Cov Cheebtsam Granite Uas Muaj Kev Ntsuas Zoo — Kev Tsim Khoom Granite Uas Muaj Kev Ntsuas Zoo Rau Cov Khoom Siv Uas Muaj Kev Ntsuas Zoo Tshaj Plaws

Tsis yog txhua lub granite siv tau rau kev ua cov qauv zoo. Cov granite siv rau hauv cov khoom siv zoo yog cov granite dub uas muaj cov minerals ntau - feem ntau nyob ib ncig ntawm 3,100 kg / m³ - uas muab:

Kev ruaj khov ntawm qhov ntev thoob plaws qhov kub thiab txias: Tus coefficient ntawm thermal expansion rau cov granite dub zoo yog kwv yees li 5 × 10⁻⁶/°C, txhais tau tias ib feem ib 'meter' hloov qhov ntev tsuas yog 5 micrometers ib degree Celsius. Piv qhov no rau txhuas ntawm 23 × 10⁻⁶/°C lossis hlau ntawm 12 × 10⁻⁶/°C - granite yog kwv yees li plaub npaug ntau dua thermally ruaj khov dua li hlau thiab yuav luag tsib npaug ntau dua li txhuas.

Kev co zoo dua: Granite dissipates lub zog co zoo dua li hlau lossis txhuas. Qhov no yog qhov tseem ceeb rau cov khoom siv ua qhov ntsuas lossis cov txheej txheem uas xav tau lub sijhawm sib koom ua ke ntev - kev tshuaj xyuas qhov muag, kev ntsuas scanning, lossis txhua lub kaw lus uas cov duab lossis cov teeb liab meej tseem ceeb.

Tsis muaj kev pheej hmoo ntawm kev xeb: Tsis zoo li cov hlau cam khwb cia, uas xav tau cov txheej tiv thaiv kom tsis txhob xeb, granite tsis nkag tau rau hauv huab cua noo thiab feem ntau cov tshuaj lom neeg hauv kev lag luam. Tsis muaj txheej txheej kom lwj, tsis muaj xeb kom ntxuav, tsis muaj kev hloov pauv loj vim yog xeb dhau ntau xyoo ntawm kev pabcuam.

Cov khoom siv sib xws: Cov khoom sib xyaw ua ke ntawm cov pob zeb granite dub zoo yog homogeneous - tsis muaj ciam teb ntawm cov noob, kev sib cais, lossis kev ntxhov siab sab hauv kom ua rau muaj kev hloov pauv tsis tau xav txog. Ib feem ntawm granite ua haujlwm tau kwv yees vim nws cov khoom siv zoo ib yam.

Kev hnav tsis kam: Granite nyuaj dua li feem ntau cov hlau, txhais tau tias cov yam ntxwv ntawm kev teeb tsa, cov chaw siv, thiab cov kev coj ua kom lawv cov geometry nyob ntev dua yam tsis muaj kev hnav ntsuas tau.

Muaj ib txhia neeg muag khoom hloov cov granite uas tsis zoo lossis marble kom txo nqi. Marble muaj qhov ceev qis dua (feem ntau yog 2,500–2,700 kg/m³), thermal expansion siab dua, thiab yuav tsis tswj tau qhov geometry tseeb dhau sijhawm. ZHHIMG tsuas yog siv cov granite dub uas muaj qhov ceev siab uas tau txheeb xyuas - peb muab daim ntawv pov thawj khoom siv uas lees paub qhov ceev thiab cov khoom sib xyaw thaum thov.

Kev Cai Granite Casting: Los ntawm Kev Tsim Qauv mus rau Qhov Tiav

Kev tsim cov khoom siv granite precision yog ib qho txheej txheem ntau theem uas muab cov ntsiab cai ntawm kev casting hlau nrog kev ua haujlwm pob zeb precision:

Kev xaiv thiab kev npaj cov khoom siv: Cov pob zeb granite nyoos raug tshuaj xyuas seb puas muaj qhov tawg sab hauv, puas sib npaug ntawm cov minerals, thiab puas ceev. Tsuas yog cov khoom siv uas ua tau raws li peb qhov kev qhia ceev (>3,000 kg/m³) thiaj li yuav tsim tau.

Kev ua kom ntxhib: Lub pob zeb granite raug tsim kom ze li qhov loj kawg siv cov cuab yeej txiav pob zeb diamond thiab cov cuab yeej sib tsoo ntxhib. Nyob rau theem no, kev tshem tawm cov khoom siv yog qhov hnyav - feem ntau tshem tawm 5-20 hli ib zaug ua haujlwm.

Kev sib tsoo kom raug: Cov tshuab sib tsoo CNC ntau lub axis nrog lub log pob zeb diamond lossis CBN coj cov khoom mus rau qhov loj kawg. Rau cov khoom loj, cov tshuab sib tsoo loj tshwj xeeb tswj tau qhov sib npaug zoo dua 1 μm / m thoob plaws qhov chaw ua haujlwm tag nrho.

Kev ua tiav nta: Cov platforms tsa, cov ntug datum, cov qhov nta, thiab cov nto mounting tau txais kev ua haujlwm precision thib ob - feem ntau yog tes ua tiav los ntawm cov kws ua tes ua haujlwm nrog ntau xyoo ntawm kev paub - kom ua tiav qhov kev kam rau siab uas xav tau ntawm cov yam ntxwv ua haujlwm.

Kev txheeb xyuas qhov zoo: Txhua qhov tseem ceeb yog ntsuas siv cov tshuab ntsuas sib koom ua ke, laser interferometers, lossis cov theem hluav taws xob nrog qhov kev daws teeb meem sub-micron. Txhua yam khoom siv ntsuas tau raug ntsuas raws li cov qauv ntsuas hauv tebchaws.
