Pa mpikisano wopita ku malire a nanometer, zofuna zomwe zimayikidwa pa kulondola kwa kupanga zikuwonjezeka kwambiri. Mainjiniya amapanga makina osinthika okhala ndi ma sub-micron feedback loops ndipo amagwiritsa ntchito zipangizo zachilendo, komabe muyeso womaliza wa ubwino nthawi zambiri umadalira maziko osavuta komanso okhazikika omwe alipo: granite yolondola.mbale yoyezera pamwamba pa granite, yomwe nthawi zambiri imagwira ntchito ngati Granite Metrology Table, si chida chokha; ndi mawonekedwe enieni a zero plane, malo ofunikira omwe amatsimikizira gawo lina lililonse mu dongosolo lolondola kwambiri.
Yankho lathunthu—lomwe limaphatikizapo mbale yakuda yolondola ya granite pamwamba pake, mbale yapadera ya granite pamwamba pake yokhala ndi chithandizo, ndi tebulo lonse loyezera granite yokhala ndi choyimilira—likuyimira pamwamba pa kukhazikika kwa miyeso yopanda kanthu. Zida izi ndi nangula yomwe chisokonezo cha malo opangira zinthu chimasefedwa, kuonetsetsa kuti zotsatira za muyeso ndizolondola komanso zodalirika.
Fiziki Yosasinthika ya Black Precision Granite Surface Plate
Chidaliro chosasinthika chomwe chimayikidwa mu granite pamwamba pa zipangizo zina (monga chitsulo kapena konkireti ya polima) chimachokera ku zinthu ziwiri zofunika kwambiri: kukhazikika kwa kutentha kwapadera ndi kugwedezeka kwapamwamba.
Kukhazikika kwa Kutentha: Ubwino Wotsika wa CTE
Mu malo aliwonse olamulidwa ndi nyengo, kusinthasintha pang'ono kwa kutentha n'kosapeweka. Pa zida zachitsulo, izi zimayambitsa kusakhazikika kwa magawo chifukwa cha kuchuluka kwa Coefficient of Thermal Expansion (CTE). Chitsulo chachitsulo chimatha kusuntha ma micrometer angapo pa kutentha pang'ono, zomwe zimawononga nthawi yomweyo kulondola.
Kulondola kwakudambale za granite pamwamba, makamaka zomwe zimachokera ku malo okhala ndi kuchuluka kwakukulu kwa geological (monga zinthu za ZHHIMG zomwe zimafika 3100 kg/m³), zimakhala ndi CTE yotsika kwambiri. Kapangidwe ka zinthuzi kamathandizira kuti kusintha kwa mawonekedwe a malo oyezera kuchepe, zomwe zimapangitsa kuti zikhale zoona mosasamala kanthu za kusintha kwa kutentha kwa nthawi zonse. Kuphatikiza apo, kutentha kwakukulu kwa granite yolemera kwambiri kumathandizira kuti isagwere kutentha mwachangu, kuonetsetsa kuti kutentha komwe kumachitika chifukwa cha kukhudzana kapena zida zoyezera sikusokoneza mawonekedwe a pamwamba.
Kuchepetsa Mphamvu: Kuletsa Chilengedwe
Mu labotale ya metrology, kulondola kwa makina kuyenera kuchotsedwa ku kugwedezeka kwa pansi. Kapangidwe ka kristalo ka Granite kamapatsa mphamvu yayikulu yochepetsera kutentha mkati, zomwe zikutanthauza kuti imayamwa mphamvu yamakina mwachangu ndikuisintha kukhala kutentha kochepa. Zida Zoyezera za Granite zapamwamba zikayikidwa pa mbale, granite imaletsa bwino kugwedezeka, kuletsa phokoso la chilengedwe kuti lisawononge miyeso yofewa yochitidwa ndi ma CMM, ma profiler optical, kapena ma laser interferometers. Malo odekha awa a kinetic sangakambiranedwe poyang'ana nanoscale.
Kuchokera ku Slab kupita ku System: Tebulo Loyezera Granite Lokhala ndi Choyimilira
Ngakhale kuti granite slab yokha imapereka kukhazikika, tebulo loyezera granite lokhala ndi choyimilira limasintha malo osagwira ntchito kukhala siteshoni yoyezera zinthu yogwira ntchito bwino komanso yogwirizana. Kapangidwe ka makina othandizira ndi kofunikira kwambiri monga momwe mbaleyo imagwirira ntchito.
Kuphatikiza kwa mbale ya granite pamwamba ndi chithandizo kumapangidwa kuti kusunge umphumphu wotsimikizika wa geometry wa mbaleyo. Kapangidwe ka chithandizo nthawi zambiri kamapangidwa kuti kagwirizane bwino ndi mfundo za Airy kapena mfundo za Bessel zomwe zimawerengedwa pa mbaleyo, zomwe ndi mfundo zabwino kwambiri zothandizira zomwe zimagawa kupsinjika mofanana ndikuchepetsa kupotoka pamwamba ponseponse. Pa mbale zazikulu kwambiri kapena zolemera, njira zothandizira zambiri zimagwiritsidwa ntchito, nthawi zambiri zimakhala ndi mapazi osinthika kapena ma vibration isolation pads ophatikizika.
Tebulo loyezera la granite lapamwamba kwambiri lokhala ndi choyimilira limaonetsetsa kuti kusalala kwa mbaleyo kusungidwa bwino. Kusagwirizana kulikonse pakulimba kwa choyimilira kapena kulondola kwa kulinganiza nthawi yomweyo kumabweretsa kusokonekera, zomwe zimapangitsa kuti mbale yonseyo ikhale yopanda ntchito pa ntchito yolondola kwambiri. Chifukwa chake, dongosolo lonse la tebulo nthawi zambiri limaonedwa ngati gawo limodzi, lokonzedwa bwino la Granite Metrology Table, lolinganizidwa bwino komanso lovomerezeka pamalo omwe kasitomala ali.
Chilengedwe cha Zida Zoyezera Granite
Kugwiritsa ntchito kwa mbale yoyezera ya granite pamwamba kumachitika kudzera mu Zida Zoyezera za Granite. Zowonjezera izi—mabwalo a granite, m'mbali molunjika, ma V-block, ndi kufanana—ziyenera kupangidwa ndi zinthu zomwezo za granite kuti zitsimikizire kuti zinthuzo zikugwirizana panthawi yonse yoyezera. Izi ndizofunikira kwambiri kuti kutentha kukhale kofanana komanso kuti zinthu zonse zomwe zikugwiritsidwa ntchito poyesa zisamayende bwino.
Poyang'ana kukula kwa chogwirira chovuta, mwachitsanzo, kufanana kwa sikweya ya granite poyerekeza ndi mbale, kulunjika kwa wolamulira wa granite, ndi kusalala kwa mbale yoyezera granite pamwamba ziyenera kukhala zogwirizana bwino komanso zotsimikiziridwa. Kukhazikika kwa zida izi - zonse pogwiritsa ntchito mphamvu zapamwamba za granite - kumatsimikizira kuti zolakwika za geometric zomwe zapezeka ndi zolakwika mu workpiece, osati njira yoyezera.
Ulamuliro wa Magiredi ndi Ukadaulo
Kupanga mbale ya granite yakuda yapamwamba kwambiri padziko lonse lapansi kumaposa kupanga kokha; kumafuna kuphatikiza ukadaulo wapamwamba ndi luso la anthu losayerekezeka.

