Chifukwa Chake Zipangizo Zolondola Kwambiri Zimafunikira Granite, Osati Marble

Ngati mukufotokoza maziko, nsanja, kapena chida choyezera cha makina olondola — CMM, laser system, semiconductor tool, kapena coordinate measurement device — mwina mwawonapo "granite" ndi "marble" zomwe zimaperekedwa ndi ogulitsa, nthawi zina pamitengo yosiyana kwambiri. Miyala iwiriyi ingawoneke ngati diso losaphunzitsidwa, koma pakugwiritsa ntchito molondola sikusinthana. Kusankha yolakwika kungawononge pang'onopang'ono kulondola ndi moyo wa makina opangidwa bwino.

Nkhaniyi ikufotokoza kusiyana kwenikweni pakati pa granite ndi marble, chifukwa chake kusiyana kumeneku n'kofunika pa ntchito yolondola, komanso zomwe muyenera kuyang'anira pamene "granite" ya wogulitsa siili yomwe ikunena.

1. Kuchulukana ndi Kukhazikika kwa Misa

Kuchulukana kwa miyala kumakhudza mwachindunji momwe maziko a miyala amatsukira kugwedezeka, kupatuka, ndi kugwedezeka kwa nthawi yayitali pansi pa katundu.

• • Granite ndi mwala wa igneous wopangidwa kuchokera ku magma yozizira pang'onopang'ono, zomwe zimapangitsa kuti ukhale wolimba, wolumikizana bwino. Granite wakuda wapamwamba nthawi zambiri amafika pamlingo wa 2,900–3,100 kg/m³, wokhala ndi magwero apamwamba - monga granite wakuda ZHHIMG® yomwe imasankha chifukwa cha maziko ake olondola - yolemera ≈3,100 kg/m³, poyerekeza kapena kupitirira magwero ambiri odziwika bwino a granite aku Europe ndi North America.
• • Marble ndi mwala wosinthika (mwala wa limestone wopangidwanso), nthawi zambiri umakhala wofewa komanso wosakhuthala, nthawi zambiri umakhala pakati pa 2,600–2,750 kg/m³. Kapangidwe kake kamakhala ndi mabowo ambiri ndipo sikakhazikika bwino pakapita nthawi.

Kuchuluka kwa mphamvu kumatanthauza kulemera kolemera komanso kochulukira kwa malo omwewo - zomwe zimapangitsa kuti kugwedezeka kwabwino kukhale kochepetsetsa komanso nsanja yopanda mphamvu yoyezera mulingo wa micron.

2. Kuuma ndi Kukana Kuvala

Pa muyeso wa kuuma kwa Mohs, granite nthawi zambiri imakhala ndi ma 6-7, pomwe marble imakhala yotsika pafupifupi 3-4. Mwachidule:

• • Granite imakana kukanda, kuwonongeka kwa pamwamba, ndi kusweka chifukwa cha kukhudzana mobwerezabwereza kwa zida, kukhudza kwa probe, kapena kugwira ntchito ndi zinthu zina.
• • Marble ndi yofewa kwambiri, zomwe zikutanthauza kuti imawonongeka mwachangu ikagwiritsidwa ntchito mofananamo — vuto lenileni la mbale zapamwamba ndi zida zoyezera zomwe zimakhudzidwa, kufufuzidwa, kapena kutsetsereka tsiku ndi tsiku.

Malo ofewa samakhala osalala. Pakatha miyezi yambiri akugwiritsidwa ntchito, nsanja ya marble imatha kupanga mapangidwe oyeretsedwa bwino komwe imagwiritsidwa ntchito kwambiri - zomwe ndi zosiyana ndi zomwe malo owunikira molondola amafunikira.

3. Kukhazikika kwa Kutentha

Kuyeza molondola kumakhala kovuta kwambiri pakukula kwa kutentha, chifukwa ngakhale gawo laling'ono la kusintha kwa kutentha limatha kusintha miyeso pamlingo wa micron.

• • Granite ili ndi kuchuluka kochepa komanso kofanana kwa kutentha, ndipo kapangidwe kake kokhuthala komanso kotsika ka ma porosity kumatanthauza kuti imayankha pang'onopang'ono komanso modziwikiratu kusintha kwa kutentha kwa mlengalenga - momwemonso momwe mumafunira m'chipinda choyezera kutentha chomwe chimayendetsedwa ndi kutentha.
• • Marble, pokhala ndi mabowo ambiri komanso yogwira ntchito ndi mankhwala (monga mwala wochokera ku calcium carbonate), nthawi zambiri imayamwa chinyezi ndipo imayankha mosadziwika bwino ku chinyezi ndi kusintha kwa kutentha, komwe kungayambitse kusuntha pang'ono koma kwenikweni pakapita nthawi.

Ichi ndi chimodzi mwa zifukwa zomwe granite ndi chinthu chodziwika bwino m'ma lab a metrology, ma semiconductor fabs, ndi zipinda zoyezera padziko lonse lapansi - pomwe marble siili.

