Hauv kev ntsuas qhov tseeb, lub phaj saum npoo ua haujlwm ua lub dav hlau siv los ntsuas qhov ntev - lub dav hlau tiag tiag uas siv rau txhua qhov kev ntsuas qhov ntev. Raws li cov kws ntsuas qhov ntev, cov kws tswj xyuas zoo, thiab cov chaw tsim khoom paub, kev xaiv cov khoom siv phaj saum npoo tuaj yeem cuam tshuam rau qhov tseeb ntawm kev ntsuas, kev ntseeg siab mus sij hawm ntev, thiab tag nrho cov nqi ntawm kev muaj.
Kev sib cav sib ceg ntawm cov phaj granite thiab cov hlau cam khwb cia tau txuas ntxiv mus rau ntau xyoo lawm, nrog rau cov lus sib cav txhawb nqa txhua yam khoom siv. Qhov kev sib piv no tshuaj xyuas qhov sib txawv tseem ceeb, qhov zoo, thiab cov ntawv thov los pab koj txiav txim siab zoo rau koj cov kev xav tau ntsuas qhov tseeb.
Keeb Kwm: Kev Hloov Pauv ntawm Cov Phaj Nto
Lub phaj nto precision muaj keeb kwm nplua nuj txij li thaum pib ntawm lub xyoo pua 19th. Henry Maudslay, tus kws ua vaj tse Askiv thawj coj, thawj zaug tsim cov txheej txheem scraping tes los tsim cov phaj hlau cam khwb cia uas tiaj tus heev, muab cov nto tseem ceeb rau kev ntsuas qhov tseeb thiab kev siv tshuab. Tom qab ntawd, Joseph Whitworth tau txhim kho thiab tshaj tawm txoj kev peb-phaj hauv xyoo 1840, tsim kom muaj cov txheej txheem tsim khoom uas ua rau muaj kev tsim khoom ntawm cov khoom sib pauv tau.
Yuav luag 150 xyoo, hlau cam khwb tau tswj hwm kev lag luam phaj nto. Txawm li cas los xij, thaum Tsov Rog Thoob Ntiaj Teb Zaum Ob, kev tsis txaus hlau tau tsav kev tsim kho tshiab. Wallace Herman thiab Donald V. Porter hauv Tebchaws Meskas tau pib sim nrog granite ua lwm yam khoom siv. Lawv txoj haujlwm, lees paub los ntawm kev tshawb nrhiav ntawm Crown Windley hauv UK, tau qhia tias granite muaj kev ruaj khov zoo dua, tiv taus kev hnav, thiab tiv taus xeb piv rau hlau.
Txij li xyoo 1940, granite tau maj mam dhau los ua cov khoom siv zoo tshaj plaws rau cov phaj nto, txawm hais tias cov hlau cam khwb cia tseem tseem muaj feem cuam tshuam rau cov ntawv thov tshwj xeeb. Niaj hnub no,granite nto phajtau dhau los ua tus qauv kev lag luam rau kev siv precision metrology thoob ntiaj teb.
Cov Phaj Nto Granite: Tus Txheej Txheem Niaj Hnub
Cov Txiaj Ntsig Tseem Ceeb
Kev Ruaj Ntseg Zoo Tshaj Plaws
