Pali mitundu itatu ya makina opukusira a labotale: spindle yopingasa, spindle yoyimirira, ndi creep-feed. Kupindika, liwiro, ndi kupanikizika kwa kugaya zonse ndi zinthu zofunika kuziganizira posankha makina. Izi zingakuthandizeni kupeza makina opukutira abwino kwambiri.
Chopukusira pamwamba ndi chopindika choyimirira makina opukusira ufa wa ultrafineChopukusira chamtunduwu chimagwiritsidwa ntchito popukusira mwachangu zinthu zazikulu komanso zathyathyathya. Nthawi zambiri chimagwiritsidwa ntchito popanga mbale zazikulu ndi mapanelo.
Kupera pamwamba pa spindle yolunjika kumapatsa ntchitoyo kumaliza kosalala, kofanana, komanso kokhalitsa. Ntchitoyo imaphwanyidwa ndi tinthu tomwe timagundana pamwamba pa gudumu. Kupera pamwamba pa spindle yolunjika kumapanga mawonekedwe odulirana pamwamba. Kuzama kwa chitsanzo kumatsimikiziridwa ndi liwiro, kuchuluka kwa chakudya, zida zogwirira ntchito, ndi kusankha mawilo.
Spindle yomwe ndi yoyimirira yogwiritsa ntchito mawilo odziyimira payokha ndi njira ina yogwiritsira ntchito makina opukusira abwino kwambiri. Amathanso kupanga mipata ndi ma diagonal. Amathanso kupukusira zinthu zamaginito ndipo ndi oyenera kupukusira zinthu zambiri.
Mwachitsanzo, mndandanda wa Magerle umachita bwino kwambiri pogaya zinthu. Makinawa amathanso kukonza zinthu zolimba kwambiri. Ma bearing race, ma pini, ma solar panels, ndodo zolumikizira, ndi zovala ndi zitsanzo za momwe zimagwiritsidwira ntchito.
Makina awa amapezeka m'makulidwe osiyanasiyana. Pazinthu zopukutira magalimoto, zipangizo zamlengalenga, ndi chakudya, mtundu umodzi uli ndi ma spindle awiri osiyana.
Chitsanzochi cholinga chake ndi kukweza mphamvu yamagetsi pamene chikupitirizabe kukhala ndi khalidwe labwino kwambiri. Kudyetsa koyima kwa mutu kumayendetsedwa ndi mota ya AC servo. Chithandizo cha mizati itatu chimalola kuti spindle isinthidwe pang'ono poyerekeza ndi chuck.
Bedi la makinawa lapangidwa ndi chitsulo champhamvu kwambiri. Izi zimathandiza kuchepetsa kugwedezeka ndi kugwedezeka. Chosungira cha hydraulic ndi chinthu china. Flange ya mawilo a triangle segment ndi chowonjezera chachizolowezi.
Makina opukusira opindika bwino kwambiri okhala ndi spindle yolunjika alinso ndi mphamvu yopangira malo osalala kwambiri. Mitundu ina ya makina opukusira pamwamba imataya kusalala kumeneku pamene gudumu likutha, koma si makina opukusira opindika.
Chopindika choyimirira. Mawonekedwe ake amapangidwa ndi kapu kapena gudumu la silinda, kutengera wopanga makina opukutira bwino kwambiri. Kusalala kwa gudumu kumasungidwa chifukwa chopukutira chamtunduwu sichigwiritsa ntchito njira yomangira kuti chipangidwe.
Zogayira izi zimagwiritsidwa ntchito popanga mbale zazikulu ndi mapanelo kuwonjezera pa kugayira malo athyathyathya. Chifukwa cha kusinthasintha kwawo, ndi chisankho chabwino kwambiri cha ma stator, mphete zamkati, ndi mbale.
Kupera chakudya chophwanyika ndi njira yabwino yosalala ndi kupukuta malo ovuta ogwirira ntchito. Ikhozanso kuwonjezera kulondola kwa njira ndi kuberekana.
Njirayi imaphatikizapo kukonza gudumu lopukusira kuti ligwirizane ndi mawonekedwe a ntchitoyo. Njira yopangira kuvala imakhala yopambana kwambiri ikachitika mosalekeza. Izi zimapangitsa gudumu kukhala lolimba nthawi zonse.
Mukagwiritsa ntchito chakudya cha creep kugaya kwa ultrafine, makinawo ayenera kukhala okhoza kupirira kupsinjika kwakukulu ndi mphamvu. Kuphatikiza apo, makinawo ayenera kukhala ndi makina amphamvu oziziritsira. Chifukwa chake, makinawo ayenera kukhala ndi mphamvu yayikulu yozungulira. Izi ndizofunikira chifukwa kutentha kwambiri kumapangitsa kuti ntchitoyo ipse.