4. Kukana Mankhwala

Marble imayamwa ndi asidi wofatsa (ngakhale khofi, zotsukira, kapena zotsalira za zoziziritsira zimatha kuwononga pamwamba pake), ndichifukwa chake nthawi zambiri zimakhala zachilendo kuwona malo osungira marble akupanga malo osawoneka bwino pakapita nthawi. M'malo opangira mafakitale kapena ochitira labu komwe kuli zoziziritsira, madzi odulira, kapena mankhwala oyeretsera, kukhudzidwa kwa mankhwala kumeneku kumakhala vuto lalikulu kwamalo oyezeraGranite ndi yopanda mankhwala ndipo imatha kupirira madera a mafakitale popanda kuwonongeka kwambiri.

5. Chifukwa Chake Izi Ndi Zofunika pa Zida Zanu

Izi si mawu apansi panthaka a sayansi ya zinthu zakuthupi — zimakhudza mwachindunji:

• • Zipangizo za semiconductor, ma CMM, ndi zida zoyezera zogwirizanitsa, komwe kukhazikika kwa maziko kumatsimikizira ngati kubwerezabwereza kwa muyeso wanu kudzakhalapo kwa zaka zambiri, osati panthawi yogula yokha.
• • Makina a laser olondola (femtosecond/picosecond) ndi nsanja zowunikira za optical/AOI, komwe kutentha pang'ono ngati ma microns ochepa kumatha kusintha mawonekedwe.
• • Ma plates apamwamba ndi ma granite squares/straightedges, omwe ndi muyezo wofunikira womwe zida zanu zina zimayesedwa motsutsana nawo — ngati reference yokha ikuyenda, chilichonse chomwe chimayesedwa motsutsana nawo chimayendanso.
• • Mapulatifomu a injini zolunjika, njira zoyendetsera galimoto ndi zoyezera mpira, komwe kusalala ndi kugwedezeka kwa kugwedezeka zimakhudza mwachindunji kulondola kwa kuyenda.

Malo osungira makina si malo odulira zinthu. Mwala womwe uli pansi pa zida zanu zolondola umagwira ntchito yokonza ndi kuwerengera zinthu tsiku lililonse.

Chenjezo: Si “Granite” Yonse Yofanana

Vuto limodzi lomwe ogula mumakampani awa amakumana nalo ndi ogulitsa omwe amagulitsa mwala wotsika - nthawi zina ngakhale wa marble kapena granite wotsika - ngati "granite wolondola" wapamwamba, chifukwa chakuti kusiyana kwa mawonekedwe sikuonekera popanda kuyesa kwa labu. Mtundu uwu wa kusintha ndi vuto lenileni mumakampani, ndipo ndi chinthu chomwe timachitsutsa mwamphamvu: maziko omwe amawoneka ngati gawo koma osagwira ntchito pa kuchulukana, kuuma, kapena kukhazikika kwa kutentha pamapeto pake adzawonekera ngati miyeso yosasinthasintha kapena kuwonongeka msanga, nthawi zambiri atagulitsidwa.

Pofufuza wogulitsa granite, ndi bwino kufunsa mwachindunji za:

• • Kuchuluka kwenikweni komwe kumayesedwa (osati "granite" yokha ngati chizindikiro)
• • Zikalata zoyeserera zolondola za kusalala ndi kumalizidwa kwa pamwamba
• • Kutsatira miyezo yovomerezeka (monga, DIN 876/875, ASME, JIS, GB, BS 817)

Muyezo wa ZHHIMG®

Ku ZHHIMG®, timagwiritsa ntchito granite wakuda wokhala ndi kuchuluka kwa ≈3,100 kg/m³ — wokwera kuposa magwero ambiri a granite aku Europe ndi America omwe amagwiritsidwa ntchito kwambiri, ndipo ndi woposa kwambiri kuposa momwe marble angapereke. Maziko athu a granite ndi zida zoyezera granite (ma plates apamwamba, ma square, straightedges, V-blocks, parallels) amapangidwa ndikulinganizidwa motsatira miyezo yapadziko lonse lapansi, ndipo ma plates athu apamwamba amakhala osalala mpaka kufika pamlingo wa nanometer — mulingo wolondola womwe makasitomala a semiconductor, metrology, ndi calibration amafunikira.

Tili ndi ziphaso za ISO 9001, ISO 45001, ISO 14001, ndi CE, ndipo chida chilichonse choyezera chomwe timagwiritsa ntchito poyang'anira khalidwe chimapezeka m'mabungwe a dziko lonse a metrology. Ponena za mwala womwe uli pansi pa zida zanu zolondola, tikukhulupirira kuti palibe malo a njira zazifupi — chifukwa m'mafakitale olondola kwambiri, maziko ndiye maziko a chilichonse chomwe chimayesedwa.
