Isidingo sozinzo lwe-dimensional kumlinganiselo ophezulu wokuchaneka ngokuqinisekileyo. Ngelixa i-granite inconywa kwihlabathi jikelele ngokuzinza kwayo kwe-thermal kunye ne-vibration damping, umbuzo oqhelekileyo uvela kwiinjineli kwiindawo ezifumileyo: Ngaba ukufuma kuchaphazela njani iqonga legranite elichanekileyo?
Yinkxalabo esebenzayo, njengoko nayiphi na imathiriyeli esetyenziswa njengenqwelo-moya yesalathiso kwii-micrometers okanye ii-CMM kufuneka ixhathise impembelelo yokusingqongileyo. Impendulo emfutshane yile: ngenxa yezinto ezikhethwe ngononophelo kunye nokucutshungulwa, i-granite echanekileyo yomgangatho ophezulu iyamelana kakhulu nemiphumo yokufuma.
Indima yokufunxwa kwamanzi aphantsi kwiMetrology
I-Granite, njengelitye lendalo, inalo inqanaba elithile le-porosity. Nangona kunjalo, iintlobo ezithile zegranite emnyama esetyenziswa yi-ZHHIMG kwizicelo ze-metrology zikhethwa ngokuchanekileyo ngenxa yesakhiwo sazo esixineneyo, esicolekileyo, esikhokelela kwisantya esincinci sokufunxa kwamanzi.
Igranite yenqanaba le-metrology eqhelekileyo idla ngokuba nezinga lokufunxa kwamanzi ngaphantsi kwe-0.13% (iintlobo ezininzi zeprimiyamu zingaphantsi nangakumbi, zihlala zisondele kwi-0.07% okanye ngaphantsi). Olu phawu lubalulekile ekugcineni ukuchaneka kwethuba elide:
- Ukunciphisa Ukwandiswa kweHygroscopic: Ngelixa ezinye izixhobo zinokudumba okanye zinciphe kakhulu njengoko zifunxa okanye zikhulula ukufuma (ukwandiswa kwehygroscopic), iporosity ephantsi kakhulu yegranite echanekileyo iyasida kakhulu esi siphumo. Ubungakanani bamanzi afunxwe lilitye alinamsebenzi, kuthintela naluphi na utshintsho olubalulekileyo olunokuthi luchaphazele ukuthambeka kwenqwelomoya yereferensi.
- Ukukhuselwa Kumhlwa: Mhlawumbi uncedo olusebenzisekayo ngakumbi lukhuselo olunika izixhobo zakho ezixabisekileyo. Ukuba ipleyiti yomphezulu ine-porosity ephezulu, iyakugcina ukufuma kufutshane nomphezulu. Oku kufuma kunokubangela i-corrosion kunye ne-rust kwi-metal gauges, i-accessories, kunye namacandelo abekwe kwi-granite, ekhokelela ekugqokeni kwangaphambili kunye nemilinganiselo engcolileyo. I-porosity ephantsi ye-Black Granite Components zethu zinciphisa lo mngcipheko, ukuxhasa indawo engenamhlwa.
Ukufuma vs. Ukuchaneka: Ukuqonda Ingozi yokwenyani
Ngelixa i-granite ngokwayo imelana nokuguqulwa komgangatho ukusuka kumswakama we-atmospheric, kufuneka sicacise umahluko phakathi kozinzo lwemathiriyeli kunye nolawulo lokusingqongileyo kwilebhu echanekileyo:
| Umba | Isiphumo esithe ngqo kwiPlatform yeGranite | Impembelelo engathanga ngqo kwiNkqubo yoMlinganiselo |
| Izinga lokufunxa kwamanzi | Utshintsho lwe-dimensional engafanelekanga (i-porosity ephantsi) | Umngcipheko oncitshisiweyo womhlwa kwizincedisi kunye neegeyiji. |
| Ukufuma kwe-Ambient (Phezulu) | I-deformation engafanelekanga ye-granite slab ngokwayo. | Okubalulekileyo: Umngcipheko wokunyuka kwe-condensation kwizixhobo zokulinganisa isinyithi, ezinokuchaphazela ukulinganisa kwe-CMM kunye nokufundwa kwe-optical. |
| Ukufuma kwe-Ambient (Phantsi) | Utshintsho olungenamsebenzi kwi-slab yegranite. | Ukonyuka kombane ongatshintshiyo, ukutsala amasuntswana amancinci abangela imiba yokunxiba kunye ne-flatness. |
Njengeengcali kwi-Ultra-Precision Platforms, sincoma ukuba abathengi bagcine indawo elawulwa ngumswakama, ngokufanelekileyo phakathi kwe-50% kunye ne-60% ye-Humidity Relative (RH). Olu lawulo luncinci malunga nokukhusela i-granite slab kunye nokunye malunga nokukhusela yonke inkqubo ye-metrology (i-CMMs, i-gauges, i-optics) kunye nokuqinisekisa ukuzinza kwe-thermal yomoya ngokwawo.
IsiQinisekiso se-ZHHIMG soZinzo oluZinzileyo
Igranite esiyikhethayo-eyaziwa ngokuxinana kwayo okuphezulu kunye nokutya okuziinkozo okucolekileyo-inika isiseko esizinzileyo ngokuchasene nokuguquguquka kwe-thermal nokufuma. Ukuzibophelela kwethu ekusebenziseni igraniti enobunzima obukhethekileyo obuphezulu kuqinisekisa ukuba ufumana itheyibhile yokuhlola ehlala ixesha elide, ekwaziyo ukumelana nomhlwa eya kuthi igcine ukuthe tyaba kwayo kwasekuqaleni kunye nemfezeko kangangamashumi eminyaka, ifuna kuphela uhlengahlengiso olusemgangathweni ngenxa yokuguga, hayi ukonakala kwendalo.
Xa utyala imali kwisiseko se-ZHHIMG Precision Granite, utyala imali kwisiseko esenzelwe ukuqina kwayo nayiphi na imeko yokulinganisa ukunyamezela okuphezulu.