Ubwino wina wa creep feed grinding ndi kuthekera kochotsa zinthu zambiri munthawi yochepa. Izi zingakuthandizeni kusunga ndalama pokonzanso makina. Kuphatikiza apo, MRR (chiwerengero chochotsera zinthu) chapamwamba chingathandize kupanga bwino.
Ngakhale kuti njira yopukusira iyi ndi yopambana kwambiri pakukonza, si yoyenera kugwiritsidwa ntchito pa ntchito zonse. Izi zimachitika chifukwa cha kuwonongeka kwa gudumu mwachangu komanso kufunika kokonza gudumu.
Njira yatsopano yogwiritsira ntchito izi imadziwika kuti kupukuta kopitilira muyeso. Imachepetsa kuwonongeka kwa mawilo mwachangu komanso imathandiza kupewa kutembenuka.
Ubwino wina wa njirayi ndi kugwiritsa ntchito zipangizo zomangira bwino mu gudumu lopera. Izi zimathandiza kuti njere zikhalebe mu matrix yomangira kwa nthawi yayitali. Chifukwa cha kupita patsogolo kumeneku, MRR ya creep-feed grinding yafika pamlingo wopera.
Njirayi ilinso ndi kuzama kodulira. Chifukwa chake, kuuma kwa pamwamba pa chinthucho kumakhala kocheperako kuposa pogaya mwachizolowezi. Izi zimachepetsa kuchuluka kwa maola ogwirira ntchito komanso gawo lopanda kanthu lokonza.
Njirayi imapangitsanso kutentha kochepa. Komabe, ngati gudumu lopukusira silinaphimbidwe bwino, kutentha kwa chogwirira ntchito kungakwere. Kutentha kwambiri kungayambitse kupsa, kuwotcherera, kapena kusweka kwa gudumu.
Ndikofunikanso kusankha chogwirira choyenera. Izi zimachitika chifukwa cha kuphatikiza kwa tinthu tating'onoting'ono/tinthu tating'onoting'ono, momwe chimagwirira ntchito, komanso momwe chimagayidwira.
Siziyenera kudabwitsa kuti liwiro la makina opukusira abwino kwambiri Zimakhudza kwambiri kugayidwa kwa mchere. Izi zimatsimikiziridwa ndi kuchuluka kwa chinthucho komanso makhalidwe ake enieni. Komabe, zotsatira zabwino kwambiri zidzapezeka ngati mpheroyo ikugwiritsidwa ntchito pa liwiro labwino kwambiri.
Zotsatira za makhalidwe a zinthu zakuthupi pakupanga zinthu zazing'ono panthawi yopukutira yonyowa ndi youma zinafufuzidwa mu kafukufukuyu. Avereji ya m'mimba mwake (D), muyeso wa kukula kwa tinthu, inayerekezeredwa pakati pa kugaya konyowa ndi kouma. Kusweka kwa zinthu kunathandiza kuti tinthu timeneti tipangidwe panthawi yopukutira yonyowa. Mofananamo, kugaya kouma kunathandiza kuchepetsa m'mimba mwake wa tinthu tolemera.
Zotsatira za kuchulukana kwa zinthu ndi kuyenda bwino kwa zinthu zinaphunziridwanso. Zinthu izi ndizofunikira kwambiri pa ntchito ya mphero. Zimakhudzanso kulongedza tinthu mkati mwa mphero. Kuyenda bwino kwa zinthu kumakwera ndi madzi, zomwe zimathandiza kuti tinthu tifalikire.
Ngakhale kuti mapangidwe a zingwe amawonjezeka ndi kusweka, koma zinthu zopepuka sizimachepa. Zinthu zomwe zinayesedwa zinali malasha, chitsulo, manganese, ndi dolomite. Zinakonzedwa kwa maola awiri mu mphero ya mpira ya labotale. Pambuyo popera, zinthuzo zinasefedwa pa 1mm. Kupanga zingwe kunayesedwa pogwiritsa ntchito ma sieve awa.
D80 inachepetsedwa ndi ma microns 30-40 pambuyo powonjezera liwiro la mphero ndi mayunitsi 15. Mofananamo, pa zitsulo zachitsulo, kuwonjezeka kofanana kwa D80 kunali 15.8%. Gawo la manganese pansi pa 0.053mm linakwera ndi 15.6%. Mofananamo, gawo la dolomite pansi pa 0.031mm linakwera ndi 16.9%.
Kuphatikiza apo, kukwera kwa chiŵerengero cha L/D ndi chizindikiro chachikulu cha mawonekedwe a tinthu tating'onoting'ono. Miyala yachitsulo ili ndi tinthu tating'onoting'ono tosanjikizana, pomwe miyala ya malasha, dolomite, ndi manganese ili ndi tinthu tating'onoting'ono tozungulira. Kusagwirizana kumeneku kukuwonetsa kuti mawonekedwe a tinthu tating'onoting'ono adakhudza kwambiri kupanga tinthu tating'onoting'ono.
