Baro heerka saamaynta isbedbedelka heerkulka jawiga ee saxnaanta cabbiraadda saxda ah ee granite.

Goobta cabbirka saxda ah, madal sax ah oo granite ah oo leh xasilloonideeda ugu wanaagsan, adkaanta sare iyo iska caabbinta xirashada wanaagsan, ayaa noqotay taageerada aasaasiga ah ee ugu habboon ee shaqo cabbirro badan oo sax ah. Si kastaba ha ahaatee, isbedbedelka heerkulka ee arrimaha deegaanka, sida "dilaha saxda ah" ee ku qarsoon mugdiga, waxay leeyihiin saameyn aan la taaban karin oo ku saabsan saxnaanta cabbirka saxda ah ee granite. Waa muhiim in si qoto dheer loo baaro heerka saamaynta si loo hubiyo saxnaanta iyo isku halaynta shaqada cabbirka.

Inkasta oo granite loo yaqaan xasilloonida, kama difaaco isbeddelka heerkulka. Qaybaheeda ugu muhiimsan waa quartz, feldspar iyo macdano kale, kuwaas oo soo saari doona fidinta kulaylka iyo ifafaale heerkul kala duwan. Marka heerkulka deegaanku kor u kaco, goobta saxda ah ee granite waa la kululeeyaa oo la ballaariyaa, xajmiga goobta ayaa isbeddeli doona wax yar. Marka heerkulku hoos u dhaco, waxay dib ugu soo laaban doontaa sidii hore. Isbeddellada cabbirkoodu yar yahay ayaa lagu weynayn karaa arrimo muhiim ah oo saameeya natiijooyinka cabbirka xaaladaha cabbirka saxda ah.

Qaadashada qalabka cabbiraadda isku-xidhka guud ee ku habboon madal granite tusaale ahaan, hawsha cabbirka saxda ah ee saxda ah, shuruudaha saxnaanta cabbirka waxay inta badan gaadhaan heerka micron ama xitaa ka sarreeya. Waxaa loo maleynayaa in heerkulka caadiga ah ee 20 ℃, cabbirrada cabbirka kala duwan ee madalku ay ku jiraan xaalad ku habboon, iyo xog sax ah ayaa laga heli karaa iyadoo la cabbirayo workpiece. Marka heerkulka deegaanku is beddelo, xaaladdu aad bay uga duwan tahay. Ka dib tiro badan oo xogta tijaabada ah iyo falanqaynta aragtida, xaaladaha caadiga ah, isbedbedelka heerkulka deegaanka ee 1℃, ballaarinta toosan ama foosha ee goobta saxda ah ee granite waxay ku saabsan tahay 5-7 × 10⁻⁶/℃. Tani waxay ka dhigan tahay in mashiinka granite ee leh dhererka dhinaca ee mitirka 1, dhererka dhinaca ayaa laga yaabaa inuu isbeddelo 5-7 microns haddii heerkulku isbeddelo 1 ° C. Qiyaasta saxda ah, isbeddelka cabbirka ayaa ku filan inuu keeno khaladaadka cabbirka ee ka baxsan xadka la aqbali karo.
Shaqada cabbiraadda ee looga baahan yahay heerarka saxda ah ee kala duwan, heerka saameynta isbeddelka heerkulka ayaa sidoo kale ka duwan. Qiyaasta saxda ah ee caadiga ah, sida cabbirka cabbirka qaybaha farsamada, haddii qaladka cabbiraadda la oggol yahay uu ku jiro ± 20 microns, marka loo eego xisaabinta isugeynta balaadhinta ee kor ku xusan, isbeddelka heerkulka wuxuu u baahan yahay in lagu xakameeyo inta u dhaxaysa ± 3-4 ℃, si loo xakameeyo qaladka cabbirka ee uu keeno isbeddelka cabbirka madal ee heer la aqbali karo. Meelaha leh shuruudaha saxda ah ee saxda ah, sida cabbiraadda habka lithography ee wax soo saarka semiconductor chip, qaladka waxaa loo ogol yahay gudaha ± 1 micron, iyo isbedbeddelka heerkulka ayaa u baahan in si adag loo xakameeyo gudaha ± 0.1-0.2 ° C. Marka heerkulka isbedbedelku uu dhaafo heerkan, balaadhinta kulaylka iyo foosha ee cabbirka granite waxay keeni kartaa wax-soo-saarka.
Si loola tacaalo saameynta isbeddelka heerkulka jawiga ee cabbiraadda saxda ah ee saxda ah ee granite, tallaabooyin badan ayaa inta badan lagu qaataa shaqo la taaban karo. Tusaale ahaan, qalabka heerkulka joogtada ah ee saxda ah ayaa lagu rakibay deegaanka cabbirka si loo xakameeyo isbeddelka heerkulka ee kala duwanaansho aad u yar; Magdhawga heerkulka waxaa lagu fuliyaa xogta cabbirka, natiijooyinka cabbirana waxaa lagu saxaa algorithm software iyadoo loo eegayo isku-dhafka fidinta kulaylka ee goobta iyo isbeddellada heerkulka waqtiga-dhabta ah. Si kastaba ha noqotee, iyada oo aan loo eegin tallaabooyinka la qaadayo, fahamka saxda ah ee saameynta isbeddelka heerkulka jawiga ee saxnaanta cabbirka saxda ah ee granite waa aasaaska hubinta shaqada cabbirka saxda ah oo la isku halleyn karo.
