Cov txheej txheem tsim khoom rau Natural Granite Bases

Kev tsim cov siab -precision granite hauv paus pib nrog sawing ib lub pob zeb granite rau qhov ntev uas yuav tsum tau siv lub pob zeb diamond ncig pom hniav, ua raws li los ntawm ntau theem ntawm kev sib tsoo nrog lub log abrasive; pob zeb diamond core khoom siv rau txhua qhov tsim nyog drilling. Kev sib tsoo zaum kawg yog ua los ntawm cov cuab yeej grey cam khwb cia hlau lapping thiab silicon carbide abrasive, ib txoj haujlwm ua los ntawm cov kws tshaj lij tshaj plaws. Cov khoom lag luam zoo raug txheeb xyuas los ntawm kev siv hluav taws xob profileometers, autocollimators, thiab laser ntsuas tshuab. Cov qauv kev ua tau zoo yuav tsum muaj kev sib haum xeeb ntawm qhov tsis muaj ntau tshaj 4 μm tshaj 1m × 1m cheeb tsam thiab qhov tseeb qhov tseeb hauv ± 0.2 arcseconds. Ua tib zoo xaiv ntawm sawing tsis yog qhov tseem ceeb thaum txiav granite nrog pob zeb diamond ncig hniav. Thaum siv cov hniav tshiab, nws raug nquahu kom ua ntej txiav cov pob zeb silicate los yog cov ntaub ntawv zoo sib xws uas siv cov txiav txiav kom zoo kom nthuav tawm cov pob zeb diamond txiav npoo (hnav khaub ncaws). Kev khiav hauj lwm tsis muaj xws li peripheral hniav ceev ntawm 25-30 m / s, pub tus nqi ntawm 0.4-1.0 m / min, thiab txiav qhov tob ntawm 25-40 mm. Lub pob zeb diamond hniav siv ntau yam ntawm 320 mus rau 1250 mm nyob rau hauv txoj kab uas hla nrog ntu thicknesses ntawm 3.1–7.0 hli; lawv siv cov pob zeb hluavtaws sib npaug (50/40 mesh) thiab tooj liab -nickel alloy daim ntawv cog lus. Cov ntu yog brazed mus rau cov hlau hniav core siv nyiaj solder nyob rau hauv ib tug siab - zaus furnace ntawm 650℃.
Nws yuav tsum tau muab sau tseg tias tsis yog tag nrho cov granite ntau yam yog haum rau lub hauv paus ntawm xws li high - precision ntsuas ntsuas; granite nrog ib tug nplua -cov qauv nplej thiab cov coefficient qis ntawm linear thermal expansion yog qhov kev xaiv.