Pomaliza, kusanthula kukula kunachitika pogwiritsa ntchito makulidwe osiyanasiyana a sieve. Mapaketi asanu ndi limodzi olemera 1kg adagwiritsidwa ntchito onse. Kafukufukuyu adawonetsa kuti tinthu tating'onoting'ono tambirimbiri mu mphero ndi tomwe tidagwira ntchito yofunika kwambiri podziwa kusalala kwa chopukusiracho.
Mitundu yosiyanasiyana ya mphero imagwiritsidwa ntchito ngati chindapusa chachikulu mphero yopera Makina. Mtundu uliwonse uli ndi ubwino wake. Ndikofunikira kusankha yoyenera kugwiritsa ntchito. Muyeneranso kuyang'ana ubwino wa zinthuzo. Kulimba, kumamatira, kukhazikika kwa mankhwala, ndi mphamvu yokoka ndi zitsanzo.
Mwachitsanzo, ngati chinthu chanu chili bwino kwambiri, mungafune kuyesa jetmill. Jetmill imafulumizitsa tinthu ting'onoting'ono totsutsana wina ndi mnzake komanso pamwamba pa mphero. Amaganiziridwa kuti ndi osunga mphamvu zambiri kuposa ma ballmill. Komabe, sakulangizidwa kuti aswe quartz.
Makina opangira jetmill, makina opangira zotsalira, ndi makina opangira ma pin ndi zitsanzo za zida zopangira zopera bwino. Zipangizozi zimatha kusunthidwa kapena kukhazikitsidwa kosatha, kutengera zosowa zanu.
Mafakitole ena amapangidwa kuti azigwira ntchito yonyamula katundu wambiri. Ena amatha kupukutidwa kosatha. Mosasamala kanthu za mtundu wa fakitole, muyenera kutsimikiza kuti makina anu ali ndi mphamvu zambiri. Kukula kwa chakudya kumatsimikizira mphamvu.
Kawirikawiri, muyenera kuyamba ndi cholumikizira chachikulu. Tinthu tating'onoting'ono tikafika kukula kwinakwake, sinthani kukhala cholumikizira chaching'ono. Mphamvu yofunikira pogaya tinthu tating'onoting'ono imawonjezeka pamene kukula kwake kumachepa.
Kugwiritsa ntchito njira yopera pang'ono kungachepetse kuchuluka kwa zinthu zopangira zomwe zingatayike. Kuphatikiza apo, mutha kupewa kuipitsidwa ndi chitsulo chachitsulo. Njirazi zimathandizanso pothana ndi kutentha.
Kupera kosalala kwambiri kungathandizenso kuti zinthu ziyende bwino. Mutha kusintha kukula kwa tinthu pogwiritsa ntchito zida zopera zosalala kwambiri. Chifukwa chake, mutha kukhala ndi chidaliro kuti mudzatha kupanga chinthu chapamwamba kwambiri chomwe chili ndi zolakwika zochepa kwambiri.
Kusankha makina oyenera opera bwino kwambiri ndikofunikira kwambiri kuti zinthu ziyende bwino. Kaya mukugwiritsa ntchito makina opangira jet, makina opangira zinthu zotayira, kapena makina opangira zinthu zotayira, muyenera kuganizira za kapangidwe ka zinthu zanu. Kupatula kuuma, muyeneranso kuganizira za kuuma, kukhuthala, kapangidwe kake, komanso kutentha kosungunuka.
Muyeneranso kuganizira za mtengo wa mphamvu yopera. Ngati mukufuna kupera bwino kwambiri, muyenera kuganizira za mtengo wa kuwonongeka ndi kung'ambika kwamphamvu.
Tencan ili ndi malo ake opangira zinthu okwana masikweya mita 20,000 komanso malo ofufuzira ndi chitukuko okwana masikweya mita 22,000. Tencan ili ndi mitundu isanu ya zinthu yokhala ndi mitundu yoposa 40 ndi zida zosinthira zosiyanasiyana zopitilira 400 ndi zowonjezera kuti ikwaniritse zosowa zonse za makasitomala ake. Tencan yagwirizana ndi madokotala 20 ochokera ku mayunivesite asanu otchuka ndipo yapeza ma patent opitilira 30.
Kupanga zida za ufa ndi ukadaulo wa ufa ndi mabizinesi akuluakulu a kampaniyo. Zinthu zathu zazikulu zomwe timagwiritsa ntchito panopa zikuphatikizapo mitundu yonse ya Chigayo cha mpira cha mapulaneti cha Laboratory ndi makina ophwanyira ndi opera owunikira, kusakaniza, ndi kuwunikira zida, komanso zida zina za labotale monga mabokosi a magolovesi, zida zasayansi, ndi zinthu zina zambiri.
