Chifukwa Chake Zigawo za Makina a Precision Granite Zimakutidwa ndi Mafuta Musanatumize

Granite yolondola yakhala ikudziwika kwa nthawi yayitali ngati imodzi mwa zipangizo zodalirika kwambiri pakupanga makina olondola kwambiri komanso olondola kwambiri. Poyerekeza ndi chitsulo chosungunuka kapena chitsulo, granite yapamwamba imapereka kukhazikika kwapadera komanso kulondola kwa nthawi yayitali, zomwe zimapangitsa kuti ikhale yoyenera kwambiri pamalo ofunikira, maziko a makina, zothandizira zowongolera za mzere, ndi zigawo zofunika kwambiri zomwe zimagwiritsidwa ntchito mumakina oyezera ogwirizana, ma interferometer a laser, zida zoyezera za CNC, ndi machitidwe owunikira a semiconductor.

Funso limodzi lomwe ogwiritsa ntchito nthawi zambiri amafunsa ndi lakuti chifukwa chiyani zigawo za granite zolondola zimapakidwa mafuta ochepa asanatumizidwe, komanso chifukwa chake mafuta amalimbikitsidwa pamene zipangizozo sizigwiritsidwa ntchito kwa nthawi yayitali. Popeza granite sichita dzimbiri, mafutawo si oletsa dzimbiri. M'malo mwake, filimu yotetezayo imagwira ntchito yosiyana komanso yothandiza kwambiri: kuteteza kulondola kwa malo ogwirira ntchito.

Zigawo za granite zimapangidwa molimba kwambiri, ndipo pamwamba pake payenera kukhalabe ndi fumbi, tinthu tomwe timayabwa, ndi zinthu zina zodetsa. Ngakhale zinyalala zazing'ono zingakhudze kulondola kwa muyeso, ndipo kupukuta tinthu totere mouma kuchokera pamwamba kungayambitse kukanda pang'ono. Ngakhale granite imalimbana kwambiri ndi kusintha kwa zinthu ndipo sipanga ma burrs ngati chitsulo, kukanda kozama pamwamba kolondola kungakhudze magwiridwe antchito ndipo kungafunike kubwerezabwereza kapena kukonzedwa.

Pogwiritsa ntchito filimu yopepuka yamafuta—yomwe nthawi zambiri imakhala mafuta osinthira kapena mafuta osakaniza a makina ndi dizilo a 1:1—pamwamba pake pamakhala kosavuta kuyeretsa. Fumbi ndi tinthu tating'onoting'ono timamatira ku mafuta m'malo mwa mwala womwewo, ndipo tingachotsedwe pongopukuta filimuyo. Izi zimachepetsa chiopsezo chokoka tinthu tomwe timagunda pamwamba pa ntchito ndikusunga umphumphu wa nthawi yayitali wa malo ofunikira. Pazida zomwe zimasungidwa kwa nthawi yayitali, filimu yamafuta ndi yofunika kwambiri chifukwa kuchuluka kwa fumbi kumawonjezeka pakapita nthawi. Popanda mafuta, kuyeretsa kouma kungasiye zizindikiro kapena mikwingwirima yooneka yomwe imalepheretsa kulondola kwa muyeso.

Pakupanga, zigawo za granite zolondola nthawi zambiri zimafuna makina owonjezera kuti zigwirizane ndi makina ena. Kutengera ndi zojambula za makasitomala, kapangidwe ka granite kangakhale ndi zoyikapo ulusi, malo oyikapo T, mabowo ozungulira, kapena mabowo odutsa. Choyikapo chilichonse chimalumikizidwa pamalo pake mutachikonza mosamala graniteyo ku miyeso yodziwika, ndipo kulekerera kwa malo kuyenera kulamulidwa mwamphamvu kuti zitsimikizire kuti zikugwirizana bwino ndi zigawo zolumikizirana. Njira yokhwima yopangira - kuphimba kubowola, kulumikiza ma bushings achitsulo, ndi kumaliza komaliza pamwamba - kumaonetsetsa kuti zofunikira zonse za geometric zakwaniritsidwa ndipo gawolo limasunga kulondola kwake mutakhazikitsa.

Granite yapamwamba kwambiri imapereka maubwino angapo ofunikira pakugwiritsa ntchito uinjiniya wolondola. Ndi yokhazikika mwachilengedwe, yokhala ndi zovuta zamkati zomwe zimachokera pakukalamba kwa nthawi yayitali. Imalimbana ndi dzimbiri, chinyezi, ndi mankhwala ambiri. Kuchuluka kwake kochepa kwa kutentha kumachepetsa kusintha kolondola chifukwa cha kusinthasintha kwa kutentha. Ndipo mosiyana ndi pamwamba pa chitsulo, kugwedezeka pang'ono pa granite kumabweretsa mabowo ang'onoang'ono m'malo mwa ma burrs okwera, kotero malo ofunikira sasokonekera.

Pazifukwa izi, granite ikupitilizabe kugwira ntchito yofunika kwambiri pa metrology yamakono, zida za semiconductor, komanso kupanga zinthu zolondola kwambiri. Kusamalira bwino - monga kugwiritsa ntchito filimu yamafuta musanatumize kapena kusungirako kwa nthawi yayitali - kumathandiza kuonetsetsa kuti gawo lililonse la granite lolondola limasunga magwiridwe ake kuyambira fakitale mpaka wogwiritsa ntchito, kuthandizira muyeso wodalirika komanso kupanga molondola kwambiri m'mafakitale osiyanasiyana.
