Monga chida chachikulu cha metrological popanga zinthu molondola, Granite CMM Platform (yomwe imadziwikanso kuti tebulo la makina oyezera marble coordinate, tebulo loyezera granite molondola) imadziwika kwambiri chifukwa cha kukhazikika kwake komanso kulondola kwake kwapamwamba. Dziwani: Nthawi zina imagawidwa molakwika ndi nsanja za CMM zachitsulo zotayidwa pamsika, koma kapangidwe ka mchere wachilengedwe ka granite kamapatsa ubwino wosasinthika m'mikhalidwe yoyezera molondola kwambiri - kusiyana kwakukulu kwa akatswiri omwe akufunafuna miyezo yodalirika ya metrological.
1. Tanthauzo Lalikulu & Mapulogalamu Oyambirira
Pulatifomu ya granite CMM ndi chida choyezera molondola chomwe chimapangidwa kuchokera ku granite wachilengedwe wapamwamba kwambiri, chopangidwa kudzera mu njira zopangira machining a CNC ndi kumaliza ndi manja. Ntchito zake zazikulu ndi monga:
- Kugwira ntchito ngati maziko ogwirira ntchito za makina oyezera (CMM), zomwe zimathandiza kuwunika molondola magawo a zida zamakanika.
- Kuthandizira kuyesa molondola kwa zida zamakina, kutsimikizira kulondola kwa geometric (monga kusalala, kufanana) kwa matebulo ogwirira ntchito a zida zamakina.
- Kuchita kulondola kwa miyeso ndi kuwunika kupotoka kwa mawonekedwe a ziwalo zolondola kwambiri (monga zigawo za ndege, zigawo zolondola zamagalimoto).
- Ili ndi zizindikiro zitatu zodziwika bwino pamalo ake ogwirira ntchito, zomwe zimathandiza kuti ma CMM probe azitha kuyeza bwino komanso kuti azitha kuyeza bwino.
2. Kapangidwe ka Mchere ndi Ubwino wa Magwiridwe Achilengedwe
2.1 Kapangidwe Kofunika ka Mchere
Mapulatifomu apamwamba a granite amapangidwa makamaka ndi:
- Pyroxene (35-45%): Imawonjezera kuchulukana kwa kapangidwe kake komanso kukana kuwonongeka.
- Plagioclase feldspar (25-35%): Imaonetsetsa kuti kapangidwe kake ndi kofanana komanso kutentha kochepa kumawonjezeka.
- Michere yocheperako (olivine, biotite, magnetite): Imathandizira ku kuwala kwakuda kwa chinthucho komanso kukana maginito.
Pambuyo pa zaka mazana ambiri zakukalamba mwachilengedwe, kupsinjika kwamkati kwa granite kumatulutsidwa kwathunthu, zomwe zimapangitsa kuti pakhale kapangidwe kokhazikika ka kristalo komwe kamachotsa kusintha kwa zinthu pambuyo pokonza - ubwino wapadera kuposa zipangizo zopangidwa ndi anthu.
2.2 Ubwino wa Zaukadaulo
Poyerekeza ndi nsanja zachitsulo chopangidwa ndi chitsulo kapena zinthu zophatikizika, nsanja za granite CMM zimapereka magwiridwe antchito osayerekezeka:
- Kukhazikika Kwapadera: Kusapsinjika kwamkati chifukwa cha ukalamba wachilengedwe sikupangitsa kuti pasakhale kusintha kwa mawonekedwe pakatha nthawi yayitali kapena katundu wolemera (mpaka 500kg/m² ya mitundu yokhazikika).
- Kulimba Kwambiri ndi Kukana Kuvala: Kulimba kwa Mohs kwa 6-7 (kupitirira 4-5 ya chitsulo chopangidwa ndi chitsulo), kuonetsetsa kuti pamwamba pake pasawonongeke ngakhale patatha nthawi yoyezera 10,000+.
- Kukana Kudzikundikira ndi Maginito: Sizimakhudzidwa ndi ma asidi, alkali, ndi zosungunulira zamafakitale; mphamvu zopanda maginito zimapewa kusokoneza zida zoyezera maginito molondola.
- Kuwonjezeka kwa Kutentha Kochepa: Kuchuluka kwa kukula kwa mzere wa 5.5×10⁻⁶/℃ (1/3 ya chitsulo chosungunuka), kuchepetsa kusinthasintha kwa mawonekedwe komwe kumachitika chifukwa cha kusinthasintha kwa kutentha kwa mlengalenga.
- Kusamalira Kochepa: Malo osalala, okhuthala (Ra ≤ 0.4μm) safuna kutetezedwa ku dzimbiri kapena mafuta odzola nthawi zonse; kupukuta kosavuta ndi nsalu yopanda ulusi kumasunga ukhondo.
