Iko kudikanwa kwekudzikama kwedimensional mukuyera kwepamusoro-chaiyo ndeye mhedziso. Nepo granite ichirumbidzwa pasi rose nekuda kwekudzikama kwayo kwekupisa uye kudedera, mubvunzo wakajairika unomuka kubva kune mainjiniya munzvimbo dzine hunyoro: Hunyoro hunokanganisa sei chikuva chegranite?
Inyaya yekunetsekana, sezvo chero chinhu chinoshandiswa senge ndege yekutarisa ma micrometer kana maCMM anofanirwa kuramba pesvedzero yezvakatipoteredza. Mhinduro pfupi ndeiyi: nekuda kwechinhu chakanyatsosarudzwa uye kugadzirisa, yakakwirira-mhando yegranite inopikisa zvakanyanya kune hunyoro mhedzisiro.
Basa reKunyura Mvura Yakadzika muMetrology
Granite, sedombo rechisikigo, ine imwe nhanho yeporosity. Nekudaro, iwo chaiwo marudzi eblack granite anoshandiswa neZHHIMG kune metrology maapplication anosarudzwa chaizvo kune yavo dense, yakanaka-grained chimiro, izvo zvinotungamira kune kushoma kunyudzwa kwemvura.
Yakajairwa metrology-giredhi granite inowanzoisa mwero wekunyudzwa kwemvura pazasi 0.13% (mazhinji emhando dzeprimiyamu dzakatodzika, kazhinji dziri pedyo ne0.07% kana pasi). Hunhu uhu hwakakosha pakuchengetedza chokwadi kwenguva refu:
- Kuderedza Kuwedzera kweHygroscopic: Nepo zvimwe zvinhu zvichigona kuzvimba kana kubatirana zvakanyanya sezvo zvichitora kana kuburitsa hunyoro (hygroscopic expansion), iyo yakanyanya kuderera porosity yechaiyo giraniti inodzikamisa izvi zvakanyanya. Huwandu hwemvura inotorwa nedombo hahuna basa, kudzivirira chero shanduko yakakosha inogona kukanganisa kutaridzika kwendege.
- Dziviriro Pakupokana NeNgura: Zvichida mukana unoshanda kudzivirirwa kwainopa maturusi ako anokosha. Kana ndiro yepamusoro iine porosity yakakwirira, yaizochengeta hunyoro pedyo nepamusoro. Unyoro uhu hunogona kukonzera ngura uye ngura pamageji esimbi, zvishongedzo, uye zvinhu zvakaiswa pagranite, zvichitungamira mukupfeka nguva isati yakwana uye zviyero zvakasvibiswa. Iyo yakaderera porosity yeBlack Granite Components yedu inoderedza njodzi iyi, ichitsigira nharaunda isina ngura.
Humidity vs. Kururama: Kunzwisisa Kutyisidzira chaiko
Nepo granite pachayo ichiramba deformation kubva mumhepo yemhepo, isu tinofanirwa kujekesa mutsauko uripo pakati pekugadzikana kwechinhu uye kutonga kwezvakatipoteredza mune chaiyo lab:
| Factor | Yakananga Mhedzisiro paGranite Platform | Indirect Effect paMeasurement System |
| Mvura Yekunyura Mwero | Neggible dimensional shanduko (yakaderera porosity) | Yakaderedzwa njodzi ye ngura pane accessories uye geji. |
| Ambient Humidity (Kumusoro) | Negligible deformation yegranite slab pachayo. | Zvinokosha: Kuwedzera njodzi yekumisikidza pamidziyo yekuyeresa simbi, inogona kukanganisa CMM calibration uye kuverenga kwemaziso. |
| Ambient Humidity (Yakaderera) | Kuchinja kusingakodzeri kune granite slab. | Kuwedzera static magetsi, kukwezva ma micro-particles anokonzera kupfeka uye flatness nyaya. |
Senyanzvi muUltra-Precision Platforms, tinokurudzira kuti vatengi vachengetedze nharaunda inodzorwa nehunyoro, zviri pakati pe50% ne60% Relative Humidity (RH). Kudzora uku kushoma nezvekudzivirira giraniti slab uye zvimwe nezve kuchengetedza iyo yese metrology system (CMMs, geji, optics) uye nekuona kugadzikana kwekupisa kwemhepo pachayo.
ZHHIMG's Guarantee ye Enduring Stability
Iyo granite yatinosarudza — ine mukurumbira nekuwanda kwayo uye zviyo zvakatsetseka — inopa hwaro hwakatsiga hunopesana nekuchinja kwemafuta nekunyorova. Kuzvipira kwedu pakushandisa granite ine yakakwirira chaiyo giravhiti inovimbisa kuti iwe unogashira yakasimba, isingaore-inodzivirira tafura yekuongorora iyo inochengetedza kudzikama kwayo kwepakutanga uye kutendeseka kwemakumi emakore, ichida chete yakajairwa nyanzvi kudzokororwa nekuda kwekupfeka, kwete kukanganiswa kwezvakatipoteredza.
Paunodyara mari muZHHIMG Precision Granite base, iwe urikudyara munheyo yakagadzirirwa kuomarara kwechero nzvimbo yekuyeresa yekuyera.
