Mu labotale yolondola yopangira ma chips, pali "ngwazi yakumbuyo" yomwe imawoneka yosadabwitsa - maziko a makina a granite. Musanyoze mwala uwu. Ndi chinsinsi chotsimikizira kulondola kwa mayeso osawononga a ma wafers! Lero, tiyeni tiwone momwe zimasungira zida zodziwira nthawi zonse "zolunjika komanso zoyimirira".
1. Wobadwa ndi "jini lokhazikika"
Granite si mwala wamba. Kapangidwe kake kamkati kali ngati "mineral jigsaw puzzle" yolumikizidwa bwino. Quartz, feldspar ndi makhiristo ena amakonzedwa bwino, okhala ndi kuchuluka kwakukulu komanso pafupifupi opanda mabowo. Izi zili ngati kumanga nyumba ndi konkriti yolimbikitsidwa, yomwe ndi yolimba komanso yokhazikika. Zipangizo zowunikira "zikakhala" pamenepo, ngakhale zitalemera matani angapo, kusintha kwa maziko a granite kumakhala kochepa, gawo limodzi mwa magawo khumi okha a chitsulo!
Chodabwitsa kwambiri n'chakuti sichiopa kusintha kwa kutentha. Zipangizo zachitsulo wamba nthawi zambiri "zimakula ndikulemera" zikatenthedwa ndipo "zimachepa ndikuchepa" zikazizira. Komabe, granite imawoneka kuti ili ndi "matsenga otentha nthawi zonse". Kutentha kukasinthasintha ndi 1℃, kukula ndi kupindika kwake kumakhala gawo limodzi mwa magawo chikwi a tsitsi la munthu. Tiyenera kudziwa kuti ngakhale patakhala kusintha pang'ono kwa kutentha kwa labotale yoyesera, maziko a granite amatha kuthandizira zidazo mwamphamvu ndikuletsa kuti "zisapatuke".
Chachiwiri, njira yogwiritsira ntchito "tsatanetsatane wa mdierekezi"
Kuti maziko a granite akhale olondola kwambiri, mainjiniya adagwiritsa ntchito "ukadaulo wakuda" pokonza. Tangoganizani kupukuta miyala ndi "super sandpaper" yopangidwa ndi diamondi - umu ndi momwe makina opukutira a five-axis amagwirira ntchito. Adzapukutira pamwamba pa granite kuti pakhale pabwino kuposa galasi m'magawo atatu:
Kupera mopanda mphamvu: Choyamba, chotsani zipsera pamwamba pa mwalawo ndikulamulira kusalala kwake kufika pa gawo limodzi mwa magawo makumi awiri a tsitsi la munthu.
Kupera pang'ono: Kukonzanso kwina, ndi kusalala kwa tsitsi la munthu komwe kumawonjezeka kufika pa gawo limodzi mwa magawo asanu.
Kupera pang'ono: Pomaliza, imapukutidwa ndi ufa wopera wopyapyala kwambiri, zomwe zimapangitsa kuti tsitsi la munthu likhale losalala ngati chikwi chimodzi! Pakadali pano, pamwamba pa maziko a granite pali ngati "gawo lopingasa" lopangidwira zida zowunikira.
Ma mount ena apamwamba alinso ndi "ubongo wanzeru" - mulingo wolondola kwambiri womangidwa mkati mwake uli ngati "mlonda wamng'ono" amene amagwira ntchito maola 24 patsiku. Akangozindikira kuti chipangizocho chapendekeka ndi madigiri 0.01 (Ngodya yaying'ono kuposa ya nsonga ya cholembera), chipangizo cha hydraulic chidzayamba kugwira ntchito nthawi yomweyo ndi "kuwongola" chipangizocho mkati mwa masekondi 30.
Chachitatu, kapangidwe kabwino kamawonjezera kukhazikika
Mainjiniya nawonso adaganizira kwambiri kapangidwe ka maziko a makinawo. Pansi pake papangidwa ngati chisa cha hexagonal, monga momwe njuchi imagwirira ntchito, zomwe sizimangochepetsa kulemera kwake komanso zimagawa mphamvu mofanana. Pamene chofufuzira chozindikira chikuyenda pa wafer, kusintha kulikonse kwa maziko kumakhala kofanana, kuonetsetsa kuti malo ozungulira amakhalabe olimba nthawi zonse.
Chodabwitsa kwambiri n'chakuti "chosawoneka bwino choyamwa ma shock" - choyamwa ma shock cha piezoelectric ceramic - chimayikidwa pakati pa maziko ndi nthaka. Chimatha kujambula ma volts osiyanasiyana kuyambira 1 mpaka 1000Hz ngati radar ndipo nthawi yomweyo chimatulutsa mafunde obwerera m'mbuyo kuti "chithetse" kusokoneza. Mwachitsanzo, ma volts omwe amapangidwa ndi makina oyandikana nawo kapena kugwedezeka kwa magalimoto omwe amadutsa panja onse "ndi opanda ntchito" patsogolo pake.
Deta imadzilankhulira yokha: Kodi zotsatira zake ndi zamphamvu bwanji?
Mu ntchito zenizeni, magwiridwe antchito a maziko a granite ndi odabwitsa kwambiri:
Kuyang'anira kwa maso: Kulondola kwa kuzindikira zolakwika pamwamba pa ma wafer kwawonjezeka kuchoka pa ma micron atatu kufika pa micron imodzi (micron imodzi = gawo limodzi mwa makumi asanu ndi limodzi la tsitsi la munthu).
Kuyesa kwa Ultrasound: Cholakwika pakuyesa makulidwe a wafer chachepetsedwa ndi magawo atatu mwa anayi.
Kugwiritsa ntchito kwa nthawi yayitali: Pambuyo pogwira ntchito mosalekeza kwa chaka chimodzi, kusintha kwa kusinthasintha kumakhala kochepa kwambiri, pomwe maziko wamba a makina akhala "owerama".
Kuchokera ku ubwino wa zinthu zachilengedwe mpaka kukonza bwino komanso kapangidwe katsopano, maziko a granite atsimikizira ndi "mphamvu" yake kuti ngati mukufuna kuzindikira tchipisi molondola, mwala uwu ndi wofunika kwambiri!