3. Miyezo Yolondola & Zofotokozera Zololera
Kulekerera kwa ma granite CMM platforms kumagwirizana kwambiri ndi muyezo wa GB/T 4987-2019 (wofanana ndi ISO 8512-1) ndipo umagawidwa m'magulu anayi olondola. Fomula yolekerera kufooka ndi iyi: (D = kutalika kwa malo ogwirira ntchito, mm; kutentha koyezera: 21±2℃):
- Kalasi 000 (Kulondola Kwambiri): Kulekerera = 1×(1 + D/1000) μm (koyenera ma CMM olondola kwambiri m'malo ochitira kafukufuku).
- Kalasi 00 (Kulondola Kwambiri): Kulekerera = 2×(1 + D/1000) μm (yabwino kwambiri kwa ma CMM apamwamba kwambiri m'mafakitale opanga magalimoto/mlengalenga).
- Kalasi 0 (Kulondola): Kulekerera = 4×(1 + D/1000) μm (yogwiritsidwa ntchito poyesa zida zamakina ndi kuyang'ana mbali).
- Kalasi 1 (Yokhazikika): Kulekerera = 8×(1 + D/1000) μm (yogwiritsidwa ntchito poyang'anira khalidwe la makina okhwima).
Mapulatifomu onse a granite OSAFANANA amatsimikiziridwa ndi anthu ena, ndipo lipoti lolondola lolondola limaperekedwa pa chipangizo chilichonse— kuonetsetsa kuti zikugwirizana ndi zofunikira zapadziko lonse lapansi.
4. Zofunikira ndi Zolepheretsa Pamalo Ogwirira Ntchito
4.1 Zikhalidwe Zabwino pa Malo Ogwirira Ntchito
Kuti zitsimikizire kulondola kwa muyeso, malo ogwirira ntchito a nsanja za granite CMM ayenera kukhala opanda zolakwika zomwe zimakhudza magwiridwe antchito, kuphatikizapo:
- Mabowo a mchenga, mabowo ophwanyika, ming'alu, kapena zinthu zina (zomwe zimayambitsa kufalikira kwa mphamvu kosagwirizana).
- Kukanda, kusweka, kapena dzimbiri (zomwe zimasokoneza mfundo zoyezera).
- Kupindika kapena kapangidwe kosagwirizana (zomwe zimapangitsa kuti kuvala kusakhale kofanana).
Malo osagwira ntchito (monga m'mbali mwa denga) amalola akatswiri kukonza zolakwika zazing'ono kapena chamfer, bola ngati sizikukhudza kapangidwe kake.
4.2 Zolepheretsa Zaukadaulo ndi Kuchepetsa Mavuto
Ngakhale kuti nsanja za granite zimapambana bwino kwambiri, zili ndi zofooka zomwe akatswiri ayenera kuzizindikira:
- Kukhudzidwa ndi Kukhudzidwa: Sizingapirire kugunda kwakukulu (monga kugwetsa zitsulo); kugundako kungayambitse ma micro-pit (ngakhale osati ma burrs, zomwe zimapewa kusokoneza kulondola kwa muyeso).
- Kuzindikira Chinyezi: Kuchuluka kwa kuyamwa kwa madzi ndi ~1%; kuwonetsedwa nthawi yayitali ku chinyezi chambiri (>60%) kungayambitse kusintha pang'ono kwa mawonekedwe. Kuchepetsa: Ikani chophimba chosalowa madzi chapadera chopangidwa ndi silicone (choperekedwa kwaulere ndi maoda OSAFANANA).
5. N’chifukwa Chiyani Muyenera Kusankha Mapulatifomu a CMM OSATI ALI POSAFANANA NDI A Granite?
- Kupeza Zinthu: Timagwiritsa ntchito granite ya “Jinan Black” yokha (yomwe ili ndi zinthu zosafunika kwambiri kuposa 0.1%), kuonetsetsa kuti kapangidwe kake ndi kofanana komanso kuti zinthu zikuyenda bwino.
- Kukonza Machining Mwanzeru: Njira zophatikizana za CNC zopera (kulekerera ± 0.5μm) ndi kupukuta ndi manja (Ra ≤ 0.2μm) zimaposa miyezo yamakampani.
- Kusintha: Timapereka kukula kosakhazikika (kuyambira 300×300mm mpaka 3000×2000mm) ndi mapangidwe apadera (monga mipata ya T-slot, mabowo opindika) kuti agwirizane ndi mtundu wanu wa CMM.
- Thandizo Pambuyo pa Kugulitsa: Chitsimikizo cha zaka ziwiri, kukonzanso kolondola kwapachaka kwaulere, komanso kukonza padziko lonse lapansi (kukhudza Europe, North America, ndi Southeast Asia).
