Kuwunika kwaubwino ndi zoyipa za XYT precision active vibration isolation movement platform granite base.

Choyamba, ubwino wa granite m'munsi
1. Kukhazikika kwakukulu ndi kukhazikika
Granite ali ndi kachulukidwe kwambiri (2.6-3.1g / cm³), ndipo modulus ya Young (elastic modulus) imatha kufika ku 50-100 GPa, yokwera kwambiri kuposa chitsulo wamba (pafupifupi 200 GPa), koma chifukwa cha mawonekedwe ake a kristalo wa isotropic, pafupifupi ilibe kupindika kwa pulasitiki pakugwiritsa ntchito nthawi yayitali. Poyerekeza ndi zida zachitsulo, granite matenthedwe kukulitsa koyenera ndi otsika kwambiri (pafupifupi 5 × 10⁻⁶/℃), mu kutentha kusinthasintha chilengedwe akhoza kukhalabe bwino dimensional bata, kupeŵa chifukwa matenthedwe matenthedwe kuzizira kumakhudza kulondola kwa zipangizo.

2. Wabwino kugwedera kuchepetsa ntchito
Mapangidwe a kristalo amkati a granite ali ndi kunyowa kwakukulu kwamkati, komwe kumatha kuyamwa bwino kwambiri kugwedezeka ndikuchepetsa kumveka kwa resonance. Poyerekeza ndi maziko achitsulo, granite imakhala ndi mphamvu yochepetsera kugwedezeka kwapakati pa 20Hz-1kHz, kumapereka malo oyambira "oyera" a dongosolo lodzipatula la vibration ndikuchepetsa kulemetsa kwa kuwongolera kotsatira.

3. Kukana kwa dzimbiri, kusakhala ndi maginito, kugwiritsidwa ntchito kwakukulu
Kukhazikika kwamankhwala a granite, asidi ndi kukana kwa dzimbiri za alkali, sikukhala dzimbiri kapena makutidwe ndi okosijeni, oyenera chipinda choyera, chinyezi chachikulu kapena malo owononga. Kuphatikiza apo, granite ndi chinthu chopanda maginito, sichingasokoneze zida zolondola (monga ma electron microscopy, zida zoyezera maginito, ndi zina zotero), zoyenera pazithunzi zogwiritsa ntchito ma elekitiroma.

4. Moyo wautali wautumiki, mtengo wotsika wokonza
Kuuma kwa granite ndikwapamwamba (Mohs kuuma 6-7), kuvala kukana, kugwiritsa ntchito nthawi yayitali sikophweka kuvala kapena kusinthika, moyo wautumiki ukhoza kufika zaka zoposa 20. Poyerekeza ndi zida zachitsulo, sizifuna chithandizo chanthawi zonse odana ndi dzimbiri kapena mafuta, ndipo ndalama zolipirira ndizotsika kwambiri.

5.Kukhazikika kwapamwamba komanso kutha kwapamwamba
Kupyolera mwatsatanetsatane akupera ndi kupukuta, flatness wa m'munsi mwa granite akhoza kufika 0.005mm/m², ndi pamwamba roughness Ra≤0.2μm, kuonetsetsa kukwanira bwino ndi zipangizo mwatsatanetsatane (monga kuwala nsanja, laser interferometer) ndi kuchepetsa zolakwa msonkhano.

Chachiwiri, zolakwika za granite maziko
1. Kulemera kwakukulu, kovuta kunyamula ndi kukhazikitsa
Granite imakhala ndi kachulukidwe kakang'ono ndipo imakhala yolemera kuposa aluminiyumu kapena chitsulo pamlingo womwewo, kupanga kugwira ndi kukhazikitsa nsanja zazikulu kumafunikira zida zapadera (monga ma forklift kapena zida zonyamulira), kuchulukitsa ndalama zotumizira.

2. High brittleness, ofooka mphamvu kukana
Ngakhale granite imakhala yolimba kwambiri, imakhala yosasunthika ndipo imatha kusweka kapena kugwa ikakhudzidwa kwambiri (monga kugwa kapena kugunda). Chifukwa chake, chisamaliro chowonjezereka chiyenera kuchitidwa panthawi yoyendetsa ndi kuikapo kuti mupewe kugwedezeka kwakukulu kapena kukhudzidwa.

3. The processing ndizovuta ndipo mtengo makonda ndi mkulu
Kukonzekera kwa granite kumafuna zida zapadera zamakina (monga makina ojambulira miyala ya CNC) ndi zida za diamondi, ndipo kuthamanga kwachangu kumachedwa, zomwe zimapangitsa kuti pakhale kukwera mtengo kwa mapangidwe ovuta (monga mabowo opangidwa ndi ulusi, ma grooves ooneka ngati apadera) ndi ulendo wautali wobereka.

4. Kusintha kwadzidzidzi kutentha kungayambitse ma microcracks
Ngakhale kuti granite imakhala ndi kukhazikika kwabwino kwa kutentha, ngati ikukumana ndi kusintha kwa kutentha kwakukulu (monga kusuntha mofulumira kuchokera kumalo otsika kutentha kupita kumalo otentha kwambiri), ming'alu yaing'ono yopanikizika imatha kuchitika mkati, ndipo kudzikundikira kwa nthawi yaitali kungakhudze mphamvu ya kapangidwe kake. Choncho, iyenera kugwiritsidwa ntchito mosamala m'madera omwe ali ndi kusiyana kwakukulu kwa kutentha.

5. Palibe kuwotcherera kapena processing yachiwiri
Chitsulo chachitsulo chikhoza kusinthidwa ndi kuwotcherera kapena kupanga makina, koma granite ikapangidwa, zimakhala zosatheka kupanga zosinthika (monga kubowola, kudula), kotero kuti mapangidwe apangidwe ayenera kukonzedwa bwino kuti apewe kusinthidwa pambuyo pake.
