwisisa kuti kurebesa uye kurongeka kweseti kunoenderana zvachose nekuomerera kune akanakisa maitiro:

• Kudzivirirwa kweCorrosion: Pakarepo mushure mekushandisa, zvidhinha zvinofanirwa kuzorwazve mafuta kana kuzorwa girizi. Corrosion ndiye muvengi wekutanga wekugadzikana kwedimensional, uye kuregeredza nhanho iyi kuchakurumidza kuparadza kurongeka kwepamusoro.
• Kubata: Gara uchibata zvivharo pamativi awo, usambobata nzvimbo dzakakosha dzekuyeresa. Kupisa kwemuviri uye mafuta eganda anoendesa kune block, zvichikonzera kuwedzera kwechinguvana uye nekuora zvachose nekufamba kwenguva.
• Kudzora Tembiricha: Zvigero zvegeji ndizvo chaizvo kana zvichiyerwa patembiricha inotsanangurwa pasi rese ye20 ℃ (68°F). Chero kuyerwa kunoitwa kunze kweiyi nharaunda inodzorwa kunoda muripo wekupisa.

Mhedziso: Iyo Precision ZHHIMG® Inovaka Pairi

Mageji mabhuraki ndiwo magamba asina kusiiwa anosimbisa nyika yekugadzira chaiyo. Ndiwo nzvimbo isingachinjiki yereferensi iyo ZHHIMG® inoyera maturusi ayo ekuyeresa epamberi, kuve nechokwadi chekuti granite yedu, ceramic, uye simbi zvikamu zvinowana micrometer uye nanometer kushivirira kunodiwa kumichina yepamberi yepasirese. Nekuremekedza nhoroondo uye nekuomerera kune akanakisa maitiro ezvishandiso zvakakosha izvi, isu pamwe chete tinosimudzira mwero wekurongeka unofambisa kufambira mberi kwetekinoroji.
