Hauv kev ua haujlwm ntawm kev tsim khoom siv precision, kev ua tau zoo ntawm cov khoom siv kho qhov muag yog qhov tseem ceeb heev. Ib qho ntawm cov yam tseem ceeb uas ua rau nws ua tau zoo dua yog kev siv lub txaj granite. Cov qauv ruaj khov no muab lub hauv paus ruaj khov thiab txhim khu kev qha rau ntau yam khoom siv kho qhov muag, kom ntseeg tau tias lawv ua haujlwm tau zoo tshaj plaws.
Granite yog ib lub pob zeb ntuj uas paub txog nws qhov kev ruaj khov thiab kev ruaj khov, uas muaj ntau yam zoo dua li cov khoom siv ib txwm muaj xws li hlau lossis txhuas. Ib qho ntawm cov txiaj ntsig tseem ceeb yog nws lub peev xwm los txo qhov kev co. Cov khoom siv kho qhov muag feem ntau rhiab heev rau txawm tias qhov kev cuam tshuam me me, uas tuaj yeem ua rau kev ntsuas tsis raug lossis kev thaij duab. Cov txaj siv tshuab granite tuaj yeem nqus tau qhov kev co thiab tsim kom muaj ib puag ncig ruaj khov dua rau kev ua haujlwm zoo tshaj plaws ntawm cov kab ke kho qhov muag.
Tsis tas li ntawd xwb, qhov ruaj khov ntawm cov pob zeb granite yog lwm yam tseem ceeb. Cov khoom siv kho qhov muag raug rau qhov kub thiab txias hloov pauv, uas tuaj yeem ua rau cov ntaub ntawv nthuav dav lossis cog lus, ua rau tsis sib haum. Granite tswj nws cov qauv kev ua kom zoo thoob plaws ntau qhov kub thiab txias, ua kom ntseeg tau tias cov khoom siv kho qhov muag tseem sib haum, yog li txhim kho kev ua tau zoo tag nrho.
Qhov chaw tiav ntawm lub txaj granite tshuab kuj tseem ceeb heev. Granite qhov chaw du thiab ntuj tsim txo qhov kev sib txhuam thiab kev hnav, ua rau cov khoom siv kho qhov muag khiav tau zoo dua. Qhov no tseem ceeb heev rau cov ntawv thov xws li kev ua laser lossis kev thaij duab siab, qhov twg txawm tias qhov tsis zoo me me tuaj yeem ua rau muaj qhov yuam kev loj.
Tsis tas li ntawd xwb, cov txaj siv tshuab granite kuj tiv taus xeb thiab hnav tsis taus, ua rau lawv yog kev nqis peev mus sij hawm ntev rau cov chaw tsim khoom siv kho qhov muag. Cov txaj siv tshuab granite ruaj khov thiab tuaj yeem tiv taus kev siv txhua hnub yam tsis muaj kev cuam tshuam rau kev ua haujlwm.
Hauv ntej, lub txaj granite tshuab yog ib feem tseem ceeb ntawm kev txhim kho kev ua tau zoo ntawm cov khoom siv kho qhov muag. Lawv lub peev xwm los nqus kev poob siab, nyob ruaj khov thermally, muab ib qho chaw du thiab tiv taus kev hnav ua rau lawv zoo tagnrho rau kev siv precision. Raws li qhov kev thov rau cov kab ke kho qhov muag ua tau zoo txuas ntxiv mus, lub luag haujlwm ntawm granite tshuab txaj hauv kev lag luam yuav tsis ntseeg tau dhau los ua qhov tseem ceeb dua.