Kutha Kwambiri: Ogulitsa otsogola ayenera kukhala ndi zomangamanga kuti azitha kugwiritsa ntchito ma metrology plates akuluakulu padziko lonse lapansi, omwe amafunikira zida zapadera za CNC zomwe zimatha kugwira zinthu zolemera matani 100 ndi kutalika kwa 20m.

Kulondola Kotsimikizika: Kusalala komaliza kumachitika kudzera mu njira yovuta yolumikizirana ndi manja, yochitidwa ndi akatswiri aluso omwe ali ndi zaka zambiri akugwira ntchito. Kutha kwawo kukwaniritsa kusalala kwa Giredi 00 kapena Giredi A, komwe kumayesedwa m'zigawo za micron kapena nanometers, kumatsimikiziridwa pogwiritsa ntchito zida zapamwamba monga laser interferometers, zonse zomwe zimatsatiridwa ndi miyezo yapadziko lonse lapansi (NIST, PTB, NPL).

Kutsatira Malamulo Padziko Lonse: Dongosolo la khalidwe liyenera kutsimikiziridwa kuti likutsatira miyezo yosiyanasiyana yapadziko lonse (ISO 9001, 14001, 45001) komanso likhoza kutsimikizira kuti ma plates ali ndi miyezo yosiyanasiyana, kuphatikizapo DIN, ASME, JIS, ndi GB, kuonetsetsa kuti Granite Metrology Table ikukwaniritsa zofunikira kwambiri padziko lonse lapansi.
Kutalika ndi ulamuliro wa Zida Zoyezera za Granite izi zikusonyeza mfundo yofunika kwambiri: mu nthawi ya automation yosinthasintha, chowonadi cha geometry chiyenera kukhala chopanda kanthu, chokhazikika, komanso chosavuta kutsatira. Mbale ya granite pamwamba yokhala ndi chithandizo, yomwe imagwira ntchito ngati ndege yomaliza ya zero-reference, imakhalabe maziko osagwedezeka a kulumpha kulikonse kwaukadaulo muukadaulo wolondola kwambiri.
